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 337/20 affecting Cessna T337G aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 337/20. The cancellation will become effective on 13 March 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, with a particular focus on ensuring the safety of air navigation. Under this Act, the Governor-General has the authority to create regulations that serve the interests of safety in air navigation. In line with this mandate, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as crucial instruments in maintaining the continuing airworthiness of aircraft and are subject to the disallowance provisions under the Acts Interpretation Act 1901. CASA's responsibility is to assess and, if necessary, issue Australian ADs in response to directives from the State of Design, in adherence to the Convention on International Civil Aviation. This legislative framework ensures that Australia meets its international obligations while safeguarding the safety of its airspace.
Scope and Application
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Safety Regulations 1998, encompasses a comprehensive regulatory framework designed to ensure the safety and airworthiness of aircraft within Australian airspace. This Act applies to all aircraft registered in Australia, as well as to the Civil Aviation Safety Authority (CASA), which serves as the national airworthiness authority responsible for implementing and enforcing aviation safety regulations. The scope of the Act extends to both the State of Design and the State of Registry, with the latter being mandated to develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. The Act empowers CASA to issue airworthiness directives (ADs), which are legislative instruments under the Acts Interpretation Act 1901, to address safety concerns regarding specific types of aircraft or aeronautical products. These ADs are informed by international standards set forth in Annex 8 to the Convention on International Civil Aviation, obligating States of Design to provide necessary information to States of Registry to maintain airworthiness. In practice, CASA evaluates these directives and may issue corresponding Australian ADs or cancel them if the unsafe conditions they address no longer exist. The legislative process for ADs does not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and the international obligations underpinning their issuance.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework within which airworthiness directives (ADs) are issued and managed in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General is empowered to create regulations necessary for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the authority to issue ADs for specific types of aircraft or aeronautical products. These ADs, as stated in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and thus are legislative instruments as per section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to closely monitor airworthiness directives issued by the State of Design of an aircraft type and to assess whether these directives necessitate the issuance of corresponding ADs in Australia. The State of Design has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type, and must provide necessary information to the State of Registry to support this goal. Meanwhile, the State of Registry, which in Australia is CASA, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. When an AD is issued by a State of Design for a type of aircraft registered in Australia, CASA must evaluate the information and, if necessary, issue an Australian AD to implement the requirements specified by the State of Design.
Failure to comply with an AD can lead to significant consequences. The Civil Aviation Act 1988 and associated regulations establish clear penalties for non-compliance. Specifically, operating an aircraft that does not meet the airworthiness standards set out in an applicable AD can result in both civil and criminal penalties. Civil penalties can include fines up to a specified maximum amount, while criminal penalties can include imprisonment, reflecting the serious nature of non-compliance with these safety directives. It is crucial for operators and owners of affected aircraft to adhere to the requirements outlined in any AD to avoid these potential repercussions.
