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/BELL 206/28 affecting Bell 206A model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 2008. 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 a framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations in the interests of safety, including the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs, which are legislative instruments subject to disallowance. The objective of these regulations aligns with Australia’s obligations under the Convention on International Civil Aviation, particularly Annex 8, which assigns responsibility for the continuing airworthiness of aircraft to the State of Design and the State of Registry. CASA, as the national airworthiness authority, must issue Australian ADs when necessary, ensuring compliance with international standards and mitigating risks to aviation safety.
Scope and Application
The Civil Aviation Act 1988, in conjunction with 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, which are regulatory instruments aimed at ensuring the safety of air navigation. These directives are applicable to the aircraft types or aeronautical products specified within the ADs and are intended to mandate compliance with airworthiness requirements established by the State of Design or other relevant authorities. ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and regulation in accordance with the Legislative Instruments Act 2003. The ADs are aligned with the requirements of Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type and mandates that States of Registry develop or adopt requirements to ensure the airworthiness of aircraft registered within their jurisdiction. The application of ADs extends across Australia, and they are issued by CASA in its capacity as the national airworthiness authority, ensuring compliance with international obligations and domestic safety standards. The geographic reach of these regulations is national, applying to all aircraft registered in Australia. Any exclusions or exemptions from the application of ADs would need to be specified within the individual directives themselves, though generally, they apply universally to the specified aircraft types. The Act and Regulations do not provide for any specific exclusions or thresholds that would limit the application of ADs, except as otherwise noted within the directives themselves.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly those relating to the issuance of airworthiness directives (ADs), are crucial for maintaining the safety of air navigation. Section 98 of the Civil Aviation Act 1988 grants the Governor-General the authority to make regulations for the Act, which in this context pertains to air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products. This regulation is further clarified in subregulation 39.001(5), which stipulates that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus are considered legislative instruments according to section 6 of the Legislative Instruments Act 2003.
These regulations impose significant obligations on CASA and other entities involved in aircraft safety. For instance, the State of Design holds the primary responsibility for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. When an AD is issued by the State of Design, CASA, as Australia’s national airworthiness authority, must assess the information and, if deemed appropriate, issue an Australian AD to enforce the requirements. The State of Registry is similarly obligated to develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction.
Failure to comply with the provisions of the Act and the Regulations, including the mandates established through ADs, can result in various consequences. While the text does not explicitly detail the penalties for non-compliance with ADs, it is reasonable to infer that such breaches could lead to civil or criminal sanctions, potentially including fines or imprisonment, given the critical nature of airworthiness directives in ensuring public safety. The issuance and enforcement of ADs are therefore pivotal in maintaining high safety standards in civil aviation.
