4. Fault Isolation_______________
A. If the AUTO LAND operational warning light is mentioned in the log book report: - do the system test of the AFS (Ref. AMM TASK 22-96-00-710-001) and the LAND 3 CAPABILITY test (Ref. AMM TASK 22-97-00-710-001).
R R (1) If these tests are incorrect: - if there is a message, do the trouble shooting procedure related to the maintenance message.
(2) If these tests are correct: - do a check if any RA and/or ILS troubles in the PFR or mentioned in the Log Book.
R R R (a) If yes, do the trouble shooting procedure related to the maintenance message.
(b) If no, no maintenance action is required. But if the fault persist, suspect the AUTOLAND function and notably, troubleshoot consequently the RA and/or ILS systems (antenna, coax, ...) with related bite test and/or operational/functional test if necessary.
