Failure of the left Spoiler 3 Position Transducer

TASK 27-60-00-810-826-A
Failure of the left Spoiler 3 Position Transducer

1. Possible Causes
  • SERVO CTL-SPLR3, L B [31CE5]
  • wiring of the POS XDCR SPLY signal from the servo control (31CE5) to the first terminal block
  • wiring of the POS XDCR V1, V2 signals from the servo control (31CE5) to the first terminal block

3. Fault Confirmation
Subtask 27-60-00-700-084-A
A. Test
   (1) Do the operational test of the side stick assembly (activation for BITE test) AMM 27-96-00-710-020.
   (2) Do the BITE test of the EFCS (Ground scanning) AMM 27-96-00-740-001.
     (a) If the ground scanning gives the maintenance message:
L SPLR 3 POS XDCR 31CE5
  • refer to the Para. Fault Isolation.
     (b) If the ground scanning gives the maintenance messages:
L SPLR 3 POS XDCR 31CE5
R SPLR 3 POS XDCR 31CE6
4. Fault Isolation
Subtask 27-60-00-810-075-B
A. If the BITE test gives the maintenance message:
L SPLR 3 POS XDCR 31CE5:
NOTE: The resistance of primary and secondary windings must be between 30 ohms and 500 ohms.
   (1) If the fault continues:
  • do a check and repair the wiring of the POS XDCR SPLY signal from the servo control (31CE5) to the first terminal block, ASM 279402.
   (2) If the fault continues:
  • do a check and repair the wiring of the POS XDCR V1, V2 signals from the servo control (31CE5) to the first terminal block, ASM 279402.
Subtask 27-60-00-700-085-A
B. Do the tests given in Para. 3.
