During a maintenance inspection of a Boeing 737-300 aircraft, registered VH-YNU, the failure of a wing spoiler cable was identified. The Civil Aviation Safety Authority (CASA) requested technical assistance from the ATSB in the examination of the cable. To facilitate this assistance, the ATSB initiated an external investigation under the provisions of the Transport Safety Investigation Act 2003.

The ATSB has concluded the examination of the cable, and provided the results of that work to CASA on 6 May 2022.

The Civil Aviation Safety Authority is responsible for and will administer the release of any information from the maintenance inspection. Any enquires relating to the matter should be directed to CASA at
