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/FK-P/4 affecting Franklin piston engines. CASA has assessed this AD and as a result has cancelled Australian AD/FK-P/4. The cancellation will become effective on 30 July 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 was enacted to provide for the regulation of civil aviation, including safety, and was introduced to address the need for a comprehensive legislative framework governing the operation of aircraft within Australia. Under the authority granted by this Act, the Civil Aviation Safety Regulations 1998 were also established, providing further detail on safety standards and procedures. One of the key mechanisms through which the Civil Aviation Safety Authority (CASA) ensures the continuing airworthiness of aircraft is through the issuance of airworthiness directives (ADs), as stipulated in regulation 39.001. These ADs, which are legislative instruments under the Acts Interpretation Act 1901, serve as a critical tool for maintaining safety standards in accordance with international obligations under the Convention on International Civil Aviation. CASA has the responsibility to assess and, if necessary, issue Australian ADs in response to directives from the State of Design, ensuring that Australian-registered aircraft meet international safety requirements. The cancellation of Australian AD/FK-P/4, pertaining to Franklin piston engines, exemplifies CASA’s role in monitoring and responding to international safety directives to safeguard the Australian aviation sector.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, ensuring compliance with safety standards. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA can mandate these directives, which are considered legislative instruments as per section 46A of the Acts Interpretation Act 1901. The authority to issue ADs is rooted in Annex 8 of the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of an aircraft type on the State of Design, while the State of Registry is tasked with ensuring the continuing airworthiness of individual aircraft. When a State of Design issues an AD affecting aircraft registered in Australia, CASA must review and, if necessary, issue an Australian AD to enforce the requirements. This process was exemplified by the cancellation of Australian AD/FK-P/4 concerning Franklin piston engines, reflecting Australia’s commitment to international aviation safety standards. This action was taken without public consultation, as the Office of Best Practice Regulation has deemed ADs to not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety of air navigation. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations that are in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments according to section 46A of the Acts Interpretation Act 1901.
The obligations under this legislation require CASA to act when an AD is issued by the State of Design of an aircraft type that is registered in Australia. Under Annex 8 to the Convention on International Civil Aviation, the State of Design has a responsibility to ensure the continuing airworthiness of aircraft types and must provide necessary information to States of Registry, such as Australia. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of aircraft within its jurisdiction. CASA must therefore assess any ADs issued by States of Design and, if necessary, issue corresponding Australian ADs to mandate the safety requirements. This process ensures that aircraft in Australia meet international safety standards.
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 and penalties are not detailed in the provided text, it is clear that non-compliance with ADs could potentially result in safety risks, leading to civil or criminal liability for individuals or entities involved. CASA’s role in issuing and enforcing ADs underscores the importance of adhering to these regulations to maintain the safety of air navigation. The cancellation of AD/FK-P/4, for instance, was made under the authority granted by the Act, reflecting CASA’s duty to respond to international safety directives.
