 (d) The jet-pump (feed/drive supply) pipe-lines, between:

 - the left-wing fuel-manifold (adjacent to the check valves 33QM and 34QM, in-board on RIB2) and the jet-pump 66QM

 - the right-wing fuel-manifold (adjacent to the check valves 36QM and 35QM, in-board on RIB2) and the jet-pump 69QM.

 (e) The jet-pump (suction) pipe-line(s), between the suction inlet pickup point in the left (right) wing vent/surge-tank and the jet-pump 66QM (69QM).

 (f) The jet-pump (output/discharge) pipe-line(s), between the jet-pump 66QM (69QM) and the fuel discharge (outlet) adjacent to the intercell transfer valve 28QM (30QM) outboard of RIB15.

 (g) Repair/replace all the unserviceable fuel pipes and connections (Ref. AMM TASK 28-00-00-000-001) and (Ref. AMM TASK 28-00-00-400-001).

 (10) If the fuel spillage occurred with the fuel pumps set to ON (Post Flight Config) do:
 (a) Examine the applicable engine fuel feed line, Air Release Valve and, if necessary, replace (Ref. AMM TASK 28-21-41-000-001) and (Ref. AMM TASK 28-21-41-400-001).

 (b) If necessary, do Internal Fuel Leak Which Causes a Fuel Imbalance or a Discharge From a NACA Vent During Taxi or Flight (Ref. TASK 28-21-00-810-825).

 **ON A/C 301-399,
 A. Procedure
 NOTE : The tests listed here are a guide only.
____
 They can be done in an order (any) best suited to:

 - the local conditions in which the fuel spillage occurred

 - the tools and equipment available.

 If only a test is called for, take any resulting ECAM WARNING(s), failure message(s) and/or observation(s) to TSM Page Block (PB) 101 for the applicable Task number and do the necessary trouble shooting.
 (1) Make sure that the applicable refuel (transfer) task, as follows, was/is complied with in all respects:

 - Pressure Refuel with Automatic Control (Ref. AMM TASK 12-11-28-650-003)

 - Pressure Refuel with Manual Control (Ref. AMM TASK 12-11-28-650-004)

 - Pressure Refuel without Electric Power (Ref. AMM TASK 12-11-28-650-005)

 - Overwing (Gravity) Refuel (Ref. AMM TASK 12-11-28-650-006)

 - Fuel Transfer (Ref. AMM TASK 28-25-00-869-001).

 (2) Do the Inspection of the Tank Venting System (Ref. AMM TASK 28-12-00-200-001).

 (3) On the opposite side wing to the fuel spillage, do a General Visual Inspection of NACA Vent Intake For Signs of Obstruction (blockage) (Ref. AMM TASK 28-12-47-200-001).

 (4) Do an Inspection of the Overpressure Protectors (Wing and Vent Surge Tanks) (Ref. AMM TASK 28-12-41-200-003).

 (5) If the fuel spillage was from the left side, do the Inspection of the Overpressure Protector 96QM (Ref. AMM TASK 28-12-41-200-002).

 (6) Do the Operational Test of the Refuel System (Ref. AMM TASK 28-25-00-710-003).

 Nov 01/04 CES

 (7) Do the Operational Test of the Defuel System (Ref. AMM TASK 28-25-00-710-002).

 (8) Do the Operational Test of the Crossfeed Valve (Ref. AMM TASK 28-23-00-720-001).

 (9) On the inboard side of RIB22, do a check of valves that follow for a full and free movement:

 - CLACK VALVE (214QM) (CLACK VALVE (216QM))

 - CLACK VALVE (215QM) (CLACK VALVE (217QM)).

 NOTE : In normal operation the clack valves in the RIB22 let the fuel
____ that has entered the vent/surge tanks return to the related wing tank. The clack valves do not let fuel enter the vent/surge tanks from the wing tanks. If the two (both) clack valves in the RIB22 remain in the closed position the fuel level in the tank will increase because it cannot drain back to its related wing tank. If, during these conditions, a fuel surge were to occur during the refuel, less fuel can be held in the vent/surge tank than if it was continuously drained and almost empty. This will increase the possibility of a fuel spillage because the usable capacity of the vent/surge tank has been reduced.
