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.
State of Design ADs issued on or after 1 October 2009 are defined as ADs per Civil Aviation Safety Regulations Part 39.001A.
CASA issued AD/S-PUMA/53 Amdt 1 affecting Eurocopter AS 332 series helicopters. The EASA issued AD 2010-0014 on 26 January 2010 which supersedes the requirements of AD/S-PUMA/53 Amdt 1 and as such this AD has been cancelled. The EASA acts on behalf of France which is the state of design for these helicopters. The cancellation will become effective on 9 February 2010.
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, Continuing Airworthiness in the Airworthiness and Engineering Branch, on behalf of CASA, in accordance with subsection 94 (1) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety, efficiency, and orderly growth of civil aviation. One of the key objectives of the Act is to maintain and enhance the safety of air navigation and aircraft. The Civil Aviation Safety Regulations 1998 were introduced under this Act to provide detailed rules and standards for achieving these objectives. Specifically, regulation 39.001 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products to ensure their continuing airworthiness. As per subregulation 39.001(5), ADs are considered legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. This process ensures that CASA, as Australia’s national airworthiness authority, can mandate safety requirements when necessary, aligning with international standards set by the International Civil Aviation Organization (ICAO).
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance and management of airworthiness directives (ADs) in Australia. The Act and Regulations apply to all aircraft and aeronautical products within the Commonwealth, ensuring that safety standards are consistently maintained across the industry. Regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs, which are binding legislative instruments that mandate compliance with airworthiness requirements. These ADs apply to aircraft types registered in Australia and must align with the continuing airworthiness responsibilities of the State of Design and the State of Registry as outlined in Annex 8 of the Convention on International Civil Aviation. Notably, ADs issued by CASA are a means to enforce compliance with international safety standards domestically, ensuring that Australian-registered aircraft meet global benchmarks for airworthiness. Any AD issued by CASA is subject to disallowance and is considered a legislative instrument under the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, establishes the framework within which airworthiness directives (ADs) are issued. According to section 98 of the Act, the Governor-General has the authority to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 specifically grants the Civil Aviation Safety Authority (CASA) the power to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under subregulation 39.001(5) of the Civil Aviation Safety Regulations and section 46A of the Acts Interpretation Act 1901. This legislative framework ensures that ADs are issued in a manner that maintains the safety standards required under international conventions.
The obligations imposed by this legislation on CASA and other relevant entities are significant. CASA, as Australia's national airworthiness authority, is required to assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements of the State of Design. This ensures that all aircraft registered in Australia meet the necessary safety standards. Additionally, the State of Registry of an individual aircraft bears the responsibility for its continuing airworthiness. Under Annex 8 to the Convention on International Civil Aviation, the State of Design must provide all necessary information to ensure the continuing airworthiness of the aircraft type, and the State of Registry must implement measures to maintain this airworthiness.
Failure to comply with the requirements set out in the ADs can lead to significant consequences. While the Civil Aviation Safety Regulations 1998 do not specify explicit penalties for non-compliance with ADs, the overarching Civil Aviation Act 1988 provides for a range of enforcement actions. These may include fines and other penalties for non-compliance with ADs, which can be substantial. The Act also allows for criminal prosecution in cases of serious non-compliance, which could result in imprisonment. The specific penalties and enforcement mechanisms are detailed in other sections of the Civil Aviation Act and related regulations, ensuring that there are clear disincentives for failing to adhere to ADs.
