Troubleshooting Recommendations:

  1. Refer to AW300-78-0314 for detail.
  2. Shut engine down.
  3. Remove power to the ECU for the affected engine via circuit breakers. Wait 10 seconds (de-powering ECUs clears the condition).
  4. Re-establish power to the ECU.
  5. Start the engine. Once stabilized at idle, advance throttle and confirm that the engine responds normally to throttle and annunciations indicate no additional engine issues (confirms first channel is OK).
  6. Confirm that the TR deploys correctly and the engine responds normally to throttle in reverse thrust.
  7. Shut engine down.
  8. Restart the engine. Verify that the engine responds normally to throttle and annunciations indicate no additional engine issues. This confirms that the second channel, which had been held to idle, is clear.
  9. Do close out.
