3. Fault Confirmation
__________________
A. Test Do the BITE test of the weather radar (Ref. AMM TASK 34-41-00-740-002).
4. Fault Isolation
_______________
A. If the test gives the maintenance message RA1(2SA1)/WXR1(1SQ1):
- swap the XCVR-RA, 1 (2SA1) and the radio altimeter transceiver 2 (Ref. AMM TASK 34-42-33-000-001) and (Ref. AMM TASK 34-42-33-400-001).
(1) If the fault stops:
- replace the radio altimeter transceiver that you installed on side
2.
(2) If the fault continues:
- replace the XCVR-WEATHER RADAR, 1 (1SQ1) (Ref. AMM TASK 34-41-33-000-004) and (Ref. AMM TASK 34-41-33-400-003).
(a) If the fault continues:
- remove the weather radar transceiver 1
- remove the radio altimeter transceiver 1
- do a check and repair the wiring from the radio altimeter transceiver 1 to the weather radar transceiver 1: from pins AB/2G, 3G to pins AB/1C, 2C (Ref. ASM 34-41/02)
- install the weather radar transceiver 1
- install the radio altimeter transceiver 1.
B. Do the test given in Para. 3.
Loss of the Interface between the Weather Radar Transceiver 1 and the Radio Altimeter Transceiver 2
1. Possible Causes
_______________
- XCVR-RA, 2 (2SA2)
- XCVR-WEATHER RADAR, 1 (1SQ1)
- wiring from the radio altimeter transceiver 2 to the weather radar
