(3) Replace the initial LGCIU-1 (5GA1) or LGCIU-2 (5GA2), (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
(4) Make sure that the serviceable LGCIU is installed in its initial position.
(5) Do the test given in Para 3:
- if the fault continues, do the step at Para. (7).
(6) Replace the CFDIU (1TW), (Ref. AMM TASK 31-32-34-000-001) and (Ref. AMM TASK 31-32-34-400-001).
(7) Do the test given in Para. 3.
- if the fault continues, do the next step.
(8) Do a check of the aircraft wiring ARINC-comnnection between the LGCIU 1(2) and the CFDIU (Ref. ASM 32-61/02), and repair as necessary.
(9) Do the test given in Para. 3.

__________________
A. Test
(1) Do the EIS Start Procedure (Upper and Lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(2) At the ECAM Control Panel set the STS page.
(3) Look at the Status Page for the message LGCIU 1 (2).
- if the message is shown, do the fault isolation procedure in Para.
4.A.
- if the message is not shown, there is no LGCIU 1 (2) fault.
4. Fault Isolation
_______________
A. Procedure
(1) Interchange LGCIU 1 with LGCIU 2, (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
(2) Do the test in Para. 3.A:
- if the fault stays in the initial system (identified in the failure message), do step (5)
- if the fault moves to the opposite system, do the next step.
(3) Replace the unserviceable LGCIU-1 (5GA1) or LGCIU-2 (5GA2).

(4) Make sure that the serviceable LGCIU is installed in its initial position.
(5) Do the test in Para. 3.A:
- if the fault continues do the next step.
(6) Do a check and repair the aircraft wiring between the applicable LGCIU and its related 28 VDC power supply C/B, (Ref. ASM 32-31/03) or (Ref. ASM 32-31/04).
(7) Do the test in Para. 3.A.

L/G - GEAR NOT DOWN Message Caused by Downlock Proximity Switch Fault (14GA thru 19GA)
1. Possible Causes

3. Fault Confirmation
__________________
A. Test
(1) If the ECAM message L/G GEAR NOT DOWN occurs in flight, but is not shown on the Post Flight Report (PFR), there is no test:
- do the fault isolation procedure in Para. 4.A., for the six downlock proximity sensors (14GA thru 19GA).
NOTE : An incorrectly adjusted downlock proximity switch can give the
____ message L/G GEAR NOT DOWN, which can be an intermittent fault. Some intermittent faults are not recorded on the PFR.
