TASK 28-25-00-710-003-A
Operational Test of the Refuel System


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.
WARNING: PUT THE SAFETY DEVICES AND THE WARNING NOTICES IN POSITION BEFORE YOU START A TASK ON OR NEAR:
  • THE FLIGHT CONTROLS
  • THE FLIGHT CONTROL SURFACES
  • THE LANDING GEAR AND THE RELATED DOORS
  • COMPONENTS THAT MOVE.
MOVEMENT OF COMPONENTS CAN KILL OR CAUSE INJURY TO PERSONS AND/OR CAN CAUSE DAMAGE TO THE EQUIPMENT.
WARNING: MAKE SURE THAT THE WHEEL CHOCKS ARE IN POSITION. MOVEMENT OF THE AIRCRAFT CAN BE DANGEROUS.

F Refuel/Defuel Coupling ** ON A/C NOT FOR ALL
   (1) Make sure that the fuel tanker is in the correct position.
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.
   (2) Obey the local regulations for grounding (earthing) the aircraft:
     (a) Ground (earth) the fuel tanker/pump unit and the aircraft correctly (Ref. AMM TASK 12-34-24-869-001).
   (3) Bond the fuel tanker/pump unit to the aircraft (Ref. AMM TASK 12-34-24-869-001).
   (4) Remove refuel coupling cap 41QM.
   (5) Make sure that the hose coupling of the fuel tanker/pump unit is clean.
   (6) Connect the hose coupling of the fuel tanker/pump unit to the aircraft refuel/defuel coupling.
   (7) Set the fuel tanker/pump unit to the refuel mode.
   (8) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
   (9) Energize the Electronic Centralized Aircraft Monitoring (ECAM) system (Ref. AMM TASK 31-60-00-860-001).
