AD/PA-23/62 - Engine Lower Air Scoops and Fairings - Fluid Drainage Provision - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, addressing the need for a comprehensive legal framework to ensure the safety and efficiency of civil aviation. This Act empowers the Governor-General to make regulations, including those related to the safety of air navigation, thereby facilitating the oversight and management of civil aviation activities. In this context, the Civil Aviation Safety Regulations 1998 were introduced to complement the Act, establishing a regulatory environment that ensures the continuing airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Authority (CASA) is mandated under these regulations to issue airworthiness directives (ADs), which serve as crucial tools for maintaining safety standards. These ADs, as legislative instruments, are subject to disallowance under the Acts Interpretation Act 1901 and must comply with the Legislative Instruments Act 2003. The cancellation of AD/PA-23/62, affecting Piper PA-23 aircraft equipped with Airesearch turbochargers, reflects CASA's adherence to international obligations under the Convention on International Civil Aviation, specifically Annex 8, which assigns responsibility for continuing airworthiness to the State of Design and the State of Registry. This cancellation, effective from 12 February 2009, was made by CASA without public consultation as mandated by the Office of Best Practice Regulation, which determined that such ADs do not require a Regulatory Impact Statement. The decision to cancel the AD underscores CASA's commitment to maintaining safety standards in line with international conventions and national regulatory requirements.

Scope and Application

The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) in Australia. These regulations apply to all aircraft and aeronautical products within Australia, with CASA having the authority to issue ADs to ensure the safety of air navigation. The ADs are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, and they serve as a means for the State of Registry to ensure the continuing airworthiness of aircraft, in line with the requirements set out in Annex 8 to the Convention on International Civil Aviation. The scope of these regulations is national, ensuring that both domestic and international standards of aircraft safety are maintained. There are no specific exclusions or exemptions mentioned in the context of these ADs, and the issuance or cancellation of these directives is conducted in accordance with the obligations under the Convention on International Civil Aviation, without the need for public consultation or a Regulatory Impact Statement.

Key Provisions

The Civil Aviation Act 1988 (section 98) empowers the Governor-General to enact regulations that serve the interests of air navigation safety. Under this authority, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are significant instruments for maintaining the continuing airworthiness of aircraft and are legally recognised as disallowable instruments under section 46A of the Acts Interpretation Act 1901. Furthermore, they are classified as legislative instruments under section 6 of the Legislative Instruments Act 2003. The obligations imposed by these regulations are multifaceted. Primarily, the State of Design, which is the country where the aircraft type is designed, bears the responsibility for the aircraft's continuing airworthiness. This includes providing necessary information to the States of Registry, which are the countries where individual aircraft are registered, to ensure compliance with safety standards. The State of Registry must then develop or adopt specific requirements to maintain the airworthiness of aircraft within its jurisdiction. This regulatory framework ensures that both design and registry states collaborate to uphold international safety standards. The Civil Aviation Safety Regulations 1998 include specific examples of regulatory action. For instance, CASA or its predecessors had issued AD/PA-23/62, which pertained to Piper PA-23 aircraft equipped with Airesearch turbochargers. Following a review, CASA decided to cancel this directive, effective from 12 February 2009, without the need for a replacement AD. This cancellation aligns with Australia's commitments under the Convention on International Civil Aviation and does not require consultation with the public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The cancellation was authorised by the Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Non-compliance with the Civil Aviation Act 1988 or the associated regulations can lead to various consequences. While specific offences and penalties are not detailed in the provided text, breaches of airworthiness directives generally carry substantial penalties. These can include fines, imprisonment, or both, depending on the severity of the breach and the specific regulations involved. The overarching aim of these penalties is to ensure strict adherence to safety standards and to protect the public from potential hazards arising from non-compliant aircraft.
