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/AC/32 affecting Twin Aero Commander 680FL model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/AC/32. The cancellation will become effective on 31 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 is the primary piece of legislation governing civil aviation in Australia. It was enacted to establish a legal framework that ensures the safety and efficiency of civil aviation in the country. The Act provides the authority for the creation and enforcement of regulations necessary to maintain airworthiness and safety standards, aligning with international conventions and agreements. One significant aspect of the Act is its provision for the issuance of airworthiness directives, as detailed in the Civil Aviation Safety Regulations 1998. These directives are crucial for maintaining the continuing airworthiness of aircraft, ensuring they meet necessary safety standards. The Act empowers the Civil Aviation Safety Authority (CASA) to issue these directives, thereby facilitating compliance with both national and international aviation safety requirements. This legislative framework is essential for the effective oversight and regulation of civil aviation activities in Australia.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Regulation 39.001 of these regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, which are considered disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. This regulatory power is exercised in alignment with the State of Design’s responsibility under Annex 8 to the Convention on International Civil Aviation for ensuring the continuing airworthiness of aircraft types. CASA, as Australia’s national airworthiness authority, is tasked with assessing ADs issued by the State of Design and, where necessary, issuing corresponding Australian ADs. This regulatory approach ensures that all aircraft registered in Australia meet the required safety standards. The issuance, assessment, and cancellation of ADs by CASA, such as the recent cancellation of AD/AC/32 for Twin Aero Commander 680FL model aircraft, is conducted without public consultation as mandated by international obligations and determined by the Office of Best Practice Regulation to not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance and management of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to create regulations to ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901 and regulation under the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations require CASA to issue ADs when necessary to maintain the continuing airworthiness of aircraft. This includes assessing information from the State of Design and, if appropriate, issuing corresponding ADs to mandate those requirements for aircraft on the Australian Register. The State of Design has a responsibility under Annex 8 of the Convention on International Civil Aviation to provide information necessary for the continuing airworthiness of an aircraft type. When a State of Design issues an AD, CASA must review this information and act accordingly. In the case of the Twin Aero Commander 680FL model aircraft, CASA assessed the AD/AC/32 and determined that it should be cancelled due to the resolution of the unsafe condition. This cancellation was in accordance with Australia's obligations under the Convention on International Civil Aviation, and no consultation with the Australian public or a Regulatory Impact Statement was required.
The Act and Regulations also outline the consequences for non-compliance with ADs. Operators and owners of aircraft must adhere to the requirements specified in the ADs to ensure compliance with safety standards. Failure to comply with an AD can result in various civil and criminal penalties. Civil penalties may include fines, and in severe cases, CASA may revoke or suspend the aircraft's certificate of airworthiness, preventing it from flying. Criminal penalties may apply for gross negligence or willful disregard of ADs, resulting in substantial fines or imprisonment. The maximum penalties vary depending on the severity of the breach and the specific regulations involved, but they are designed to enforce compliance and maintain the highest safety standards in aviation.
