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-2005-05 affecting Bombardier CL-600 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/CL-600/75, which will become effective on 02 August 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to provide a legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations necessary for achieving this objective. Complementing the Act, the Civil Aviation Safety Regulations 1998, also created under the authority of the Australian Parliament, include provisions for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives serve as a crucial mechanism for maintaining the airworthiness of aircraft in accordance with international standards, particularly those set by the International Civil Aviation Organization (ICAO). This legislative framework is designed to ensure that Australia meets its international obligations under the Convention on International Civil Aviation, while also safeguarding the safety of Australian airspace.
Scope and Application
The Civil Aviation Act 1988 applies broadly to ensure the safety of air navigation and is supported by the Civil Aviation Safety Regulations 1998. Specifically, regulation 39.001 of these regulations empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, which are deemed legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory framework is essential for maintaining the continuing airworthiness of aircraft, a responsibility that is shared between the State of Design and the State of Registry as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, must respond to ADs issued by States of Design, such as Transport Canada's AD CF-2005-05 for Bombardier CL-600 model aircraft, by issuing corresponding Australian ADs. The issuance of such directives is mandated by Australia's international obligations and does not require public consultation or a Regulatory Impact Statement. The ADs are issued under the authority of the Act, specifically subsection 84A(2), by designated CASA officials in the Manufacturing, Certification and New Technologies Office.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations that are in line with the Act and serve the interests of air navigation safety. This overarching authority enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. According to subregulation 39.001(5), these ADs are classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. ADs are integral to ensuring the continuing airworthiness of aircraft, as they provide necessary information to maintain safety standards.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 on the parties involved are quite significant. The State of Design, which is the country where the aircraft is designed, has the primary responsibility for the continuing airworthiness of the aircraft type. This includes providing any necessary information to the States of Registry, which are the countries where the aircraft are registered, to ensure airworthiness. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, is obligated to assess this information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design.
There are specific consequences for non-compliance with the provisions set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. While the text does not detail specific offences or penalties for breaches of ADs, it is reasonable to infer that non-compliance with ADs could lead to serious safety issues and potential regulatory action. In Australia, CASA enforces compliance through various means, which could include administrative actions, fines, or other penalties as stipulated in relevant aviation regulations. The seriousness of airworthiness issues means that breaches can have severe implications, including grounding of aircraft, legal action, and significant financial penalties. It is clear that the provisions are designed to ensure the highest standards of safety in civil aviation.
