R AMM 49-81-00-200-008 Detailed Visual Inspection of the Exhaust V-Clamp and R Portion of Exhaust Duct inside APU Compartment R (131-9(A))
3. Fault Confirmation
__________________
A. Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-010) and do a check on the APU exhaust for oil smoke.
4. Fault Isolation
_______________
A. If there is oil smoke at the exhaust during the operation of the APU: R - disconnect the exhaust muffler from the APU exhaust duct as per Para. R 4.A. of AMM TASK (Ref. AMM TASK 49-81-00-200-008). R - do an inspection of the exhaust cone via the APU exhaust duct for oil R leakage.
R (1) If there is oil at the exhaust:
R - replace the APU AUXILIARY POWER UNIT (4005KM) (Ref. AMM TASK 49-11-R 11-000-004) and (Ref. AMM TASK 49-11-11-400-004).
R (2) If there is no oil at the exhaust:
- replace the Air/Oil Seperator Adapter (Ref. AMM TASK 49-26-54-000-
003) and (Ref. AMM TASK 49-26-54-400-001). R - do the cleaning and testing as given in the Para. 4.B. R
R (a) If the fault continues:
- replace the APU 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
NOTE : 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 49-00-00-860-008),
- 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 49-00-00-860-009),
- 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.

201-210, Config-1 Aug 01/05 CES If no external leak was identified on the APU, do the procedure as given subsequent.
(1) If dirty, clean the APU compartment (Ref. AMM TASK 49-00-00-100-003).
(2) 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).
(3) Do a check and make sure that the flexible seals on the air intake system are in correct condition (Ref. AMM TASK 49-16-00-200-002) and clean.
(4) Do the cleaning of the APU compressors (Ref. AMM TASK 49-20-00-100-004).
(5) Clean the APU bleed air duct, the pneumatic ducts of the aircraft and the environmental control system (Ref. AMM TASK 21-00-00-615-001) or (Ref. AMM TASK 21-00-00-615-002) and (Ref. AMM TASK 21-00-00-100-001). 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(128)
