(24) If no fault is found:

 - continue with the procedure which now tests the L refuel valve with right wing fuel pumps pressure.

 (25) On the panel 40VU, release (out) the L TK PUMPS P/BSWs to switch off the left wing tank fuel pumps.

 (a) Make sure the OFF legends come on.

 (26) On the panel 40VU, push the P/BSW-FUEL/X FEED (4QE) in to release out (CLOSED).

 (a) On the FUEL page, make sure the crossfeed valve shows closed.

 (b) On the center tank rear spar, make sure the ACTUATOR-FUEL CROSSFEED VALVE (5QU) see/feel indicator is in the closed position.

 (27) On the panel 800VU, put the REFUEL VALVES switch for the LEFT tank to the OPEN position.

 (28) On the panel 40VU, push (in) the R TK PUMPS P/BSWs.

 (a) Make sure the OFF legends go off, and the FAULT legends come on momentarily.

 (29) On the FUEL page, make sure the right wing inner cell fuel content decreases and the left wing inner cell fuel content increases.

 (30) On the panel 800VU, put the REFUEL VALVES switch for the LEFT wing to the NORMAL position.

 (31) On the FUEL page, make sure the left wing inner cell fuel content and the right wing inner cell fuel content become stable and stay stable for twenty (20) minutes.

 (32) If the fuel continues to flow (leaks past the valve) when the VALVE-REFUEL, L WING TK (7QU) is closed, do a check and replace if necessary:

 - the VALVE-REFUEL, R WING TK (7QU) (Ref. AMM TASK 28-25-51-000-001), and (Ref. AMM TASK 28-25-51-400-001).

 (33) If an (unexplained) fuel transfer/migration (still) continues, do the procedures:

 - (Ref. TASK 28-15-00-810-815)

 - (Ref. TASK 28-25-00-810-810).

R **ON A/C 301-399,

R A. Procedure
R (1) If necessary, release (out) the P/BSW-4QE.
R (2) Get access to the actuator, crossfeed valve (5QE) (Ref. AMM TASK 28-
R 23-51-000-001).
R (3) Do a check of the crossfeed actuator-5QE and valve-10QM installation

R (interface) to make sure that they are installed correctly (Ref. AMM R TASK 28-23-51-400-001). R (a) Make sure that the V-clamp, that attaches the actuator to the
R valve, is installed correctly.
R 1_ If necessary, re-install (Ref. AMM TASK 28-23-51-400-001).
R (b) Make sure that the see/feel indicator shows closed.
R 1_ If the see/feel indicator shows:
R a_ Open, do the procedure (Ref. TASK 28-23-00-810-801).
R b_ Closed, do step (4).
R (4) Replace the VALVE-FUEL CROSSFEED (10QM) (Ref. AMM TASK 28-23-41-000-
R 001), and (Ref. AMM TASK 28-23-41-400-001).
R (5) Do the test given in Para. 3.A.
R (6) If no fault is found:

R - set the aircraft maintenance configuration as follows to test the

R DEFUEL/XFR valve with fuel pump pressure:
R (a) If necessary, do the EIS start procedure (ECAM only) (Ref. AMM
R TASK 31-60-00-860-001).

R (b) On the ECAM Control panel 11VU, push (in) the FUEL P/BSW.

R 1_ Make sure the FUEL System Display page is shown on the lower
R ECAM Display Unit (DU).
R (c) On the panel 40VU, push (in) the P/BSW-FUEL/X FEED (4QE).
R 1_ On the FUEL page, make sure the crossfeed valve shows open.
R 2_ On the center tank rear spar, make sure the ACTUATOR-FUEL

R CROSSFEED VALVE (5QU) see/feel indicator is in the open R position.

 May 01/04 CESR (d) On panel 800VU, put the MODE SELECT SWITCH to the DEFUEL/XFR R position.

R 1_ Make sure the OPEN light comes on.
R 2_ On the center tank rear spar, make sure the DEFUEL/XFR
R ACTUATOR (11QU) see/feel indicator is in the open position.

R (e) On the panel 800VU, put the REFUEL VALVES switch for the RIGHT R wing to the OPEN position.
R (f) On the panel 40VU, push (in) the L TK PUMPS P/BSWs.
R 1_ Make sure the OFF legends go off, and the FAULT legends come
R on momentarily.

R (7) On the FUEL page, make sure the left wing tank fuel content decreases
R and the right wing tank fuel content increases.
R (8) On the panel 800VU, put the MODE SELECT SWITCH to the OFF position.

R (a) Make sure the OPEN light goes off.
R (b) On the center tank rear spar, make sure the DEFUEL/XFR ACTUATOR
