EASA AD GA8-10
Time Limits / Maintenance Checks - Airworthiness Limitations Section - Amendment
Summary
The Commonwealth of Australia Civil Aviation Safety Authority Airworthiness Directive AD/GA8/10 Airworthiness Limitations Section - Service 21/2018 Manual Chapter 4 - Amendment applies to all models of GippsAero GA8 and GA8-TC 320 aeroplanes. It mandates updates to the Airworthiness Limitations Section in the aircraft service manuals to reflect changes approved by CASA. These updates address revised life limitations for specific fuselage strut pick up ribs.
What Changed
This airworthiness directive requires replacing various versions of Chapter 4 Airworthiness Limitations documents in the GippsAero GA8 and GA8-TC 320 service manuals with amendments dated 15 May 2018. The changes reflect a manufacturer design update to fuselage strut pick up ribs number 5 and 6, which have different life limitations than previous designs. The directive applies to multiple service manual amendment versions, including FAA versions.
Why It Matters
Compliance with these updated airworthiness limitations is mandatory in Australia to prevent unsafe conditions caused by exceeding component life limits. Operators, maintenance organizations, and compliance teams must ensure that the revised service manual chapters are incorporated to maintain aircraft airworthiness. Failure to comply could lead to structural failures or regulatory non-compliance.
What To Do
Affected operators must replace the specified Chapter 4 Airworthiness Limitations documents in their service manuals with the amendments dated 15 May 2018 before reaching the life limits specified in the updated documents. This replacement must be completed unless already done, and the directive becomes effective from 31 October 2018. Operators should also consider the applicability of related service bulletins if aircraft have been modified.
