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.
Transport Canada has issued AD CF-2007-21 affecting Bell 222 series helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 222/43 which will become effective on 14 September 2007.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, was introduced to establish a legislative framework for the regulation of civil aviation within Australia. This Act aims to ensure the safety of air navigation and to provide for the orderly development of civil aviation. Under this Act, the Civil Aviation Safety Regulations 1998 were also established, which include provisions for the issuance of airworthiness directives (ADs). These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs concerning types of aircraft or aeronautical products, as stated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. The objective of these ADs is to maintain the continuing airworthiness of aircraft, in line with international standards set forth by the Convention on International Civil Aviation, specifically Annex 8, which assigns the State of Design the responsibility for ensuring the continuing airworthiness of aircraft types. CASA, acting as Australia’s national airworthiness authority, is mandated to issue corresponding ADs when necessary, ensuring compliance with international obligations and maintaining safety standards within Australia.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for ensuring the safety of air navigation in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are crucial for maintaining the continuing airworthiness of aircraft and are mandated by international standards under Annex 8 to the Convention on International Civil Aviation. ADs are issued by the State of Design, and Australia, as the State of Registry, is obligated to assess and, if necessary, issue corresponding Australian ADs to ensure compliance with international safety standards. Notably, ADs are considered legislative instruments under the Legislative Instruments Act 2003 and do not require public consultation or a Regulatory Impact Statement. The ADs are implemented by CASA, specifically by the Manager, Systems in the Airworthiness Engineering Branch, in accordance with the Civil Aviation Act 1988. This regulatory approach ensures that Australian aviation remains aligned with global safety standards, while maintaining the necessary oversight and enforcement mechanisms to protect the public.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for airworthiness directives (ADs) in Australia, with particular emphasis on safety and adherence to international standards. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations that support the Act's objectives, particularly in ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for certain types of aircraft or aeronautical products. This regulation further stipulates, under subregulation 39.001(5), that ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and hence, legislative instruments under the Legislative Instruments Act 2003.
The obligations under this legislation require the State of Design to maintain overall responsibility for the continuing airworthiness of an aircraft type, and to provide necessary information to ensure that the aircraft can maintain its airworthiness. This aligns with Annex 8 of the Convention on International Civil Aviation. Correspondingly, the State of Registry, in this case, Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When the State of Design issues an AD, such as the one issued by Transport Canada for the Bell 222 series helicopters, CASA must assess this information and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. This process ensures that Australian aircraft comply with international safety standards.
Failure to comply with ADs can result in serious consequences. The Act and Regulations impose significant obligations on the parties involved, including manufacturers, operators, and CASA. Any breach of these obligations can lead to enforcement actions, including the potential for civil or criminal penalties. While the specific penalties are not detailed in the provided text, it is clear that non-compliance with airworthiness directives can lead to severe repercussions, both legally and in terms of safety. CASA, as the national airworthiness authority, plays a critical role in enforcing these regulations to ensure the highest standards of aviation safety are met across the country.
