AD/PA-38/26 - Carburettor Air Box Valve - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to ensure the safety of air navigation in Australia, and the Civil Aviation Safety Regulations 1998 provide the framework for implementing this Act. Specifically, regulation 39.001 of these regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thus contributing to the ongoing safety of air navigation. In accordance with the Legislative Instruments Act 2003, ADs are considered legislative instruments. The Civil Aviation Act 1988 and its associated regulations were developed to address the need for stringent and systematic oversight of civil aviation activities, ensuring they meet safety standards both nationally and internationally. The enactment of these regulations and the ability to issue ADs aligns with the overarching policy objective of maintaining the highest safety standards in air navigation. The cancellation of AD/PA-38/26, which affected Piper PA-38 aircraft, has been executed by CASA in alignment with Australia’s commitments under the Convention on International Civil Aviation. The State of Registry is tasked with the responsibility of ensuring the continuing airworthiness of individual aircraft, while the State of Design holds overarching responsibility for the airworthiness of an aircraft type. Given the international nature of aviation, ADs are a crucial mechanism for disseminating necessary information to maintain airworthiness across jurisdictions. The cancellation of this specific AD was enacted by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in compliance with the Act's provisions. This action was taken without public consultation due to Australia's obligations under international conventions, and it does not require a Regulatory Impact Statement.

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, thereby ensuring the safety of air navigation as stipulated under section 98 of the Civil Aviation Act 1988. These directives, as noted in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are recognised as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003. The ADs serve as a means of maintaining the continuing airworthiness of aircraft types, as per Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as responsible for this aspect. Meanwhile, the State of Registry, in this case CASA, is tasked with ensuring the individual aircraft's ongoing airworthiness by adopting or developing appropriate requirements. The recent cancellation of AD/PA-38/26 for Piper PA-38 aircraft by CASA, effective from 18 December 2008, was due to Australia's commitments under the aforementioned Convention, and hence, no public consultation was conducted. The Office of Best Practice Regulation has also determined that such ADs do not necessitate a Regulatory Impact Statement. This AD cancellation was executed by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.

Key Provisions

The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance and management of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs serve as critical instruments for ensuring the continuing airworthiness of aircraft, and under subregulation 39.001(5), they are classified as disallowable instruments under the Acts Interpretation Act 1901, making them legislative instruments. The obligations and requirements imposed by the Act and the Regulations are primarily centred around the continuing airworthiness of aircraft. The State of Design, under Annex 8 of the Convention on International Civil Aviation, bears the responsibility for ensuring the ongoing airworthiness of an aircraft type and must provide necessary information to the appropriate States of Registry. The State of Registry, in turn, is mandated to develop or adopt requirements to maintain the airworthiness of individual aircraft. CASA, as the governing body, issues ADs to facilitate compliance with these standards. Specifically, AD/PA-38/26 was issued for Piper PA-38 aircraft but has since been reviewed and cancelled by CASA, effective from 18 December 2008, without the need for a replacement AD. The Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988 also outline the consequences of non-compliance with ADs. While the specific offences and penalties are not detailed in the provided text, it is clear that failure to adhere to ADs could lead to significant legal ramifications. In general, non-compliance with ADs may result in civil or criminal penalties, as stipulated by the relevant aviation legislation. The maximum penalties for such breaches can be severe, reflecting the critical nature of air safety. The cancellation of AD/PA-38/26 due to Australia's obligations under the Convention on International Civil Aviation underscores the importance of adhering to international standards and the potential repercussions of non-compliance.
