Where
did my
summer
go?
F
ll has arrived in
the
Midwest,
and
our
summer
has slipped
away from us.
Where
did it
go? t seems as though it was
only a few short weeks ago I
was all excited
about what
I
thought
would be a spring
and summer
full of
travel, new
opportunities,
and
more
aviation in my life. Then, the blunt
ness of my "real" life and its responsi
bilities ran me over like a truck
For
an abundance
of reasons, I
don t ever get everything on my
bucket list crossed off during each sea
son of flying. How about you? Even
after
what
I believe to be careful plan
ning and
a real
attempt
to engage my
self in the activities or
events
I plan
to
attend,
I
always
seem to come
up short. Oh
well,
2010 may prove
to be a new beginning for my avia
tion
dreams. This
is
not to
say
that
I
had a lousy summer-I did finally get
that ever-elusive P-S1
Mustang ride
I always promised
to
treat myself to.
Thanks, Jimmy, it was a real hoot
So
far this year, I
spent about
five
cently shocked and deeply saddened
to hear
of
the loss
of my
contem
porary
from the In ternational Aero
batic
Club (lAC). Vicki Cruse was a
good
friend
and a strong leader for
the
lAC. She was
an
extremely effec
tive president of
the
l
AC, and
her loss
will affect
not
on ly
the
aerobatic
com
munity,
but
also EAA and all of its
divisions. She was a
wonderful
lady
and
an
awesome competitor, and
my heart
goes out
to
her many close
friends
and
family members
who
will
certainly miss her. Most
of
all, I wi ll
miss her wonderful smile.
Your Vintage Aircraft Association
board o f directors will be meeting
again in Oshkosh in mid-October.
We
are already deep
into the
planning of

the
aftermath of a wildly successful 2009
event, we are working
hard to
make
the 2010 event the best yet. Be as

With regard to
our
finances, your
Vintage Aircraft Association is cur
rently on firm ground.
Like
everyone,
we are experiencing increasing
op
erational costs, and we are
reacting
to these relatively new challenges.
During the
2009
convention, the
volunteer
leadership created
a
new
sub-committee that has launched a
renewed effort to improve
our
finan
cial outlook to better manage
these
increases as
they
develop. I
am
happy
to report that excellent progress has
alr
eady been made to develop new
income streams in the area of non
dues revenue. Like
most
associations,
dues typically make up only a small
percentage of
the
revenue needed
to
operate.
This development
com
mittee is working
primarily
on con
cepts that will attract new members
as well as develop new
member
ben
efits to strengthen
our
renewal rates. I
will keep you posted on our progress
throughout
the current fiscal year.

Preserving th Vintage Fleet
Vintage ER application process
checklist
now
available
Interested in becoming ap
pOinted
as a vintage designated
engineering
represen
ta
ti ve
(VDER)
to
help with the
unique
challenge
of preserving
the
vin
tage fleet? A new checklist cre
ated by EAA and the
FAA
will help
with
the application process,
and
it's now available through
the Vintage Aircraft Association
(VAA) website at www Vintage
Aircraft.org. Since the
VDER
des
ignation
was
announced
by
the
FAA during this year's EAA AirVen
ture Oshkosh, a number
of
mem
bers have expressed a desire to ap
ply for appointment as a VDER.
Some of
those members have
asked
what the next
step
is in
the
process to become a VDER;
the
checklist
outlines the
pro
cess, and all of it is overseen by
the FAA. The most important as
pect
of the
application
process
is to read FAA Order 8IOO.8C.
lt's rather dry, but
the
applica
tion process is actually
contained
in that document (see Chapter
4). Also, as
stated in the open
ing paragraphs of
Chapter
4, you
should
contact the
FAA,
stating
your
interest
in the program . In
the
case of the VDER program,
you should contact David Swartz
cated here : www. VintageAircraft.
org/der/der_checklist.pdf
Keep in mind
that this pro
gram is run
entirely
by the FAA,
and
all matters
related
to ap
pointments as VDERs are at
the
FAA s discretion. The VDER des
ignation
is
simply an
addition
to an already existing program
within the FAA, and all proce
dures
and
policies in place for
the DER program will also apply
to VDERs.
We're pleased to see so much
interest
in
the
program, and
we
appreciate the
willingness of
the
FAA
to
add
this designation
to the
DER
program.
We
look
forward
to hearing back
from
the
FAA when its first
group
of
VDERs is
appointed.
Changes Proposed for Pilot
Flight Instructor Rules
The FAA has issued a notice of
proposed rulemaking (NPRM) for
changes
to
rules governing certi
fication of
pilots,
flight instruc
tors, and
pilot schools.
Accord
ing to
the
FAA,
the reasons for
these
revisions
include
changing
aviation technologies,
recent
re
search
findings, and a
rededi
cated focus on ensuring that pi
lots have
adequate training and
qualifications
to
operate safely in
place with Canada) .
The FAA is also proposing that
pilot
schools
can
use Internet
based training
programs
with
out requiring a
physical
ground
training facility. The FAA is also
proposing to
allow
pilot schools
and provisional pilot schools
to
apply
for a combined private pi
lot certificate and instrument rat
ing course. In addition, the
FAA
proposes revisions
to
the defini
tion of complex airplane.
Public
comments must be
submitted to
the
FAA
on
or be
fore
November
30, 2009. In
structions on submitting a com
ment are contained within the
NPRM. To access the NPRM

Robert Lock's article in the Au
gust 2009 Vintage Airplane (liMy
Thoughts on
Radial
Engines )
was interesting. I have
been
flying
Cessna 195s for 30 years
with
the
Jacobs
engine
and can appreciate
the
technology
improvements the
Jacobs had over the older radials
and the improvements that are still
being made to
the
Jacobs engine.
The reason he is
having
trouble
with 100LL is that the lead pres
ent
in 100LL
is
four
times
higher
than in 80/87, which has only 0.5
grams
per
gallon.
100LL was an
outgrowth of the old 100/130 that
usually had 3 grams per gallon. By
refining changes, limiting
the
lead
to
2 grams per gallon, and adding
toluene,
the
new 100LL meets the
100/130 fuel specification.
It
can be
used in engines designed for 80/87
but often not without lead fouling
problems. So the chemical deposits
Robert
is
seeing in the combustion
chambers of his engines are sub
duced my exhaust valve problems.
Recently, steel exhaust valve seats
were approved and
have became
available on the Jacobs engines, re
placing the aluminum bronze seats
which
seemed
to
be
more
suscep
tible
to lead
deposits sticking
to
them. I had the conversion installed
on all my cylinders after only 200
SMOH
because of extensive exhaust
valve and guide problems.
So
far, af-
ter 140 hours, the results look good,
but time will tell i f this solves
our
valve problems.

Design heck for a
Major Alteration
I was greatly interested in Robert
Lock's article
in the
May 2009
Vin-
tage Airplane "S
ome Thoughts on
Restoration and Airworthiness."
It
made me wish that an article like this
by an experienced
master
like Bob
had been published 30 or 40 years
proved 210-hp
engine in
weight
and horsepower, the
authorities
in my country easily approved
the
engine substitution as typically
allowed in
the
FAA 337 forms for
similar aircraft.
Not so when in
the
1990s I
launched on
a similar, but
maybe
slightly more daunting project, a
1929 Fokker Super Universal.
At
the outset I figured the engine swap
from the original P&W R1340 Wasp
C
to
the later and more
reliable
R1340 Wasp S3H1 would be a sim
ple 20-minute field approval. Al-
though
the
engine specs indicated
the horsepower would be upped
from 420 to 550, by controlling
the rpm
with an authentic
fixed
pitch,
ground-adjustable prop, I
could keep the power down
to
450,
which had been okayed in field ap
proval paperwork from the 1930s.
With the airplane 99 percent com
plete, the engine running, and only
the paperwork to finish, I was advised
by the authorities that this wouldn't
do. I
was
reqUired to provide a design
check
on
the front fuselage frame
for
the increased weight, torque , and
thrust of the later engine
for
the lim
iting horsepower of 450. Yuck
I chose to get some advice from
my local DER (deSignated engineer
ing representative). We decided to
use the design criteria established in
an
earlier
document
as
being
most
appropriate-we
chose

able
book
was nalysis and Design

Bruhn. Both texts are probably part
of a
DER
s library.
The complex tubing structure
was
plotted and
entered into the
computer
analysis
using
software
called Multiframe 3D.
The
very
hard part of the analysis labori
ously done so many years ago with
pencil and slide rule had
been
the
resolution of forces along the many
paths and directions of the tubular
structure. This was resolved in sec-
onds by computer. I include com-
puter diagrams showing the mem-
bers for one
of the loading
cases.
After the loading cases for weight,
thrust, and torque were spit
out
by
the computer, these were
entered
in a spreadsheet containing
the 21
members with their lengths, sizes,
and capacities as compression col-
umns or tension members.
Wonderful-the engineering cal-
culations showed the fuselage was
capable of carrying the new engine.
Without
getting into the
com
plexities of the computer and paper-
work analysis, I would say
that
this
approach is much easier, safer,
and
more appropriate than the static
load test which Bob agonized over
for his reported four
and
one-half
years. I admit, I agonized and fussed
over my situation for nine months
before being granted approval. The
procedures are not dead easy and
require the help of an engineer, and
preferably a DER familiar with air-
craft design requirements.

good
reason. They were proudly
standing under the protective
wing of
their
1941

Super Chief, which they fin
ished restoring earlier this year.
The restoration
took them eight
years, on and
of f
.The first year or
so,
they concentrated on build
ing new ribs and spars. But then
they took a hiatus for a couple
of
years, according
to Ed,
and
then worked especially hard
for the past two years. "Jerry
made the first
flight
in the plane
this March;'
says Kale.
As
far
as

scalded rabbit.
We
were in a
Cessna

as
he did,
as

as
he
did:

When asked
why
they were inspired
to
acquire
the
Super Chief, Langley quickly responds
with
a hearty laugh, "Well,
it's our age! Actually it 's a little
bit
younger. We were looking for a younger girl, so we found one:' Langley and Kale had
each helped restore
an
airplane before tackling the Super Chief as their own project. They also fly
with
the Civil Air
Pa
trol and have been coming
to
Oshkosh for
about
15 years.
As
for
the
Super Chief's future, Kale smiles broadly
as
he pro
claims, "We're going

others Ryan and Cory Johnson of Dodgeville, Wisconsin, are only in thei r 20s,
but
they've already
been coming
to
Oshkosh for 25 years. They are the th ird generation of aviators in their family, and
they'
ve
been helping their father restore several airplanes throughout the years. Ryan just earned
his airframe and powerplant certificate; Cory is currently work ing on his flight instructor certificate
and nurturing a dream
to
become a competitive aerobatic air show
pilot
.The brothers are obviously hooked
on aviation, and with good-natured laughter, they explain that they've "had the conversation at times about
what our lives would be like
without
aviation-and we can't imagine it! It's all we do, is work on airplanes.
That 's the center of our lives:'
So it
isn
't surprising that they are bubbl ing over with enthusiasm when they explain their attraction to Air
Venture: "We just
can
't wait to come back. It ... it just builds every year from winter into spring, and you talk to
people about the projects they're working on and if they will be here this year. It's the anticipation of who's
going
to
be here, and who's going
to

Jerry started coming

mixture of pilots and non-pilots.
As
I was coming home one day, I
noticed a large moving van in front of
one of the condos, and I stopped and
introduced myself to Bill Moses, the
newest airpark resident. Bill is not a
pilot, but he was lured to the airpark
by a mutual friend who lives and
flies here. Bill is wheelchair-bound,
and
over the next few months he
joined in many of the airpark events
and even joined EAA Chapter 1414.
fuselage and wings and was based
closely on the 1930 Curtiss-Wright
Junior.
It
was popular in
the
west,
as many farmers used it for spotting
their stock as
well
as coyote hunting.
With the pilot out in front, there are
no struts or engine parts to block the
view or the shot.
Our Woody Pusher was bui lt in
1976 by a man named Bond, and
he gave it the serial number 007. He
constructed the wings and spars out
of wood,
but
used steel tubing for
8/20/2019 Vintage Airplane - Oct 2009
http://slidepdf.com/reader/full/vintage-airplane-oct-2009 21/44
warm clothes and took it around the
patch, just so he could say he
had
flown it, too.
We
then
put
it in the hangar
and
started
to
look at it closely. I t
had
been built in
1976,
but
soon
af
ter that it
had
been dismantled and
stored. After a series of owners, it was
put
back
together and
flown for a
few years before we came
into the
picture.
At
some point in time some
one had painted over the fabric with
enamel paint, and it was starting to
crack and peel
off.
After talking about
it for a few minutes, we decided that
it might be a good idea to re-cover
the wings and tail feathers. Since it
was winter and only a fool would fly
it in the winter (what did that make
me?), now was the time.
It
turned out to be a good idea, be
cause when we got the old fabric
off,
we found that the glue used 30 years
ago was drying out and small parts
were starting to fall off inside. We
re-glued the entire
thing and
did a
general cleanup on the wings. We re-
m<jved the electrical system because
we
had no plans
on
flying it at night
and re-covered the wings and tail
feathers. Since the plane was for fun,
we chose a whimsical paint scheme
and painted it bright orange and yel
low with Poly-Tone paint.
Now
that
we had the ideal air
plane for Bill's ride, the next problem
was how to get
Bill
into the airplane.

DWIGHT
HUNT INGTON
AND
THE H 12
L IGHTPLANE
BY J CKMc
R E
Shortly after World War
I,
homebuilt airplanes
that
were
similar to what are now classified as ultralights began to ap
pear in this country. Pilots and engineers such as Jack Irwin
in California,
Ed
Heath in Chicago, and Harvey Mummert
and Dwight Huntington in
the
New York area apparently
felt
that
the large war-surplus
Jennys
and Standards, al
though
cheap, were
not the
answer
to the
private pilot's
needs. One of the earliest of these ultralights was the Hun
tington
H-12, which was probably also the first to be de
signed to professional engineering standards. The H-12 was
a small mid-wing monoplane of wood construction, cov
ered with unbleached muslin and powered with a Harley
Davidson V-twin motorcycle engine.
Huntington
Motorcycle Engined
Monoplane that
in
cluded a three-view drawing, speCifications, and details of
construction. The cost of building the airplane was esti
mated to be
not
more than $80, excluding engine and pro
peller. A V-twin motorcycle engine of from 12 hp to
15
hp
was recommended, and this was said to give a maximum
speed of 60
mph
and a rate of climb of 240 feet/minute.
While visiting George Hardie Jr. during
EAA
Oshkosh
1986, George showed me some beautifully drawn one-fourth
scale detailed construction plans of a motorcycle engine
powered airplane called the Dixie
No.
I , with the title block
labeled C.E. Lay Aeroplanes, Blue Ash , Ohio. The external
dimensions of this airplane seemed to agree exactly with
8/20/2019 Vintage Airplane - Oct 2009
http://slidepdf.com/reader/full/vintage-airplane-oct-2009 23/44
Creek Road Cincinnati, Ohio. What the connection
was
be
tween C.E. Lay and Huntington remains a mystery.
Not very much is known about Dwight Huntington since
he doesn't appear in any of the h o ~ Who in Aviation books
that
we
have seen. In 1928 he was an engineer on the Vulcan
American Moth airplane
and
became chief engineer
when
Harvey and Wilson Doyle left to form the Doyle Aero Corpo
ration. He continued as chief engineer when Vulcan became
the Davis Aircraft Corporation in 1929. During
the
Depres
sion years of the 1930s he worked for several aircraft com
panies and wrote a number of articles on lightplane design
that appeared in
ero
Digest in 1930
and
1931,
and
articles
describing the new airplanes at the aircraft shows. Hunting
ton's last known place of employment was Skylark Aircraft
Mfg.
Co. of Venice, California, which he left at about the
end of World War II. The company was a reorganization of
the Pasped Company tha t built the Skylark during the 1930s.
While there Huntington was engineer on a pusher airplane
project called
the
Skycraft 447, which was intended for
the
postwar market. One airplane of this design was built in
1947. Sometime after leaving the Skylark company, Hunting
ton is reported to have died of Parkinson's disease.
Thanks to
John
Underwood for information
on
Hunting
ton's career. Huntington was a real pioneer in lightplane de
sign, and the H-12 with a more reliable engine would have
probably made a very practical sport plane for its time.
The
following
is excerpted from Ae
ri l
Age January
3 1921:
The
Huntington Motorcycle
ngined Monoplane
The real problem in efficiency, as
far as
aeronautical en
gineering
is
concerned,
is
to design a machine that will fly
well with low power, or, in other words, a machine having
a heavy loading per horsepower. This, the biggest problem,
is
within
the reach
of
the
amateur
builder
or
student
of
moderate means.
In order to design a successful machine around a motor
of low power,
it
is necessary to make accurate calculations
and
work out all details very carefully so that all exposed
parts will have a minimum resistance and that
the
weight
will be kept as low as possible consistent with safety.
can be made lighter owing to
the
fact
that
fewer parts are
required, which makes this type ship inexpensive, easier to
construct, and economical to operate.
There are numerous advantages in building your own
ship aside from the pleasure of owning your own plane. The
builder gains an accurate knowledge of practical aeronautics,
he knows just what the machine can stand in flight, and can
make his own repairs and keep his ship in perfect trim.
liThe cost of building the monoplane described, pro
viding
the
work is done by
the
builder, should not exceed
$80. This figure, of course, does not include either engine
or propeller.
The resistance of an aeroplane which determines the
horsepower required for propulSion, increases as the square
of velocity, or in other words, the resistance of a ship trav
eling at 100 mph
is
nearly four times the resistance of
the
same ship
when
traveling at 50 mph. For this reason it
is
difficult
to
obtain high speed without a powerful engine.
But in order
to
fly
at
a comparatively low normal speed,
ei-
ther a large wing area is required, necessitating a bigger and
usually heavier plane, or else a wing section of very high
lift must be employed. The U.S.A. No. 4 section was chosen
because it not only gives a good lift at
the
angle of best
LID
(that is 4 degrees), but also because it makes possible a ship
of ample strength and small size.
The ordinates of this wing for a 54-inch chord are given
in the table below.
With a view of simplicity and ease of construction, with
a
minimum
expense, parts difficult to make, such as metal
fittings, have been eliminated wherever
pOSSible
and but
few small parts, such as turnbuckles, clevis pins, shackles,
etc., are called for in the design.
As
an example of
the
small stresses imposed upon a ship
of this size, let us consider
the
conditions of
the
rear struts.
The center of pressure of
the
U.S.A. No.4 section at 2 de
grees incidence is 67 percent of the chord from the leading
edge, equivalent
to
about 36 inches for
the
54-inch chord.
The front spar is located 8-3/4 inches from the leading edge,
and the rear spar 28-3/4 inches behind the front spar. At 2
degrees incidence, therefore, the rear spar will carry approxi
mately 95 percent of the total load. Each wing, of course,
carries one-half the total weight, or 200 pounds. From this

wings are covered with unbleached muslin 1 yard
wide, sewn to the ribs and given three coats of dope. The ai
lerons are built up and covered similar to the wings; they are
hinged to
the
rear wing spars by eyebolts.
li he four lift struts are identical and interchangeable.
They are of solid spruce with a Navy No.1 section as de
scribed in
erial ge
issue of December 29 1919. These struts
have a safety factor of 12 so that an engine of 20-30 hp may
be installed in the machine if better performance is desired.
They are 1-1/4-inch thick by 3-3/4-inch wide and about 6 feet
in length. Pin joints are provided at each end where the struts
join the wing and fuselage. Fittings are of cold rolled steel.
For both the wing and undercarriage braCing, 3/32-inch
cable is used in conjunction with No. 325 turnbuckles.
Fuselage
li he fuselage has a length of 12 feet 5 inches, a maxi
mum depth of 33 inches, and is 20 inches wide at the pilot's
cockpit. The longerons
and
struts are of spruce, the former
3/4-inch square section. Diagonal bracing is of veneer strips
1/8 inch by 1 inch of greater width at the ends where they
are attached to
the
longerons
and
struts by wood screws.
This method of bracing has been used successfully on other
machines; it possesses
the
advantage of light weight
and
low cost since it does away
with
a considerable number of
small parts such as fittings, turnbuckles, clevis pins, shack
les wires, ferrules, bolts, etc.
Standard stick
and
foot bar controls are installed,
the
foot bar actuating the rudder. For aileron and rudder, steel
tube or ash may be used, for control stick,
the
former be
ing preferable.
li he seat
is
constructed of veneer, well lightened, placed
low in the fuselage, 10 inches above the lower longerons. In
this position the pilot's shoulders come below the upper lon
gerons and consequently a fuselage of less width
is
required.
Undercarriage
An undercarriage of convent ional form
is
fitted to two
well-streamlined spruce Vee struts and fastened by fittings
of 16 gauge cold rolled steel. The Vees are spaced by an axle
streamlined in a lifting wing section, built
up
of spruce
and
veneer, a groove running the length of the wing, providing

The clinic,
held
at St Louis's
Creve Coeur Airport (aka, Dauster

friendly grass runways,
ran from
May 28 to 31. They have another
clinic
scheduled there October
1 through 4,
along with
a
clinic
at Hollister Municipal Airport in
Hollister, California. David Bur-

one of the
Stearman flight
instructors
and
one of the group's
two F.A.S.T. representatives, says,
More training was done in Stear-

anything else .

is
important.
There
are
thousands still flying.
There
is an
extremely strong core group of
people.

to be a large
and
active Signatory [to F.A.S.T.].
Stearman Flight conducts four-
day clinics. The first day, a Thurs-
day
evening, is a ground school
and briefing for the next day, when
flying begins. Friday starts
with
a
morning review of the briefing,
answering
of
questions, and fa-
miliarization of the flight area . By
afternoon, the instructors are get-
ting serious with the training. You
have to be a good Stearman pilot to
begin with, says Burroughs. You
almost have to be able to control
the airplane almost unconsciously
to maintain formation.
Friday
starts
out
reasonably
early
and runs until
dark.
Sat
urday
starts
at
sunrise
as the in
structors try to
get

two
hours,
counting the

time. There
are five
phases of
formation
flying, says
Burroughs. Number one is the
briefing
.
Number two
is
getting

and getting into forma-

The old designation was replaced
sometime in
the
19S0s
and
became 17S-T (2017-T3), 24S-T (2024-T3) ,
and
A17S-T
(2117-T4). 2024-T3 is
the
most
commonly
used
high-strength
alloy for light,
general-aviation
type airplanes.
It
is
possible
to obtain any
of
the aluminum
alloys
in the softest state, which is annealed-designated
with an 0 in the code. Thus there can be 2024-0,
which can be
hand-
or machine-shaped
into
complex
parts,
then
hardened by heat-treating.
Before we look at
the
strain-harde
ned
alloys, let
me
give a quick
discussion
of hardening by heat
treat
ment
. The pure
aluminum
has been alloyed primarily
with copper (and a few
other
trace elements). The ma
terial is
heated
in a
controlled
fashion in an oven
to
920-970°
F
then
immediately
removed
and quenched
in water. This is called solution heat
treatment
(SHT).
The SHT process is similar to adding a catalyst to
an
epoxy resin, to cross-link molecules and
harden
the
material. The copper diffuses
throughout the
material
and
is cross-linked in
the
grain structure causing it
to
be very hard
and
strong.
Aluminum
alloy 2024
that
has
been heat-treated
,
naturally aged,
and
then rolled is deSignated 2024-T3.
This alloy
is
primarily used in structural applications
and
must
be riveted
with
2117-T4
rivets
(dimpled
head). This rivet will be coded as
AD
(AN470AD4-4).
This aluminum alloy, 2024-T3, can be bent or rolled,
but it cannot be shaped
by
hammering or stretching. It
is
not
weldable.
The alloys that
gain strength by
cold-working are
the old
2S,
3S
,
and
S2S . New designations are
1100
(2S) , 3003
(3S), and
SOS2 (S2S). Alumi
num
designated as SOS2
is
alloyed with
magnesium. I f
the
material is in its soft
est state, the designation is followed
with
an 0, as
in
SOS2-0. If these ma
terials are
strain-hardened
(by
cold
rolling), an H will be displayed, as in
SOS2-H.
Then, two additional
numbers
will be added to show
the
type of strain
hardening
(the
first number) and the
ENDING
on
its head; the
AN
(Army/Navy) code will show an A
(AN470A4-4).
I have fabricated fuel
and
oil tanks from SOS2-H34
aluminum (strain-hardened,
stabilized
, and in the
1/2 hard
condition). My fuel lines are fabricated from
SOS2-0
tubing in the
annealed condition. This tubing
can be bent and flared easily.
Finally, I should brief you
on
a few addit ional terms
we use
in
aircraft structures.
tress
means
the
load act
ing
on a material.
Strain means
the
deformation
of a
material
by
an applied load. tren
g
th is defined as (1)
tensile, which means to resist forces
tending
to stretch
or
lengthen
material, (2) yield, which means load
that
causes initial
indication
of
permanent displacement
and (3)
ultimate,
which means load applied beyond
which
the
material will fail.
There are five stresses that the aircraft will encoun
ter in flight or while
static
on the ground. Figure 1
identifies the five stresses the aircraft will
encounter
in operation.
These stresses are
bending which
actu
ally causes two types of stress to a member. The part of
the
me
mber on the
outside
of
the bend
is
under
ten
sion
, and
the part
on
the
inside of
the bend is under
compression.
Torsion is
a twisting force.
Tension
tends
to
pull
apart or stretches
the member. Compression
presses
together or
tends
to
crush a
component.
h

when
two
components
are bolted or riveted together.
When

to the
bolt.
If
the
force becomes greater
than the
shear strength of
the
bolt, it will be cut
as

When
discussing
the ultimate strength of an
alumi
num
material, it is easy to see
the
difference between
structural (carries in-flight
and
landing loads)
and
nonstructural material. The ultimate strength of
5052-H18 (strain hardened to full hard) is 29,000 psi.
The ultimate strength of 2024-T3
heat-treated
alumi
num is 68,000 psi. The ultimate strength of 6061

aluminum is 42,000 psi. One can

the
difference
between

and heat-treated aluminum.

On the other hand, 4130 that is used for most com

Normalizing is the heating of alloy 4130 to

and
allowing the material
to air

When

One last
comment on
steel alloys
that

heat

it
cannot be repaired unless
it
is subject
to
exactly
the

type of
heat treatment. Don't
let
any

which can

to
do unless one
has the

Risk
Management
think we are all
in
agreement
that
flying
is
an inherently
dangerous
endeavor.
The
risks
we face as we operate our air-
craft
are
numerous,
and
the
only
thing
that
really makes
flying
safe
is
the
way
that
we
manage
these many risks. There are
many
tools
that
we
can
use
to aid
in
this management.
For some pilots
risk manage
ment
seems
to
come naturally.
Whether
this
comes about as a re-
sult of one's DNA
or
is
the
prod
uct of
the
way
one
is
raised by
one's parents
and early teach
ers, I am
not
really
sure.
But for
whatever
reason,
some folks
are
just naturally
cautious.
For other
people, however, the tendency to-
ward a
more
reckless attitude does
indeed
exist.
Charles Lindbergh
once
said:
What kind of
man
would live
where
there is no
daring?
I don't
believe in taking foolish chances,
but
nothing can
be
accomplished
is cast for
how
we will
manage
the
many risks of flying for the rest of
our flying careers.
To this
day,
I still remember
my
first flight lesson. My
instruc
tor, since he was paid only
for
time
when the
Hobbs
meter
was
running, hurried through the pre-
flight inspection and
quick
ly
got
me insta
lled in the left
seat
as he
was
starting the
engine.
Now
that
the engine was running,
he
started
to
take a
little
more
time,
but we
all know what a horrible classroom
the
cockpit is,
and
that,
combined
with my excitement to
get
in the
air, left
most
of
what he had to
tell
me
lost
to
my awareness.
However, I do recall what he
said as we taxied
onto the
runway
and started our takeoff roll. Push
the
throttle all
the way in, and
steer
wit
h
your
feet. Keep
looking
out the window, and when it feels
right,
pu
ll back on the yoke.
Not
a word was
sa
id about checking to
establish that we were making full
learned first were the things that
stuck. To this
day, I
have to con
sciously check
the
gauges before ro-
tation. It is not something that I
do
naturally,
and
I attribute
that to the
rule of primacy.
But I
have digressed from
dis-
cussing
the
numerous tools that we
have available to aid us in manag-
ing
the risks of aviation. I would
like
to share with you
some
of the
tools that I use. The list
is not
all-
inclusive but includes those things
that I
have
found most
important
in
keeping
me
from being
my own
worst enemy.
Heading
the
list of tools, for me,
is the
concept of slowing down
and
not being in a hurry. I f we rush
through
the many
different tasks
that we face
as
a pilot,
the
possibil-
ity of missing, or overlooking, just
one sma
ll
thing
could
lead
to our
demise.
So at
the
top
of
my
list are
the words SLOW OW

minimums
and, more importantly, adhering to
once established. They should be

dynamic
and
change as necessary
to reflect your currency
and
profi
ciency, or lack thereof.
Closely related
to establishing
personal
minimums
is
learning to
recognize the "hazardous attitudes"
that we might have residing within
our
being. Regardless of whether
they are anti-authority, macho, in
vulnerability, impulsivity, or resig
nation, everyone of these attitudes
could kill us. However, recognizing
them
is
onl
y the first step. More im
portantly is developing "antidotes"
to these attitudes
that
will work to
counteract them.
With a set
of
realistic personal
minimums, as well as a "bag" of an
tidotes for our hazardous attitudes,
we will now be much less suscep
tible
to
the
man
y
operational
er
rors" that could remove us from a
long life of flying.
Next on my list is
the
use of
checklists. Even if
the
airplane we
are flying
is
as simple as a J-3 Cub,
the use of checklists can help us in
ensuring that we have not missed
anything
in
the
safe
operation
of
our aircraft. Mind you, I am
not
ad
voca ting these checklists as do
lists, but there have certainly been
times in my flying
when
a distrac
tion
of some form has allowed me
to miss performing some action. So
I put
the
use of checklists, to assist
me in making sure I haven' t forgot
ten to do something as a result of a
distraction, high
on
my list of tools.

I am referring
to
some of the hand
held equipment that offers us the
ability
to
obtain data-link weather
information.

for
the
local

GPS

weather information at the push of

one
impor
tant tip relative to the use of these
tools. The information that you get
on them is history.
It
is
at least five
minutes
old
when
you first receive
it. The tool is fantastic for devel
oping strategic
plans
for weather
avoidance, but it should never, ever
be used as a tactical tool
Rounding
out
this
short list of
tools that
we can use
to help
us
manage
our
risks is the help
that
can
be
gotten
from air traffic con
trol and flight
service stations.
More
than
once, as I was reaching
my wits' end in trying to resolve an
in-flight problem (usually weather
related), a
controller
has come to
my assistance. So many of us were
taught, back in the "
dark
ages, "
that
one should
never
declare
an
emergency.
If
you do, you'll have
to file a report, and you know what
that

as much
as
pilots, and
they would
much
rather just help
you resolve what
you, the
pilot
in command,
determine to

iting help. Good risk management
means
that
we will use any
and
all
tools available.

Amelia Earhart Biopic
Set for Release
On October 23, Fox Searchlight
Pictures will release
Amelia
starring
two-time Academy Award winner
Hilary Swank
as Amelia Earhart,
founding member and first presi
dent of the Ninety-Nines, and the
first
woman to
be decorated with
the
Distinguished
Flying Cross,
presented after becoming the first
woman to fly solo across the At
lantic. The movie, directed by Mira
Nair, is a biopic expected to detail
the
extraordinary life of adventure,
celebrity, and continuing mystery
of the noted aviatrix.
Richard Gere, Cherry Jones,
and
Ewan McGregor round out the cast
for this major Hollywood produc
tion, much of
which
was
shot
in
Canada. While a
movie
summary
was not available at press time,
the
movie trailer shows significant effort
was put into creating accurate non
flying replicas of two aircraft flown
by Earhart,
her record-breaking
cherry red Lockheed Vega
and
the
,
\ L
Swank s portrayal of Amelia
is
complemented by the strong resem
blance the Academy Award-winning actress has to
Ms
Earhart.
Fokker Tri-motorFriendship in which
she
flew as a passenger,
becoming
the first woman to cross the Atlan
tic by air. During production a few
of
our fellow
members
and others
were asked to participate with their
aircraft, and it will be interesting to
see to
what
extent their efforts will
appear in the movie. A quick review
of the trailer shows the
BOcker
Jung
mann of Larry and Andrew Ernwe
wein from Ontario, Tom Dietrich and
the
Tiger Boys' Thruxton Jackaroo,
and
a Beech Staggerwing all stand
ing in
for
air show biplanes from the
early 1930s. Grace McGuire's 1935
Lockheed lO-E , N1602D, is featured
in the film as well.
After becoming
the
first woman
to
fly
across
the Atlantic, Ame
lia was
thrust
into a new role as
America's
sweetheart-the
legend
ary goddess
of
light, I
known
for
her bold, larger-than-life charisma.
Yet, even with her global fame so
lidified,
her
belief
in
flirting
with
danger and standing up
as
her own
outspoken woman never changed.
In
the
summer of 1937, Amelia set
off
on
her most
daunting
mission
yet: a solo flight around
the
world
that she and
her
husband, George
Putnam, both anxiously foresaw
as
destined, whatever
the
outcome,
