Overwing (Gravity) Refuel

TASK 12-11-28-650-006-A
Overwing (Gravity) Refuel

WARNING: OBEY THE FUEL SAFETY PROCEDURES.

WARNING: STOP THE FUEL TANKER 60 m (196.85 ft) FROM THE AIRCRAFT NOSE WHILE THE WEATHER RADAR OPERATES. DO NOT OPERATE THE FUEL TANKER/PUMP UNIT UNTIL YOU STOP THE OPERATION OF THE WEATHER RADAR.

WARNING: MAKE SURE THE AREA AROUND THE AIRCRAFT IS SAFE BEFORE YOU START THE REFUEL/DEFUEL PROCEDURE. IN THE SAFETY AREA, DO NOT:

SMOKE
MAKE SPARKS OR FIRE
USE ANY EQUIPMENT WHICH IS NOT APPROVED FOR REFUEL/DEFUEL PROCEDURES.

AIRCRAFT FUEL IS FLAMMABLE.

WARNING: DO NOT GET YOUR CLOTHES SOAKED WITH FUEL.

WARNING: DO NOT SPILL FUEL ON THE ENGINES OR THE BRAKES. IF YOU SPILL FUEL ON ENGINES OR BRAKES THAT ARE HOT, IT CAN CAUSE FIRES.

1. Reason for the Job

NOTE: It is recommended that you keep to one type of fuel. Although approved types can be mixed if necessary to continue operation. Refer to Section 2 of your Flight Manual (Ref. FM Section 2) for a complete list of approved fuels. Refer to Airbus Cold Weather Operations Information and Operations Policy Fueling Procedures for safety precautions with mixed fuel.

C. Aircraft Maintenance Configuration

WARNING: MAKE SURE THAT YOU BOND THE FUEL TANKER TO THE AIRCRAFT. IF YOU DO NOT, AN ELECTRICAL DISCHARGE CAN OCCUR WHICH CAN CAUSE AN EXPLOSION OR FIRE.

(1) Obey the local regulations for grounding (earthing) the aircraft. If you must ground (earth) the aircraft:

Ground (earth) the fuel tanker and the aircraft correctly (Ref. AMM TASK 12-34-24-869-001).

NOTE: You must bond the fuel tanker to the aircraft. Obey the local regulations for grounding (earthing).

(2) Bond the fuel tanker to the aircraft (Ref. AMM TASK 12-34-24-869-001).
(3) Make sure that the chocks do not touch the tires. The weight of the fuel can lower the aircraft and catch the chocks.
(4) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(5) In the cockpit:
(a) Do the EIS (ECAM only) start procedure (Ref. AMM TASK 31-60-00-860-001).
(b) On panel 11VU, push the FUEL pushbutton switch (in).
(6) Monitor the aircraft fuel configuration.
(7) If the intercell transfer valves are closed:
(a) Put the ACCESS PLATFORM 3M (10 FT) in position below zone 622.
(b) Open the access door 622KB.

Put the doorstay into the doorstay bracket to hold the access door 622KB in position.

(8) On the refuel/defuel control panel 800VU, make sure that the MODE SELECT switch is in the OFF position.

NOTE: If operating in battery power, do not keep the door open longer than necessary because the battery can discharge.

4. Procedure
Subtask 12-11-28-650-060-A ** ON A/C NOT FOR ALL

CAUTION: BEFORE YOU CLOSE THE CROSSFEED VALVE, MAKE SURE THAT THE FUEL PUMP(S) IS(ARE) OFF. THIS WILL PREVENT DAMAGE TO THE CROSSFEED VALVE.

A. Overwing (Gravity) Refuel

NOTE: It is recommended that all of the fuel pumps are switched to off to do this procedure. This decreases the risk of possible fuel spills. It is permitted for the wing-tank pumps to be switched to on, if:

there is a minimum of 750 kg (1653 lb) of fuel in the applicable wing-tank.

(1) On the panel 40VU, make sure that:

the X FEED P/BSW 4QE is not pushed (in) (the ON and OPEN legends of the P/BSW are off).

CAUTION: KEEP THE RATE OF REFUEL THE SAME AS, OR LESS THAN, THE RATE OF FLOW THROUGH THE TRANSFER VALVES.

(5) Before refuel, record actual fuel quantity indicated on preselector 5QT and fuel tanker. When refuel is complete do a discrepancy check.
(6) Start the pump on the fuel tanker/pump unit.
(7) Use the fuel pumps in the wing tanks to move the fuel to the center tank from the wing tanks (Ref. AMM TASK 28-25-00-869-001).
(8) Monitor the fuel quantities continuously on the ECAM lower DU.

NOTE: The overwing refuel point is not at the highest point on the wing. Thus you cannot refuel the wing tanks to full.

(9) When the fuel quantities are correct, stop the pump on the fuel tanker/pump unit.
(10) Remove the fuel nozzle from the overwing refuel point.
(11) Install the overwing refuel cap 44QM(45QM).
(12) Disconnect the grounding (earthing) cable of the refuel nozzle from the wing ground (earth) connection.
(13) Do the refuel procedure again for the other wing.
(14) Correct the fuel configuration (move the fuel from the inner cells of the wing tanks to fill the outer cells of the wing tanks (Ref. AMM TASK 28-25-00-869-001)).

NOTE: Make sure that the outer wing fuel tanks are full. This will prevent the risk of structural damage.
