3. Fault Confirmation
__________________
A. Check/Test
(1) Do the operational test of the APU (Ref. AMM TASK 49-00-00-710-008). NOTE : Make sure that the fuel supply to the APU is correct (Ref. AMM
____ TASK 28-22-00-710-002). If the fuel supply is not correct, do the trouble shooting of APU low fuel pressure (Ref. TASK 28-22-00-810-801).
NOTE : During the operational test of the APU, carefully examine the
____ fuel lines from the fuel control unit to the inlet guide-vane actuator:
- fuel leaks are not permitted, correct/replace as necessary.
4. Fault Isolation
_______________
A. Maintenance Action
(1) If the APU Last Leg Report gives the maintenance message:
IGV ACTR (8014KM)
Fault Code Number: 098
NOTE : The APU SHUTDOWNS report gives the maintenance message:
____ OVERTEMPERATURE - IGV ACTR (8014KM) APU Auto Shut Down Fault Code Number: 098
- do the push/pull test of the IGV mechanism (Ref. AMM TASK 49-23-51-710-001).
(a) If the push/pull test fails:
- 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(103)
