3. Fault Confirmation
__________________
A. Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-008).
4. Fault Isolation
_______________
A. Maintenance Action
(1) If the APU Last Leg Report gives the maintenance message:
GEN SCAV FILTER (8069KM) AND LUBE FILTER (8076KM) Fault Code Number: 039
- do a visual check of the DIFFERENTIAL PRESSURE INDICATORS of the APU GENERATOR SCAVENGE-FILTER (8069KM) and the APU LUBRICATION FILTER (8076KM).
(a) If the DIFFERENTIAL PRESSURE INDICATORS do not confirm that the APU GENERATOR SCAVENGE-FILTER (8069KM) and/or the APU LUBRICATION FILTER (8076KM) is/are clogged:
- replace the DIFFERENTIAL PRESSURE INDICATOR-SWITCH (8069KM) (Ref. AMM TASK 49-91-21-000-002) and (Ref. AMM TASK 49-91-21-400-002).
(b) If the fault continues:
- replace the DIFFERENTIAL PRESSURE INDICATOR-SWITCH (8076KM) (Ref. AMM TASK 49-91-23-000-001) and (Ref. AMM TASK 49-91-23-400-001).
1 If the fault continues:
_
- do a check and repair the wiring from the ECB (59KD) AB/J2, J4 to the OIL FILTER DELTA P-SWITCH P5/1,2 (Ref. ASM 49-61/02)
a If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-002) and (Ref. AMM TASK 49-61-34-400-002).
(2) If the DIFFERENTIAL PRESSURE INDICATOR confirms that the APU GENERATOR SCAVENGE-FILTER (8069KM) and/or the APU LUBRICATION FILTER (8076KM) is/are clogged:
- replace the oil filter elements (Ref. AMM TASK 49-91-41-920-001) and (Ref. AMM TASK 49-91-41-920-002),
- do an inspection of the removed oil filter elements,
- remove the magnetic drain plug (Ref. AMM TASK 49-91-42-000-002),
- do an inspection of the magnetic drain plug (Ref. AMM TASK 49-91-42-200-003).
(a) If the inspections show that only the element of the generator scavenge filter has caught particles:
- replace the GEN-APU (8XS) (Ref. AMM TASK 24-23-51-000-001) and (Ref. AMM TASK 24-23-51-400-001),

- install the magnetic drain plug (Ref. AMM TASK 49-91-42-400-002),
- change the APU oil (Ref. AMM TASK 49-90-00-600-005),
- start and operate the APU for 5 minutes (Ref. AMM TASK 49-00-00-710-008),
- remove the oil filter elements (Ref. AMM TASK 49-91-41-920-001) and (Ref. AMM TASK 49-91-41-920-002),
- do an inspection of the removed oil filter elements,
- remove the magnetic drain plug (Ref. AMM TASK 49-91-42-000-002),
- do an inspection of the magnetic drain plug (Ref. AMM TASK 49-91-42-200-003).
1 If you do not find contamination:
_
- install the serviceable oil filter elements (Ref. AMM TASK 49-91-41-920-001) and (Ref. AMM TASK 49-91-41-920-002),
- install the magnetic drain plug (Ref. AMM TASK 49-91-42-400-002),
- make an entry in the applicable logbook to tell people the facts of your inspections.
2 If you find contamination:
_
- install the oil filter elements (Ref. AMM TASK 49-91-41-920-001) and (Ref. AMM TASK 49-91-41-920-002),
- install the magnetic drain plug (Ref. AMM TASK 49-91-42-400-002),
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-003) and (Ref. AMM TASK 49-11-11-400-003), 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 机载辅助动力 1(108)
