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 European Aviation Safety Authority has issued AD 2005-0012 affecting International Aero Engines (IAE) V2500 engines. France, a member of EASA, is the State of Design for this engine. CASA has assessed this AD and has issued Australian AD/V2500/2, which will become effective on 1 September 2005.
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, Airframes 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 comprehensive legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. The Act empowers the Governor-General to make regulations to safeguard air navigation, and these regulations are intended to be consistent with international standards and practices. One such regulation is the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft and aeronautical products. These ADs serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, in alignment with the obligations under the Convention on International Civil Aviation and the responsibilities of the States of Design and Registry. The ADs are legislative instruments and must be issued in response to directives from the relevant State of Design, as in the case of the European Aviation Safety Authority's AD 2005-0012 affecting IAE V2500 engines, for which CASA issued Australian AD/V2500/2. Given the international context and the nature of ADs, they do not typically require public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia. These directives are issued by the Civil Aviation Safety Authority (CASA), as the national airworthiness authority, in response to obligations under the Convention on International Civil Aviation. This regulatory approach ensures that Australia aligns with international standards for air safety and continuing airworthiness of aircraft. The ADs are binding instruments and are considered legislative instruments under the Legislative Instruments Act 2003. The application of ADs extends to all aircraft and aeronautical products registered in Australia, and they are mandated by the State of Design of an aircraft type in consultation with the State of Registry. This means that when an AD is issued by a State of Design, such as France for the IAE V2500 engines, CASA must evaluate the directive and, if necessary, issue an Australian AD to enforce the requirements. Importantly, this process does not involve public consultation or require a Regulatory Impact Statement, as it is governed by international commitments and specific regulatory protocols.
Key Provisions
The Civil Aviation Act 1988, and specifically section 98, empowers the Governor-General to create regulations aimed at enhancing the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning certain types of aircraft or aeronautical products. Under subregulation 39.001(5), an AD is considered a disallowable instrument as per section 46A of the Acts Interpretation Act 1901, and thus it is a legislative instrument according to section 6 of the Legislative Instruments Act 2003.
These ADs are vital tools under Annex 8 of the Convention on International Civil Aviation, ensuring the continuing airworthiness of aircraft. The State of Design, which is the country responsible for the design of the aircraft or engine, holds the primary responsibility for providing necessary information to maintain airworthiness. When an AD is issued by the State of Design, the State of Registry, in this case Australia, must evaluate this information and, if necessary, issue its own AD. This ensures that the requirements set by the State of Design are met within Australia’s jurisdiction. In this instance, CASA, as Australia's national airworthiness authority, has issued Australian AD/V2500/2 in response to AD 2005-0012 issued by the European Aviation Safety Authority concerning International Aero Engines (IAE) V2500 engines.
The obligations imposed by these regulations are clear: CASA must assess any ADs issued by the State of Design and, if necessary, issue corresponding ADs to ensure compliance with international standards. This process underscores the importance of international cooperation in maintaining aviation safety standards. Furthermore, the issuance of an AD without public consultation is justified under the Convention on International Civil Aviation, and the Office of Regulatory Review has determined that such ADs do not require a Regulatory Impact Statement. The AD is ultimately made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office at CASA, in accordance with subsection 84A(2) of the Act.
In terms of consequences, any breach of the requirements set forth in an AD could result in serious safety issues, potentially leading to both civil and criminal liabilities. While the specific penalties are not detailed in the provided text, it is reasonable to infer that non-compliance with ADs could lead to significant sanctions under aviation law, including fines and imprisonment, given the critical nature of ensuring aircraft airworthiness.
