Shut off unnecessary electrical equipment in 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
Keep fuel servicing nozzles free of snow, water,
and mud at all times.
Carefully remove snow, water, and ice from the
aircraft fuel filler cap area before removing the filler cap
(fig. 2-44). Remove only one aircraft tank filler cap at
any one time, and replace each one immediately after
the servicing operation is completed.
Wipe all frost from fuel filler necks before
servicing the aircraft.
Drain water from fuel tanks, filter cases, and
pumps prior to first flight of the day. Preheat, when
required, to ensure free fuel drainage.
Avoid dragging the fueling hose where it can
damage the soft, flexible surface of the deice boots.
Observe NO SMOKING precautions.
Prior to transferring fuel, ensure that the hose is
grounded to the aircraft.
Wash off spilled fuel immediately.
Handle the fuel hose and nozzle cautiously to
avoid damaging the wing skin.
Do not conduct fueling operations within 100
feet of energized airborne radar equipment or within 300
feet of energized ground radar equipment installations.
Wear only nonsparking shoes near aircraft or
fueling equipment, as shoes with nailed soles or metal
heel plates can be a source of sparks.
Prior to removing the fuel tank filler

to the filler opening.
FILLING FUEL TANKS.
Fill tanks as follows:
Attach bonding cables to aircraft.
Attach bonding cable from hose nozzle to
ground socket adjacent to fuel tank being

Remove fuel tank filler cap and fill main tank
before filling corresponding auxiliary tanks.
Secure applicable fuel tank filler cap. Make
sure latch tab on cap is pointed aft.
Disconnect bonding cables from aircraft.
DRAINING MOISTURE FROM FUEL
Twelve (12) fuel drains are installed (plus two drains
for the ferry fuel system, when installed) to remove
sediment from the fuel system.
