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 Civil Aviation Safety Authority or its predecessors issued AD/AA-1/3 affecting Gulfstream AA-1 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-1/3. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, 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 was enacted to establish a framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation within the country. The Act empowers the Governor-General to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were also enacted, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. This legislative instrument facilitates the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The ADs are essential for maintaining the safety standards and ensuring compliance with international conventions, such as Annex 8 to the Convention on International Civil Aviation, which mandates the State of Design to provide necessary information for continuing airworthiness.
In accordance with the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, CASA has the authority to issue and cancel ADs. Recently, CASA issued a cancellation for AD/AA-1/3 affecting Gulfstream AA-1 model aircraft, which will become effective on 4 June 2009. This cancellation was made due to the resolution of the unsafe condition previously identified, thereby rendering a replacement AD unnecessary. As this action was undertaken to meet Australia's obligations under the Convention on International Civil Aviation, no public consultation was required. Furthermore, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement. The AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in line with the legislative provisions.
Scope and Application
The Civil Aviation Act 1988, through regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003, designed to ensure the safety of air navigation as mandated by the Act. The ADs, which are common forms of continuing airworthiness information, are issued in line with Annex 8 to the Convention on International Civil Aviation, where the State of Design has the overall responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry. The State of Registry is then responsible for ensuring the continuing airworthiness of individual aircraft. The Civil Aviation Safety Authority, acting as Australia’s national airworthiness authority, must assess ADs issued by States of Design and, if appropriate, issue Australian ADs to mandate the requirements of the State of Design. This process ensures compliance with international standards while maintaining the safety and airworthiness of aircraft registered in Australia.
Key Provisions
The primary operative sections relevant to the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 involve the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are legislative instruments as outlined in subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions are significant for both the State of Design and the State of Registry. The State of Design, which is the country where the aircraft was originally designed, holds the primary responsibility for the continuing airworthiness of the aircraft type. This includes providing necessary information to the States of Registry to ensure the safety and compliance of the aircraft. Meanwhile, the State of Registry, in this case, CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When an AD is issued by the State of Design, CASA must assess the information and, if necessary, issue a corresponding Australian AD to enforce the requirements.
Failure to comply with the ADs can result in serious legal and safety consequences. Under the Civil Aviation Act 1988, there are potential civil and criminal penalties for non-compliance with airworthiness directives. Specifically, section 99A outlines that a person who contravenes an AD can be subject to a fine, imprisonment, or both. The exact penalties can vary depending on the nature and severity of the breach, but the Act allows for substantial fines and imprisonment terms to ensure adherence to airworthiness standards.
The Civil Aviation Safety Regulations 1998 further detail the specific processes and requirements for issuing and complying with ADs. These regulations underscore the importance of maintaining the safety and airworthiness of aircraft, and they mandate that CASA, as the national airworthiness authority, must ensure that all aircraft registered in Australia meet the required safety standards. This includes the assessment and implementation of ADs issued by other countries, ensuring a consistent approach to aviation safety across international borders.
