4. Fault Isolation
_______________
A. Inspection
(1) Do a visual inspection of the IDG1 (2) and external system (tubings, cooler) for oil leaks (Ref. AMM TASK 24-21-00-210-047).
(2) If you find no leak continue the trouble shooting procedure as follows.
B. Aircraft Maintenance configuration
(1) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(2) Do the EIS start procedure (Ref. AMM TASK 31-60-00-860-001).
C. Check of the IDG Drain Mast for Leakage NOTE : An internal oil consumption of 1 cc is permitted for each flight
____
hour or when the engines operate.
(1) Preparation for the test
(a) Make the thrust reverser unserviceable for maintenance (Ref. AMM TASK 78-30-00-481-041).
(b) Open the thrust reverser doors (Ref. AMM TASK 78-36-00-010-040).
(c) On the engine drain collector assembly, put a plastic container and a tube on the IDG oil drain (Ref. AMM TASK 71-73-49-000-006) (Ref. AMM TASK 71-73-49-400-006).
(d) Close the thrust reverser doors (Ref. AMM TASK 78-36-00-410-040).
(2) Engine operation WARNING : - ENGINE OPERATION MUST NOT EXCEED MINIMUM IDLE WHEN
_______ PERSONNEL ARE IN ENTRY/EXIT CORRIDOR.
- POSITIVE COMMUNICATION BETWEEN THE FLIGHT COMPARTMENT AND PERSONNEL IN ENTRY EXIT CORRIDOR IS NECESSARY.
- INLET AND EXHAUST HAZARD AREAS MUST BE STRICTLY OBSERVED BY PERSONNEL IN ENTRY/EXIT CORRIDOR.
(a) Start the engine (Ref. AMM TASK 71-00-00-710-003) and let it become stable at minimum idle for 5 minutes.
(b) Operate the engine at 70 percent N1 and let it become stable for 5 minutes.
(c) Operate the engine at minimum idle and let it become stable for 5 minutes.
