necessary to service the aircraft except lubrication. The
lubrication requirements of the aircraft are covered in
the aircraft maintenance manual. Tables 2-7, 2-8, 2-9

2-87. FUEL HANDLING PRECAUTIONS.
Table 2-2, Fuel Quantity Data, lists the quantity
and capacity of fuel tanks in the aircraft. Service the
fuel tanks after each flight to keep moisture out of the
tanks and to keep the bladder type cells from drying out.

caps slowly to prevent being
sprayed with fuel.
WARNING
When aviation gasoline is used in a
turbine engine, extreme caution should
be used when around the combustion
chamber and exhaust area to avoid cuts
