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 New Zealand CAA has issued AD/FU24/177 affecting Pacific Aerospace FU24 aircraft. New Zealand is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/FU24/65, which will become effective on 13 March 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 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 establish a comprehensive legal framework for civil aviation in Australia, focusing on ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations in the interests of air navigation safety. One such regulation is the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for aircraft and aeronautical products. These ADs are legislative instruments and serve as a critical mechanism for maintaining the continuing airworthiness of aircraft, as mandated by international conventions such as Annex 8 to the Convention on International Civil Aviation. Given that ADs are often issued in response to actions by the State of Design, and are intended to align with international standards, CASA must act swiftly to issue corresponding Australian ADs when necessary, without public consultation. This ensures that Australian aircraft meet the requisite safety standards and aligns with Australia's international obligations.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, authorises the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. These regulations empower CASA to mandate ADs for specific types of aircraft or aeronautical products, which are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. ADs serve as the primary means of ensuring the continuing airworthiness of aircraft types and are issued by most International Civil Aviation Organization (ICAO) Contracting States, including Australia. The State of Design has overarching responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to States of Registry, who are then responsible for implementing the required measures. For example, when the New Zealand Civil Aviation Authority issued AD/FU24/177 for Pacific Aerospace FU24 aircraft, CASA assessed the directive and issued Australian AD/FU24/65, effective from 13 March 2008. Given that these ADs are issued in response to international obligations and relevant State of Design directives, there is no requirement for public consultation or a Regulatory Impact Statement. The ADs are made by CASA in accordance with the Civil Aviation Act 1988, ensuring compliance with international standards and obligations.
Key Provisions
The Civil Aviation Act 1988 (the Act) and the Civil Aviation Safety Regulations 1998 (the Regulations) provide a framework for ensuring the safety of air navigation in Australia. Specifically, section 98 of the Act allows the Governor-General to make regulations that are essential for the safety of air navigation, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are legislative instruments, as outlined in subregulation 39.001(5) of the Regulations, and they are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. This means that they can be reviewed and potentially disallowed by Parliament.
Under these provisions, CASA has a duty to assess ADs issued by the State of Design—the country where the aircraft is designed—and to issue corresponding ADs for aircraft registered in Australia, ensuring compliance with international standards. For instance, when New Zealand, as the State of Design for Pacific Aerospace FU24 aircraft, issued AD/FU24/177, CASA assessed this directive and subsequently issued Australian AD/FU24/65. This Australian AD will become effective on 13 March 2008, as stipulated by CASA.
The obligations imposed by the Act and Regulations on CASA and other parties are significant. CASA must ensure that any AD issued by a State of Design is assessed and, if necessary, adopted for aircraft registered in Australia. This includes reviewing the AD to determine if it is applicable to Australian-registered aircraft and ensuring that the necessary safety measures are implemented. The State of Registry, which in Australia is CASA, is responsible for the ongoing airworthiness of individual aircraft. Therefore, when an AD is issued by a State of Design, CASA must act to enforce it through the issuance of a corresponding Australian AD.
Failing to comply with an AD can have serious consequences. Under the Civil Aviation Act 1988, any person who contravenes an AD can be subject to civil penalties, including fines. The maximum penalty for non-compliance with an AD can be substantial, reflecting the importance of adhering to safety regulations. Additionally, continued non-compliance could result in criminal charges, with potential imprisonment, highlighting the serious nature of safety breaches in aviation.
