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 (EASA) has issued AD 2007-0288-E affecting Eurocopter Dauphin model helicopters. EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/DAUPHIN/94, which will become effective on 21 November 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 Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, 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 framework for the regulation of civil aviation in Australia, addressing various aspects of safety, efficiency, and international obligations. The Act empowers the Governor-General to make regulations in the interest of the safety of air navigation, including the issuance of airworthiness directives (ADs) under the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments designed to ensure the continuing airworthiness of aircraft types registered in Australia, aligning with international standards set forth by the International Civil Aviation Organization (ICAO). The Civil Aviation Act 1988 is administered by the Civil Aviation Safety Authority (CASA), which is tasked with assessing and implementing ADs issued by the State of Design or other relevant authorities, as mandated by international agreements such as the Convention on International Civil Aviation. This legislative framework ensures that Australian civil aviation practices remain consistent with global safety standards and that the continuing airworthiness of aircraft is rigorously maintained.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, specifically regulation 39.001, provide the authority for the Civil Aviation Safety Administration (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These directives are essential tools in ensuring the continuing airworthiness of aircraft registered in Australia, aligning with international standards set forth in Annex 8 to the Convention on International Civil Aviation. The ADs are issued in response to continuing airworthiness concerns identified by the State of Design or other relevant aviation authorities, such as the European Aviation Safety Authority (EASA) for Eurocopter Dauphin model helicopters. CASA, as the national airworthiness authority, is obligated to assess and, if necessary, issue corresponding ADs to mandate the requirements of the originating State of Design for aircraft registered in Australia. The application of these regulations is geographically focused on Australian-registered aircraft and aeronautical products, ensuring compliance with international civil aviation standards. This legislative framework does not extend to require public consultation or the preparation of a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation, given the nature and necessity of ADs in maintaining aviation safety.
Key Provisions
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. Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. An AD is a legislative instrument, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. This legislative process ensures that ADs are formal, legally binding requirements designed to maintain the airworthiness of aircraft.
Under these provisions, CASA is tasked with assessing the continuing airworthiness of aircraft registered in Australia. This obligation aligns with Annex 8 of the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of an aircraft type on the State of Design and the State of Registry. When the State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate the directive and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design. This ensures that Australian-registered aircraft meet international safety standards.
The issuance of ADs is not subject to public consultation when they are in response to international obligations or ADs issued by the State of Design. This is due to the nature of ADs as continuing airworthiness information, which does not require a Regulatory Impact Statement. The Office of Best Practice Regulation has determined that ADs do not need to undergo the same scrutiny as other legislative instruments. This streamlined process allows CASA to efficiently address safety issues without unnecessary delays.
Failure to comply with an AD can lead to serious consequences. Aircraft that do not meet the requirements of an AD may be deemed unairworthy, potentially leading to enforcement actions by CASA. This could include grounding of the aircraft, fines, and other regulatory penalties. The specific consequences for non-compliance are determined by the severity of the safety issue and the risk posed to aviation safety. CASA’s authority to enforce compliance ensures that ADs are effective in maintaining high safety standards across the Australian aviation industry.
