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/BEECH 76/4 affecting Beechcraft 76 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 76/4. The cancellation will become effective on 3 July 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive legislative framework for civil aviation in Australia, addressing issues pertinent to the safety and regulation of air navigation. This Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, as stipulated in section 98. Complementing this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, as per regulation 39.001. These directives are essential for maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. The issuance and management of ADs are integral to fulfilling Australia's obligations under the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and the State of Registry.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the regulation and safety oversight of civil aviation in Australia. Specifically, the Act empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products, thereby establishing a legislative framework for maintaining the safety and airworthiness of aircraft operating in Australia. These airworthiness directives are considered legislative instruments and can be subject to disallowance under the Acts Interpretation Act 1901. The application of these directives extends to all aircraft registered in Australia, ensuring compliance with both national and international standards, including those set by the International Civil Aviation Organization (ICAO). CASA, as the national airworthiness authority, plays a critical role in assessing and implementing these directives to maintain the safety and airworthiness of aircraft within Australia's jurisdiction.
Key Provisions
The Civil Aviation (Safety) Regulations 1998 (regulation 39.001) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003 and are issued to ensure the continuing airworthiness of aircraft, in line with the requirements of the Convention on International Civil Aviation (Annex 8). ADs are critical for maintaining safety standards and are issued by most ICAO Contracting States, including Australia. The State of Design, which is responsible for the overall continuing airworthiness of an aircraft type, must provide necessary information to the State of Registry, which then ensures the airworthiness of individual aircraft on its register.
The obligations imposed on parties governed by this Act include ensuring that the State of Design provides all necessary information to the State of Registry to maintain airworthiness. CASA, as Australia’s national airworthiness authority, must assess this information and issue Australian ADs if necessary. These ADs mandate the requirements for ensuring the continuing airworthiness of aircraft on the Australian Register. In the case of AD/BEECH 76/4, which affected Beechcraft 76 model aircraft, CASA has cancelled this AD due to the unsafe condition no longer existing. The cancellation of AD/BEECH 76/4 will take effect on 3 July 2008, and no replacement AD is required.
Failure to comply with the ADs issued by CASA can result in civil and criminal penalties. Under section 84A of the Civil Aviation Act 1988, a person who contravenes an airworthiness directive may be liable for penalties. The maximum penalties for such contraventions are detailed in the regulations and can include fines or imprisonment, depending on the severity of the breach. These provisions underscore the importance of adhering to ADs to maintain the safety of air navigation and ensure the airworthiness of aircraft operating within Australia.
