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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/TPE 331/60 affecting Honeywell TPE 331 engines in 2003. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 24 September 2009. No replacement AD is required.
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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, 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 legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the industry. The Act empowers the Governor-General to make regulations in the interest of air navigation safety, and under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. This legislative mechanism enables CASA to mandate specific actions to maintain the airworthiness of aircraft, thus fulfilling international obligations under the Convention on International Civil Aviation, particularly those pertaining to continuing airworthiness. ADs are crucial for maintaining safety standards, and their issuance aligns with the overarching policy objective of safeguarding public safety within civil aviation. The cancellation of an existing airworthiness directive, such as AD/TPE 331/60 for Honeywell TPE 331 engines, reflects CASA's commitment to adhering to international conventions and continuously updating regulatory standards to meet evolving safety requirements.
Scope and Application
The Civil Aviation Act 1988, as amended, provides the legislative framework for civil aviation in Australia and empowers the Governor-General to issue regulations necessary for the safety of air navigation. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs serve as legislative instruments and are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for the continuing airworthiness of an aircraft type and requires it to provide necessary information to the States of Registry. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft by developing or adopting relevant requirements. The ADs issued by CASA, such as the AD/TPE 331/60 affecting Honeywell TPE 331 engines, are instrumental in maintaining airworthiness standards and are issued under the authority of the Act. Given their nature and the international obligations under the Convention, these directives are not subject to public consultation or the requirement for a Regulatory Impact Statement. The cancellation of an AD, such as the one affecting the Honeywell TPE 331 engines, is made by CASA in compliance with the legislative requirements and reflects Australia's adherence to international aviation safety standards.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations that support the Act's objectives, specifically for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 extends this authority to the Civil Aviation Safety Authority (CASA), enabling it to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. This regulatory framework is intended to ensure that all aircraft meet specific safety standards, which are crucial for maintaining the integrity of air travel. Section 39.001(5) of the Civil Aviation Safety Regulations 1998 further clarifies that an AD is a disallowable instrument, thus making it a legislative instrument under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these regulations are primarily centred on ensuring the continuing airworthiness of aircraft. According to Annex 8 of the Convention on International Civil Aviation, the State of Design holds primary responsibility for the airworthiness of an aircraft type and must supply necessary information to States of Registry to maintain this airworthiness. Similarly, the State of Registry, which in Australia is CASA, must establish or adopt requirements to ensure that individual aircraft remain airworthy. These obligations require cooperation and information sharing between different states and authorities to uphold safety standards universally.
Failure to comply with the requirements set out in the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in serious consequences. While specific offences and penalties are not detailed in the provided text, it is clear that breaches of these regulations can lead to significant civil or criminal repercussions. The severity of these consequences would likely depend on the nature and impact of the non-compliance, potentially including fines or other penalties as stipulated by relevant laws. The legislative nature of ADs underscores the importance of adherence to these regulations, as non-compliance could endanger the safety of air navigation and potentially result in severe legal ramifications.
