When the truck is in position and prepared as
above, conduct fueling operations as follows:
1. Secure all electronic and electrical switches on
the aircraft that are not required for fueling (plane
2. Verify that manned fire-fighting equipment is
in the immediate vicinity and upwind of the refueling
operation (refueler operators).
3. Attach the bonding cable between the refueling
equipment and the aircraft (plane captain).
4. Pull out the hose (or pantograph) and place it
in the proper position for refueling (nozzle operator and
5. Remove the refueling adapter cap from the
aircraft, and the dust cover from the pressure nozzle.
Inspect the face of the nozzle to make sure it is clean,
and verify that the flow-control handle is in the fully
closed and locked position (nozzle operator).
6. Visually inspect the aircrafts adapter (recep-
tacle) for any damage or significant wear. A worn or
broken adapter can defeat the safety interlocks of the
refueling nozzle, permitting the poppet valve to open
and fuel to spray or spill.
7. Lift the nozzle by the lifting handles, and align
the lugs on the nozzle with the slots on the aircraft
adapter. Hook up the nozzle to the aircraft by pressing
the nozzle firmly onto the adapter and rotating it clock-
wise to a positive stop (nozzle operator). The nozzle
must seat firmly on the adapter and not be cocked.
Cocking can indicate a malfunction of the nozzles
safety interlock system, which could lead to a fuel spray
8. Zero the refueling meter or the totalizer reading
9. Rotate the nozzle flow-control handle to the
FULL OPEN position. The handle must rotate 180
degrees to ensure the poppet valve is fully open and
locked (nozzle operator).
10. Upon receiving signals from the nozzle opera-
tor and the plane captain that the hook-up has been
completed and that they are ready to begin the fueling
operation, the refueler operator actuates the remote,
hand-held deadman control.
11. Once fuel flow has been established, test the
aircrafts precheck system (plane captain).
12. Fuel the aircraft as directed by the plane cap-
tain. The plane captain monitors aircraft vents, tank
pressure gage(s), and/or warning lights, as necessary.
13. When directed by the plane captain, release the
dead man control (refueler operator).
14. Rotate the nozzle flow-control handle to the
OFF and fully locked position (nozzle operator, and
verified by the refueler operator).
15. Disconnect the nozzle from the aircraft adapter
16. Stow the pantograph or hose (nozzle operator
and refueler operator).
17. Complete the paperwork (nozzle and refueler
REFUELING BY TRUCK
Overwing (gravity) refueling of aircraft from
trucks is done using the procedures as above but with
the following modifications:
The overwing nozzle must be bonded to the
aircraft via a nozzle bonding cable prior to removal of
the filler cap.
OverWing refueling with the aircrafts en-
gines operating (hot refueling) is NOT author-
The overwing nozzle is inserted into the air-
crafts refueling port. Metal-to-metal contact between
the nozzle and the aircraft fueling port must be main-
tained during the entire fueling operation.
All activities require that refueling vehicles be
constantly attended whenever the engine is operating.
The operator is considered in attendance when per-
forming tasks directly associated with fueling an air-
craft; for example, assisting the aircraft refueling
operator, transporting the hose. If the operator is to
leave his truck unattended, he must first
1. drive the truck clear of the aircraft;
2. place the air brake in ON and LOCKED posi-
tion, if applicable;
set the parking brake;
direct the front wheels to an open, unobstructed
stop the engine; and
