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/CESSNA 500/13 affecting Cessna 500 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 500/13. The cancellation will become effective on 25 September 2008. 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 provide a legislative framework for the safety and regulation of civil aviation in Australia. This Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation, reflecting the need for a robust and reliable civil aviation system. Under the Act, the Civil Aviation Safety Regulations 1998 were established to further detail the regulatory requirements for aviation safety, including the issuance of airworthiness directives (ADs). Regulation 39.001 of these Safety Regulations allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments as per the Legislative Instruments Act 2003 and are subject to disallowance under the Acts Interpretation Act 1901. The objective of these regulations and the issuance of ADs is to ensure the continuing airworthiness of aircraft, in line with Australia’s commitments under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 provides the framework for the regulation of air safety in Australia, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing airworthiness of aircraft registered in Australia. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs serve to implement international obligations under Annex 8 to the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of aircraft types with the State of Design and the State of Registry. In the case of aircraft registered in Australia, CASA must assess the ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to mandate the required safety measures. This process ensures that Australian-registered aircraft meet the necessary safety standards as per international conventions.
Key Provisions
The Civil Aviation Act 1988, specifically section 98, empowers the Governor-General to create regulations that serve the Act's objectives and the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. Furthermore, Annex 8 to the Convention on International Civil Aviation mandates that the State of Design, which is the country where an aircraft type is designed, bears the responsibility for ensuring the continuing airworthiness of that aircraft type and must furnish necessary information to the appropriate States of Registry.
Under the Civil Aviation Safety Regulations 1998, CASA has the authority to issue ADs that mandate specific requirements for the continuing airworthiness of aircraft. When the State of Design issues an AD against a type of aircraft registered in Australia, CASA must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian-registered aircraft meet international safety standards. In the case of AD/CESSNA 500/13, which affected Cessna 500 model aeroplanes, CASA assessed the AD and decided to cancel it because the unsafe condition it addressed no longer exists. This cancellation became effective on 25 September 2008, and no replacement AD was necessary.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include the requirement for CASA to assess ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs. Additionally, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in their country. The State of Design, meanwhile, must provide necessary information to maintain the airworthiness of aircraft types, aligning with the obligations under Annex 8 of the Convention on International Civil Aviation. These obligations are integral to maintaining international standards of aviation safety and ensuring the safety of air navigation.
In terms of consequences for breach, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences, penalties, or consequences for non-compliance with ADs. However, non-compliance with ADs can lead to significant risks, including potential civil or criminal liabilities if an unsafe condition results in an accident or incident. The regulations enforce the need for aircraft to meet certain safety standards, and failure to adhere to these standards can result in severe penalties, including fines, imprisonment, or both, under other aviation-related legislation. The primary focus is on ensuring the safety of air navigation and the airworthiness of aircraft, rather than detailing specific penalties within the ADs themselves.
