AD/PA-25/4 - Front Spar Attachment Fittings - Modification - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to regulate civil aviation activities within Australia, ensuring the safety of air navigation. Among its provisions, the Act empowers the Governor-General to make regulations for the purposes of the Act, as seen in the Civil Aviation Safety Regulations 1998. These regulations permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, as outlined in regulation 39.001. The ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The policy objective behind these regulations is to ensure the continuing airworthiness of aircraft in accordance with international standards, particularly those set by the Convention on International Civil Aviation, managed by the International Civil Aviation Organization (ICAO). The cancellation of AD/PA-25/4, which affected Piper PA-25 aircraft, exemplifies the application of these regulatory frameworks. CASA, acting on its responsibilities under the Civil Aviation Act 1988, reviewed and subsequently cancelled this AD due to Australia's obligations under the Convention on International Civil Aviation. This action was taken without public consultation as it did not necessitate a Regulatory Impact Statement. The Manager, Airframes and Structures in the Airworthiness Engineering Group, issued the cancellation on behalf of CASA, reflecting adherence to the legislative authority granted under subsection 84A(2) of the Act.

Scope and Application

The Civil Aviation Act 1988 provides a framework for the regulation of air navigation safety in Australia, empowering the Governor-General to make regulations in the interests of safety. Specifically, under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives for specific types of aircraft or aeronautical products. These directives are legislative instruments that play a critical role in ensuring the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case CASA, is responsible for the ongoing maintenance of airworthiness for individual aircraft registered in Australia. The authority to issue these directives is exercised by the Manager, Airframes and Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Although these directives are legislative instruments, they are not subject to the disallowance process, and no public consultation or Regulatory Impact Statement is required for their issuance or cancellation, as they align with Australia’s international obligations under the Convention on International Civil Aviation.

Key Provisions

Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations that serve the Act's purposes and ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures that the necessary measures are in place to maintain the airworthiness of aircraft. Subregulation 39.001(5) further clarifies that an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is classified as a legislative instrument. The obligations imposed by the Act and the Regulations on the parties and entities they govern are significant. The State of Design, which is the country where the aircraft is designed, holds the primary responsibility for the continuing airworthiness of an aircraft type under Annex 8 to the Convention on International Civil Aviation. This includes providing any necessary information to ensure the airworthiness of the aircraft type to the appropriate States of Registry. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. CASA, as the regulator, plays a critical role in issuing and overseeing airworthiness directives to comply with these international obligations and to maintain safety standards. The Act and the Regulations impose serious consequences for any breaches. While the specific offences and penalties are not detailed in the provided text, it is clear that the issuance and enforcement of airworthiness directives are crucial for maintaining aviation safety. Failure to comply with these directives could potentially result in legal repercussions for the aircraft operators, manufacturers, and other relevant parties. The text does not specify the exact penalties but indicates that CASA's authority to issue and cancel ADs is grounded in statutory provisions, which suggests that non-compliance could lead to enforcement actions under the relevant legislative framework. CASA has recently cancelled an airworthiness directive, AD/PA-25/4, affecting Piper PA-25 aircraft. The cancellation will become effective on 20 November 2008, and no replacement AD is required. This action was taken due to Australia's obligations under the Convention on International Civil Aviation. Notably, no public consultation was required for this AD cancellation, as determined by the Office of Best Practice Regulation, which found that ADs do not necessitate a Regulatory Impact Statement. The AD 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 Civil Aviation Act 1988.
