It was likely that, because of the Civil Aviation Safety Authority’s policy at the time, their engineering assessment of the tie rod design for inclusion in the manufacturer’s Australian Parts Manufacturer Approval did not consider the service history of the original tie rods or identify that they were subject to airworthiness directive AD/DH 82/10. Consequently, the assessment team was likely unaware that the original tie rods were subject to a life limitation, and did not require the life limits for the replacement tie rods to be established.

The ATSB provided the Civil Aviation Safety Authority (CASA) with written information about this safety issue on 30 January 2015. A follow-up meeting was held with CASA to discuss the issue further on 11 February 2015.
