Proper procedures for handling JP-4 and
JP-5 fuel cannot be over stressed. Clean,
fresh fuel shall 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 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 cap (fig. 2-29). Remove only one aircraft tank filler
cap at any one time, and replace each one immediately
after the servicing operation is completed.
Drain water from fuel tanks, filter cases, and
pumps prior to first flight of the day. Preheat, when
required, to insure free fuel drainage.
Avoid dragging the fueling hose where it can
damage the soft, flexible surface of the deicer boots.
Observe NO SMOKING precautions.
Prior to transferring the fuel, insure that the hose
is grounded to the aircraft.
Wash off spilled fuel immediately.
i. 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.
2-88. FILLING FUEL TANKS.
Prior to removing the fuel tank filler cap,
the hose nozzle static ground wire shall
be attached to the grounding lugs that
are located adjacent to the filler opening.
Fill tanks as follows:
Attach bonding cables to aircraft.
Attach bonding cable from hose nozzle to
ground socket adjacent to fuel tank being filled.
Do not insert fuel nozzle completely into
fuel cell due to possible damage to
bottom of fuel cell.
Fill main tank before filling respective auxiliary
tanks unless less than a full fuel load is desired.
Secure applicable fuel tank filler cap. Make
sure latch tab on cap is pointed aft.
Disconnect bonding cables from aircraft.
2-89. DRAINING MOISTURE FROM FUEL SYSTEM.
To remove moisture and sediment from the fuel
system, 12 fuel drains are installed (plus one for the
ferry system, when installed).
2-90. FUEL TYPES.
Approved fuel types are as follows:
Army Standard Fuels. Army standard fuel is JP-
Alternate Fuels. Army alternate fuels are JP-5
