CIVIL AVIATION ACT 1988
CIVIL AVIATION SAFETY REGULATIONS 1998
ISSUE OF AIRWORTHINESS DIRECTIVE
Under section 98 of the Civil Aviation Act 1988, the Governor-General may make regulations for the purposes of the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. Subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 provides that an AD is a disallowable instrument for the purposes of section 46A of the Acts Interpretation Act 1901. Therefore, in accordance with section 6 of the Legislative Instruments Act 2003, an AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most ICAO Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft.
CASA or its predecessors issued AD/PA-31/38 affecting Piper PA-31 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 31 July 2008. No replacement AD is required.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, serves as the primary legislation governing civil aviation in Australia. Its aim is to ensure the safety of air navigation, providing a framework for regulating civil aviation activities. In line with this, the Civil Aviation Safety Regulations 1998, made under the Act, enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. These ADs serve as a critical tool in ensuring the continuing airworthiness of aircraft, aligning with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. Recently, CASA reviewed and subsequently cancelled AD/PA-31/38, which pertained to Piper PA-31 aircraft, effective from 31 July 2008, due to Australia's obligations under the Convention. This cancellation, made in accordance with the Act, does not require consultation with the public or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products, aligning with the overarching aim of ensuring the safety of air navigation as per section 98 of the Civil Aviation Act 1988. This legislative framework enables CASA to mandate necessary actions to maintain the airworthiness of aircraft, which is critical for the safety of passengers and crew alike. The application of these directives extends to all aircraft and aeronautical products within the Australian jurisdiction, thereby encompassing both domestic and international flights operating within Australian airspace. Importantly, airworthiness directives are classified as disallowable instruments under the Acts Interpretation Act 1901, with their creation and enforcement subject to the oversight provisions outlined in the Legislative Instruments Act 2003. Furthermore, the responsibility for the continuing airworthiness of aircraft falls upon the State of Registry, which must adhere to international standards as stipulated by Annex 8 of the Convention on International Civil Aviation. In the case of the cancellation of AD/PA-31/38 affecting Piper PA-31 aircraft, this decision was made in compliance with Australia's obligations under the Convention, obviating the need for public consultation or a Regulatory Impact Statement.
Key Provisions
Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to establish regulations that are essential for the safety of air navigation. These regulations are crucial as they underpin the legal framework within which airworthiness directives (ADs) are issued. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for specific types of aircraft or aeronautical products. This regulatory mechanism ensures that any identified safety issues are promptly addressed, thereby maintaining high safety standards in the aviation sector. Additionally, subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, further solidifying their legislative standing.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA are significant. CASA is tasked with ensuring the continuing airworthiness of aircraft through the issuance of ADs. This responsibility aligns with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must provide all necessary information to maintain the airworthiness of an aircraft type. Furthermore, the State of Registry, in this case, CASA, must develop or adopt specific requirements to ensure the continuing airworthiness of individual aircraft. This dual responsibility ensures a comprehensive approach to aviation safety, with both the State of Design and the State of Registry playing critical roles. CASA's review and subsequent cancellation of AD/PA-31/38 affecting Piper PA-31 aircraft exemplifies this obligation in action, reflecting a commitment to safety and compliance with international standards.
The implications of breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are serious. Any failure to adhere to ADs or to ensure the airworthiness of aircraft could result in significant safety risks. While specific penalties are not detailed in the provided text, breaches of aviation safety regulations typically carry substantial penalties. These may include fines, imprisonment, or both, depending on the severity of the breach. The overarching goal of these regulations is to maintain the highest possible safety standards, and any non-compliance could have severe consequences, both legally and in terms of public safety. The regulatory framework is designed to enforce strict compliance to prevent accidents and ensure the safety of all persons involved in aviation activities.
