STRAIGHT ampLEVEL by Espie Butch Joyce

How do you hold a party for a large number of people when you dont know their travel plans and they don t send in a RSVP card If youre one of the many EAA volunteers and divishysion officers you go to the EAA Oshkosh Convention on the job training (OJT) for 10 to 15 years and then the best educated W AG is sometimes not good enough

EAA Oshkosh 94 will go down as a record year for the number of peoshyple and aircraft parked in the AnshytiqueClassic area of the Convention grounds Not only does the Parking Committee have to deal with our Anshytique Classic and Contemporary airshycraft they also must deal with speshycialty aircraft group parking and show plane camping Show plane camping includes all show planes (Homebuilts Warbirds Antique Classic and Conshytemporary aircraft)

In the AntiqueClassic area alone during EAA Oshkosh I have nearly 60 Chairmen and Co-Chairmen who are in charge of different activities Volunteers who help these chairpeoshy

pie number around 350 people All of these amazing people put in nearly 14000 man-hours of labor over a two week period

We have our bumps in the road and sometime we get awfully close to the ditch but over all things run amazshyingly smooth I am not laying out these large numbers to make excuses for any member who was not happy with their visit to EAA Oshkosh 94 We certainly understand that certain aspects of the camping situation were not optimum and you can be assured that discussions are already taking place to help change things for the better We are constantly working to remedy any of our problem areas Sometimes we can only correct these situations if we are told about it in a coherent fashion Anyone who has any constructive comments please let me hear from you - these items are talked about

The number of Antiques present this year was just a bit higher than the past couple of years The number of classics increased by approximately

15 Contemporary aircraft also inshycreased in numbers

Towards the end of the Convention I was talking with the Chief Judges for the Antique Classic and Contemposhyrary airplanes The quality of restorashytions continues to improve Dan Knutson Contemporary Chief Judge writes that in the two short years weve been judging this class we are very pleased with the increase in the quality of the aircraft as well as the improvement overall The owners of these planes have been very enthusishyastic in upgrading and improving their airplanes Heres to yet another sucshycessful Convention Im already lookshying forward to Oshkosh 95 I feel that Dans feelings fairly well reflect feelings of the volunteers who make your Convention successful

One important thing that will keep the AntiqueClassic Division strong is a good strong membership so ask your buddy to join up with us Let s all pull in the same direction for the good of aviation Remember we are better toshygether Join us and have it all

(3IWf EAA APPLAUDS ENACTMENT OF NEW GENERAL A VlATlON

LIABILITY LAW

Just as this issue was being readied for publication we were pleased to learn that President Clinton had signed the General Aviation liability Statute of Repose bill on August 17 1994 This landmark legislashytion creating an 18 year statute of repose for all general aviation aircraft built with fewer than 20 seats is the type of law that EAA and other aviation industry groups have been working towards for over a decade

Only GA manufacturers will be imshypacted by the new law not those who reshypair or rebuild ai rcraft and lawsuits curshyrently on file will not be affected by the legislation

EAA president Tom Poberezny had this to say about th e signing of the new law by the President

We are very pl ease d that the long fight to enact general aviation liability reshyform has been successful We congratushylate Edward Stimpson president of the General Aviation Manufacturers Associashytion Senator Nancy Kassemaum (RshyKansas) Representative Dan Glickman (D-Kansas) Representative Jim Hansen (R-Utah) and all the others who have worked to help pass this legislation EAA has maintained that perpetual liability has discouraged manufacturers from continushying to build single-engine private aircraft and has also prevented the emergence of new designs innovations and technologies for general aviation We see this measure is another step in revita lizi ng Americas general aviation industry

A broader base of type certificated airshycraft means a wider range of eq uipm ent and accessories available for use on our vintage ai rplanes - for instance what comshypany will be the first to offer a reasonably priced solid-state ignition system for certishyfied a ircraft While this legislation (or any legislation for that matter) should not be considered the be all end all cure all to general aviations ills its certainly a big step in the right direction Lets all hope it heralds th e beginnin g of the recovery to that segment of the aviation industry

PARKS OPEN HOUSE

splendid business A number of landshying fields have been established by the latter within a radi us of 60 miles of these points and in addition to making a great many joy hops the inland dealshy

ers are making a number of short passhysenger flights up to 100 miles distance

The operation in Florida of the Hshy16 type is really the first experiment in this country of a transportation operashy

per air mile per passenger A notable feature of the transshy

portation business and one that will be particularly interesting to the aeronaushytic industry is the fact that a number of people have repeated taking long flights showing that it is not purely for novelty but rather both enjoyable and permitting quick communication beshytween points

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

PROHIBITION

What is omitted from the above artishycle abo ut the popularity of flying in Florida was prohibition The unpopular law made the Bahama Islands and Cuba a mecca for thirsty Americans

America Trans-Oceanic was only one passenger service formed to meet the new demand for transportation to the Bahamas Others included Chalks Aero Limited and Florida West Indies Airways (later Aeromarine Airways) The Bimini Bay Rod and Gun Club was formed by some wealthy Miamians osshytensibly to provide a fishing and shootshying club on Bimini Island only 50 miles off-shore from Miami and in British Territory To this end the club built a 100 room clubhouse on the island supshyported the America Trans-Oceanic flyshying boat operations and put into service a 150 foot steam yacht for transportashytion to the island

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

ing the operations of the Big Fish were taken from an album of John Whitney Whitney was an employee of Curtiss

who was sent to Palm Beach to help with flying boat operations He proshyvided public relations advertising and operational support The pictures reshyproduced were taken during early 1920 and the captions provided came from information in the album We are fortunate that his son John Whitshyney of Fort Wayne IN was considershyate enough to loan the album so that some of the photos could be reproshyduced for this article and for our photo archives

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

Charles Sylvias Cessna 1708

The photos of this very nice 1955 Cessna 170B N3590C SIN 26634 were sent in by owner Charles Sylvia (EAA 446109 A IC 21377) of Middleboro MA Charles and his wife Connie have been extremely busy upgrading the four-placer to full IFR certification since purchasing the 170 in June of 1993 Powered with a Continental 0shy300 engine of 145 hp swinging a McshyCauley polished propeller the 170 has had a new paint job on the outside and a new interior inside Other amenities include new engine baffling Jasco 50

The photo of this 1947 Cessna 140 N2084V SIN 14300 with its Gee Bee inspired paint scheme was sent in by owner Don Alesi (EAA 371460 AIC 16315) of Dundee IL Don reshyports the Cessna was restored over a period of eight months by his wife Maureen his brother Bob Alesi and himself The 140 was painted with the Superflite System II from Cooper usshying Juneau White and Rasberry Red The color scheme was devised to make the airplane highly visible - and look fast while standing still Fienshyfield Aviation of Lake-In-The-Hills Airport helped with rigging and final assembly The first flight was May 10 1994 and it flew hands off This airshyplane was on line at Spring City

amp alternator El Reno spin-on oil filshyter new instruments and complete new wiring harness using circuit breakers instead of fuses A Precise Flight standby vacuum system augments the venturi system All avionics were upshygraded to IFR standards and include a Garmin 95AVD GPS which Charlie says is the answer to a navigator s prayers It uses an outside antenna which helps with the cabin clutter

Unique to this 170 is a set of the origishynal Goodyear brakes and wheels that have the Goodyear crosswind landing gear installed allowing the airplane to land in a crab For new passengers who have never experienced landing sideways it is indeed an elevation of the pucker factor Next on Charlies want-list are a Vernier mixture conshytrol heated pitot and a Whelen double flash beacon on the belly

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

STRAIGHT ampLEVEL by Espie Butch Joyce

How do you hold a party for a large number of people when you dont know their travel plans and they don t send in a RSVP card If youre one of the many EAA volunteers and divishysion officers you go to the EAA Oshkosh Convention on the job training (OJT) for 10 to 15 years and then the best educated W AG is sometimes not good enough

EAA Oshkosh 94 will go down as a record year for the number of peoshyple and aircraft parked in the AnshytiqueClassic area of the Convention grounds Not only does the Parking Committee have to deal with our Anshytique Classic and Contemporary airshycraft they also must deal with speshycialty aircraft group parking and show plane camping Show plane camping includes all show planes (Homebuilts Warbirds Antique Classic and Conshytemporary aircraft)

In the AntiqueClassic area alone during EAA Oshkosh I have nearly 60 Chairmen and Co-Chairmen who are in charge of different activities Volunteers who help these chairpeoshy

pie number around 350 people All of these amazing people put in nearly 14000 man-hours of labor over a two week period

We have our bumps in the road and sometime we get awfully close to the ditch but over all things run amazshyingly smooth I am not laying out these large numbers to make excuses for any member who was not happy with their visit to EAA Oshkosh 94 We certainly understand that certain aspects of the camping situation were not optimum and you can be assured that discussions are already taking place to help change things for the better We are constantly working to remedy any of our problem areas Sometimes we can only correct these situations if we are told about it in a coherent fashion Anyone who has any constructive comments please let me hear from you - these items are talked about

The number of Antiques present this year was just a bit higher than the past couple of years The number of classics increased by approximately

15 Contemporary aircraft also inshycreased in numbers

Towards the end of the Convention I was talking with the Chief Judges for the Antique Classic and Contemposhyrary airplanes The quality of restorashytions continues to improve Dan Knutson Contemporary Chief Judge writes that in the two short years weve been judging this class we are very pleased with the increase in the quality of the aircraft as well as the improvement overall The owners of these planes have been very enthusishyastic in upgrading and improving their airplanes Heres to yet another sucshycessful Convention Im already lookshying forward to Oshkosh 95 I feel that Dans feelings fairly well reflect feelings of the volunteers who make your Convention successful

One important thing that will keep the AntiqueClassic Division strong is a good strong membership so ask your buddy to join up with us Let s all pull in the same direction for the good of aviation Remember we are better toshygether Join us and have it all

(3IWf EAA APPLAUDS ENACTMENT OF NEW GENERAL A VlATlON

LIABILITY LAW

Just as this issue was being readied for publication we were pleased to learn that President Clinton had signed the General Aviation liability Statute of Repose bill on August 17 1994 This landmark legislashytion creating an 18 year statute of repose for all general aviation aircraft built with fewer than 20 seats is the type of law that EAA and other aviation industry groups have been working towards for over a decade

Only GA manufacturers will be imshypacted by the new law not those who reshypair or rebuild ai rcraft and lawsuits curshyrently on file will not be affected by the legislation

EAA president Tom Poberezny had this to say about th e signing of the new law by the President

We are very pl ease d that the long fight to enact general aviation liability reshyform has been successful We congratushylate Edward Stimpson president of the General Aviation Manufacturers Associashytion Senator Nancy Kassemaum (RshyKansas) Representative Dan Glickman (D-Kansas) Representative Jim Hansen (R-Utah) and all the others who have worked to help pass this legislation EAA has maintained that perpetual liability has discouraged manufacturers from continushying to build single-engine private aircraft and has also prevented the emergence of new designs innovations and technologies for general aviation We see this measure is another step in revita lizi ng Americas general aviation industry

A broader base of type certificated airshycraft means a wider range of eq uipm ent and accessories available for use on our vintage ai rplanes - for instance what comshypany will be the first to offer a reasonably priced solid-state ignition system for certishyfied a ircraft While this legislation (or any legislation for that matter) should not be considered the be all end all cure all to general aviations ills its certainly a big step in the right direction Lets all hope it heralds th e beginnin g of the recovery to that segment of the aviation industry

per air mile per passenger A notable feature of the transshy

portation business and one that will be particularly interesting to the aeronaushytic industry is the fact that a number of people have repeated taking long flights showing that it is not purely for novelty but rather both enjoyable and permitting quick communication beshytween points

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

PROHIBITION

America Trans-Oceanic was only one passenger service formed to meet the new demand for transportation to the Bahamas Others included Chalks Aero Limited and Florida West Indies Airways (later Aeromarine Airways) The Bimini Bay Rod and Gun Club was formed by some wealthy Miamians osshytensibly to provide a fishing and shootshying club on Bimini Island only 50 miles off-shore from Miami and in British Territory To this end the club built a 100 room clubhouse on the island supshyported the America Trans-Oceanic flyshying boat operations and put into service a 150 foot steam yacht for transportashytion to the island

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

(3IWf EAA APPLAUDS ENACTMENT OF NEW GENERAL A VlATlON

LIABILITY LAW

Just as this issue was being readied for publication we were pleased to learn that President Clinton had signed the General Aviation liability Statute of Repose bill on August 17 1994 This landmark legislashytion creating an 18 year statute of repose for all general aviation aircraft built with fewer than 20 seats is the type of law that EAA and other aviation industry groups have been working towards for over a decade

Only GA manufacturers will be imshypacted by the new law not those who reshypair or rebuild ai rcraft and lawsuits curshyrently on file will not be affected by the legislation

EAA president Tom Poberezny had this to say about th e signing of the new law by the President

We are very pl ease d that the long fight to enact general aviation liability reshyform has been successful We congratushylate Edward Stimpson president of the General Aviation Manufacturers Associashytion Senator Nancy Kassemaum (RshyKansas) Representative Dan Glickman (D-Kansas) Representative Jim Hansen (R-Utah) and all the others who have worked to help pass this legislation EAA has maintained that perpetual liability has discouraged manufacturers from continushying to build single-engine private aircraft and has also prevented the emergence of new designs innovations and technologies for general aviation We see this measure is another step in revita lizi ng Americas general aviation industry

A broader base of type certificated airshycraft means a wider range of eq uipm ent and accessories available for use on our vintage ai rplanes - for instance what comshypany will be the first to offer a reasonably priced solid-state ignition system for certishyfied a ircraft While this legislation (or any legislation for that matter) should not be considered the be all end all cure all to general aviations ills its certainly a big step in the right direction Lets all hope it heralds th e beginnin g of the recovery to that segment of the aviation industry

portation business and one that will be particularly interesting to the aeronaushytic industry is the fact that a number of people have repeated taking long flights showing that it is not purely for novelty but rather both enjoyable and permitting quick communication beshytween points

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

PROHIBITION

What is omitted from the above artishycle abo ut the popularity of flying in Florida was prohibition The unpopular law made the Bahama Islands and Cuba a mecca for thirsty Americans

America Trans-Oceanic was only one passenger service formed to meet the new demand for transportation to the Bahamas Others included Chalks Aero Limited and Florida West Indies Airways (later Aeromarine Airways) The Bimini Bay Rod and Gun Club was formed by some wealthy Miamians osshytensibly to provide a fishing and shootshying club on Bimini Island only 50 miles off-shore from Miami and in British Territory To this end the club built a 100 room clubhouse on the island supshyported the America Trans-Oceanic flyshying boat operations and put into service a 150 foot steam yacht for transportashytion to the island

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

per air mile per passenger A notable feature of the transshy

portation business and one that will be particularly interesting to the aeronaushytic industry is the fact that a number of people have repeated taking long flights showing that it is not purely for novelty but rather both enjoyable and permitting quick communication beshytween points

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

PROHIBITION

What is omitted from the above artishycle abo ut the popularity of flying in Florida was prohibition The unpopular law made the Bahama Islands and Cuba a mecca for thirsty Americans

America Trans-Oceanic was only one passenger service formed to meet the new demand for transportation to the Bahamas Others included Chalks Aero Limited and Florida West Indies Airways (later Aeromarine Airways) The Bimini Bay Rod and Gun Club was formed by some wealthy Miamians osshytensibly to provide a fishing and shootshying club on Bimini Island only 50 miles off-shore from Miami and in British Territory To this end the club built a 100 room clubhouse on the island supshyported the America Trans-Oceanic flyshying boat operations and put into service a 150 foot steam yacht for transportashytion to the island

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

ing the operations of the Big Fish were taken from an album of John Whitney Whitney was an employee of Curtiss

who was sent to Palm Beach to help with flying boat operations He proshyvided public relations advertising and operational support The pictures reshyproduced were taken during early 1920 and the captions provided came from information in the album We are fortunate that his son John Whitshyney of Fort Wayne IN was considershyate enough to loan the album so that some of the photos could be reproshyduced for this article and for our photo archives

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Tom Mangans Aeronca Champion 7CCM

N2182E SIN

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

portation business and one that will be particularly interesting to the aeronaushytic industry is the fact that a number of people have repeated taking long flights showing that it is not purely for novelty but rather both enjoyable and permitting quick communication beshytween points

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

PROHIBITION

What is omitted from the above artishycle abo ut the popularity of flying in Florida was prohibition The unpopular law made the Bahama Islands and Cuba a mecca for thirsty Americans

America Trans-Oceanic was only one passenger service formed to meet the new demand for transportation to the Bahamas Others included Chalks Aero Limited and Florida West Indies Airways (later Aeromarine Airways) The Bimini Bay Rod and Gun Club was formed by some wealthy Miamians osshytensibly to provide a fishing and shootshying club on Bimini Island only 50 miles off-shore from Miami and in British Territory To this end the club built a 100 room clubhouse on the island supshyported the America Trans-Oceanic flyshying boat operations and put into service a 150 foot steam yacht for transportashytion to the island

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

ing the operations of the Big Fish were taken from an album of John Whitney Whitney was an employee of Curtiss

who was sent to Palm Beach to help with flying boat operations He proshyvided public relations advertising and operational support The pictures reshyproduced were taken during early 1920 and the captions provided came from information in the album We are fortunate that his son John Whitshyney of Fort Wayne IN was considershyate enough to loan the album so that some of the photos could be reproshyduced for this article and for our photo archives

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

per air mile per passenger A notable feature of the transshy

portation business and one that will be particularly interesting to the aeronaushytic industry is the fact that a number of people have repeated taking long flights showing that it is not purely for novelty but rather both enjoyable and permitting quick communication beshytween points

At Palm Beach the America Trans-Oceanic Company has estabshylished a mammoth hangar with facilishy

ties to accommodate fifteen machines Seven machines are now there includshying Mr ERThomas four-passenger Curtiss Flying Boat

A regular schedule is maintained from the Company s hangars at Miami to Bimini Four trips a week are made to this point and members of the Anshygier Fishing Club of Miami have found it very convenient as it enables them to leave Miami early in the morning enshyjoy a whole days fishing at Bimini and return about six o clock

In all overseas operations it is necshyessary to obtain clearance papers for the flying boats the same as those reshyquired by steamships and all passenshygers must have passports This obstacle has been reduced by the Company so that the entire formalities can be disshypensed with in less than one hour that is a passengers photograph made passport obtained and clearance pashypers for the flying boat properly filed

PROHIBITION

What is omitted from the above artishycle abo ut the popularity of flying in Florida was prohibition The unpopular law made the Bahama Islands and Cuba a mecca for thirsty Americans

America Trans-Oceanic was only one passenger service formed to meet the new demand for transportation to the Bahamas Others included Chalks Aero Limited and Florida West Indies Airways (later Aeromarine Airways) The Bimini Bay Rod and Gun Club was formed by some wealthy Miamians osshytensibly to provide a fishing and shootshying club on Bimini Island only 50 miles off-shore from Miami and in British Territory To this end the club built a 100 room clubhouse on the island supshyported the America Trans-Oceanic flyshying boat operations and put into service a 150 foot steam yacht for transportashytion to the island

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

ing the operations of the Big Fish were taken from an album of John Whitney Whitney was an employee of Curtiss

who was sent to Palm Beach to help with flying boat operations He proshyvided public relations advertising and operational support The pictures reshyproduced were taken during early 1920 and the captions provided came from information in the album We are fortunate that his son John Whitshyney of Fort Wayne IN was considershyate enough to loan the album so that some of the photos could be reproshyduced for this article and for our photo archives

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

VINTAGE AIRPLANE 13

An investigation revealed the Rangershypowered Fairchild which was registered in Argentina as LV-AFH has about 1900 hours total time on the airframe and had last been used to haul parachute jumpers in the late 1960s Roy hopes to restore the airplane to flying condition and possibly fly it to EAA Oshkosh 95 (his 40th birthday) We wish Roy and his crew the very best as they restore this beautiful cabin Fairchi ld to flying condishytion

(Left) With a platform to fasten the engine to the Ranger is tipped to the vertical complete with oil tank and engine mount and readied for shipping to the U S That s Richard Macaferty smiling at the accomplishment Note the round oil cooler with its atshytendant air inlet from the nosecowl and exhaust on the righthand side of the engine cowling

Carefully placed on a flatbed truck the fuselage and engine complete w ith cowling are ready for transport to the seaport in Buenos Aires where the entire Fairchild was fitted into a 20-foot container for shipment to California We look forward to seeing Roy and his jewel at Oshkosh

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

AMERICA TRANS-OCEANIC COMPANY

It has been he ld tha t most of the commercial flying companies in the United States date from the spring of 1919 One notable exception was the America Trans-Oceanic Company which was formed in 1916 when Glenn H Curtiss and Rodman Wanamaker resurrected their plans to cross the Atshylantic that had originated in the conshystruction of the flying boatAmerica Early after solving the problem of takeoff from water Glenn Curtiss had bee n convinced that the Atlantic would be crossed by airplane There had been discussions of the possibility with Rodman Wanamaker at the Aero Club in New York and with Lieutenant John Towers Naval aviator number three

Wanamaker put up $25000 for the construction a flying boat capable of flying the Atlantic The aircraft the largest flying boat of its day and the first twin-engined flying boat was called the America An order for two machines was p laced in August 1913 Complet e d in the summer of 1914 the machine was put through its paces and was in place for an Atlantic crossing in August 1914 when the start of the war in Europe put an end to the project but not the dream

Formed in 1916 with the idea of eventually providing overseas passenshy

at Port Washington Long Island and Palm Beach Florida During 1916 opshyerations were carried on for pleasure and sport purposes but the demand was not sufficient to warrant expansion even if the war had not intervened

Soon after the end of the war the company many of whose flyers had served in Naval Aviation took over a number of Curtiss flying boats and reshybuilt them into passenger planes In the fall of 1919 a war surplus Curtiss H-16 was shipped from Philadelphia to West Palm Beach The aircraft was asshy

sembled and converted into a 12 passhysenger ship When the conversion was completed an unusual decorative scheme was devised for the craft It took the form of a fish with scales and a large gaping tooth-filled mouth and and was named the Big Fish

The H-16 had a wing span of 95 feet and a hull length of 43 feet Power was supplied by two 12-cylinder Liberty engines of 350 hp However notes in the album of John Whitney indicated that new domed type pistons were inshystalled raising the horsepower to 400

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

ing the operations of the Big Fish were taken from an album of John Whitney Whitney was an employee of Curtiss

who was sent to Palm Beach to help with flying boat operations He proshyvided public relations advertising and operational support The pictures reshyproduced were taken during early 1920 and the captions provided came from information in the album We are fortunate that his son John Whitshyney of Fort Wayne IN was considershyate enough to loan the album so that some of the photos could be reproshyduced for this article and for our photo archives

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Tom Mangans Aeronca Champion 7CCM

N2182E SIN

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Conversion for passenger use placed two seats in the bow compartshyment and nine in the hull in two sepashyrate areas With a fuel capacity of 235 gallons the flying boat could operate at a speed of 75 mph for about 5-112 hours The first flight with passengers to Bimini was made on February 24 1920 While the Big Fishs flights between Florida and the various isshylands of the Bahamas were essentially barnstorming ventures they served an historic purpose the tri-weekly flights

between Miami and Bimini pioneered scheduled overseas airline transportashytion from America At a rate of $25 each way passengers could dash over to Bimini in a little more than half an hour The Big Fish departed from Miami at 2 pm on Wednesdays Frishydays and Sundays returning on the same hour on Thursdays Saturdays and Mondays The flying boat operashytion in Florida was under the direction of David McCullough who was one of the pilots of the Navy transatlantic flyshy

ing boat NC-3 The crew of the Big Fish was George A Page and Randy Baldwin The two had earlier worked together in the A S Heinrich airplane facshytory During the war Page joined with Curtiss in his booming flying boat business and Baldshywin moved to the Naval Aircraft Factory Thus when they were hired by McCullough Page as a pilot and Baldwin as a mechanic they were well versed in the lore of flyi ng boats

The H-16 flying boat operated for two seashysons in Florida before returning north in the summer of 1921 where it engaged in passenger work in upper New York state As a result of a hard landing on the Hudson River the botshytom of the hull gave away The aircraft was beached and then stripped This was the end of the America Trans-Oceanics big flyshying boat operations They carried on with smaller planes for a few more years

During five years of operations the company had carried over 5000 passengers approxishymately 300000 miles without a single accishydent harming passenshygers or crew Quite a start to commercial sershyvice in America

The photos illustratshy

ing the operations of the Big Fish were taken from an album of John Whitney Whitney was an employee of Curtiss

who was sent to Palm Beach to help with flying boat operations He proshyvided public relations advertising and operational support The pictures reshyproduced were taken during early 1920 and the captions provided came from information in the album We are fortunate that his son John Whitshyney of Fort Wayne IN was considershyate enough to loan the album so that some of the photos could be reproshyduced for this article and for our photo archives

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

In Part II next month Ill cover a few antenna types and their installation in aircraft

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

An investigation revealed the Rangershypowered Fairchild which was registered in Argentina as LV-AFH has about 1900 hours total time on the airframe and had last been used to haul parachute jumpers in the late 1960s Roy hopes to restore the airplane to flying condition and possibly fly it to EAA Oshkosh 95 (his 40th birthday) We wish Roy and his crew the very best as they restore this beautiful cabin Fairchi ld to flying condishytion

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

Aircraft Antennas For The Pilot

by Bill Butters Technical Coordinator Advanced Aircraft Electronics Inc

Most of us spend a lot of time studyshying selecting planning budgeting for and finally buying our avionics package The extent of our final selection can range from a handheld transceiver to a full IFR suite In all cases the radios will require an antenna to transmit and receive information In most cases we select the antenna much like wed select a tire or spark plug - we pick the one with the best price and quickest delivshyery This discussion is presented to ofshyfer the ownerrebuilder insight into the VHF antenna world and thus help him to better select the antennas

Lets briefly decipher the mysteries of a radio communication system

Wave Generation

During transmit antennas are used to convert radio frequency e lect rical current that is developed in the radio system to e lectric and magnetic waves which radiate in the air (remember the old term airwaves) During receivshying these electric and magne tic waves (call them EM [electromagnetic] waves) are intercepted by the antenna and are co nv ert ed to RF e lec trical current which the radio can recognize

A reasonable analogy is to imagine that you re sitting in a small boat on a quiet pond and have yo ur fishing rod with a float in the water Somewhere out of sight a fish sp lashes and ripples radiate outwards Sitting in your boat you notice that the float moves up and down slightly If the fish is too far away the ripples are too small and you never see any float movement

Likewise imagine that you re in your airplane cruising smoothly along Someshywhere someone calls Flightwatch lookshying for weather information His E M waves radiate out in all directions and if youre within range the signal is strong enough to be picked up and you receive the transm ission Your antenna and the float have closely related functions

Noise

Back at the pond all is well until yo u put a n oar in th e water o r sta rt your trolling motor Now you are makshy

ing large ripples of your own This self generated interfe rence is many times stronger than the incoming ripples and can mask the signal you need to detect from the fish Your float (like your anshytenna) now sees mostly your own ripshyples (noise) Equate your trolling moshytor with ignition noise strobe noise alternator noise and similar self genershyated static

Polarity

To continue the analogy let s deshyscribe polarity

When the ripples radiated outwards from the so urce they passed by th e float which responded We notice that the up and down ripple action causes an up and down float action

What if you used a float that only could move rightl eft (imagination stre tch is required he re) The ripple moves by this new float and it hardly moves in fact it will only move slightly if the wave is quite large compared to the fish ripple This response is similar to the situation found in the VHF comshymunication and VOR naviga tion sigshynals and is termed polarization

In the world of antennas the comshymunication antenna is always vertical a nd so a ll communication signals are polarized in th e vertical plane This means that the ante nna responds best to RF waves that oscillate in th e updown direction For VOR navigashytion the antennas are horizontally poshylarized to match the hori zontal polarshyization of the signa ls They mos tl y respond to RF waves th at oscillate in the direction para llel to the Earth

Tuning

When the fish splashed and created ripples the fl oat respond e d to th e waves pass ing by But yo u a lso realshyized that while sitting in the boat you didnt fee l movement In this case we know that the boat length compared to t he high ripple frequency (space beshytween waves or wavelength is re lated to the freque ncy) was too large to reshyspond to the rapid interval of the wave crests

In another case if a wake from anshyother boat passes by us (this wave has much large r distances be tween crests and thus a low frequency) our boat reshysponds with expected up and down movement

What s illustrated here The princishyple th a t to best d e tect the incoming waves we should have a sensor or anshytenna that is designed to respond to the frequency of the waves

In your aircraft your antennas are sized (electrically tuned) to respond to certain frequencies Smaller antennas are best suited for highe r frequencies and as the frequencies become lower the corresponding wavelength is longer and the antennas become longer as well At some point the size of the low frequency antenna becomes too large to be practical so electrical devices are used to lengthen the antennas electrishycal equivalent size in order to keep its physical length within reason Knowshying this you realize that the transponshyder antenna (small) cannot be used as a communication antenna (larger)

Impedance Matching

If you liked the fishing analogy you ll love th e next one Think billiards We ll use thi s ana logy to illustrate Standing Wave Ratio (SWR) SWR is a measurement used to describe how efshyfective the antenna is when conve rting incoming RF radiat ion to electric curshyrent and how well it converts outgoing radio current to RF radiation

We re at the billiard table and the 8 ball is analogous to the RF energy we want to leave the ante nna and broadshycast (travel) out away from us T he cue ball is like the radio s electrical energy that is sti ll inside the radio and is to be transmitted The cue ball has electrical energy and contains voice information but it isn t in the proper e lectrical form to broadcast The laws of physics tell us that maximum e ne rgy transfers when impedances of two systems are matched System one is our radio with electrical currents circulating internally (radio is the cue ball) System two is the antenna (the 8 ball) with its ability to launch or broadcast RF

VINTAGE AIRPLANE 9

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Cue Ball 8 Ball 8 Ball Moving (Left) A well matched pair of billiard balls illustrates the concept of proper impedance in an electrical circuit

(Below) Using a tennis ball in our bilshyliards analogy shows how a poorlyRadio ~I~ IAntenna I matched antenna and radio will re-

Signal sult in a poor transfer of energy

We key the mike and send electrical current along the 50 ohm coax cable (in our analogy the radio cue ball rolls to the antenna eight ball and hits it straight on) The electrical current flows in the antenna and the RF radishyates out in all directions (in the analogy the cue ball information hits the 8 ball antenna and stops dead while the 8 ball rolls away and drops in to the pocket shyall of the energy from the cue ball is transferred to the 8 ball) Here we have maximum transfer of energy electrical in the radio and mechanical in our analshyogy but similar in their action

Now set up the same billiard condishytion but substitute a tennis ball for the cue ball When we transmit the electrishycal energy the radio energy (tennis ball) hits the antenna (8 ball) and the tennis ball bounces back at you while the 8 ball dribbles forward a small distance This is a classic case of impedance mismatch with the resultant poor transfer of enshyergy

Now look at the third case where the solid 8 ball is replaced with a second tennis ball Now the total radio energy (tennis ball No1) can be transferred to the antenna (second tennis ball No2) when the two collide With the two identical balls the match requirement is satisfied and total energy transfer ocshycurs

A similar condition is happening in the radio system when impedances don t match well If the match is poor beshytween the antenna and the radio system the outgoing radio energy is reflected back into the transmitter In some cases this condition could be damaging or could cause self-protect circuits to actishyvate and shut down the radio The minshyimum consequence is that your transshymissions are garbled and lack range

VSWR

SWR (Standing Wave Ratio) is one specification that tells you how well the antenna performs The industry stanshydard for impedances on our radios is 50 ohms so the closer we match to this value the better the antenna performs The connection to the radio is made with coaxial cable because this style of cable efficiently supports RF propagashytion We use RG 58 AU which has an impedance of 50 ohms and thus proshyvides a good impedance match when connected to the radio

The table on the left gives an indicashytion of how much power can be reflected back into the radio when the SWR (imshypedance match) isnt what it should be

The antenna can be a design that has a poor SWR but still is tuned to the deshysired VHF frequencies When transmitshyting the antenna system is trying to reshyspond to the RF signa ls being transmitted but because of the poor SWR much of the energy is reflected back into the radio transmitter A remshyedy for this condition is to place small ferrite rings around the coaxial cable out near the antenna These rings act as chokes or e lectrical barriers which abshysorb the unradiated energy and reduce the amount of RF energy that could be reflected back into your radio The reshysult is that your transmission and recepshytion is weak but the quality of the inforshymation is less garbled

Your antennas a re reciproca l d eshyvices This means that all of the electrishycal terms that describe it s operating characteristics are valid for both transshy

mission and reception So if you have an effective antenna for transmission then it follows that the same antenna will be effective for reception

We now know that we must have an antenna that is designed for the required frequencies of our radios and that the lower the SWR value the better the performance We also learned that the communications antenna should stand mostly upright and the navigation anshytenna should be mostly sideways

But you say when I practice steep turns or fly knife edge cross-country I sti ll receive both communication and navigation signa ls Good point - but nothing in this discussion of antenna wizardry is absolute Like the ripples on the water the waves are there and if we re within range well receive them sometimes strong sometimes weak

FAIRCHILD 24R PROJECT

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

VINTAGE AIRPLANE 13

An investigation revealed the Rangershypowered Fairchild which was registered in Argentina as LV-AFH has about 1900 hours total time on the airframe and had last been used to haul parachute jumpers in the late 1960s Roy hopes to restore the airplane to flying condition and possibly fly it to EAA Oshkosh 95 (his 40th birthday) We wish Roy and his crew the very best as they restore this beautiful cabin Fairchi ld to flying condishytion

Carefully placed on a flatbed truck the fuselage and engine complete w ith cowling are ready for transport to the seaport in Buenos Aires where the entire Fairchild was fitted into a 20-foot container for shipment to California We look forward to seeing Roy and his jewel at Oshkosh

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Tom Mangans Aeronca Champion 7CCM

N2182E SIN

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

Charles Sylvias Cessna 1708

The photos of this very nice 1955 Cessna 170B N3590C SIN 26634 were sent in by owner Charles Sylvia (EAA 446109 A IC 21377) of Middleboro MA Charles and his wife Connie have been extremely busy upgrading the four-placer to full IFR certification since purchasing the 170 in June of 1993 Powered with a Continental 0shy300 engine of 145 hp swinging a McshyCauley polished propeller the 170 has had a new paint job on the outside and a new interior inside Other amenities include new engine baffling Jasco 50

The photo of this 1947 Cessna 140 N2084V SIN 14300 with its Gee Bee inspired paint scheme was sent in by owner Don Alesi (EAA 371460 AIC 16315) of Dundee IL Don reshyports the Cessna was restored over a period of eight months by his wife Maureen his brother Bob Alesi and himself The 140 was painted with the Superflite System II from Cooper usshying Juneau White and Rasberry Red The color scheme was devised to make the airplane highly visible - and look fast while standing still Fienshyfield Aviation of Lake-In-The-Hills Airport helped with rigging and final assembly The first flight was May 10 1994 and it flew hands off This airshyplane was on line at Spring City

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

The Great Depression cut into the production of the Coach and unfortushynately not too many were built A few had the 225 hp Wright J-6-7 The proof that the ship in your picture is powered by a J -5 - the (once) world famous 220 hp Wright Whirlwind first made popushylar by Lindbergh in his Spirit of St Louis - the proof is the pair of clearly

FAIRCHILD 24R PROJECT

(Above) At some time in the past a reshyally competent metal worker made a replica exhaust manifold for the Ranger engine Roy says the rust is only supershyficial and should clean up nicely

(Left) Thats a semi-smiling Roy Trilla on the right with his hand on the wooden prop with his uncle on the left The reashyson for the smirk is the thought of all the $$ that will be needed to get the old girl flying again Note the unusual tread on the main tires that almost have an imshyplement look to them

A high tech engine crane was made to lift the big Ranger 440 cu in engine from the fuselage Thats Roys uncle on the come-along and Richard Macaferty guiding the engine from the firewall with the end of the crankshaft

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

VINTAGE AIRPLANE 13

An investigation revealed the Rangershypowered Fairchild which was registered in Argentina as LV-AFH has about 1900 hours total time on the airframe and had last been used to haul parachute jumpers in the late 1960s Roy hopes to restore the airplane to flying condition and possibly fly it to EAA Oshkosh 95 (his 40th birthday) We wish Roy and his crew the very best as they restore this beautiful cabin Fairchi ld to flying condishytion

Carefully placed on a flatbed truck the fuselage and engine complete w ith cowling are ready for transport to the seaport in Buenos Aires where the entire Fairchild was fitted into a 20-foot container for shipment to California We look forward to seeing Roy and his jewel at Oshkosh

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Tom Mangans Aeronca Champion 7CCM

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

coach was a 1928 designed 4-place ship built by the Mono Aircraft Co Moline IL far better known for their famous and popular Monocoupe

The Great Depression cut into the production of the Coach and unfortushynately not too many were built A few had the 225 hp Wright J-6-7 The proof that the ship in your picture is powered by a J -5 - the (once) world famous 220 hp Wright Whirlwind first made popushylar by Lindbergh in his Spirit of St Louis - the proof is the pair of clearly

seen front-mounted Scintilla mags a stand-off recognition feature of all J-5s I suspect the NACA cowling was a later addition Before the war I flew quite a few J-5s

Lennart Johnson Eldsberga Sweden adds this

The specimen in the picture NC 8953 was the third Model 201 built It was owned in 1932 by R A Purcell 1315 S Union Av Alliance Ohio and in 1936 by W P Barnum Crandal Av Youngstown Ohio

FAIRCHILD 24R PROJECT

(Above) At some time in the past a reshyally competent metal worker made a replica exhaust manifold for the Ranger engine Roy says the rust is only supershyficial and should clean up nicely

(Left) Thats a semi-smiling Roy Trilla on the right with his hand on the wooden prop with his uncle on the left The reashyson for the smirk is the thought of all the $$ that will be needed to get the old girl flying again Note the unusual tread on the main tires that almost have an imshyplement look to them

A high tech engine crane was made to lift the big Ranger 440 cu in engine from the fuselage Thats Roys uncle on the come-along and Richard Macaferty guiding the engine from the firewall with the end of the crankshaft

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

VINTAGE AIRPLANE 13

An investigation revealed the Rangershypowered Fairchild which was registered in Argentina as LV-AFH has about 1900 hours total time on the airframe and had last been used to haul parachute jumpers in the late 1960s Roy hopes to restore the airplane to flying condition and possibly fly it to EAA Oshkosh 95 (his 40th birthday) We wish Roy and his crew the very best as they restore this beautiful cabin Fairchi ld to flying condishytion

(Left) With a platform to fasten the engine to the Ranger is tipped to the vertical complete with oil tank and engine mount and readied for shipping to the U S That s Richard Macaferty smiling at the accomplishment Note the round oil cooler with its atshytendant air inlet from the nosecowl and exhaust on the righthand side of the engine cowling

Carefully placed on a flatbed truck the fuselage and engine complete w ith cowling are ready for transport to the seaport in Buenos Aires where the entire Fairchild was fitted into a 20-foot container for shipment to California We look forward to seeing Roy and his jewel at Oshkosh

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

FAIRCHILD 24R PROJECT

Some folks live right EAA member Roy Trilla (EAA 422597 AC 19955) of Berkeley CA bought a Fairchild 24R way down in Argentina sight unseen with the help of his uncle The uncle flew the Fairchild to his farm where it was tied down outside for most of two years In April of 1994 Roy made the long trip to Azul Argentina about 150 miles southsouthwest of Buenos Aires to arrange for disassembly and crati ng of the airplane for shipment back to California

VINTAGE AIRPLANE 13

An investigation revealed the Rangershypowered Fairchild which was registered in Argentina as LV-AFH has about 1900 hours total time on the airframe and had last been used to haul parachute jumpers in the late 1960s Roy hopes to restore the airplane to flying condition and possibly fly it to EAA Oshkosh 95 (his 40th birthday) We wish Roy and his crew the very best as they restore this beautiful cabin Fairchi ld to flying condishytion

Carefully placed on a flatbed truck the fuselage and engine complete w ith cowling are ready for transport to the seaport in Buenos Aires where the entire Fairchild was fitted into a 20-foot container for shipment to California We look forward to seeing Roy and his jewel at Oshkosh

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

VINTAGE AIRPLANE 15

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Tom Mangans Aeronca Champion 7CCM

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

The corrugated ailerons on the UBF-2 wings are beautifully crafted out of aluminum The UBF-2 was the first Waco airplane to feature ailerons made completely out of metal

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

Charles Sylvias Cessna 1708

The photos of this very nice 1955 Cessna 170B N3590C SIN 26634 were sent in by owner Charles Sylvia (EAA 446109 A IC 21377) of Middleboro MA Charles and his wife Connie have been extremely busy upgrading the four-placer to full IFR certification since purchasing the 170 in June of 1993 Powered with a Continental 0shy300 engine of 145 hp swinging a McshyCauley polished propeller the 170 has had a new paint job on the outside and a new interior inside Other amenities include new engine baffling Jasco 50

The photo of this 1947 Cessna 140 N2084V SIN 14300 with its Gee Bee inspired paint scheme was sent in by owner Don Alesi (EAA 371460 AIC 16315) of Dundee IL Don reshyports the Cessna was restored over a period of eight months by his wife Maureen his brother Bob Alesi and himself The 140 was painted with the Superflite System II from Cooper usshying Juneau White and Rasberry Red The color scheme was devised to make the airplane highly visible - and look fast while standing still Fienshyfield Aviation of Lake-In-The-Hills Airport helped with rigging and final assembly The first flight was May 10 1994 and it flew hands off This airshyplane was on line at Spring City

Unique to this 170 is a set of the origishynal Goodyear brakes and wheels that have the Goodyear crosswind landing gear installed allowing the airplane to land in a crab For new passengers who have never experienced landing sideways it is indeed an elevation of the pucker factor Next on Charlies want-list are a Vernier mixture conshytrol heated pitot and a Whelen double flash beacon on the belly

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

l y Wng nd Roy Rdm of Minshynesota have combined talents to put toshygether one of the prettiest Waco UBF-2s seen in recent years It had been a long time since NC13027 had seen any use shysince 1946 in fact But Jerrys desire and capability to own a rare open cockpit bishyplane coupled with the extraordinary talshyents of Roy Redman and his crew at Roys Aircraft Service in Faribault MN reshysulted in an all out effort to put a real basshyketcase back together again

Finished at the Waco factory in Troy OH on June 29 1932 Waco UBF-2 NC13027 was delivered to Joe Cannon Jr of Charlotte NC A few years later it wound up in the Midwest and after the war in 1946 a fellow named Archie Towle had an unfortunate and fatal accident with this particular F-2 in the Wausau WI area Years later the Towle family gave the remains of the airplane to John Hatz of Gleason WI John had intended to keep the airplane as a project he could work on after he retired but as many AIC members will recall John lost his li fe in a truck accident in 1989 Forrest Lovely and Roy Redman both knew John and were aware of the projects and bits and pieces that John had gathered over the years and so when the Hatz family let it be known they were interested in selling Johns projects the timing would be right for another set of circumstances to come together

Another friend of Roys Gary Undershyland a well-known restorer and mechanic for Buzz Kaplan introduced Jerry to Roy and Forrest After some preliminary disshycussions Roy and Jerry put a program toshygether that allowed Jerry to buy the Waco project and Roy to restore the airplane The project was begun in early 1992 and there was a lot to be accomplished

John Hatz had begun the process of reshypairing the bent fuselage and thats where Roy got started Using factory blueprints as he did durin g th e restoration and reshyconstruction of many of the parts and pieces needed Roy built up the fuselage for th e Waco a nd the n star ted on the wings Tom Flock did the work on reshyskinning the ailerons which were in rough shape The Waco UBF-2 was the first airshyplane built by Waco with aluminum ailerons and the workmanship by Tom a well-known Waco restorer is exemplary The love these Waco aficionados have for the aircraft is evident in the workmanship shown in each of the parts they work on

The wings presented another challenge to the capable ha nd s of Ro y Redm an Armed with a full se t of Waco blueprint copies collected from various other hobshybyists and the Smithsonian Air and Space

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

The corrugated ailerons on the UBF-2 wings are beautifully crafted out of aluminum The UBF-2 was the first Waco airplane to feature ailerons made completely out of metal

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

The photo of this 1947 Cessna 140 N2084V SIN 14300 with its Gee Bee inspired paint scheme was sent in by owner Don Alesi (EAA 371460 AIC 16315) of Dundee IL Don reshyports the Cessna was restored over a period of eight months by his wife Maureen his brother Bob Alesi and himself The 140 was painted with the Superflite System II from Cooper usshying Juneau White and Rasberry Red The color scheme was devised to make the airplane highly visible - and look fast while standing still Fienshyfield Aviation of Lake-In-The-Hills Airport helped with rigging and final assembly The first flight was May 10 1994 and it flew hands off This airshyplane was on line at Spring City

amp alternator El Reno spin-on oil filshyter new instruments and complete new wiring harness using circuit breakers instead of fuses A Precise Flight standby vacuum system augments the venturi system All avionics were upshygraded to IFR standards and include a Garmin 95AVD GPS which Charlie says is the answer to a navigator s prayers It uses an outside antenna which helps with the cabin clutter

Unique to this 170 is a set of the origishynal Goodyear brakes and wheels that have the Goodyear crosswind landing gear installed allowing the airplane to land in a crab For new passengers who have never experienced landing sideways it is indeed an elevation of the pucker factor Next on Charlies want-list are a Vernier mixture conshytrol heated pitot and a Whelen double flash beacon on the belly

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Museums collection he dove into the process of rebuilding a very rough set of wing panels most of which were only good for patterns The wing center secshytion was also rebuilt along with a pair of 20 gallon fuel tanks Jerry Brown yet anshyother well known and talented Waco reshystorer was able to come up with a couple of neatly machined acrylic fuel gauge blanks that Roy could use to rebuild the fuel gauges Here s an interesting sideshylight to the fuel gauge restoration For years I wondered what type of paint had been used to highlight the fuel gauge markings that were completely immersed in gasoline On the Waco you can see the red indicator made out of cork is painted bright red and on many other gauges black markings are made on a soft aluminum faceplate riveted to a rotating drum When I asked Roy what type of paint he has been using all these years to color the indicator he answer seemed both obvious and surprising all at the same time - butyrate dope Plain old straight-from-the-can butyrate dope which as Roy points out has been fuel proof for years and years with hardly any deterioration noticed over time The cork at the other end of the wire floating on the top of the fuel is coated with plain old shellac

The center section also has the densest wood you can find on the aircraft - the stiffeners on the bottom of the fuel tank section are made of oak and are varshynished to a high gloss Also mounted inshy

conspicuously on the top of the wing censhyter section is a GPS antenna since Jerry planned on flying the airplane cross-counshytryon a regular basis

The cockpits were another area that alshylowed Roy to show his restoration prowess Sometimes restoring an airshyplane means knowing when to send someshything out to an expert and Roy certainly understands that point The instrumentashytion a full set of period instruments was sent out to Philip Kraus Vintage Aero in Westport NY one of the foremost authorshy

ities on antique instrument repair Roy points out that it pays to be patient since the demand for Phillips services is great and he therefore always has some backshylog The restoration takes time as well with time often needed between steps durshying the rebuilding process It pays to preshyplan the instrument panel at the beginning of the project rather than waiting until the end of the airplanes restoration

The panel itself was constructed using factory blueprints As you can see in the accompanying photos Waco went to the trouble of mounting all of the instruments from the back of the panel so that none of the screw heads would be showing and Roy followed the factory plans to the letshyter A neat panel overlay made out of alushyminum is also added to the panel and it is set into an 6463 extrusion that Roy had to have specially made per the factory blueshyprints To get the aluminum extrusion Roy had to have a set of dies machined and then take to dies to an aluminum foundry where an entire production run of the special shape had to be run Roy had to buy the entire run so if you need a section of this extrusion give him a call at 507334-5756 - he says he would be happy to sell you what you need cause he has plenty

Around each of the instruments is an aluminum bezel to professionally finish off the panel just as it was done at the facshytory in 1932 Black crinkle finish enamel is used for both the front and aft cockpit panels The forward panel has two well

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

The corrugated ailerons on the UBF-2 wings are beautifully crafted out of aluminum The UBF-2 was the first Waco airplane to feature ailerons made completely out of metal

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

Unique to this 170 is a set of the origishynal Goodyear brakes and wheels that have the Goodyear crosswind landing gear installed allowing the airplane to land in a crab For new passengers who have never experienced landing sideways it is indeed an elevation of the pucker factor Next on Charlies want-list are a Vernier mixture conshytrol heated pitot and a Whelen double flash beacon on the belly

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

executed glove boxes complete with origshyinal style latches The latches come from an obvious but often ignored source shythey re made from cabinet latches They re the type of spring-loaded latch used on the inside of a double-doored cabinet used to hold the one door closed while the other door is opened with a knob or handle With a little modification to put the correct shape handle on the end of the latch they were ready to go and look and function just like the original latch It turns out that the latch used by Roy and supplied to him by a cabinet maker friend who also does some woodshyworking for some of Roy s restorations has been in production since the 1930s and may very well be the same basic style used by Waco during the original producshytion of the airplanes

All of the sheet metal edges on the glove box doors were finished as per the original including the beading of the perimeter of the doors Intended to add some stiffness to the doors and the sheet metal panels on the exterior of the airshyplane they also added a touch of class and gave the panels a finished profession al look Waco was world renowned for their attention to detail and workmanship and Roy and his crew have tried to keep that in mind as they work on all of the planes theyve restored

There are a couple of interesting points about the color scheme of the Waco bishyplanes something that showed how Clayshyton Bruckner and his craftsman paid atshytention to each and every aspect of Waco production The colors on most factory finished Wacos had color on the fuselage only - recall the pictures of Wacos youve seen over the years Most had silver wings and horizontal tail surfaces with color confined to the fuselage and vertical fin and rudder The effect as pointed out by both Roy and Jerry is to draw the eye of the beholder to the fuselage Roy menshytioned that he was told by one of the oldshytimers from the Waco factory that they were emulating the automobile inshy

dustry in a lot of ways They tried to make these things look like cars They painted the fuselage put the color on the fuselage fin and rudder The rest of the airplane was painted black lacquer (struts landing gear etc) or si lver They also painted the screw heads (You never saw old cars with shiny screw heads )

This particular UBF-2 was delivered with a black and white scheme Jerry thought about that for some time before he decided he just couldnt put black and white on his airplane He want to mainshytain the actual art layout but it would just have to be in other colors He went porshying through the color books and decided on the two-tone blue scheme you see on these pages

The engine did not come with the proshyject but one was obtained that is the corshyrect make and model - a Continental R670 of210 hp Jack Lanning of Arlington W A and a well-known Travel Air restorer did the overhaul and shipped the engine to Roys Aircraft A needed Hamilton Standard Ground Adjustable prop was alshyready on the shelf at Roys - he had bought it a number of years before and loaned it to Jerry for use on the Waco for the certishyfication and the airplanes first flights Since that time a Curtiss Reed prop also

correct for this airplane has been inshystalled

Jerry Wengers involvement in the Waco project started much earlier in his life it just took a number of years before the desire could be satisfied The son of a successful manufacturer of music room equipment and interiors Jerry chose a difshyferent path He learned to fly for free by standing out in a pea fie ld (or whatever else needed spraying) with a red flag and guiding a cropduster making spray passes In return he received flight instruction His uncles and grandfather were both pishylots but Jerrys father who always wanted to learn never got around to getting in the cockpit as a student but he did encourage his son Jerry headed off to college after getting his pilots license but he discovshyered that engineering academics were not his strong suit at that point in his life In a J-4 Cub he had rebuilt he headed out to South Dakota looking for more work After spending time with Dan Wakefield in North Dakota flight instructing and other flying duties he went to Winter South Dakota and sprayed crops with Bob Wiley It was the late 1950s and the milishytary began to show an interes t in young men about that time Fortunately a young lady also bega n to show an even greater

(Above) The forward cockpit for the passengers has a pair of gloveboxes that are just right for keeping gloves maps and your helmet and goggles Theyre also handy for keeping your hands warm since the heat from the engine oil keeps the air heated in that area An intercom visible on the lower right makes cockpit communication possible

(Left) The wooden stiffeners for the bottom of the fuel tank bay in the wing center section along with the pair of visual fuel gauges on each of the fuel tanks

(Opposite page) With a steerable non-swivel tailshywheel the rudder is free to get banged around in the wind but Roy built this nifty rudder lock As you can see it straddles the trailing edge of the rudder and is attached to the tail brace wires by a couple of lengths of cord secured with a half hitch or two

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

The corrugated ailerons on the UBF-2 wings are beautifully crafted out of aluminum The UBF-2 was the first Waco airplane to feature ailerons made completely out of metal

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

amount of interest in Jerry and he wound up getting married

Soon he was blessed with a little Wenger to support as well so he took a job building log cabins up in the northern tier of states One cold January morning in 1960 the man Jerry was working for anshynounced that he would see Jerry and the rest of the fellow in the spring - no more work until April or May With a wife and child to support Jerry gave his dad a call

His dad gave Jerry a job in his manushyfacturing business Jerry was pleasantly surprised to find he enjoyed the business and found that he even had a talent for many of the aspects of inventing and putting into production the items he and his dad s company built He finished a business degree in college and later headed up the product design department for the company Inventing was fun as was the process of figuring out how to produce the part To this day Id rather design products than play golf he reshycently quipped

Other businesses grew out of his work

with Wenger Manufacturing including running the Owatonna MN airport an outgrowth of the company flight departshyment Other aviation service related busishynesses came along and have since been sold as Jerry consolidates his resources

During all this time aviation was never far from his thoughts The company flight department consisted of a series of airshycraft including a Beech King Air and later Jerry bought a Cessna P210 to carry him to his various business appointments For fun and a sense of sport he now also flies a Nimbus 3DM motorglider which he bases in Colorado He really enjoys the gentle sport of soaring and as time went on he also found himself drawn to the F-2 flown by Woody Woods son Chris He was intrigued by the idea of an antique open cockpit biplane so he did some research and decided that the F-2 was indeed the airplane to own - as far as he was concerned it was the pinnacle of Waco s open cockpit series of biplanes The more people he talked to the more he was convinced and his path eventually

led him to Gary Underland who introshyduced him to Roy and Forrest

After the ai rplane was finished Roy and Jerry flew the airplane on a ferry pershymit to Arkansas where they did a little work on it at Jim Younkins shop as well as have the conformity inspection by the FAAs Little Rock GADO office Then it was on to Sun n Fun where it won the Silver Age (1928-1932) trophy Roy then turned over the reins to Jerry and both were happy to see that Jerry hadnt lost any of his touch with a tailwheel-equipped airplane - it was like magic the guy took off landed it we went around again he landed and I thought For Gods sakes he doesnt need me recalled Roy about the first time he sat in the front cockpit with Jerry as pilot-in-command

It s now been to Oklahoma for the NBA fly-in where it was given the Open Biplane Grand Champion award and it also was flown by Jerry and his wife down to the National Waco Associations shindig at Creve Coeur MO Hes enjoyshying the cross-country capability of the UBF-2 flying at a 1000 feet agl enjoying the view at 100 mph How much does he like it

Hes seriously thinking of selling the P210 - after all he says who needs all that hassle of IFR time when you can get where you want to go in the F-2 For him the challenge of flying IFR has since been replaced with the joy of YFR flight with an antique biplane going where he wants to go at a leisurely pace He must enjoy it - he figures to have nearly 100 hours on the plane by the end of the summer flying season

Maybe I should take it down south and fly it this winter he mused during our conversation Thats the spirit Jerry

Tom Mangans Aeronca Champion 7CCM

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Tom Mangans Aeronca Champion 7CCM

N2182E SIN

It is always nice to have a pretty Aeronca 7CCM Champ on skis after we have presented the same airplane on floats This photo proves that Tom Mangan (EAA 297907) of Brewerton NY also flies his Champ in the winter time Note the seaplane door in the raised position Mounted on Federal A-1500 skis the Champ does a fine job in the cold winter air according to Tom and the dual exhaust (with heat muffs) makes for a warm cabin

Don Hedemans Pietenpol Aircamper

This photo of a restored 1932 Pietenpol Aircamper NI2072 SIN Bshy2 was sent in by the original builder (and veteran pilot) Harold Salut (EAA 92575 A C 1772) of Bemidji Minnesota The cute little parasol was restored by Don Hedeman (EAA 57678 AC 4585) of Dubuque Iowa The Pietenpol was constructed in 1931shy32 in Fargo NO by Harold Salut and a man named G Bebeau and was powshyered with a Ford Model A engine Harold who admits to 78 years says he flipped the airplane on its back on June 3 1933 while landing in a bunch of fresh cow pies in a pasture The remains were sold for junk however many years later it was re-discovshy

ered in 1985 Don reports the Model A engine runs fine and they hope to try out the flying characteristics as soon as they put the original registration numshy

ber of N120n on the tail Present plans call for the Pietenpol to eventushyally be placed in a museum in Fargo NO

Jay Martins Meyers 200A

This pretty 1959 Meyers 200A N485C SIN 253 is the pride and joy of Jay Martin (EAA 357519) of Thousand Oaks CA Jay spotted the Meyers sitshyting quietly under the wing of a DC-3 at Van Nuys airport It was derelict and in need of a great deal of help After much

dickering the Meyers was finally purshychased in October of 1988 For the next two months all the crew did was take things apart The next nine months were spent buying bearings skin wiring and parts of all kinds including radios instruments etc Two and a half years

later the Meyers is starting to look like a winner and Jays mechanic Larry Clark is still improving things one at a time As you will note from the picture the Meyers is a very sharp looking airplane and Jay reports it makes an excellent cross-country machine

Sharp-eyed readers (with a tad of grey hair) may recognize this Meyers 200A as the being the very same airshyplane N485C that Peter Gluckmann (the flying watchmaker) flew 22800 miles around the world in August and September of 1959 starting and ending in San Francisco CA Using a wet wing that upped the total fuel to 400 galshylons Peter was able to circumnavigate the earth in just over 13 days - all under F AI supervision and sanction Takeoff weights were often 5000 lbs 2000 lbs over normal gross The full story was printed in the February and March 1960 issues of AIR FACTS magazine

Charles Sylvias Cessna 1708

The photos of this very nice 1955 Cessna 170B N3590C SIN 26634 were sent in by owner Charles Sylvia (EAA 446109 A IC 21377) of Middleboro MA Charles and his wife Connie have been extremely busy upgrading the four-placer to full IFR certification since purchasing the 170 in June of 1993 Powered with a Continental 0shy300 engine of 145 hp swinging a McshyCauley polished propeller the 170 has had a new paint job on the outside and a new interior inside Other amenities include new engine baffling Jasco 50

The photo of this 1947 Cessna 140 N2084V SIN 14300 with its Gee Bee inspired paint scheme was sent in by owner Don Alesi (EAA 371460 AIC 16315) of Dundee IL Don reshyports the Cessna was restored over a period of eight months by his wife Maureen his brother Bob Alesi and himself The 140 was painted with the Superflite System II from Cooper usshying Juneau White and Rasberry Red The color scheme was devised to make the airplane highly visible - and look fast while standing still Fienshyfield Aviation of Lake-In-The-Hills Airport helped with rigging and final assembly The first flight was May 10 1994 and it flew hands off This airshyplane was on line at Spring City

amp alternator El Reno spin-on oil filshyter new instruments and complete new wiring harness using circuit breakers instead of fuses A Precise Flight standby vacuum system augments the venturi system All avionics were upshygraded to IFR standards and include a Garmin 95AVD GPS which Charlie says is the answer to a navigator s prayers It uses an outside antenna which helps with the cabin clutter

Unique to this 170 is a set of the origishynal Goodyear brakes and wheels that have the Goodyear crosswind landing gear installed allowing the airplane to land in a crab For new passengers who have never experienced landing sideways it is indeed an elevation of the pucker factor Next on Charlies want-list are a Vernier mixture conshytrol heated pitot and a Whelen double flash beacon on the belly

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

cooler the blast of air past the case and the All the conveniences of home Sandy and Phil Mc Kenzie of Chapter 797 in Live Oak exposed parts carry off the excess heat In Florida put together this little display at EAA Sun n Fun 94 Makes you wonder how some of the engines the inta ke tubes a re many of their fellow campers asked to use the facilities

Charles Sylvias Cessna 1708

The photos of this very nice 1955 Cessna 170B N3590C SIN 26634 were sent in by owner Charles Sylvia (EAA 446109 A IC 21377) of Middleboro MA Charles and his wife Connie have been extremely busy upgrading the four-placer to full IFR certification since purchasing the 170 in June of 1993 Powered with a Continental 0shy300 engine of 145 hp swinging a McshyCauley polished propeller the 170 has had a new paint job on the outside and a new interior inside Other amenities include new engine baffling Jasco 50

The photo of this 1947 Cessna 140 N2084V SIN 14300 with its Gee Bee inspired paint scheme was sent in by owner Don Alesi (EAA 371460 AIC 16315) of Dundee IL Don reshyports the Cessna was restored over a period of eight months by his wife Maureen his brother Bob Alesi and himself The 140 was painted with the Superflite System II from Cooper usshying Juneau White and Rasberry Red The color scheme was devised to make the airplane highly visible - and look fast while standing still Fienshyfield Aviation of Lake-In-The-Hills Airport helped with rigging and final assembly The first flight was May 10 1994 and it flew hands off This airshyplane was on line at Spring City

amp alternator El Reno spin-on oil filshyter new instruments and complete new wiring harness using circuit breakers instead of fuses A Precise Flight standby vacuum system augments the venturi system All avionics were upshygraded to IFR standards and include a Garmin 95AVD GPS which Charlie says is the answer to a navigator s prayers It uses an outside antenna which helps with the cabin clutter

Unique to this 170 is a set of the origishynal Goodyear brakes and wheels that have the Goodyear crosswind landing gear installed allowing the airplane to land in a crab For new passengers who have never experienced landing sideways it is indeed an elevation of the pucker factor Next on Charlies want-list are a Vernier mixture conshytrol heated pitot and a Whelen double flash beacon on the belly

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

ARE YOU

LEGAL

by Bill Claxon Ale 17837

0 hould [y h yo pl legal As we fly these aircraft espeshycially the older antiques and classics they seem to accumulate changes and repairs as well as different appliances and equipment But are all of these truly legal

Many owners are of the opinion that if the Authorized Inspector (AI) signs the log bOok certifying an annual inshyspection that all the work done is legal It would seem that this is how it should be but it depends upon how deeply the AI digs into the airplane and the mainshytenance records Often a thorough search will disclose discrepancies beshytween what should be and what actually is In some cases you may find that something has been installed or a repair made and no entry in the maintenance records or Form 337 available or filed Perhaps an Airworthiness Directive (AD) not properly complied with or enshytered As the airplanes get older they are more apt to have more of these disshycrepancies I know of aircraft that have entries in the maintenance records statshying See ACA 337 dated this day conshycerning major repairs or alterations but the 337s are not with the records and they are not on file with the FAA It is evident that all 337s do not get filed as required by the regulations

Why do these discrepancies exist There may be several reasons Records can be lost or destroyed or oversights by the mechanic or AI during the repair or inspection can occur although fortushynately that is a rare occurrence Records are sometimes lost to loose time or a major repair on an airplane Anyone doing so is looking at the poshytential for a hefty fine andor certificate action by the FAA but it has happened Sometimes the maintenance records are honestly lost or misplaced Howshyever a trace of the 337s and repair stashytion maintenance releases may reveal authorizations for some of the past reshypairs or alterations not shown in the current maintenance records

Tracing all repairs alterations instalshylations and appliances can be a long and expensive task if done by a maintenance facility The paper trail on some of these older airplanes has become quite long You as the owneroperator can do a lot of the paper trace prior to the annual and save yourself much of the

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

That s this month s installment What do you have to add to our growing list of useful tidbits Remember we re adding new folks to our ranks every day and to help them along as they become more familiar with their airplanes we can all do our part and teach them what we alshyready know Let s pass it along Send you A C Tidbits to HG Frautschy EAA Aviation Center PO Box 3086 Oshkosh WI 54903-3086

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

You as the owneroperator can do a lot of the paper trace saving yourself much of the expense involved

in having this tedious job done by your AI during your annual inspection

expense and labor costs of this tedious job This is especially true if you have a good rapport with the inspecting agency and are doing an owner assisted annual

Why does this need to be done The airplane is flying well as it is Perhaps only to be legal I have talked with sevshye ral insurance underwrit e rs and the general consensus is that if the discrepshyancy does not enter into the cause of the accident there is no problem If the disshycrepancy is the cause or partial cause of an accident then it may be used to deny full or partial payment of the claim One well known underwriter said that if the discrepancy was in existence at the time of the last annual and the annual was signed off as airworthy it would pay the claim If the discrepancy came into existence subsequent to the last anshynual they would not pay the claim Some companies will not pay the claim if any discrepancy exists However if the airplane is not legal if could lead to litigation that could cost you time and money And that is not taking into conshysideration the views of the FAA and their stand on such matters

So where do we start First obtain a copy of the Type Certificate Data Sheet and Specifications for your particular airplane Any IA has these available and may let you copy the pages Often they are available from the manufacshyturer or current holder of the type cershytificate The specifications will give you a listing of the required and optional eq uipment engines propellers and other appliances as approved under the type certificate It also has data for the aircraft such as datum gross weight center of gravity and loading limits air speed limits engine operating limits placards required and other data

Microfiche copies of your airplanes records are available from the DOT They are identified by your registration number so if you changed the number you need to advise them of that fact while making your request The records may be obtained by writing the DOTFAA Aircraft Reg Branch PO Box 25504 Oklahoma City OK 73125 For faster service you can order by phone 405954-3116 The cost is $200 for the search and fifteen cents for each microfiche This will give you a comshy

337s filed with the FAA and other mainshytenance data right on up to the latest owner liens etc If your airplane is older than about 1956 additional inforshymation is available Until about that time each aircraft required an applicashytion for a new airworthiness certificate each year

This required two forms ACA 305 Application for Airworthiness Certifishycate andor Annual Inspection of an Aircraft and ACA 305A Aircraft Inshyspection Report Among other things these reports give the total time as of that date AD compliance engine inshystallation and time as well as other inshyformation It is well worth the cost of about $250 per airplane This could be invaluable information if you are conshytemplating the purchase of an older airshyplane especially if some of the data preshysented is lacking or suspect A copy of all the service bulletins and letters of the aircraft and engine could be very helpshyful

If an item is not listed in the specifishycations there needs to be other apshyproval data for the particular equipshyment This may be in the form of a Form ACA 337 a supplemental type certificate a release from a repair stashytion or other agency

The original equipment listing for the airplane as it came from the factory is a good starting place to determine if all items installed are approved This will give a listing by number corresponding to a number for each item listed in the type certificate of items installed at the time the airplane left the factory along with the original weight and balance sheet From there on all items added or removed should be shown in the approshypriate maintenance records and on a Form 337 or maintenance release Also you must have a current weight and balshyance sheet

Armed with this data you are ready to start the actual inspection of the airshyplane You can remove all the inspecshytion plates and cowlings so long as you do not have to disconnect controls or reshymove the prop as detailed in Part 43 of the regulations unless you are working under the supervision of a licensed meshychanic Start at one end of the airplane and look at each item and repair See if

Then see if it has been properly listed and approved For instance look at the propeller make and model to determine if it is an approved prop for your model airplane Then look at the specificashytions to determine if it is within the length specifications Measure the prop from tip to tip to see if it does in fact meet the minimum length requirement as props are sometimes shortened durshying repa irs On run-up see if it meets static RPM specifications

Any items not shown should be inshyspected to determin e that it is an apshyproved part Approval data may be in the specs STC number TSO number locally approved or other data Check the item for airworthiness and for proper installation It may then be reshyleased on a properly executed Form ACA 337 by stating that the item was found previously installed and is in airshyworthy condition Major repairs or alshyterations may be released in the same manner if they are not shown in the maintenance records and the 337 has not been filed

Also look at the engine and accesshysories to see if the proper model correct mags carb starter etc as those listed in the engine specifications Another item that needs to be reviewed is the Airworshythiness Directives and service bulletins We will go through these at a later date

While you do this inspection it is a good time to completely clean the airshyplane and do some of the routine mainshytenance as approved by Part 43 of the regulations Also take a good look at anything that may need attention such as the start of corrosion rust wear or anything else before it becomes a costly problem Remember if you do not hold a mechanics certificate you cannot do any maintenance that is not included in part 43 - only your mechanic is authoshyrized to do that work

This will help you get a quick ecoshynomical annual inspection It will also enhance the value of your airplane give you better insight into its operation and perhaps save you some problems later on Happy flying

Next month Bill Claxon will cover the pete history of your airplane starting the item or appliance is an approved world of Airworth iness Directives in with the test flight and the first owner unit by model number or other data AD Notes and You 22 SEPTEMBER 1994

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

Ale TidbiTs

by HG Frautschy

A few of you have responded to my reshyquest to send little tidbits of technical inshyformation tha t could be of use to many others Among th e first was Chuck Burtch EAA 56205 an EAA designee and all around good guy as he also helps out the EAA Aviation Foundation as an instructor each summer during the EAA Air Academy prior to the EAA Convenshytion

For those of us in the upper half of the northern hemisphere the cold weather is but a few short weeks away Chuck found that while flying in the winter it was tough to get the oil temperature up to an acceptshyable level He knew that blocking some of the airflow over the engi ne would help boost the temperatures back up to acceptshyable levels but he was leery of overheatshying the cylinder heads (these covers only block a ir over the lower section of the cylinders) With them he was able to get oil temps back up to around 180degF Heres a few sketches of his inlet covers - with a bit of ingenuity Im sure you can come up with something that can cover your needs Remember keep that cooling air flowing over those aluminum cylinder heads

A seemingly endless source of subshyjects for mechanical repairs is the landshying gear of our airplanes In the accomshypanying photo you can see the results of too much taxiing on struts that had little or no oil left in them - a broken coil spring This particular landing gear on my llCC Super Chief was suspect when I bought the airplane When you looked at the airplane from the front it had a definite lean to one side and more strut was exposed on the opposite side When the drain plug was removed from the bottom of the strut a small amount of gunky thick red hydraulic fluid oozed out Since this type of gear relies on the hydraulic fluid to dampen the shock of landings lessening the hammering effect on the spring I imshymediately suspected that the spring was broken and after removing the gear and pulling the strut out of the housing I was greeted with the sight you see here - a fractured spring Suspecting the other side was probably serviced the same way I ordered two springs and took a good look at the rest of the strut On the top of the cylinder is a graphite impregnated rope packing similar to the packing used in automotive applicashytions for a rear crankshaft seal It keeps the fluid in the strut during the up and down action of shock absorbing but if it becomes worn fluid is pumped out of the strut and the spring no longer has anything to help cushion landing loads If you have a similar type of non-presshysurized strut be sure to inspect and sershyvice the strut on a regular basis I know

it s a bit of a pain to do - you have to put the airplane on some sort of jack and raise the gear to the point the drain hole is higher than the other end

Ive found that a 1 pint polyethylene bottle with a sealed (non-vented) top and a supply tube extending all the way to the bottom works best to fill the strut The one I use was bought at a surplus science supply house and was intended to hold alcohol for cleaning or irrigating purposes When you squeeze the botshytle fluid is pushed up the supply tube and out the nozzle It looks something like this

It s very handy and less messy than a bottle and a funnel Try Edmund Scienshytific or similar outfits for a similar botshytle Medical supply houses probably also would carry something similar

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

Engine mounts also suffer from neshyglect and if you happen to have a spinner that tracks near your cowl you can hear some expensive rubbing noises if the rubshyber mount deforms too much Manya Chief nose bowl has been damaged by the spinner rubbing against the cowl Believe it or not the mount you see in this shot was only 2 years old when it was replaced The small necked-down area has been exshytruded out through the front of the engine mount and you can also see that it has deshyformed so that the engine droops downshyward at rest The quality of the rubber for these mounts (this one happens to be from a Continental but the source of the mounts is unknown) seems to vary widely Some have been rather hard while others seemed to be a bit on the soft side I d recommend having a spare set or two on hand at all times and removing and inshyspecting them each annual Besides they re cheap as well - a full set of eight can be had for less than $1500 If you noshytice that your spinner or prop hub just doesnt seem to line up the way they used to it may not be the cowl thats misaligned - it could be the engine mounts Check it out

Our Associate Editor here at VINshyTAGE AIRPLANE Norm Petersen has also had an interesting experience with his airplane Heres his explanation

Carburetor Fuel Hose Replacement

Certain glitches can be very difficult to run down My J-3 Cub with a Contishynental C90-8 engine developed a frustratshying habit of sagging off about 150200 rpm while in cruise The slowdown was accompanied by a notable engine roughshyness as if one cylinder was not doing its job Checking both mags during the sag off revealed nothing Response to apshyplying carb heat was also normal Hmm Perhaps a valve was hanging up in one of the cylinders Copious additions of Marshyvel Mystery Oil changed nothing Even Surefoam was tried in an effort to loosen up the valves No help Maybe our problem was related to the fuel sysshytem

A different carburetor from another C-90 was tried - in addition to the normal sag off the carb leaked and eventually the float sunk The original carb along

A few months ago in Andrew Kings article on cable splicing we mentioned that you would most likely have to find an old splicing clamp or make you own Soon afshyterward we received an example of a cable clamp made by the nice folks at Wanco Tool Company 9840 Kings Ridge Rd Colorado Springs CO 80926-9639 Their Fax number is 719540-9180 Its a spring loaded tool neatly constructed out of De1shyrinreg plastic and stainless steel The knurled handles allow you to hold the tool in your hand while working on your cable splice or you can secure it in a vice A lever lock secures the plunger so your thimble and cable can be held in place

with a new $118 Delrin needle valve and a new used float was installed and the sag off diminished in regularity howshyever it still persisted A close inspection of the fuel system revealed a collection of cottonwood seeds (the fuzzy kind you see floating lazily in the early summer skies) had formed a mat of fuzz about 1116 inch thick on top of the brass fuel strainer in the sediment bowl Eureka This must surely be the heart of the problem

However removal of the fuzzy mat and reassembly was followed by the usual sag off of the engine although not quite as frequent Various experts volshyunteered numerous suggestions such as leaky intake manifold (we replaced all four intake gaskets at the cylinder head) and possible flopping baffle in the mufshyfler (a close check revealed nothing loose)

Stan Gomoll asked about the fuel hose to the carburetor It had not been changed in the nine years I have owned the Cub We carefully assembled a new hose with new end fittings and installed it between the sediment bowl and the carshyburetor (Apparently the old hoses begin to separate between the plies and shrink internally We cut the old hose apart and the hole in the hose was not round - it was now a very odd shape - somewhere between square and lumpy See the photo)

In the last 14 hours of flight the enshygine has only sagged off a couple of times We have not totally cured the problem but we are getting closer to a solution

Like I said in the beginning some of these glitches can be a real bearcat to run down Anybody else have any ideas

PASS IT TO ~~lJuck An information exchange column with input from our readers

Oil changes and why In a follow-up tn the articl e in la st month s Vintage Airshyplane I had intended to write about how to go about doing an oil change The more I thought about it the more I felt maybe Id better talk about what the o il actually does for your engine

Aircraft e ngine o il does a numbe r of things besides leak and make your engine compartment dirty It serves a number of purposes and if you ll bear with me fo r a bit I ll refres h your me mory and ma ybe give you some reason to change it once in a while

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed

Enough for now it s over to you

Basically o il serves you and your e nshygine in several functions it lubes it cleans it helps cool the engine It acts as a buffe r or cushions the shocks of operation it seals the rings and valve guides to enhance comshypression and it protects the machine surshyfaces even when the engine isnt running

The oil has to do all these things consisshytentl y or wea r and eve ntu al des tructio n will result What say we review how the oil does all these things

Lubrication friction reduction Try to visualize jillions of mi cro-mini little ball bearings everywhere in your engine That is what oil is Higher viscosity bigger little balls simple eh

Cleaning The ash dispersant additives in todays modern oils hold the contamishynants and dirt that used to become sludge in suspension The stu ff rides around and doesnt stick and hide in the corners cause it cant The additives are doing the job the manu facture r made the m fo r Look how quick the o il ge ts dirty When you change oil at the manufact urer s recommended inshyterval youre getting rid of all these potenshytial acid etchers and combustion associated dirt

Cooling takes place because the oil cirshyculates The constant flow of o il is much greater than the engine actually just needs fo r lubrica ti on It circul ates and reaches places where you couldn t possibly direct ai r o r wa te r a nd as it mixes with th e in shycoming cooler oil the temperature is steady and constant Even if you dont have an o il

routed through the crankcase - that assists with cooling the o il An external o il tank a nd the associa ted lines a lso disperse the hea t But wait a minute Don t ass um e that COLD oil is better All these little oil balls work best at the normal oil opera ting te mperature Those te mp e ratures a lso help to vaporize accumulated moisture and fu e l see page pas t th e rings du e to ove rshypriming

The cushion effect is best visualized by imag ining how th e connectin g ro d goes ba ngin g up and do wn a t 2300 rpm It s moving in two directions - both linear and circular and all kinds of forces are placed o n the jo urnal s pi sto n pin ring grooves and other moving parts as well A prope r weight oil is also hanging on like crazy and e ffective ly sealing beca use it is so te nashycious Those little balls take quite a beatshying Small wonder they wear out get dirty and need changing

The protection we get for our machined parts cylinder wall s valve trains and the like comes fro m the film th at clings to all these surfaces long afte r shutdown T hese new formulated multigrade o ils a re great Caution word here Don t le t tha t e ngine se t fo r wee ks and th e n go o ut th e re a nd

prime the dickens out of it and start it withshyout some pre-oiling Even the big boys like th e T -28s a nd th e B-1 7 run t he s t a rte r through at least two comple te revolutions before they start This assures the oil has a chance to wet things up I personally like to pull the prop thro ugh on the first preshyflight of the day I do it on the Champ and the Sedan and any other engine I preflight I ge t to fee l the compression so me times referred to as the poor boys compression check and I can listen to the magneto imshypulse snap and for any unusual noises that I can t hear if the engine is running

So fo lk s cha nge th a t o il regul a rl y Don t assume that since the engine has not been used for a couple months and the o il looks clean tha t it is Long periods of sitshyting will a ll ow the co ntamina nts and the sludge to settle to the bottom of the case The first run afte r a long layoff will result in these contamina nts mixing it up aga in and mi ght eve n damage th e e ngine if it isn t changed as soon as its noticed
