WEIGHT AND BALANCE DATA
WEIGHING PROCEDURE
I
At the time of 1icensingPiper Aircraft Corporation provides each airplane with the licensed
empty weight and center of gravity location. This data is on Page 5-7.
The removal or addition of an excessive amount of equipment or excessive airplane
modifications can affect the licensed empty weight and empty weight center of gravity. The
following is a weighing procedure to determine this licensed empty weight and center of gravity
location:
1.
PREPARATION
a. Be certain that all items checked in the airplane equipment list are installed
in the proper location in the airplane.
b. Remove excessive dirt, grease, moisture, foreign items such as rags and tools
from the airplane before weighing.
c.
Defuel airplane. Then open all fuel drains until all remaining fuel is drained.
Operate engine on each tank until all undrainable fuel is used and engine
stops.
CAUTION
Whenever the fuel system is completely drained and fuel is re-
plenished it will
be
necessary to run the engine for a minimum of 3
minutes at 1000 RPM on each tank to insure no air exists in the fuel
supply lines.
d. Drain all oil from the engine, by means of the oil drain, with the airplane in
ground attitude. This will leave the undrainable oil still in the system.
Engine oil temperature should be in the normal operating range before
draining.
e. Place pilot and copilot seats in fourth (4th) notch, aft of forward position.
Put flaps in the fully retracted position and all control surfaces in the
neutral position. Tow bar should be in the proper location and all entrance
and baggage doors closed.
f. Weigh the airplane inside a closed building to prevent errors in scale
readings due to wind.
2.
LEVELING
a. With airplane on scales, block main gear oleo pistons in the fully extended
position.
