6.3 AIRPLANE WEIGHING PROCEDURE
At the time of delivery, Piper Aircraft Corporation provides each airplane with the basic empty weight
and center of gravity location. This data is supplied by Figure 6-5.
The removal or addition of equipment or airplane modifications can affect the basic empty weight and
center of gravity. The following is a weighing procedure to determine this basic empty weight and center of
gravity location:
(a)
Preparation
(1)
Be certain that all items checked in the airplane equipment list are installed in the proper
location in the airplane.
(2)
Remove excessive dirt, grease, moisture, foreign items such as rags and tools from the
airplane before weighing.
(3)
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. Then add the unusable fuel
(2.0 gallons total, 1.0 gallons each wing).
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
three minutes at 1000 RPM on each tank to insure no air exists in
the fuel supply lines.
(4)
Fill with oil to full capacity.
(5)
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.
(6)
Weigh the airplane inside a closed building to prevent errors in scale readings due to wind.
(b)
Leveling
(1)
With airplane on scales, block main gear oleo pistons in the fully extended position.
(2)
Level airplane (refer to Figure 6-3) deflating nose wheel tire, to center bubble on level.
