**ON A/C 001-003, 051-062,
A. If an APU auto shutdown occurs during the operational test of the APU and the APU SHUTDOWNS report gives the maintenance message:
SENSOR FAILURE - BOTH EGT TC RAKES:
- replace the EGT THERMOCOUPLE RAKE 1 and the EGT THERMOCOUPLE RAKE 2 (Ref. AMM TASK 49-72-15-000-001) and (Ref. AMM TASK 49-72-15-400-001).
(1) If the fault continues:
- do a check and repair the wiring from the ECB (59KD) AB/A6, A7 to the EGT THERMOCOUPLE RAKE 1 studs/alumel, chromel (Ref. ASM 49-61/02).
- do a check and repair the wiring from the ECB (59KD) AB/A8, A9 to the EGT THERMOCOUPLE RAKE 2 studs/alumel, chromel (Ref. ASM 49-61/02).
(2) 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).
B. Do the test given in para. 3.
NOTE : It is recommended to make an entry in the applicable logbook that
____ you must read the APU CLASS 3 FAULTS after the first following flight. If the APU CLASS 3 FAULTS page gives the maintenance message EGT TC RAKE 1 after the first following flight:
- do the applicable trouble shooting procedure (Ref. TASK 49-70-00-810-803). If the APU CLASS 3 FAULTS page gives the maintenance message EGT TC RAKE 2 after the first following flight:
- do the applicable trouble shooting procedure (Ref. TASK 49-70-00-810-804).
R **ON A/C 063-099, 401-499,
A. If an APU auto shutdown occurs during the operational test of the APU and the APU SHUTDOWNS report gives the maintenance message:
SENSOR FAILURE - EGT TCPLE RAKES (8057KM1) AND (8057KM2)
with the LRU TROUBLE SHOOT DATA menu information:
BOTH EGT SENSORS FAILED
Fault Code Number: 035
- replace the EGT THERMOCOUPLE RAKE (8057KM1) and the EGT THERMOCOUPLE RAKE (8057KM2) (Ref. AMM TASK 49-72-15-000-003) and (Ref. AMM TASK 49-72-15-400-001). 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 1(12)
