Weight and Balance Sheet and Operations Record Each airplane is weighed at the factory be-fore licensing. A copy of the weight and balance is included with the license documents, known as the operations record. This operations record is issued by the C.A.A. and must be kept with the aircraft at all times. It furnishes, in effect, a complete history of the airplane and its charac-teristics, and it is necessary to have these papers when the airplane is relicensed, when periodic checks are made or when any repairs or alterations are made to the aircraft. A center of gravity check is required only when install-ing equipment other than that listed above as class III equipment. These papers are to be car-ried in the airplanes at all times.
Ski Plane Status 1. U.S. Approved 2. Canada (Complies with structural require-
ments when landing gear strut 08300-21 or 08311-22 is used).

II.II.II.II. AIRPLANE DESCRIPTIONAIRPLANE DESCRIPTIONAIRPLANE DESCRIPTIONAIRPLANE DESCRIPTION A. GENERAL
The Luscombe Model 8 series is a two place side by side strut braced high wing cabin mono-plane powered with a single four cylinder air–cooled engine of sixty-five or seventy-five horse–power. The airplane is designed as a cross country airplane for the private flier, but is well suited to student training. It is equipped with dual controls, those on the right side being removable. Wide doors are provided on both sides of the fuselage for easy entrance and exit. Deep seat cushions may be removed to permit use of seat pack parachutes.
B. FUSELAGE The fuselage is a monocoque dural structure. The cross sectional shape is maintained by a minimum number of stamped 17ST aluminum alloy ring bulkheads, over which are laid 17ST alclad skins which vary in thickness from .032 to .064 inches. With skins of this thickness no stiffening members are necessary except at a few places where stresses are concentrated, as in the vicinity of the doors. This reduces repair bills by reducing the number of pieces in the airplane. Certain skins around the cabin are stamped to shape, but the majority are rolled to secure the required contour. Skins and bulkheads are made with such pre-cision that they are interchangeable, facilitat-ing repairs. All skins and bulkheads aft of the cabin have the rivet holes pre-drilled in jigs, so that if necessary to remove a whole section of skin in making a repair, a new piece can be fit-ted and riveted without requiring the�drilling of any holes. The seat bottom is riveted to the fuselage and serves to reinforce it. The seat back is hinged to provide access to a 4½ cu. ft. baggage compart-ment. The Model 8D has an additional 3½ cu. ft. in a “Hat Throw” type of compartment behind the pilot’s seat. By removing the baggage com-partment the whole of the tail portion of the fuselage is easily accessible. Just ahead of the seat a heavy box bulkhead is provided to take the principal flying and land-ing stresses and distribute them to the airplane. Both wing lift struts are brought to a fitting on this bulkhead, to which the main landing gear strut is also connected. The oleo landing gear
shock absorbing strut is housed in the center of this bulkhead, where it is accessible for serv-icing. The engine mount, of welded 4130 steel tub-ing is bolted to the fuselage at three points, and is quickly detachable. The upper and most stressed engine mount bolt transmits its load directly to a steel tube Vee which is bolted to the fuselage at the wing root front spar connec-tion. This steel Vee also protects the occupants in the event of a nose-over. The engine is fully cushioned with rubber shock bushings.
Individual safety belts solidly bolted to the fuselage are standard equipment.
The fuselage was subjected to numerous static and dynamic tests to prove its strength. The following static tests were made with 115% of the design failing load and no permanent dis-tortion occurred:
1. High angle of attack.
2. Three point landing.
3. Maximum horizontal and vertical tail sur-face loads.
4. Drag compartment of landing gear loads in three point and level landing.
5. Control system loads.
6. Fuel tank loads.
The dynamic tests, made with full load, were:
1. Level landing. The fuselage was dropped on both wheels from a height of 18 inches. There was no failure and the load factor developed was 4.
In a second test, the fuselage � was�dropped 7.6 inches on one wheel to dem-onstrate the torsional rigidity of the fuselage. There was no failure and a load factor of 3 was developed.
2. Three point landing. The fuselage was dropped on the wheels from a height of 16¼ inches. A factor of 4.2 was developed and there was no set.
A separate test�was�made�on the� tail skid, equipped with both shoe and wheel. The test was made with � 15% � overload�and there was no failure. Accelerations were not recorded. Height of drop �was�16¼ inches.

Castellated nuts may be used throughout.
In general, holes for bolts which turn or are highly stressed or subject to reversed stresses, are ream fits. Others are drilled.
4. Rivets A17ST rivets are suitable for use anywhere on the airplane. These rivets need no heat treat-ment or preparation of any kind but are driven in the “as purchased” condition. A few alum-inum or 17S rivets are used on the airplane in lightly stressed and difficult-to-rivet locations.
The following marks distinguish the various types of rivets:
A17ST—small dimple on head.
17S—small tit on head.
Aluminum—plain head.
The most used rivet sizes and the correspond-ing drill sizes are listed below:
3/32 rivet Drill #40 (.098”)
1/8 rivet Drill #30 (.1285”)
5/32 rivet Drill #20 (.161”)
3/16 rivet Drill #10 (.1935”)
Brazier heads are used on exposed rivets. Other rivets are usually round head except where space limitations demand a counter sunk head or bazier head.
5. Pyralin That used in the center windshield panel and in the cabin roof window is .060” thick. That used for the sides of the windshield and door windows is .040” thick.
When necessary to replace pyralin, use the original windshield for a pattern by which to cut the new pieces. Small machine screws may be substituted for the 3/32” aluminum rivets if more convenient.
6. Vinylite Lifetime Windshield Late model ships were equipped with a formed lifetime windshield. This may be in-stalled in any model and you will find it very different. The upper section has a formed dome effect which increases the visibility slightly. This windshield outlasts several of the stand-ard pyralin type and will not discolor or crack under normal use.
C. METAL REPAIR METHODS 1. Forming Small metal parts for repairs are usually formed by bending over a block of appropriate size and shape. Either hardwood (Maple) or steel block may be used for dural parts but steel parts require steel blocks. The edges of the blocks should be rounded off so that the inside radius of the bend is not less than one and a half times the metal thickness for steel and not less than twice the metal thickness for dural. Bending is done by clamping the metal block in a vise and hammering the part over the form with a mallet or using a block of wood and a hammer. Use only a smooth jaw vise or protect the part with another piece of metal.
Avoid tool marks and smooth rough edges before bending because they may be starting points for cracks. Where two bends are to inter-sect, the corner thus formed should be relieved by cutting away the metal as shown below.
