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, 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. When a State of Design issues an AD against a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
The Civil Aviation Safety Authority or its predecessors issued AD/AA-5/18 affecting Gulfstream AA-5 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-5/18. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, aims to ensure the safety and efficiency of civil aviation. Under this Act, the Civil Aviation Safety Regulations 1998 were also enacted, providing a regulatory framework for airworthiness directives. These directives are crucial for maintaining the safety standards of aircraft registered in Australia. The Civil Aviation Safety Authority (CASA), as Australia’s national airworthiness authority, is empowered to issue these directives under regulation 39.001, with the aim of ensuring the continuing airworthiness of aircraft in line with international obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. This approach ensures that Australian-registered aircraft meet global safety standards, thereby protecting the safety of air navigation within Australia and beyond.
Scope and Application
The Civil Aviation Act 1988, as supplemented by 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, ensuring the ongoing safety of air navigation. These directives, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, are aligned with Annex 8 to the Convention on International Civil Aviation. This international framework assigns the State of Design the responsibility for the continuing airworthiness of aircraft types, while the State of Registry must implement or adopt requirements to maintain airworthiness. For aircraft registered in Australia, CASA, as the national airworthiness authority, evaluates ADs issued by the State of Design and, if deemed necessary, issues corresponding Australian ADs. For instance, CASA had previously issued AD/AA-5/18 for Gulfstream AA-5 model aircraft, which was subsequently cancelled on 4 June 2009, due to the elimination of the unsafe condition identified. The cancellation of this AD reflects Australia's commitment to international aviation safety standards without the necessity for public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The key provisions of the Civil Aviation Act 1988, particularly in relation to the issuance of airworthiness directives (ADs), are outlined in section 98, which allows the Governor-General to make regulations for the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific kinds of aircraft or aeronautical products. According to subregulation 39.001(5), ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are considered legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA to issue ADs when necessary to ensure the continuing airworthiness of aircraft registered in Australia. This involves assessing the ADs issued by the State of Design and, if appropriate, issuing corresponding Australian ADs to mandate the requirements of the State of Design. Furthermore, the State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to ensure compliance with these ADs.
Breaches of the regulations concerning ADs can result in significant consequences. Under the Civil Aviation Act 1988, operators who fail to comply with ADs can face both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can include imprisonment, reflecting the serious nature of non-compliance with airworthiness directives. The maximum penalties can vary depending on the specific breach and the discretion of the court. CASA’s enforcement actions aim to ensure that all aviation safety standards are met to protect the public and maintain the safety of air navigation.
