3. Fault Confirmation__________________
A. Check/Test
(1) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-004).
(2) Do a visual check of the differential pressure indicators of the APU generator scavenge filter and the APU lubrication filter.
4. Fault Isolation
_______________
A. If the differential pressure indicator confirms that the APU generator scavenge filter and/or the APU lubrication filter is/are clogged:
- remove the oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
- do an inspection of the removed oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
- do an inspection of the magnetic drain plug (Ref. AMM TASK 49-91-42-200-001).
- install the oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
(1) If the inspections show that the filter elements has caught: .copper wire particles, .nonmetallic flakes, .phenolic resin.
- remove the GEN-APU (8XS) (Ref. AMM TASK 24-23-51-000-001) and install a generator cover plate (Ref. AMM TASK 49-11-00-400-002),
- change the APU oil (Ref. AMM TASK 49-90-00-600-002),
- start and operate the APU for 15 minutes (Ref. AMM TASK 49-00-00-860-003),
- shutdown the APU (Ref. AMM TASK 49-00-00-860-004),
- remove the oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
- do an inspection of the removed oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
- do an inspection of the magnetic drain plug (Ref. AMM TASK 49-91-42-200-001).
(a) If you do not find contamination after 15 min. APU operation:
- remove the generator cover plate (Ref. AMM TASK 49-11-00-000-002),
- install a new GEN-APU (8XS) (Ref. AMM TASK 24-23-51-400-001)
- install the serviceable oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
(b) If you find contamination after 15 min. APU operation:
- install the oil filter elements (Ref. AMM TASK 49-91-41-200-001) and (Ref. AMM TASK 49-91-45-200-002),
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001),
(c) If the inspections show that the filter elements has caught brass or silver-plated steel particles:
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001).
B. Do the test given in para. 3.
