3. Fault Confirmation
__________________
A. Test
(1) Check Altitude/Airspeed tolerances (Ref. TSM 34-13-00 P.Block 301)
- if within tolerances, no further actions required.
(2) Visually check that the 2 quick-disconnect couplings of each ADM hose are properly attached to their respective probe.
(3) Reconnect the couplings found disconnected, if any.
NOTE : After the connection,
____
- Make sure that a colored ring is shown on the quick disconnect coupling.
- Pull the connectors to be sure that they are correctly
attached. Perform an ADR SYSTEM TEST (Ref. AMM TASK 34-13-00-740-003). If the test is correct, no further maintenance action is required.
(4) If all the quick-disconnect couplings are found to be properly attached, do the Functional Test of the Altitude and Airspeed Data (Ref. AMM TASK 34-13-00-720-009)
4. Fault Isolation
_______________
A. If the test shows a different altitude value from the ADR1 (compared to the ADR2 and ADR3) or from the ADR2 (compared to the ADR1 and ADR3) :
- do a visual check of the static probes.
R (1) If one static probe is damaged, replace it (Ref. AMM TASK 34-11-16-R 000-001) and (Ref. AMM TASK 34-11-16-400-002).
(2) Make sure that the small wing of the AOA sensor 1 , (2) or/and (3) is not damaged and that the mechanism moves freely.
R (a) If one AOA sensor is damaged, replace it (Ref. AMM TASK 34-11-19-R 000-001) and (Ref. AMM TASK 34-11-19-400-001).

(3) Do the flushing of the static pressure line of the Air Data Module (ADM 19FP4 and 19FP5 or 19FP6 and 19FP7) (Ref. AMM TASK 34-10-00-170-002).
(4) Do the leak test of the main Air Data System (Ref. AMM TASK 34-13-00-790-002).
(5) Do the functional test of the ADM for the CAPT (F/O) circuit (Ref. AMM TASK 34-11-00-720-001).
(a) If one pressure value is different, replace the defective ADM (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
(b) If the pressure values are the same, replace the AOA sensor 1 ,(2) or /and (3) (Ref. AMM TASK 34-11-19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(6) If the fault continues:
- Do a check to make sure that there are no impacts on the fuselage around the AOA sensors, the static probes and the ADMs (Ref. SRM 530011P.BLOCK101).

B. If the test shows a different altitude value from the ADR3 (compared to the ADR1 and the ADR2):
- do a visual check of the static probes.
R (1) If one static probe is damaged, replace it (Ref. AMM TASK 34-11-16-R 000-001) and (Ref. AMM TASK 34-11-16-400-002).
(2) Make sure that the small wing of the AOA3 sensor is not damaged and that the mechanism moves freely.
R (a) If the AOA sensor 3 is damaged, replace it (Ref. AMM TASK 34-11-R 19-000-001) and (Ref. AMM TASK 34-11-19-400-001).
(3) Do the draining and flushing of the standby static and the standby total pressure line of the Air Data Module (19FP8) (Ref. AMM TASK 34-10-00-170-003).
(4) Do the leak test of the standby circuits (Ref. AMM TASK 34-21-00-790-001).
(5) Do the functional test of the ADM for the standby circuit (Ref. AMM TASK 34-11-00-720-001).
(a) If one pressure value is different, replace the defective ADM (Ref. AMM TASK 34-11-17-000-001) and (Ref. AMM TASK 34-11-17-400-001).
