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/RAD/17 affecting Skyphone VC-10 series VHF Transceivers. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/17. The cancellation will become effective on 9 April 2009. 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 Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Parliament of Australia, serves as the primary legislative framework governing civil aviation in Australia. This Act aims to ensure the safety and efficiency of civil aviation and establishes the Civil Aviation Safety Authority (CASA) as the national airworthiness authority. The Act empowers CASA to issue airworthiness directives to maintain the continuing airworthiness of aircraft. This legislative intervention was necessary to address the need for stringent safety regulations in the rapidly evolving field of civil aviation. In line with international obligations under the Convention on International Civil Aviation, CASA has the authority to issue and cancel airworthiness directives, ensuring that Australian aviation standards align with global safety protocols. The Civil Aviation Safety Regulations 1998 further detail the mechanisms by which CASA implements these directives, reflecting a commitment to harmonising domestic regulations with international standards to safeguard public safety and maintain the integrity of the aviation industry.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the purposes of the Act and the safety of air navigation, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The ADs are intended to ensure the continuing airworthiness of aircraft, aligning with the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation, where the State of Design has overall responsibility for the airworthiness of an aircraft type, and the State of Registry must ensure the continuing airworthiness of aircraft registered within its territory. CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue Australian ADs to mandate the requirements of the State of Design. In cases where ADs are cancelled, such as the AD/RAD/17 for Skyphone VC-10 series VHF Transceivers, it is due to the obligations under the Convention on International Civil Aviation, and no public consultation or Regulatory Impact Statement is required as determined by the Office of Best Practice Regulation.
Key Provisions
The main sections relevant to the issuing and management of airworthiness directives (ADs) under the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 are sections 98 and 39.001. Section 98 of the Act empowers the Governor-General to make regulations in the interests of air navigation safety, and regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and legislative instruments under section 6 of the Legislative Instruments Act 2003.
Under these provisions, CASA, as Australia’s national airworthiness authority, is tasked with assessing ADs issued by the State of Design and determining whether to issue corresponding Australian ADs. This process is crucial for ensuring the continuing airworthiness of aircraft registered in Australia. In line with Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the ongoing airworthiness of aircraft types, while the State of Registry is responsible for the airworthiness of individual aircraft. When a State of Design issues an AD, CASA must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design.
The obligations under these regulations include the requirement for CASA to assess and potentially issue Australian ADs when necessary, ensuring that all aircraft registered in Australia meet the continuing airworthiness standards. This involves thorough evaluation of ADs issued by other states to ensure they align with Australian safety standards. The process also includes cancelling ADs when unsafe conditions no longer exist, as seen with the cancellation of Australian AD/RAD/17 affecting Skyphone VC-10 series VHF Transceivers, effective from 9 April 2009.
The Civil Aviation Safety Regulations 1998 also outline the legal consequences of breaching ADs. While the specific offences, penalties, or civil/criminal consequences are not detailed in the provided text, it is understood that non-compliance with ADs can lead to serious legal repercussions. Such breaches can result in enforcement actions by CASA, including fines, suspension or revocation of airworthiness certificates, and other regulatory penalties. The exact penalties would depend on the severity of the breach and applicable aviation laws.
