(e) If there is oil leakage in the area of the oil pump assy:
- replace the seals and or the OIL PUMP ASSY as necessary (Ref. AMM TASK 49-91-45-000-003) and (Ref. AMM TASK 49-91-45-400-003).
(f) If there is oil leakage in the area of the APU generator:

(g) If there is oil leakage in the area of the lupe pump filter and/or the generator scavenge filter:
- replace the packing of the related filter housing (Ref. AMM TASK 49-91-41-200-002).
(h) If there is oil leakage at the magnetic chip detector:
- replace the packing of the magnetic chip detector (Ref. AMM TASK 49-91-42-200-004).
(i) If there is oil leakage at the oil-sump drain-plug housing:

(j) If there is oil leakage at the oil level switch/gearbox interface:
- replace the packing of the oil level switch (Ref. AMM TASK 49-93-16-000-003) and (Ref. AMM TASK 49-93-16-400-003).
(k) If there is oil leakage at the de-oil solenoid/gearbox interface:
- replace the packing of the de-oil solenoid (Ref. AMM TASK 49-91-49-000-003) and (Ref. AMM TASK 49-91-49-400-003).
(l) If there is fuel leakage in the area of the fuel control unit:
- replace the seals and or the FUEL CONTROL UNIT (8022KM) as necessary (Ref. AMM TASK 49-32-11-000-003) and (Ref. AMM TASK 49-32-11-400-003).
(m) If there is fuel leakage in the area of the inlet guide-vane actuator:
- replace the seals and/or the fuel lines to the actuator and/or the INLET GUIDE VANE-ACTUATOR (8014KM) as necessary (Ref. AMM TASK 49-23-51-000-004) and (Ref. AMM TASK 49-23-51-400-004).
(2) If you find other unwanted material on the surfaces of the air intake system components:
- identify the material and its source,
(3) If there is no external contamination:
- if the oil level in the oil reservoir is above the FULL mark on the oil sight glas, correct it with the overflow drain tool (Ref. AMM TASK 49-90-00-600-007).
NOTE : If the APU oil reservoir was filled above the FULL mark on the
____ oil sight glass: During APU operation the oil expands which could create an over-filled condition, resulting in leakage and possible oil smell in the cabin.
- remove the APU Bleed-Air Duct Elbow (Ref. AMM TASK 49-11-11-000-004),
- remove the Load Control Valve (8050KM) (Ref. AMM TASK 49-51-51-000-004).
- examine the removed components with a black light lamp and make sure that you do not find signs of contamination.
(a) If there are signs of contamination:
- clean the APU Bleed-Air Duct Elbow and install it (Ref. AMM TASK 49-11-11-400-004),
- clean the Load Control Valve (8050KM) and install it (Ref. AMM TASK 49-51-51-400-004).
1 If the fault continues:
_
- replace the AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-11-000-004) and (Ref. AMM TASK 49-11-11-400-004).

B. Cleaning and Testing
(1) If an external leak was identified on the APU:
- do the repair,
- clean the area,
- start and operate the APU with no bleed air supply and no APU generator load (Ref. AMM TASK 49-00-00-710-010),
- let the APU operate 15 minutes for thermal stabilization,
- do a leak check on the APU with a black light lamp,
- do the APU shutdown (Ref. AMM TASK 49-00-00-710-010),
- immediately after the APU has stopped, examine the area carefully and make sure that there is no leak,
- if there is a leak (the repair was not succesful), do the repair and/or replace as necessary.
- if there is no leak (the repair was successful), continue as given
subsequent. If no external leak was identified on the APU, do the procedure as given subsequent.
(2) If dirty, clean the APU compartment.
(3) If dirty, clean the air intake diverter, the air inlet duct and the air intake diffuser and elbow (Ref. AMM TASK 49-16-00-100-003). 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 2(125)
