Pressure Refuel without Electrical Power

TASK 12-11-28-650-005-A
Pressure Refuel without Electrical Power

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 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.

NOTE: This procedure is not applicable to refuel the Additional Center Tank(s) (ACTs).

A. Safety Precautions
(1) You must obey the refuel/defuel safety precautions (Ref. AMM TASK 12-11-28-650-001) (Ref. AMM TASK 12-11-28-650-002).
(2) Put the ACCESS PLATFORM 5M (16 FT)- ADJUSTABLE adjacent to the refuel coupling 40QM.

D. Aircraft Maintenance Configuration

WARNING: MAKE SURE THAT THE FUEL SUPPLY HOSE IS CORRECTLY CONNECTED TO THE COUPLING BEFORE YOU REFUEL/DEFUEL THE AIRCRAFT. DO NOT CONNECT THE FUEL SUPPLY HOSE IF THERE ARE SIGNS OF DAMAGE TO THE AIRCRAFT COUPLING LUGS OR SLOTS.

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) Remove the refuel coupling cap 41QM.
(4) Make sure that the coupling of the fuel supply-hose is clean, then connect it to the aircraft refuel coupling.
(5) Release the Magnetic Level Indicators (MLI) of the tanks to be refueled (Ref. AMM TASK 12-11-28-650-007).
(6) If the intercell transfer valves are open:

the inner and outer cells of the wing tanks fill together
the full capacity of the wing tank is less than normal
make an entry in the aircraft technical log, to check the fuel configuration before the subsequent flight.

4. Procedure
Subtask 12-11-28-650-056-A ** ON A/C NOT FOR ALL

A. Pressure Refuel without Electrical Power

WARNING: BE CAREFUL NOT TO FILL THE TANKS MORE THAN NECESSARY NEAR THE END OF THE REFUEL. BECAUSE THERE IS NO ELECTRICAL POWER, THE HIGH-LEVEL PROTECTION SYSTEM WILL NOT OPERATE. THUS THERE IS A RISK OF OVERFILLING AND FUEL SPILLAGE.

CAUTION: DO NOT REFUEL OR DEFUEL THROUGH THE TWO REFUEL/DEFUEL COUPLINGS AT THE SAME TIME. THIS IS TO PREVENT PRESSURE DIFFERENCE PROBLEMS.

CAUTION: DO NOT LET THE REFUEL PRESSURE BE MORE THAN THE MAXIMUM PRESSURE OF 50 PSI (3.45 BARS). IF YOU DO NOT OBEY THIS INSTRUCTION, DAMAGE TO THE AIRCRAFT OR EQUIPMENT CAN OCCUR.

(1) Start the pump on the fuel tanker/pump unit.
(2) Push and hold in the manual plunger(s) on the refuel valve(s) of the applicable fuel tank(s).
(3) Use the MLIs to monitor the quantity of fuel in each tank (Ref. AMM TASK 12-11-28-650-007).

NOTE: Refer to the fuel tables for the maximum capacity of each fuel tank and for the total fuel capacity. If the intercell transfer valves are open, the full capacity of a wing tank is less than normal.

NOTE: If necessary, to dispatch with full fuel load, use the ECAM to make sure the outer cell is full. This will prevent the risk of structural damage.

(4) When the quantity of fuel in a tank is correct, release the manual plunger on the related refuel valve.
(5) When all the fuel quantities are correct, stop the pump on the fuel tanker/pump unit.
(6) Make an entry in the aircraft technical log, to check the fuel configuration before the subsequent flight.
