__________________
 A. Test
 (1) Do the operational test of the side stick assembly (Activation for the BITE test) (Ref. AMM TASK 27-96-00-710-020).
 NOTE : Before you start the operational test procedure, release the
____ FLT CTL/ELAC 1, FLT CTL/ELAC 2 and FLT CTL/SEC 2 pushbutton

 Aug 01/03 CES switches (on these pushbutton switches the OFF legends come on).

 

 (2) Do the BITE test of the EFCS (ground scanning) (Ref. AMM TASK 27-96-00-740-001).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message:
 SEC1 MON OR WIRING TO L B ELEV SERVO VLV 34CE3

 - replace the SEC-1 (1CE1) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
 (1) If the fault continues:

 (a) replace the XDCR UNIT-ELEV POS, L (49CE1) (Ref. AMM TASK 27-92-13-000-001) and (Ref. AMM TASK 27-92-13-400-001).

 (2) If the fault continues:

 - replace the servovalve of the servocontrol 34CE3 (Ref. AMM TASK 27-34-51-000-008) and (Ref. AMM TASK 27-34-51-400-003).

 (3) If the fault continues:

 (a) Replace the SERVO CTL-L ELEVATOR, OUTBD B (34CE3) (Ref. AMM TASK 27-34-51-000-001) and (Ref. AMM TASK 27-34-51-400-001).

 (4) If the fault continues:

 (a) Do a check of the wiring of SV XDCR V1 signal from the servocontrol (34CE3) to the SEC 1 (1CE1) (Ref. ASM 27-94/07):

 - if there is continuity, see Para. (b)

 - if there is no continuity, repair the above wiring.

 

 (b) Do a check of the wiring of the SV XDCR SPLY signal from the servocontrol (34CE3) to the first terminal block (Ref. ASM 27-94/07):

 - if there is continuity, see Para. (c)

 - if there is no continuity, repair the above wiring.

 

 


R (c) Check and repair the wiring of the POS XDCR MON signal from the R transducer unit (49CE1) to the SEC 1 (1CE1) (Ref. ASM 27-94/07):
 B. Do the tests given in Para. 3.
