__________________
A. Test
(1) Do the fan test of the radio altimeter (Ref. AMM TASK 34-42-00-750-001).
4. Fault Isolation
_______________
A. If the fan does not operate correctly:
- replace the XCVR-RA, 2 (2SA2) (Ref. AMM TASK 34-42-33-000-001) and (Ref. AMM TASK 34-42-33-400-001).
(1) If the fault continues:
- replace the FAN-RA XCVR 2 (3SA2) (Ref. AMM TASK 34-42-45-000-001) and (Ref. AMM TASK 34-42-45-400-001).
(a) If the fault continues:
- do a check and repair the wiring between the fan of the RA transceiver 2 (3SA2) and the RA transceiver 2 (2SA2) (Ref. ASM 34-42/02).
