Consultation open - review of uniquely Australian structural fatigue airworthiness directives

These ADs are legacy requirements issued before 2009, with many dating back to the initial acceptance of aircraft types in Australia. At the time, they were developed using a precautionary approach based on limited fatigue data available. Under today’s regulatory, policy and risk framework, many of these ADs would be unlikely to be issued in their current form.

This consultation represents the first tranche of a broader program of work reviewing legacy unique Australian ADs affecting GA aircraft. Subject to consultation outcomes and finalisation, additional uniquely Australian ADs will be considered in future tranches using the policy framework outlined in this consultation package.

This works forms part of our General Aviation Workplan and aims to reduce unnecessary regulatory duplication while maintaining aviation safety.

What we are consulting on

We are seeking feedback on the:

• potential repeal of 18 uniquely Australian structural fatigue ADs
• the policy framework we are using to assess whether such ADs remain appropriate, justified and proportionate
• a proposed CASA direction that aims to formalise existing continuing airworthiness responsibilities for ageing aircraft used in air transport operations.

Safety and responsibilities

Safety remains our highest priority. Regardless of the outcome of this review, owners and operators continue to be responsible for continuing airworthiness, including compliance with manufacturer instructions, applicable State of Design ADs, and CASA maintenance and operational requirements. The removal of these ADs would not reduce these obligations.

Have your say

We encourage you to provide feedback on safety, operational impacts, and potential alternative risk mitigations. Your feedback will help inform our assessment and next steps.
