Loss of the Two Sensing Elements of the Exchanger Outlet Temperature-Sensor of the Engine 1


TASK 36-11-00-810-827-A
Loss of the Two Sensing Elements of the Exchanger Outlet Temperature-Sensor of the Engine 1


1. Possible Causes
  • SENSOR-EXCHANGER OUT TEMP, ENG 1 [6HA1]
  • wiring between pin A/1 of the exchanger outlet temperature-sensor (6HA1) and th ground terminal
  • wiring from the exchanger outlet temperature-sensor (6HA1) to the BMC1 (1HA1)
  • wiring from the exchanger outlet temperature-sensor (6HA1) to the BMC2 (1HA2)
  • BMC-1 [1HA1]
  • BMC-2 [1HA2]

3. Fault Confirmation
Subtask 36-11-00-710-106-A ** ON A/C NOT FOR ALL
A. Test.
   (1) Not applicable, the fault is evident.
4. Fault Isolation
Subtask 36-11-00-810-079-A ** ON A/C NOT FOR ALL
A. If the fault symptom is identified by the maintenance message:
TEMP SENSOR 6HA1
   (1) If the fault continues:
  • do a check for ground at pin A/1 of the exchanger outlet temperature-sensor (6HA1).
     (a) If there is no ground:
  • do a check and repair the wiring between pin A/1 of the exchanger outlet temperature-sensor (6HA1) and th ground terminal ASM 361101.
     (b) If there is ground:
  • do a check and repair the wiring from the exchanger outlet temperature-sensor (6HA1) to the BMC1 (1HA1), pins A/2 and A/4 to pins AA/9B and AA/10B
  • do a check and repair the wiring from the exchanger outlet temperature-sensor (6HA1) to the BMC2 (1HA2), pins A/4 and A/5 to pins AA/6D and AA/7D ASM 361102.
   (2) If the fault continues:
Subtask 36-11-00-710-107-A ** ON A/C NOT FOR ALL
B. After the subsequent flight, make sure that the fault does not continue.
