2-90. 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 precautions:
During warm weather open fuel caps slowly
to prevent being sprayed with fuel.
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 or abrasions. The
exhaust deposits contain lead oxide which
will cause lead poisoning.
such as drills or buffers, in or near the aircraft during
b. Keep fuel servicing nozzles free of snow, water,
and mud at all times.
c. Carefully remove snow, water, and ice from the
aircraft fuel filler cap area before removing the fuel filler
cap (fig. 2-30). Remove only one aircraft filler cap at any
one time, and replace each one immediately after the
servicing operation is completed.
d. Wipe all frost from fuel filler necks before
e. Drain water from fuel tanks, filter cases, and
pumps prior to first flight of the day. Preheat, when
required, to insure free fuel drainage.
f. Avoid dragging the fueling hose where it can
damage the soft, flexible surface of the deicer boots.
Observe NO SMOKING precautions.
Proper procedures for handling JP-4 and
JP-5 fuel cannot be over stressed. Clean,
fresh fuel shah be used and the entrance of
water into the fuel storage or aircraft fuel
system must be kept to a minimum.
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 fuel vehicle shall be positioned
to maintain a minimum distance of 10 feet
from any part of the aircraft, while
maintaining a minimum distance of 20 feet
between the fueling vehicle and the fuel filler
a. 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,
h. Prior to transferring the fuel, insure that the
hose is grounded to the aircraft.
i. Wash off spilled fuel immediately
j. Handle the fuel hose and nozzle cautiously to
avoid damaging the wing skin.
k. Do not conduct fueling operations within 100 feet
of energized airborne radar equipment or within 300 feet
of energized ground radar equipment installations.
l. Wear only nonsparking shoes near aircraft or
fueling equipment, as shoes with nailed soles or metal
heel plates can be a source of sparks.
