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-2005-34 affecting Bombardier DHC-8 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/103, which will become effective on 27 October 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 the safety and efficiency of air navigation and operations. Under this Act, the Governor-General has the authority to make regulations for the safety of air navigation, and these regulations are integral to maintaining high standards of aviation safety across the country. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions by allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance, and they play a crucial role in ensuring that aircraft meet the required safety standards. The enactment of these regulations addresses the need for a coordinated approach to aviation safety, aligning Australia with international standards and obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products to ensure safety in air navigation. These directives are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs align with international standards under Annex 8 to the Convention on International Civil Aviation, where the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and the State of Registry must implement requirements to maintain airworthiness. CASA, as Australia’s national airworthiness authority, must assess and potentially issue Australian ADs when an AD is issued by a State of Design that impacts aircraft on the Australian Register. For instance, following the issuance of an AD by Transport Canada affecting Bombardier DHC-8 model aircraft, CASA assessed and issued an Australian AD, demonstrating the jurisdictional reach and international alignment of the regulatory framework. The ADs are issued under specific regulatory mandates and do not require public consultation or a Regulatory Impact Statement, reflecting their administrative nature and the urgency of safety-related mandates.
Key Provisions
The Civil Aviation Act 1988 (sections 98) empowers the Governor-General to make regulations for the safety of air navigation, which in turn allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD is a legislative instrument that ensures the continuing airworthiness of aircraft types and aeronautical products, and is subject to disallowance under section 46A of the Acts Interpretation Act 1901. This legislative framework is designed to align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design has overarching responsibility for an aircraft type’s airworthiness and must provide necessary information to the States of Registry.
Under the Act and Regulations, the State of Registry, such as CASA for Australia, is responsible for ensuring the continuing airworthiness of individual aircraft. This obligation includes developing or adopting requirements for compliance with international safety standards. When a State of Design issues an AD for a type of aircraft registered in Australia, CASA must assess the directive and, if appropriate, issue an Australian AD to mandate the State of Design’s requirements. This process ensures that Australian-registered aircraft meet international safety standards and maintain airworthiness.
The obligations imposed by the Act and Regulations extend to ensuring that ADs issued by States of Design are appropriately assessed and implemented in Australia. CASA, as the national airworthiness authority, must rigorously evaluate these directives to maintain safety standards. For example, Transport Canada issued AD CF-2005-34 concerning Bombardier DHC-8 model aircraft. As Canada is the State of Design, CASA assessed this directive and subsequently issued Australian AD/DHC-8/103, which became effective on 27 October 2005. This process ensures that international safety directives are appropriately adapted and implemented in Australia without the need for public consultation or a Regulatory Impact Statement.
The Act also outlines consequences for non-compliance with ADs. Failure to adhere to the requirements of an AD can result in serious safety risks and may lead to enforcement actions by CASA. While the specific offences and penalties for non-compliance are not detailed in the provided text, it is clear that adherence to ADs is mandatory to ensure the continuing airworthiness of aircraft. Non-compliance can result in civil or criminal penalties, although the exact penalties are not specified in this context. The overarching aim of these provisions is to uphold the highest standards of safety in civil aviation, aligning with international obligations and standards.
