(b) If the inspections show that the filter elements has caught brass or silver-plated steel particles:
1_ 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),
2_ 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-

- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-001) and (Ref. AMM TASK 49-11-11-400-001).
R **ON A/C 063-099, 401-499,
A. If the test gives the maintenance message:
CHECK OIL FILTERS (8069KM)/(8076KM)
with the LRU TROUBLE SHOOT DATA menu information:
OIL FILTER SHOWS CLOGGED
Fault Code Number: 102
NOTE : The APU SHUTDOWNS report gives the message CLOGGED OIL FILTER -
____
CHECK OIL FILTERS (8069KM)/(8076KM)
- do a visual check of the differential pressure indicators of the APU generator scavenge filter and the APU lubrication filter.
(1) If the differential pressure indicators do not confirm that the APU generator scavange filter and/or the APU lubrication filter is/are clogged:
- replace the OIL FILTER DIFFERENTIAL PRESSURE SWITCH (8070KM) for the lube pump filter (Ref. AMM TASK 49-91-15-000-001) and (Ref. AMM TASK 49-91-15-400-001).
- replace the OIL FILTER DIFFERENTIAL PRESSURE SWITCH (8071KM) for the gen scav pump filter (Ref. AMM TASK 49-91-14-000-001) and (Ref. AMM TASK 49-91-14-400-001)
(a) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/C11 to the OIL FILTER DIFFERENTIAL PRESSURE SWITCH P9 (lube pump fliter) and P5 (gen scavenge pump filter) (Ref. ASM 49-61/02).
(b) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-001) and (Ref. AMM TASK 49-61-34-400-001).
(2) 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),
(a) If the inspections show that the filter elements has caught: .copper wire particles, .nonmetallic flakes, .phenolic resin.
