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/AUS/1 affecting Auster/Beagle A.61 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/AUS/1. The cancellation will become effective on 30 July 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, Airframe and Structures, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, with a strong emphasis on safety. The Act empowers the Governor-General to make regulations in the interests of air navigation safety, as demonstrated by the Civil Aviation Safety Regulations 1998. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products, ensuring that they meet safety standards. The ADs are legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901, and thus are subject to the scrutiny of the Legislative Instruments Act 2003. This framework ensures that Australia adheres to international standards, such as those outlined in Annex 8 to the Convention on International Civil Aviation, which places the responsibility of continuing airworthiness on the State of Design and the State of Registry. CASA, as Australia’s national airworthiness authority, assesses information from the State of Design and issues Australian ADs as necessary to comply with these international obligations. The process of issuing and cancelling ADs, such as AD/AUS/1 for Auster/Beagle A.61 series aeroplanes, is conducted in accordance with these regulations and does not require public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to section 98 of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory mechanism is crucial for ensuring the ongoing airworthiness of aircraft within Australia, aligning with international obligations under Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design responsibility for the continuing airworthiness of an aircraft type. CASA, as Australia's national airworthiness authority, is tasked with assessing and potentially issuing Australian ADs in response to directives from the State of Design. These ADs serve as legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are formulated to mandate compliance with specific safety standards. Notably, the issuance or cancellation of ADs does not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. This streamlined process allows CASA to respond efficiently to evolving safety concerns while maintaining compliance with international civil aviation standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 that pertain to the issuance of airworthiness directives (ADs) include section 98 of the Act, which allows the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Regulations, which permits the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These directives are legislative instruments and must comply with the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. The Civil Aviation Safety Authority, as Australia's national airworthiness authority, must assess and, if necessary, issue Australian ADs when a State of Design issues an AD affecting a type of aircraft on the Australian Register.
The obligations imposed on parties and entities by these provisions include ensuring that the State of Design provides necessary information for the continuing airworthiness of aircraft types, and that the State of Registry develops or adopts requirements to ensure the airworthiness of aircraft. CASA must assess information provided by the State of Design and, if appropriate, issue Australian ADs to mandate the requirements. The State of Registry must implement the ADs to maintain the airworthiness of individual aircraft on the Australian Register. These obligations are designed to ensure that aircraft remain safe and airworthy, consistent with international standards.
Breaches of the obligations set out in these regulations may result in civil or criminal consequences. While the specific provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not detail specific penalties for non-compliance with ADs, breaches of airworthiness regulations generally can lead to severe penalties. Civil penalties may include fines, and criminal penalties may include imprisonment, reflecting the seriousness of non-compliance with aviation safety regulations. The exact penalties would be determined by the court based on the nature and extent of the breach.
