Troubleshooting Recommendations:

  1. Access the system diagnostic in CAIMS and perform the MFS rigging in CAIMS.

    • SYSTEM DIAG
    • 27-00 FLIGHT CONTROLS
    • FLIGHT CONTROL UNIT 2
    • LRU TEST
    • MF SPOILER 1/4 AUTORIGGING
    • CONFIRM
      NOTE: Perform Autorigging test twice to confirm the results. Continue troubleshooting in relation to the results of the test.

    1. If system checks are good, do close out.
    2. If fault remains, continue with next step.

  2. Swap FCU 2 with FCU 1 and reset FCUs latched faults.

    1. If system checks are good, replace FCU 2 and do close out.
    2. If fault remains, continue with next step.

  3. Replace MFS 4 Actuator.
    NOTE: The suspected actuator will now be controlled/rigged by the FCU 1.
  4. Do close out.
