B. If the test doesn' t confirm the fault and if the maintenance message CHECK LGCIU1 DISC INPUTS was shown after landing gear free-fall extension:
- no maintenance action is necessary.
C. If the BITE test gives the maintenance message:
CHECK LGCIU1 DISC INPUTS R - replace the PROX SNSR-R L/G EXT, SYS 1 (20GA) (Ref. AMM TASK 32-31-73-R 000-001) and (Ref. AMM TASK 32-31-73-400-001).
R (1) If the fault continues:
R - replace the PROX SNSR-L L/G EXT, SYS 1 (21GA) (Ref. AMM TASK 32-31-R 73-000-001) (Ref. AMM TASK 32-31-73-400-001).
R (2) If the fault continues:
R - replace the PROX SNSR-NLG EXT, SYS 1 (24GA) (Ref. AMM TASK 32-31-R 73-000-005) (Ref. AMM TASK 32-31-73-400-005).
R (3) If the fault continues:
R
R - open the circuit breaker (15CE1) on the panel 49VU and the circuit
