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/PHS/13 affecting Hamilton Standard 14SF-5 and 14SF-7 propellers. CASA has assessed this AD and as a result has cancelled Australian AD/PHS/13. 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 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, focusing on ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to make regulations that promote safety, and the Civil Aviation Safety Regulations 1998 further detail the mechanisms for maintaining airworthiness, including the issuance of airworthiness directives (ADs). These ADs are legislative instruments that mandate the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Authority (CASA) acts as Australia’s national airworthiness authority, responsible for issuing and managing ADs to ensure compliance with both national and international safety requirements. In the case of AD/PHS/13, CASA cancelled the directive pertaining to Hamilton Standard 14SF-5 and 14SF-7 propellers, as the unsafe condition no longer exists, reflecting Australia’s commitment to international obligations and the maintenance of aviation safety standards.
Scope and Application
The Civil Aviation Act 1988, as amended, provides the legislative framework for the regulation of civil aviation in Australia, encompassing safety, air navigation, and operational standards. Under this Act, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs serve as a key mechanism for ensuring the continuing airworthiness of aircraft within Australia. ADs are mandated by regulation 39.001 of the Civil Aviation Safety Regulations 1998, and their issuance is subject to the provisions of the Acts Interpretation Act 1901, making them disallowable instruments. The ADs are typically issued in response to safety concerns identified by the State of Design or other ICAO Contracting States, ensuring compliance with international standards and obligations under the Convention on International Civil Aviation. The State of Registry, in this case CASA, is responsible for evaluating and implementing these directives as necessary to maintain the safety of aircraft registered in Australia. The ADs are legislative instruments issued under the authority of the Act and do not require public consultation or a Regulatory Impact Statement as per the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, establishes a framework for the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001, respectively. This legislation empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, ensuring the safety of air navigation. Section 39.001(5) clarifies that ADs are disallowable instruments, which means they are subject to parliamentary scrutiny, and as legislative instruments, they fall under the purview of the Legislative Instruments Act 2003.
The obligations imposed by these regulations on parties include adherence to ADs issued by CASA, ensuring that aircraft remain airworthy. The State of Design, as defined under Annex 8 to the Convention on International Civil Aviation, bears the responsibility for providing necessary information to maintain the continuing airworthiness of an aircraft type. Similarly, the State of Registry, in this case, CASA, must ensure that Australian aircraft meet continuing airworthiness standards. This entails assessing foreign ADs, such as those issued by the State of Design, and, if necessary, issuing corresponding Australian ADs to mandate the required safety measures.
Failure to comply with ADs can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to both civil and criminal penalties. Civil penalties can include fines, while criminal penalties may include imprisonment, reflecting the serious nature of ensuring aviation safety. The exact penalties depend on the specific breach and the discretion of the court, but they serve as a deterrent against non-compliance, ensuring that all stakeholders prioritise the safety of air navigation.
In the specific instance of AD/PHS/13 affecting Hamilton Standard 14SF-5 and 14SF-7 propellers, CASA assessed the AD and determined that the unsafe condition no longer existed. Consequently, Australian AD/PHS/13 was cancelled effective 9 April 2009. This action was in line with Australia’s obligations under the Convention on International Civil Aviation, which did not necessitate public consultation or a Regulatory Impact Statement. The cancellation was 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, ensuring the process adhered to legislative requirements.
