MAULE Super Rocket M-7-235C Maintenance Manual page 16

PROCEDURE:
1. Place each of the wheels on a scale with the tailwheel elevated to place the airplane in
approximately the flight attitude.
2. Place a level on the leveling mark and leveling lug on the bottom of the right wing near
the root. Adjust the height of the tailwheel until the aircraft is level.
3. Measure the following distances:
a. Wheel base (L) - the horizontal distance from the tailwheel weight point (center of
axle) to the main wheel weight point (center of axle).
b. Main Wheel Station (D) - the horizontal distance from the main wheel weight point
(center of axle) to the datum line.
4. Measure the weights at the following points:
a. Right Main Wheel..................= ____________ Lbs.
b. Left Main Wheel....................= ____________ Lbs.
c. Tailwheel, with tare =____________Lbs., minus tare of ______________ Lbs.
= net Tailwheel wt. (T) of _________________ Lbs.
The above empty weight includes unusable fuel of ** lbs. at 24 inches and 12 quarts of oil
at minus 34inches for the O-540 engine and 8 quarts of oil at minus 34 inches for the IO-
540 engine, plus all items of equipment as marked on the accompanying Equipment
Lists. The certificated empty weight is the above weight less 24 lbs. drainable oil for the
O-540 engine or above weight less 16 lbs. drainable oil for the IO-540 engine at a minus
arm of 34 inches and for this airplane is _____________lbs. The corresponding empty
weight center of gravity is ______________inches.
5. Calculations for determining weight, C.G. and moment:
a. Center of Gravity (inches) =
i.e., C.G. = _____________ - ____________ = ___________inches.
b. Moment (inch pounds) = W x C.G.
i.e., Moment = _____________ x ____________ = ___________inch lbs.
**Use 18 lbs. for "A" or "B" tank configurations and 27.6 lbs. for "C" or "D".
