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 210/27 affecting Cessna 210 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 210/27. The cancellation will become effective on 10 April 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 Acting Manager, Systems and New Technologies 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 regulate civil aviation in Australia and to ensure the safety of air navigation, among other things. Pursuant to this Act, the Civil Aviation Safety Regulations 1998 were created to provide further detail on how safety standards are to be upheld within the industry. One mechanism established under these regulations is the ability for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs), which are legislative instruments that mandate specific actions to address safety issues with aircraft or aeronautical products. The Act allows for the Governor-General to make regulations in the interests of safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for certain kinds of aircraft or aeronautical products. The ADs serve as a means for states to communicate necessary information to ensure the continuing airworthiness of aircraft, in line with the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, apply to all entities and persons involved in civil aviation in Australia, including aircraft operators, manufacturers, and maintenance organisations. These regulations are designed to ensure the safety of air navigation and the continuing airworthiness of aircraft registered in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that must comply with the requirements of the Legislative Instruments Act 2003. The ADs issued by CASA are informed by international standards and practices, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of an aircraft type with the State of Design and the State of Registry. The jurisdictional reach of these regulations is national, applying to all aircraft registered in Australia regardless of their operation within state borders. There are no stated exclusions or thresholds specified in the regulations, but they do allow for the cancellation of ADs when the unsafe conditions they address are no longer present, as demonstrated in the case of AD/CESSNA 210/27, which was cancelled by CASA on 10 April 2008 due to the resolution of the safety issue.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. These directives are critical tools for ensuring the continued airworthiness of aircraft and are considered legislative instruments as per section 46A of the Acts Interpretation Act 1901 and section 6 of the Legislative Instruments Act 2003.
The obligations under this Act and the associated regulations are primarily concerned with the safety and airworthiness of aircraft. The State of Design, which is responsible for the overall airworthiness of an aircraft type, must provide necessary information to ensure the continuing airworthiness of the aircraft type. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft. CASA, as Australia’s national airworthiness authority, is tasked with assessing information from the State of Design and, if appropriate, issuing an Australian AD to mandate the requirements of the State of Design.
In terms of consequences, the Act and regulations do not explicitly detail specific offences, penalties, or consequences for breaches of ADs. However, the issuance of ADs and their subsequent implementation are critical for ensuring compliance with international standards under the Convention on International Civil Aviation, specifically Annex 8. Non-compliance with ADs could potentially lead to severe safety issues and may result in enforcement actions by CASA, which could include grounding of aircraft, fines, or other regulatory sanctions. The detailed provisions and enforcement mechanisms are typically found in other sections of the Civil Aviation Act 1988 and related regulations.
