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-2007-15 affecting Bell 230 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 222/44, which will become effective on 03 October 2007.
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, Airframes 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 provide for the regulation of civil aviation and to ensure the safety of air navigation. In this context, the Act empowers the Governor-General to make regulations that serve the interests of safety in air navigation, as exemplified by the Civil Aviation Safety Regulations 1998. These regulations enable the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Notably, an AD is considered a legislative instrument under the Legislative Instruments Act 2003, and it can be subject to disallowance under the Acts Interpretation Act 1901. The objective of these regulations aligns with international obligations, particularly under Annex 8 of the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information for the continuing airworthiness of an aircraft type, and the State of Registry must ensure the aircraft's ongoing airworthiness. This legislative framework ensures that CASA, as Australia's national airworthiness authority, can issue Australian ADs in response to directives from the State of Design, thereby maintaining safety standards in accordance with international agreements.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance of airworthiness directives (ADs) in Australia, ensuring the continuing airworthiness of aircraft registered in the country. Under this legislation, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific types of aircraft or aeronautical products, pursuant to regulation 39.001. These ADs, which are legislative instruments, are essential for maintaining the safety standards mandated by international conventions, specifically Annex 8 to the Convention on International Civil Aviation. The Act applies to aircraft registered in Australia and is concerned with the ongoing maintenance of airworthiness, ensuring compliance with both domestic and international aviation safety standards. Geographically, the Act operates under the Commonwealth jurisdiction, with CASA acting as the national airworthiness authority. While the Act primarily focuses on ensuring safety, there are no specific exclusions mentioned within the scope of the ADs issued by CASA, although certain ADs may not require public consultation or a Regulatory Impact Statement if they are direct responses to international directives from the State of Design.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This process is further clarified in subregulation 39.001(5), which states that an AD is a disallowable instrument under the Acts Interpretation Act 1901 and thus constitutes a legislative instrument as per the Legislative Instruments Act 2003.
Obligations under these regulations primarily fall on CASA, the national airworthiness authority of Australia. When an AD is issued by the State of Design—the country responsible for the design of an aircraft type—CASA is required to assess the AD and, if deemed necessary, issue a corresponding Australian AD. This obligation ensures that Australian registered aircraft meet the continuing airworthiness standards mandated by the State of Design. For instance, Canada, as the State of Design for Bell 230 model helicopters, issued AD CF-2007-15, which CASA assessed and subsequently issued as Australian AD/BELL 222/44, effective from 3 October 2007.
The Civil Aviation Safety Regulations 1998 also impose specific procedural requirements on CASA. For example, because ADs are issued in response to international obligations under the Convention on International Civil Aviation and the State of Design's ADs, CASA is not required to consult the Australian public on such directives. Additionally, the Office of Best Practice Regulation has determined that these ADs do not necessitate a Regulatory Impact Statement. This streamlined process ensures that necessary safety measures are communicated and enforced without unnecessary delays.
In terms of consequences for non-compliance, the regulations do not explicitly outline specific penalties within the provided text. However, non-compliance with ADs can lead to significant civil and criminal consequences. Civil penalties can include fines, while criminal penalties can result in imprisonment, reflecting the seriousness of ensuring airworthiness and safety in aviation. CASA's authority to enforce these directives is crucial in maintaining the high safety standards required in the aviation industry.
