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 2006-0051-E affecting Eurocopter AS 365 N2 and N3 helicopters. EASA is the responsible authority for these helicopter models. CASA has assessed this AD and has issued Australian AD/DAUPHIN/83 which will become effective on 27 February 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 ensure the safety of air navigation, and it empowers the Governor-General to make regulations for this purpose. Under section 98 of this Act, the Civil Aviation Safety Regulations 1998 were established, which include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as legislative instruments under the Acts Interpretation Act 1901 and are essential for maintaining the continuing airworthiness of aircraft types as stipulated in Annex 8 to the Convention on International Civil Aviation. The Act and accompanying regulations reflect Australia's commitment to international aviation safety standards and ensure that the State of Registry maintains the safety of aircraft registered in Australia. The issuance of ADs by CASA is typically in response to directives issued by the State of Design and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides a comprehensive framework for the regulation of aviation safety in Australia. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) to ensure the safety of air navigation. ADs are legislative instruments, subject to disallowance, and are designed to maintain the continuing airworthiness of aircraft registered in Australia. These directives are issued in response to international obligations under the Convention on International Civil Aviation and are typically issued by the State of Design, with CASA then assessing and issuing corresponding Australian ADs when necessary. The ADs do not require public consultation or a Regulatory Impact Statement, and they are issued by designated CASA officers in compliance with the Act. The ADs apply to specific types of aircraft and aeronautical products, and their geographic reach is effectively national, ensuring that Australian-registered aircraft meet international safety standards.
Key Provisions
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for ensuring the safety and continuing airworthiness of aircraft operating within Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations necessary for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs apply to specific kinds of aircraft or aeronautical products and are considered legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the ADs are primarily on CASA, which, as Australia’s national airworthiness authority, must assess any airworthiness information provided by the State of Design and, if necessary, issue Australian ADs to mandate the requirements of the State of Design. This ensures that the continuing airworthiness of aircraft registered in Australia is maintained in accordance with international standards. The State of Registry is also responsible for ensuring the continuing airworthiness of individual aircraft, and must adopt the necessary requirements outlined in any ADs issued by CASA. These obligations are critical in maintaining high safety standards in the aviation sector.
In terms of compliance and enforcement, breaches of the ADs can result in significant consequences. Although the specific penalties for non-compliance are not detailed within the text, it is understood that non-compliance with ADs can lead to serious safety risks and may result in enforcement actions by CASA. These actions can include fines, legal proceedings, and potentially grounding of non-compliant aircraft, which underscores the importance of adhering to the directives. The seriousness of these consequences highlights the critical role that ADs play in maintaining the safety of the aviation industry.
