_______________
A. If the test gives the maintenance message SDAC 1 : RUDDER POS XDCR 42WV:
- do a check for 26VAC at pin A/A of the rudder position transducer unit (42WV) (Ref. ASM 31-54/08).
(1) If there is 26VAC:
- replace the XDCR UNIT-RUDDER POS (42WV) (Ref. AMM TASK 27-25-17-000-001) and (Ref. AMM TASK 27-25-17-400-001).
(2) If there is no 26VAC:
- do a check for a ground signal at pin A/B of the rudder position transducer unit (42WV) (Ref. ASM 31-54/08).
(a) If there is no ground signal:
- repair the wiring between rudder position transducer unit (42WV) pin A/B and the ground terminal (Ref. ASM 31-54/08).
(b) If there is a ground signal:
- do a check of the wiring from rudder position transducer unit (42WV) pin A/A to the first terminal block (Ref. ASM 31-54/08).
