CIVIL AVIATION ACT 1988
CIVIL AVIATION 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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 United States FAA has issued AD 2004-24-07 affecting Boeing 737-600, -700, -800 and -900 series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/236 which will become effective on 17 February 2005.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, addresses the need for stringent regulations to ensure the safety of air navigation and the continuing airworthiness of aircraft. This legislation empowers the Governor-General to make regulations under section 98, thereby facilitating the creation of safety standards and directives by the Civil Aviation Safety Authority (CASA). The Civil Aviation Regulations 1998 further support these objectives by allowing CASA to issue airworthiness directives for specific aircraft or aeronautical products under regulation 39.001. The issuance of such directives is in line with international obligations under Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design provides necessary information to ensure the continuing airworthiness of aircraft types. The Civil Aviation Act 1988 thus seeks to harmonise domestic aviation safety standards with international practices, ensuring that Australia meets its commitments under global aviation agreements while safeguarding the public from aviation-related hazards.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia, ensuring that the safety of air navigation is maintained and international obligations under the Convention on International Civil Aviation are fulfilled. Under section 98 of the Act, the Governor-General can make regulations that serve the Act’s objectives, with regulation 39.001 specifically empowering the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products. These ADs are legal instruments that can be disallowed under section 46A of the Acts Interpretation Act 1901. The Act applies to CASA, as the national airworthiness authority, and to aircraft registered in Australia, requiring CASA to assess and, if necessary, issue Australian ADs in response to ADs from the State of Design. The geographic reach of the Act is national, with CASA acting on behalf of Australia in compliance with international conventions. ADs are issued without public consultation because they are based on international obligations and assessments of information from the State of Design, as mandated by Annex 8 to the Convention on International Civil Aviation. This process ensures that aircraft maintain their airworthiness in accordance with international standards.
Key Provisions
The Civil Aviation Act 1988, complemented by the Civil Aviation Regulations 1998, sets forth the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for certain types of aircraft or aeronautical products. These ADs serve as enforceable directives aimed at ensuring the continuing airworthiness of aircraft and aeronautical products. Such directives are typically issued in response to findings by the State of Design, which holds the primary responsibility for ensuring the airworthiness of an aircraft type under Annex 8 of the Convention on International Civil Aviation.
The obligations imposed by the Act and the Regulations on CASA and other entities are significant. CASA must assess any ADs issued by the State of Design, and if deemed necessary, issue corresponding Australian ADs to enforce the same requirements domestically. This process ensures that Australian-registered aircraft meet international safety standards. Furthermore, the State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. This includes implementing ADs issued by CASA or by other States of Design where applicable.
Breaching the requirements of an AD can lead to severe consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can result in significant penalties. Civil penalties can include substantial fines, and in more severe cases, criminal penalties can be imposed. The exact financial penalties are not specified in the Act but are generally severe enough to ensure compliance with airworthiness standards. Additionally, CASA has the authority to take enforcement actions against non-compliant aircraft, which could include grounding the aircraft until the required compliance is achieved. Such enforcement actions are critical to maintaining the high safety standards mandated by the Act.
