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 United States FAA has issued AD 2006-03-08 affecting Aero Advantage Vacuum Pumps. The United States is the State of Design for these vacuum pumps. CASA has assessed this AD and has issued Australian AD/INST/54, which will become effective on 8 June 2006.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General is empowered to make regulations in the interest of air navigation safety, with the Civil Aviation Safety Regulations 1998 specifying how these regulations may be implemented. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments that must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The Civil Aviation Act 1988 and accompanying regulations work in tandem with international obligations, such as Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. CASA, as Australia's national airworthiness authority, is mandated to issue Australian ADs in response to those issued by the relevant State of Design, ensuring compliance with international standards and the safety of air navigation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued in Australia. Specifically, section 98 of the Act empowers the Governor-General to make regulations that ensure the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs concerning types of aircraft or aeronautical products. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus qualifies as a legislative instrument under the Legislative Instruments Act 2003. The ADs serve to implement Australia's responsibilities under Annex 8 to the Convention on International Civil Aviation, ensuring the continuing airworthiness of aircraft types. When a State of Design, such as the United States in this case, issues an AD, CASA, as Australia's national airworthiness authority, must evaluate the information and, if necessary, issue an Australian AD to enforce the State of Design's requirements. Exemptions or exclusions from these regulations are not specified in the text, but the process is streamlined to maintain compliance with international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988 provides the legislative framework within which the Civil Aviation Safety Regulations 1998 operate. Under section 98 of the Act, the Governor-General is empowered to make regulations for air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments, as they are disallowable under section 46A of the Acts Interpretation Act 1901 and thus comply with the requirements of the Legislative Instruments Act 2003.
The obligations imposed by these regulations include a responsibility on the State of Design to ensure the continuing airworthiness of an aircraft type and to provide necessary information to States of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When the State of Design issues an AD, CASA, as Australia's national airworthiness authority, must assess this information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements. This is exemplified by the issuance of AD 2006-03-08 by the United States Federal Aviation Administration (FAA) concerning Aero Advantage Vacuum Pumps, which CASA has assessed and issued as Australian AD/INST/54.
The ADs are issued without public consultation due to Australia's obligations under the Convention on International Civil Aviation and in response to ADs raised by the relevant State of Design. The Office of Regulatory Review has determined that such ADs do not require a Regulatory Impact Statement. The AD/INST/54 was made by the Manager, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Failure to comply with an airworthiness directive can lead to serious consequences. Non-compliance with an AD can result in the grounding of an aircraft or aeronautical product, which can lead to civil or criminal penalties. Under the Civil Aviation Act 1988, an aircraft is deemed airworthy if it conforms to its type design and is in condition for safe operation. Any failure to comply with an AD, which is designed to maintain or restore airworthiness, can therefore be seen as a breach of these statutory requirements. The penalties for such breaches can include fines and imprisonment, depending on the severity of the non-compliance and the impact on aviation safety.
