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/ROCK-114/9 affecting Gulfstream (Rockwell) 114 and 114A model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/ROCK-114/9. The cancellation will become effective on 25 September 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 comprehensive legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. This legislation empowers the Governor-General to create regulations in the interests of air navigation safety, with the Civil Aviation Safety Regulations 1998 being one of the key regulatory instruments. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft or aeronautical products, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. These ADs are essential for maintaining the continuing airworthiness of aircraft as mandated by Annex 8 of the Convention on International Civil Aviation, where the State of Design holds responsibility for providing necessary information to the States of Registry. CASA, as Australia's national airworthiness authority, must issue corresponding Australian ADs when required by international obligations, ensuring compliance with both domestic and international safety standards.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia, overseen by the Civil Aviation Safety Authority (CASA). These regulations empower CASA to issue ADs for specific types of aircraft or aeronautical products, which are integral to ensuring the continuing airworthiness of aircraft registered in Australia. These ADs serve as a crucial mechanism to address safety concerns identified by the State of Design or other regulatory authorities, and mandate compliance with specific safety standards. This regulatory approach is in line with Australia's obligations under Annex 8 to the Convention on International Civil Aviation, where the State of Design retains overall responsibility for the continuing airworthiness of an aircraft type. CASA's role as Australia's national airworthiness authority includes assessing and, if necessary, issuing Australian ADs to enforce these safety measures. The ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and are subject to the requirements of the Legislative Instruments Act 2003. The application of these regulations is national in scope, with CASA's authority extending across all aircraft registered in Australia. The issuance of ADs is typically governed by international standards and does not require public consultation or a Regulatory Impact Statement, reflecting the specialised nature of aviation safety regulations.
Key Provisions
The Civil Aviation Safety Regulations 1998 (sections 39.001 and 39.001(5)) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs are legislative instruments and serve to ensure the continuing airworthiness of aircraft types as required under Annex 8 of the Convention on International Civil Aviation. The State of Design holds the primary responsibility for ensuring the airworthiness of an aircraft type, and must provide necessary information to the State of Registry, which then implements the required measures. In the case of Australian registered aircraft, CASA must assess any international ADs and, if necessary, issue corresponding Australian ADs to mandate the required actions.
The obligations imposed by these provisions include the requirement for CASA to assess the airworthiness directives issued by the State of Design and determine if an Australian AD is necessary. CASA must ensure that the information provided by the State of Design is adequate and that the corresponding Australian AD, if issued, effectively mandates the required safety measures. Additionally, the State of Registry is responsible for implementing the requirements set out in the ADs to maintain the continuing airworthiness of aircraft registered within its jurisdiction.
Breach of the requirements set out in an AD may result in civil or criminal consequences. While the specific penalties are not detailed in the text, it is likely that non-compliance with an AD could lead to severe consequences, including fines, imprisonment, or both, under the broader provisions of the Civil Aviation Act 1988 and related regulations. Failure to adhere to ADs can compromise the safety of air navigation and potentially lead to aircraft being grounded or operations being suspended until compliance is achieved.
Under the Acts Interpretation Act 1901, ADs are considered disallowable instruments, meaning they can be reviewed and potentially disallowed by Parliament. This oversight mechanism ensures that the regulations remain within the legislative intent and do not exceed the powers granted by the Civil Aviation Act 1988. Furthermore, although the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, the process for issuing and cancelling ADs is rigorous, reflecting the importance of maintaining high safety standards in aviation.
