AD/PA-31/91 Amdt 1 - Outboard Flap Track Attachment - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia, ensuring the safety and efficiency of air navigation and operations. This legislation allows for the creation of regulations aimed at maintaining the safety of air navigation, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998 further outline the mechanisms through which CASA can issue such directives. The cancellation of a specific airworthiness directive, AD/PA-31/91 Amdt 1, affecting Piper PA-31 aircraft, exemplifies the practical application of these provisions. The cancellation, effective from 31 July 2008, was made due to Australia’s obligations under the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. The State of Registry is then responsible for ensuring the aircraft's continuing airworthiness, aligning with international standards and practices.

Scope and Application

The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to specific kinds of aircraft or aeronautical products to ensure the safety of air navigation. These ADs, which are legislative instruments, are issued in accordance with Annex 8 of the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness with the State of Design and the State of Registry. In this context, CASA, acting on behalf of Australia as the State of Registry, issued AD/PA-31/91 Amdt 1 affecting Piper PA-31 aircraft, which has since been reviewed and cancelled by CASA. This cancellation is aligned with Australia’s international obligations and has become effective from 31 July 2008. The cancellation of this AD did not require consultation with the Australian public nor a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was issued under the authority of the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with the provisions of the Civil Aviation Act.

Key Provisions

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for airworthiness directives (ADs) in Australia, ensuring the safety of air navigation. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the purposes of the Act, particularly in the interests of safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and hence a legislative instrument according to section 6 of the Legislative Instruments Act 2003. These regulations align with Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness of aircraft types on the State of Design and mandates the provision of necessary information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. The obligations imposed by these provisions are multifaceted. The State of Design must furnish essential information to ensure the ongoing airworthiness of aircraft types, while the State of Registry has the duty to implement measures that maintain the airworthiness of registered aircraft. CASA, acting as the regulatory authority, has the responsibility to issue ADs that address specific safety concerns. The ADs serve as a primary means of continuing airworthiness information, reflecting international standards set by ICAO Contracting States. CASA's authority to issue and subsequently cancel ADs is also clearly outlined, with such actions taken in accordance with the legislative framework and international obligations. Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to significant consequences. While the specific offences, penalties, and consequences for non-compliance are not detailed in the given excerpt, the overarching legislative framework suggests that breaches of these safety regulations could result in both civil and criminal penalties. Civil penalties might include fines, while criminal penalties could involve imprisonment, reflecting the seriousness of ensuring the safety of air navigation. The regulations' alignment with international conventions underscores the importance of compliance, as any failure to adhere to these standards could have broader implications for international air travel safety. In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive regulatory framework for the issuance and management of airworthiness directives in Australia. These provisions ensure that the responsibilities of the State of Design, State of Registry, and CASA are clearly defined, with a focus on maintaining the highest safety standards in air navigation. The legislative measures in place reflect international obligations and are designed to prevent non-compliance through potential civil and criminal penalties.
