Failure of the Accelerometers 1 and 2

TASK 27-92-00-810-808-A
Failure of the Accelerometers 1 and 2

1. Possible Causes

ACCLRM-1 [12CE1]
ACCLRM-2 [12CE2]
wiring of the power supply signal from the accelerometer 1 (12CE1) to the first terminal block
wiring of the power supply signal from the accelerometer 2 (12CE2) to the first terminal block

2. Job Set-up Information
A. Referenced Information

REFERENCE	DESIGNATION
AMM 27-92-16-000-001	Removal of the Flight Control Accelerometer
AMM 27-92-16-400-001	Installation of the Flight Control Accelerometer
ASM 279224
AMM 27-96-00-740-001	BITE Test of the EFCS (Ground Scanning)

3. Fault Confirmation
Subtask 27-92-00-740-060-A

A. Test
(1) Do the BITE test of the EFCS (ground scanning) AMM 27-96-00-740-001.

4. Fault Isolation
Subtask 27-92-00-810-057-A

A. If the BITE test gives the maintenance messages:
ACCLRM 1 12CE1
and
ACCLRM 2 12CE2

replace the ACCLRM-1 [12CE1] and the ACCLRM-2 [12CE2] , AMM 27-92-16-000-001 and AMM 27-92-16-400-001.

(1) If the fault continues:

do a check and repair the wiring of the power supply signal from the accelerometer 1 (12CE1) to the first terminal block and the wiring of the power supply signal from the accelerometer 2 (12CE2) to the first terminal block, ASM 279224.

Subtask 27-92-00-740-061-A

B. Do the test given in Para. 3.
