CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 Netherlands CAA has issued AD NL-2005-005 affecting Fokker F100 model aircraft. The Netherlands is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/F100/68, which will become effective on 7 July 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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, governs matters pertaining to civil aviation, including the safety and regulation of aircraft and aeronautical products. One of its key objectives is to ensure the safety of air navigation, which is further detailed in the Civil Aviation Safety Regulations 1998. In this context, the Act empowers the Governor-General to make regulations that serve the interests of aviation safety. Under this legislative framework, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) as a legislative instrument, which play a crucial role in maintaining the continuing airworthiness of aircraft as per international standards set by the Convention on International Civil Aviation. This process ensures that Australian aircraft meet safety standards by aligning with directives issued by the aircraft's State of Design, thereby fulfilling Australia's international obligations and ensuring the safety and efficiency of air navigation within its jurisdiction.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These regulations apply to aircraft registered in Australia and are necessary to ensure the safety of air navigation. An AD becomes effective when CASA, as Australia's national airworthiness authority, issues it in response to a directive from the State of Design, which in this case is the Netherlands for the Fokker F100 model aircraft. As ADs are considered legislative instruments, they are subject to disallowance and have been made in accordance with the relevant legislative framework. Given that these directives are issued under Australia's international obligations and in response to directives from the State of Design, they are not subject to public consultation or a Regulatory Impact Statement. Instead, they are developed by CASA's Section Head - Airframes, Airworthiness Standards Branch, Standards Division, ensuring compliance with the relevant statutory provisions.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the framework for the issuance of airworthiness directives (ADs) in Australia. The Governor-General, under section 98, has the authority to make regulations that serve the interests of air navigation safety. Under regulation 39.001, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products. This process is further clarified by subregulation 39.001(5), which designates ADs as disallowable instruments under the Acts Interpretation Act 1901, making them legislative instruments in accordance with the Legislative Instruments Act 2003. The ADs serve as a critical tool for ensuring the continuing airworthiness of aircraft types, as outlined under Annex 8 of the Convention on International Civil Aviation. This Annex stipulates that the State of Design has overarching responsibility for the continuing airworthiness of an aircraft type, including the provision of necessary information to relevant States of Registry.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and the States of Registry are significant. CASA, as Australia’s national airworthiness authority, is required to assess information from the State of Design and, if necessary, issue an Australian AD to enforce the requirements established by the State of Design. This ensures that Australian registered aircraft comply with international airworthiness standards. Similarly, the State of Registry for individual aircraft is mandated to develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within their jurisdiction. This cooperative effort between the State of Design and the State of Registry is essential for maintaining global aviation safety standards.
Failure to comply with the requirements set forth in ADs can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD may result in both civil and criminal penalties. Civil penalties can include fines, while criminal penalties can result in imprisonment. The exact penalties depend on the severity of the breach and are determined by the courts. Additionally, operators who fail to adhere to ADs risk facing operational restrictions or even the grounding of their aircraft, which can have significant financial and safety implications. These stringent measures underscore the importance of strict adherence to airworthiness directives to maintain the safety of air navigation.
