2-89. 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. Observe the following
During warm weather open fuel caps

When conditions permit, the aircraft
shall be positioned so that the wind
will carry the fuel vapors away from
all possible sources of ignition. The

distance of 20 feet between the fueling
vehicle and the fuel filler point.
Shut off unnecessary electrical equipment on the
aircraft, including radar and radar equipment. The master
switch may be left on, to monitor fuel quantity gages, but
shall not be moved during the fueling operation. Do not
allow operation of any electrical tools, such as drills or
buffers, in or near the aircraft during fueling.
Keep fuel servicing nozzles free of snow, water, and
mud at all times.
Carefully remove snow, frost, water, and ice from
the aircraft fuel filler cap area before removing the fuel filler
