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 206/110 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 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, addressing issues pertinent to the safety, efficiency, and orderly development of aviation. The Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which govern various aspects of civil aviation, including the issuance of airworthiness directives (ADs). These ADs are essential tools for ensuring the continuing airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 mandate that ADs, which are legislative instruments, must be issued by the Civil Aviation Safety Authority (CASA) under the authority of the Act and in accordance with international standards set by the Convention on International Civil Aviation. The Act and its regulations reflect Australia's commitment to maintaining high safety standards in civil aviation, both domestically and in alignment with international obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the legal framework for the issuance and management of airworthiness directives (ADs) in Australia, ensuring the safety of aircraft and aeronautical products. Under the Act, the Governor-General has the authority to make regulations for the purposes of the Act and the safety of air navigation. The Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are designed to address safety issues identified by the State of Design and must be assessed and potentially mandated by CASA as the national airworthiness authority. The scope of these regulations applies to all aircraft registered in Australia, and CASA must ensure compliance with international standards set by the International Civil Aviation Organization (ICAO). The specific AD/BELL 206/110 concerning the Bell 206 model aircraft has been cancelled due to the resolution of the unsafe condition identified, and no further action is required as per the obligations under the Convention on International Civil Aviation.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for the regulation of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations that promote the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specified types of aircraft or aeronautical products. These ADs are considered legislative instruments as they are disallowable under section 46A of the Acts Interpretation Act 1901 and subject to the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA to closely monitor and respond to ADs issued by the State of Design of an aircraft type. Specifically, when an AD is issued by the State of Design concerning a type of aircraft registered in Australia, CASA must evaluate the information provided and, if necessary, issue an Australian AD to enforce the requirements of the original AD. This ensures that Australian-registered aircraft meet the continuing airworthiness standards as mandated by international conventions, particularly Annex 8 to the Convention on International Civil Aviation.
Moreover, the State of Registry, which in this case is Australia through CASA, has the responsibility of ensuring the continuing airworthiness of individual aircraft registered within its territory. This includes developing or adopting requirements necessary to maintain the airworthiness of these aircraft, as outlined in Annex 8. The cancellation of AD/BELL 206/110 affecting Bell 206 model aircraft, which CASA assessed and subsequently cancelled, illustrates the process by which CASA enforces these obligations.
In terms of consequences for non-compliance, the Act does not explicitly detail the specific penalties for breaches related to ADs. However, given the overarching regulatory framework within which these provisions operate, it is reasonable to infer that non-compliance with ADs could result in significant civil or criminal penalties. These might include fines, imprisonment, or both, depending on the severity of the breach and the specific provisions of other relevant legislation, such as the Crimes Act 1914.
