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 2008-17-15 affecting Boeing 737 model aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/345, which will become effective on 18 December 2008.
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 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, enacted by the Commonwealth Parliament, serves to regulate civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for this purpose, with the overarching goal of safeguarding the public from the inherent risks of air travel. Complementing this, the Civil Aviation Safety Regulations 1998 provide specific mechanisms for maintaining airworthiness, including the issuance of airworthiness directives (ADs). These ADs are legislative instruments that mandate safety improvements or operational limitations on specific aircraft or aeronautical products, reflecting the State of Design's responsibility for the continuing airworthiness of aircraft types and the State of Registry's duty to enforce these requirements domestically. Such directives are integral to upholding international aviation safety standards as set out by the Convention on International Civil Aviation. In this context, the Civil Aviation Safety Authority (CASA) acts as Australia's national airworthiness authority, assessing and implementing ADs issued by other states, such as the United States Federal Aviation Administration, to ensure compliance with both domestic and international regulations.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Under section 98 of the Act, the Governor-General can make regulations in the interest of safety, and regulation 39.001 specifically empowers CASA to issue ADs for types of aircraft or aeronautical products. These ADs are considered legislative instruments, subject to disallowance and scrutiny as per the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs reflect Australia's commitment to the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design the responsibility for continuing airworthiness and mandates that States of Registry adopt measures to maintain this airworthiness. CASA, as Australia's national airworthiness authority, must issue corresponding Australian ADs when necessary, as demonstrated in the case of the Boeing 737 model aircraft affected by the United States FAA AD 2008-17-15. This process underscores the international cooperation and regulatory alignment essential for maintaining global aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, outlines the legal framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Safety Regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. This regulatory power is grounded in Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design a primary role in maintaining the continuing airworthiness of aircraft types and mandates that it provide necessary information to the State of Registry. This means that the country where the aircraft was designed has a duty to ensure it meets international safety standards, while the country where the aircraft is registered must enforce these standards.
Under these regulations, CASA, as Australia’s national airworthiness authority, must review any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the same safety requirements. For instance, the United States, as the State of Design for Boeing 737 model aircraft, issued AD 2008-17-15. CASA assessed this directive and subsequently issued Australian AD/B737/345, which is set to take effect on 18 December 2008. This process ensures that Australian-registered aircraft adhere to internationally recognised safety standards.
The Act imposes specific obligations on CASA and other entities governed by it. CASA must rigorously evaluate ADs issued by the State of Design to determine their applicability to aircraft registered in Australia. If an AD is deemed necessary, CASA must issue an Australian AD to mandate compliance with the safety requirements. This process ensures that Australian-registered aircraft meet international safety standards and that the continuing airworthiness of these aircraft is maintained.
The Civil Aviation Safety Regulations 1998 also establish the legal framework for potential breaches and associated penalties. While the text does not specify detailed penalties for non-compliance with ADs, it is reasonable to infer that failure to comply with an AD could result in severe consequences, including fines or the grounding of aircraft. Such enforcement actions are crucial to maintaining the high safety standards expected in air navigation.
Lastly, the legislation indicates that ADs do not require consultation with the Australian public or a Regulatory Impact Statement, given their basis in international obligations and the technical nature of the directives. This reflects a streamlined process designed to swiftly address safety concerns without unnecessary bureaucratic delays.
