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 2009-08-05 affecting Liberty Aerospace XL-2 aircraft. The United States is the State of Design for these aircraft. CASA has assessed this AD and has issued Australian AD/XL/1 which will become effective on 21 April 2009.
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, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to govern civil aviation activities within the country, focusing on safety and regulation. The Act empowers the Governor-General to create regulations that support the Act's objectives, particularly in ensuring the safety of air navigation. A significant regulation under this Act is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are essential for maintaining the airworthiness of aircraft and aeronautical products, thereby ensuring public safety. The issuance of ADs is a critical function of CASA, mandated by international conventions such as Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design responsibility for the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, must act on directives issued by the State of Design, ensuring that Australian ADs align with international standards and obligations.
Scope and Application
The Civil Aviation Act 1988 and associated Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, which are intended to ensure the safety of air navigation. Specifically, under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the purposes of the Act, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, and CASA, as Australia's national airworthiness authority, is mandated to assess and, if necessary, issue Australian ADs to comply with the requirements set forth by the State of Design, which holds the overall responsibility for the continuing airworthiness of an aircraft type under Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA, is responsible for the continuing airworthiness of individual aircraft registered in Australia. In the context of international obligations, when the United States issues an AD affecting aircraft on the Australian Register, CASA must assess and, if appropriate, issue a corresponding Australian AD. This process ensures that Australian aircraft meet international safety standards, as evidenced by the issuance of Australian AD/XL/1 in response to FAA AD 2009-08-05 for Liberty Aerospace XL-2 aircraft. Given the international nature of these directives, no public consultation is required, and the Office of Regulatory Review has determined that such ADs do not necessitate a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the regulation of civil aviation safety in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to make regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are considered legislative instruments under section 46A of the Acts Interpretation Act 1901, and they are issued to maintain or improve the safety of aircraft in operation.
The obligations imposed by these provisions are primarily on CASA, as the national airworthiness authority. CASA must assess any ADs issued by the State of Design, which is the country responsible for the design of the aircraft, to determine if they need to be mandated in Australia. If an AD is deemed necessary, CASA must issue an Australian AD to enforce the safety requirements on aircraft registered in Australia. This process ensures that Australian-registered aircraft meet international safety standards and that the safety of Australian airspace is maintained.
Non-compliance with an AD can lead to significant legal consequences. Under the Civil Aviation Act 1988, failure to comply with an AD can result in civil penalties, including fines. The maximum penalty for each offence can be substantial, reflecting the serious nature of non-compliance with safety directives. In addition to financial penalties, there are also potential criminal consequences for those who deliberately or recklessly ignore an AD, which can lead to imprisonment. These provisions underscore the importance of adhering to ADs to ensure the safety of civil aviation operations.
