MAINTENANCE MANUAL
FOR
MXT-7-180
Rev. F
16/37
PROCEDURE:
1. Place each of the wheels on a scale with the airplane in approximate level flight atti-
tude.
2. Place a level on the leveling mark and leveling lug on the bottom of the right wing near
the root. Adjust the extension of the nosewheel oleo until the aircraft is level, or flatten
the tire if necessary.
3. Measure the following distances:
a.
Wheel base (L) - the horizontal distance from the nosewheel weight point (center
of axle) to the main wheel weight point (center of axle).
L = __________________ Inches
b.
Main Wheel Station (D) - the horizontal distance from the main wheel weight point
(center of axle) to the datum line.
D = __________________ Inches
4. Measure the weights at the following points:
a.
Right Main Wheel..................= ____________ Lbs.
b.
Left Main Wheel....….............= ____________ Lbs.
c.
Nosewheel, (N)......................=_____________Lbs.
Total Weight as Weighted (W) = __________________ Lbs.
The above empty weight includes unusable fuel of ** lbs. at 24 inches and 8 quarts of
oil at minus 34 inches, plus all items of equipment as marked on the accompanying
Equipment Lists. The Certificated empty weight is the above weight less 16 lbs.
drainable oil 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) = D - N x L
W
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”.
