(c) In accordance with the local regulations:
1 Remove all the spilt fuel.
_ 2 Clean the fuel spillage from the area on the ground (hard
_
standing).
(d) Examine the holes in the drain mast to find which hole the fuel comes from.
NOTE : The top hole is from the APU shrouded fuel-feed line.
____ The bottom hole is from the center tank ventilation area.
(e) Look for signs of fuel leakage in the areas that follow: NOTE : The fuel leakage can be caused by incorrect assembly,
____ damage, the natural deteriation of fuel sealant or an unserviceable seal.
1 The main under carriage bays.
_
2 The center tank.
_
(f) If a fuel leak is found, repair all the leaks:
- (Ref. AMM TASK 51-76-12-300-001)
- (Ref. AMM TASK 51-76-12-300-002)
- (Ref. SIL 57-0086).
(g) Continue with step (3).
(3) Do the procedure Check Fuel Leak Monitor 500QM (center tank) for Evidence of Fuel Leakage (Ref. AMM TASK 28-11-00-200-002).
(4) If:
(a) No fuel is found in the fuel leak monitor 500QM (center tank), troubleshoot the APU fuel-feed line as follows:
NOTE : The logic for step (a) is.
____ The APU fuel-feed line does not have a leak monitor, if the leak monitor 500QM does not show fuel, the source must be the APU shrouded fuel-feed line.
1 Do a Leak Test of the APU Fuel Line:
_ a Do an operational test of the APU fuel pump system to purge
_ the fuel line (Ref. AMM TASK 28-22-00-710-001).
b Do the leak test of the APU fuel line (Ref. AMM TASK 28-22-
_ 00-790-002) or if applicable (Ref. AMM TASK 28-22-00-210-001).

c Examine the APU Fuel Line for leaks.
_
NOTE : Leaks are not permitted.____
d_ If you find leaks, replace the items of the fuel line, as
necessary (Ref. AMM TASK 28-22-47-000-001) and (Ref. AMM
TASK 28-22-47-400-001).
(b) Fuel is found in the leak monitor 500QM (center wing box), do (Ref. TASK 28-11-00-810-801).

B. Do the FLSS BITE Test (Ref. AMM TASK 28-46-00-740-001).
NOTE : If the aircraft is already supplied with electrical power, reset
____ the FQIC. (Open, then after 5 seconds, close the two C/Bs 1QT and 2QT). The FLSS BITE test is carried out once a short time after power up. After a two minute delay to allow the FQIC to do the BITE test, continue.
NOTE : The intercell transfer valves (ICTVs) are not tested by the
____ COMMAND FLSS BITE option. (This option only available with 07 FQIC Software Standard).
