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 206/120 affecting Bell 206 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, enacted by the Commonwealth Parliament, aims to ensure the safety and efficiency of civil aviation in Australia. This legislation empowers the Governor-General to create regulations that contribute to the safety of air navigation. One such regulation is found in the Civil Aviation Safety Regulations 1998, where regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory mechanism is integral to maintaining the safety standards of aircraft within Australian airspace, ensuring compliance with international obligations under the Convention on International Civil Aviation. The process of issuing and cancelling ADs is overseen by CASA, reflecting Australia’s commitment to international safety standards and the efficient management of aviation safety concerns.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the regulation of airworthiness in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products. These directives apply to specific types of aircraft or aeronautical products and are intended to address safety concerns that may affect the continuing airworthiness of these items. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design retains responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. In Australia, CASA, as the national airworthiness authority, must assess airworthiness directives issued by the State of Design and, if appropriate, issue Australian ADs to enforce the requirements of the State of Design. The issuance of ADs is a legislative instrument under the Legislative Instruments Act 2003 and is made by CASA in accordance with the Civil Aviation Act 1988. The application of ADs is geographically focused on Australia, with CASA managing the airworthiness of aircraft registered within the country.
Key Provisions
The Civil Aviation Act 1988, under section 98, allows the Governor-General to create regulations aimed at ensuring the safety of air navigation. According to regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This means that CASA has the authority to set rules that must be followed to ensure the safety and airworthiness of aircraft. These directives are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments under the Acts Interpretation Act 1901.
These airworthiness directives are crucial in maintaining the continuing airworthiness of aircraft, a responsibility that falls on both the State of Design and the State of Registry. Under Annex 8 of the Convention on International Civil Aviation, the State of Design, which is the country where the aircraft type was designed, is responsible for providing information necessary for ensuring the continuing airworthiness of that aircraft type. Meanwhile, the State of Registry, which is the country where the individual aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft on its register. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
In a specific case, CASA issued an airworthiness directive (AD/BELL 206/120) affecting Bell 206 model aircraft. After conducting an assessment, CASA cancelled this directive, effective from 23 October 2008. This cancellation was due to the unsafe condition no longer existing, and no replacement AD was required. The cancellation was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, and no consultation with the Australian public was necessary. Additionally, the Office of Best Practice Regulation has determined that such ADs do not require a Regulatory Impact Statement.
The AD was 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. This means that CASA is legally bound to ensure that all directives comply with the safety regulations and that they are issued or cancelled as necessary to maintain the airworthiness of aircraft in Australia. The obligations placed on CASA include the assessment of foreign ADs, the issuance of corresponding Australian ADs when necessary, and the cancellation of ADs when the unsafe conditions they address no longer exist.
Failure to comply with an AD can lead to serious consequences. Under the Civil Aviation Act 1988, any person who fails to comply with an AD can be subject to civil penalties, including fines. In more severe cases, non-compliance can result in criminal penalties, which may include imprisonment. The specific penalties depend on the severity of the breach and the specific provisions of the AD. CASA is responsible for enforcing these directives and taking appropriate action against those who fail to comply with the safety requirements outlined in the ADs.
