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/CESSNA 185/26 affecting Cessna 185 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 3 July 2008. 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, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a comprehensive framework for the regulation of civil aviation in Australia, with a strong emphasis on safety and efficiency. The Act empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation, which includes the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are critical for maintaining the continuing airworthiness of aircraft types and individual aircraft, aligning with international standards set forth by the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further detail the process by which CASA can issue these directives, which are considered legislative instruments. In a recent development, CASA cancelled AD/CESSNA 185/26 affecting Cessna 185 aircraft, reflecting Australia's commitment to international obligations and ensuring that the safety and airworthiness requirements remain consistent with global standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide a framework for the issuance of airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) holding the authority to issue these directives for specific kinds of aircraft or aeronautical products as per regulation 39.001. This legislation applies to all aircraft registered in Australia, their operators, and relevant aviation industry stakeholders. The geographic reach of this legislation is national, applying uniformly across all states and territories in Australia. Furthermore, as ADs are considered legislative instruments under the Legislative Instruments Act 2003, they hold legal weight and must comply with the disallowance provisions of the Acts Interpretation Act 1901. The State of Registry, in this case CASA, is responsible for ensuring the continuing airworthiness of aircraft registered in Australia, a duty that includes assessing and, if necessary, issuing Australian ADs based on directives from the State of Design. The cancellation of AD/CESSNA 185/26 for Cessna 185 aircraft, effective from 3 July 2008, exemplifies the application of this regulatory framework and highlights the importance of international obligations under the Convention on International Civil Aviation in shaping domestic airworthiness directives.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, in line with section 6 of the Legislative Instruments Act 2003, they are deemed legislative instruments. This regulatory framework ensures that safety measures are consistently applied and monitored across the aviation industry.
Compliance with the ADs is mandatory for aircraft registered in Australia. The State of Design, responsible for the overall airworthiness of an aircraft type, must provide necessary information to the States of Registry to maintain airworthiness. Consequently, the State of Registry, which in this case is CASA, must assess the information provided by the State of Design and, if deemed necessary, issue an Australian AD to enforce the required safety measures. This collaborative approach ensures that all stakeholders adhere to international standards, thereby maintaining high safety levels within the Australian aviation sector.
Failure to comply with the ADs can result in significant consequences. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline various penalties and legal ramifications for non-compliance. For instance, operating an aircraft that does not meet the mandated airworthiness standards can lead to fines or imprisonment. The specific penalties may vary depending on the severity of the breach, but they are designed to enforce strict adherence to safety regulations. This stringent enforcement underscores the importance of maintaining high safety standards in the aviation industry.
The process for issuing and cancelling ADs is well-defined and transparent. For example, AD/CESSNA 185/26, which affected Cessna 185 aircraft, was reviewed by CASA and subsequently cancelled on 3 July 2008. This cancellation was due to Australia's obligations under the Convention on International Civil Aviation, and no replacement AD was required. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, indicating a streamlined approach to managing airworthiness directives. The cancellation was executed by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act, ensuring that all actions are taken in compliance with the legal framework.
