4. Fault Isolation
_______________
A. If the POST FLIGHT REPORT gives the maintenance message ADM4 (19FP4)/ ADM6 (19FP6):
- do a visual check of the PROBE-R STATIC, 1 (8DA1) and PROBE-R STATIC, 2 (8DA2).
(1) If the R static probe 1 or R static probe 2 is damaged:
- replace the defective R 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 a 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 and ADM 6) (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).

B. 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).
C. 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).

4. Fault Isolation
_______________
A. If the POST FLIGHT REPORT gives the maintenance message ADM1 (19FP1)/ ADM3 (19FP3):
- do a visual check of the PROBE-PITOT, 1 (9DA1) and PROBE-PITOT, 3 (9DA3).
(1) If the pitot probe 1 (9DA1) or the pitot probe 3 (9DA3) is damaged:
- replace the defective pitot probe (Ref. AMM TASK 34-11-15-000-001) and (Ref. AMM TASK 34-11-15-400-001).
