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.
The Civil Aviation Safety Authority or its predecessors issued AD/CESSNA 500/24 affecting Cessna 500 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 500/24. The cancellation will become effective on 25 September 2008. 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 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, enacted by the Australian Parliament, was established to ensure the safety and efficiency of civil aviation within Australia. This Act, along with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to address safety issues with aircraft or aeronautical products. ADs are crucial tools under the Convention on International Civil Aviation, with the State of Design having the overarching responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the individual aircraft's airworthiness. The policy objective of these regulations is to maintain and enhance the safety of air navigation in accordance with international standards. The Civil Aviation Safety Regulations 1998 specifically empower CASA to issue these directives, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. In this instance, AD/CESSNA 500/24, which affected Cessna 500 model aeroplanes, has been cancelled by CASA as the unsafe condition it was intended to address no longer exists, reflecting Australia's commitment to international aviation safety standards.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 apply to the issuance of airworthiness directives (ADs) that are critical for ensuring the safety of air navigation. Regulation 39.001 of these regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products, thereby establishing a framework for maintaining the continuing airworthiness of aircraft types and individual aircraft. This legislative framework is designed to align with international standards, particularly those set out in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for continuing airworthiness and mandates that States of Registry adopt necessary requirements to ensure safety. The ADs are legislative instruments that can be subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. In practice, CASA, as the regulatory authority, has the power to issue, modify, or cancel ADs based on safety assessments, as demonstrated by the cancellation of AD/CESSNA 500/24 for Cessna 500 model aeroplanes, which became effective from 25 September 2008. This cancellation was made without public consultation due to Australia’s international obligations and did not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, particularly section 98, provides the framework for the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Section 39.001(5) of the same regulations establishes that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and consequently, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. These directives are essential tools in maintaining the continuing airworthiness of aircraft as per Annex 8 to the Convention on International Civil Aviation, where the State of Design bears responsibility for providing necessary information to States of Registry to ensure ongoing safety.
The obligations imposed by the Civil Aviation Act 1988 and its associated regulations on the parties involved are significant. The State of Design, which is the country where the aircraft was originally designed, must ensure that all necessary information is provided to the State of Registry—the country where the aircraft is registered—to maintain its airworthiness. This includes the issuance of ADs when necessary. The State of Registry, in turn, must develop or adopt requirements to ensure that aircraft under its jurisdiction remain airworthy. CASA, as the regulatory body in Australia, is tasked with assessing and issuing ADs to fulfil these obligations. This process ensures that Australian-registered aircraft meet international safety standards.
Failure to comply with the provisions of the Civil Aviation Act 1988 and the associated regulations can lead to serious consequences. While specific offences and penalties are not detailed in the text, the overarching framework suggests that non-compliance with airworthiness directives or regulatory requirements could result in legal action. This may include civil or criminal penalties, although the exact penalties are not specified. The severity of these consequences would likely depend on the nature and extent of the non-compliance and its impact on aviation safety.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for maintaining the airworthiness of aircraft. They empower CASA to issue airworthiness directives, which are critical for ensuring that both States of Design and States of Registry meet their obligations under international conventions. Non-compliance with these regulations can lead to significant legal and safety repercussions, although the exact penalties are not detailed in the provided text.
