 A. Test
 (1) Do the functional test of the engine bleed-air supply-system (Ref. AMM TASK 36-11-00-720-004).
 4. Fault Isolation
_______________
 A. Make sure that the leak is on the same side of the leak warning.
 (1) Repair the ducts which cause the leak.
 NOTE : If the L WING LEAK ECAM warning comes into view on ground and
____
 if:

 -the packs are in operation

 -there is high OAT

 -you replaced the flow control valve (8HB)
 first do a check of the pack area or of the seals at the flow
 control valve.

 (a) If no leak is found on the wing ducts: - open the access door 471AL on the pylon
 -remove the engine 1 exchanger outlet temperature sensor (6HA1) (Ref. AMM TASK 36-11-17-000-001)
