TASK 30-31-00-810-849-A
Loss of the R Static Probe Output-Discrete from the PHC 2


1. Possible Causes
  • PHC-2 [6DA2]
  • wiring from the PHC 2 (6DA2) to the ADIRU 2 (1FP2)

3. Fault Confirmation
Subtask 30-31-00-710-146-A
A. Test
   (1) Do the operational test of the probe ice protection AMM 30-31-00-710-001.
4. Fault Isolation
Subtask 30-31-00-810-098-A
A. If the test gives the maintenance message CHECK ADIRU2 R STATIC PHC 2 INTERFACE:
  • do a check for ground at pin A/Y of the PHC 2 (6DA2) ASM 303102.
   (1) If there is no ground:
     (a) If the fault continues:
  • do a check and repair the wiring from the PHC 2 (6DA2) to the ADIRU 2 (1FP2) pin A/Y to pin AA/4H ASM 341302.
     (b) If the fault continues:
  • do the INTERFACE TEST of the ADR (system 2) AMM 34-13-00-740-002
  • do the necessary corrective actions: (TSM chapter 34).
Subtask 30-31-00-710-147-A
B. Do the operational test given in Para. 3.
