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 Transport Canada has issued AD CF-2007-03 affecting Bell 206L model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/170, which will become effective on 8 May 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 Parliament of Australia, governs the safety and regulation of civil aviation within the country. This Act empowers the Governor-General to make regulations for the safety of air navigation. A significant aspect of this Act is the issuance of airworthiness directives (ADs) through the Civil Aviation Safety Regulations 1998, which mandates the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These directives serve as legislative instruments under the Legislative Instruments Act 2003 and are essential for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). This legislative framework ensures that Australia adheres to its international obligations while maintaining stringent safety standards for its aviation industry.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, under section 98 of the Civil Aviation Act 1988, empowers the Governor-General to establish regulations that serve the interests of air navigation safety. Specifically, regulation 39.001 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. Such directives are critical for ensuring the ongoing safety and airworthiness of aircraft and are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, making them legislative instruments as per the Legislative Instruments Act 2003. The application of these directives extends to all aircraft registered within Australia, mandating that the State of Registry, in this case CASA, adheres to international standards set by the State of Design, which, in the case of the Bell 206L model helicopters, is Canada. This jurisdictional reach ensures that Australian civil aviation remains compliant with international agreements such as Annex 8 to the Convention on International Civil Aviation, which allocates responsibilities for continuing airworthiness to the State of Design and the State of Registry. The AD issued by CASA in response to the Transport Canada directive is a direct implementation of these international obligations, and as such, does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, particularly in section 98, grants the Governor-General the authority to make regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning certain types of aircraft or aeronautical products. It is important to note that under subregulation 39.001(5), an AD is considered a disallowable instrument, as per section 46A of the Acts Interpretation Act 1901, and thus constitutes a legislative instrument according to section 6 of the Legislative Instruments Act 2003.
Obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type and provide necessary information to the States of Registry, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design issues an AD, the national airworthiness authority of the State of Registry, such as CASA in Australia, must assess the AD and, if appropriate, issue a corresponding AD to enforce the requirements set forth by the State of Design.
There are no explicit offences or penalties outlined in the text for non-compliance with the ADs. However, the serious nature of airworthiness regulations and the potential risks associated with non-compliance with such directives imply that failure to adhere to ADs could lead to significant safety issues, possibly resulting in severe civil or criminal consequences, including potential aircraft groundings or legal action against the parties responsible for the non-compliance. The text does not specify maximum penalties, but the implications of non-compliance are inherently severe given the critical nature of aviation safety.
