4. Fault Isolation
_______________
A. If the POST FLIGHT REPORT gives the maintenance message ADM5 (19FP5)/ ADM4 (19FP4)/ ADIRU2 (1FP2):
- do a visual check of the static probes.
(1) If one static probe is damaged:
- replace the defective static probe (Ref. AMM TASK 34-11-16-000-001) and (Ref. AMM TASK 34-11-16-400-002).
(2) If the static probes are not damaged:
- do the ADIRS start procedure (Ref. AMM TASK 34-10-00-860-002)
- connect the ARINC Reader to the test connector 198VC on the panel 188VU and to the test connector 199VC on the panel 187VU (Ref. ASM 34-13/01)
- compare the static ADM pressure read on these labels:
(a) If one value is different:
- replace the defective static pressure ADM (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
(b) If the values are the same:
- do the flushing of the static pressure line of the air data module (ADM 4, ADM 5, ADM 6 and ADM 7) (Ref. AMM TASK 34-10-00-170-002)
- do the leak test of the main air data system (CAPT and F/O) (Ref. AMM TASK 34-13-00-790-002).

ADIRU 2 198VC | 19FP6 LABEL 177
pins GG, HH | 19FP7 LABEL 176
B. After the subsequent flight, if the fault continues:
- replace the ADM-L STATIC PRESSURE (19FP5) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
C. After the subsequent flight, if the fault continues:
- replace the ADM-R STATIC PRESSURE (19FP4) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
D. After the subsequent flight, if the fault continues:
- replace the ADM-L STATIC PRESSURE (19FP7) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
E. After the subsequent flight, if the fault continues:
- replace the ADM-R STATIC PRESSURE (19FP6) (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
