AD/PA-25/1 - Fin Post - Modification - CANCELLED

Overview

The Civil Aviation Act 1988, enacted to ensure the safety and efficiency of civil aviation in Australia, empowers the Governor-General to create regulations necessary for the safety of air navigation. This Act is complemented by the Civil Aviation Safety Regulations 1998, which provide specific regulatory frameworks for airworthiness and safety standards. Under this regulatory framework, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft and aeronautical products, as outlined in regulation 39.001. These directives are instrumental in maintaining the continuing airworthiness of aircraft, aligning with Australia's international obligations under Annex 8 to the Convention on International Civil Aviation. In accordance with these legislative provisions, CASA has issued, reviewed, and subsequently cancelled an airworthiness directive affecting Piper PA-25 aircraft, with the cancellation set to take effect on 20 November 2008. This action was taken to align with Australia’s obligations under the Convention on International Civil Aviation, thereby negating the need for public consultation on the matter. Furthermore, the Office of Best Practice Regulation has concluded that such ADs do not require a Regulatory Impact Statement. The cancellation was executed by the Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in compliance with the statutory requirements outlined in the Civil Aviation Act.

Scope and Application

The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These directives are essential tools for ensuring the ongoing airworthiness of aircraft and are a legislative instrument under the Legislative Instruments Act 2003. The application of these ADs is broad, encompassing all aircraft registered within Australia and operated under Australian jurisdiction, thus affecting aircraft operators, manufacturers, and maintenance providers. Geographically, the application of these ADs extends across the Commonwealth, aligning with Australia’s obligations under the Convention on International Civil Aviation. However, the specific AD/PA-25/1 affecting Piper PA-25 aircraft was issued and subsequently cancelled by CASA, reflecting Australia’s adherence to international obligations and domestic safety standards. The cancellation of this directive, effective from 20 November 2008, did not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. This legislative action was taken by the Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.

Key Provisions

The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations to enhance the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs, which are legislative instruments under subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003, serve as a means to maintain and ensure the continuing airworthiness of aircraft. The State of Design is primarily responsible for overseeing the airworthiness of an aircraft type, in line with Annex 8 of the Convention on International Civil Aviation, and must furnish necessary information to the States of Registry. Conversely, the State of Registry, in this case CASA, is tasked with ensuring the ongoing airworthiness of individual aircraft, as stipulated in Annex 8. Under the Civil Aviation Safety Regulations 1998, CASA is responsible for issuing ADs that provide critical information to maintain the airworthiness of specific aircraft types. This includes the Piper PA-25 aircraft, for which AD/PA-25/1 was issued. However, CASA has subsequently reviewed and cancelled this particular AD, with the cancellation set to take effect on 20 November 2008. This cancellation is a direct consequence of Australia's commitments under the Convention on International Civil Aviation, and as such, there was no requirement for public consultation or the preparation of a Regulatory Impact Statement. The cancellation of AD/PA-25/1 was made by the Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. This process reflects the regulatory authority's adherence to international obligations and domestic legislative requirements, ensuring that the continuing airworthiness of aircraft is maintained through appropriate and timely directives. The cancellation does not necessitate the issuance of a replacement AD, as it aligns with Australia’s responsibilities under international aviation agreements. The legislative framework surrounding airworthiness directives underscores the importance of maintaining stringent safety standards in civil aviation. CASA’s role in issuing and managing these directives is crucial to ensuring that both international and domestic aviation safety standards are upheld. This regulatory approach ensures that aircraft remain airworthy and safe for operation, thereby protecting the interests of passengers, crew, and the public. The outlined process and its adherence to international conventions reflect a comprehensive and collaborative effort to maintain high safety standards in the aviation industry.
