A. Test
(1) Do the bite test of the LGCIU identified on the post flight report, (Ref. AMM TASK 32-69-00-740-001).
4. Fault Isolation
_______________
A. Procedure
(1) If the BITE test result shows a fault message:
(a) Swop the LGCIU-1 and LGCIU-2, (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).
(2) If the fault moves to the other LGCIU position:
(a) Swop the LGCIU-1 and LGCIU-2 back and replace the defective LGCIU-1 (5GA1) or LGCIU-2 (5GA2), (Ref. AMM TASK 32-31-71-000-001) and (Ref. AMM TASK 32-31-71-400-001).

(3) If the fault does not move to the other LGCIU position, or TEST OK is shown:
(a) Get access to the SYSTEM REPORT/TEST/L/G page. Use the procedure (Ref. AMM TASK 31-32-00-860-009).
(b) On the MCDU at the LGCIU main menu, press the TROUBLE SHOOT DATA line key.
(c) Make a note of any fault code(s).
(d) Trouble shoot any fault code shown that occurred on the last flight, (Ref. P.Block 301), if the fault code refers to this task, replace the applicable LGCIU. Ref. Para. (2).
R (4) Make sure that the serviceable LGCIU is installed in its initial R postion.

__________________
A. Message Analysis
(1) Examine the Post Flight Report (PFR) to find the flight-phase and
time-difference of the reported faults. R - if the LGCIU-1 and LGCIU-2 faults occurred during different flight R phases, do the trouble shooting procedures related to the R maintenance messages.
- if the LGCIU-1 and LGCIU-2 faults occurred at the same time, do the fault isolation procedure in Para. 4.A.

B. Procedure
(1) Open the C/B 2GA. This will isolate LGCIU2.
(2) Open the C/Bs 1GA and 52GA for 3 seconds and then close them. This will cause the LGCIU1 to do a power-up BITE test.
(a) Wait 60 seconds.
(3) Do a check of the UPPER ECAM and STATUS pages and check that the fault warnings go: 中国航空网 www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：A320 Trouble Shooting Manual 排故手册 起落架 LANDING GEAR 1(6)
