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 500/5 Amendment 1 affecting Cessna 500 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 500/5 Amendment 1. 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 Manager, Airframe and Structures, 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 by the Parliament of Australia to establish a framework for ensuring the safety and efficiency of civil aviation. This Act addresses the need for comprehensive regulation of aviation activities within Australia, aiming to safeguard public safety and to promote the orderly development of civil aviation. One of the mechanisms through which the Act achieves these objectives is through the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA), as detailed in the Civil Aviation Safety Regulations 1998. This regulatory approach is designed to ensure that all aircraft and aeronautical products meet the necessary safety standards. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue airworthiness directives, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. The Civil Aviation Act 1988 thus plays a critical role in harmonising Australia’s aviation safety practices with international standards, particularly those set by the International Civil Aviation Organization (ICAO).
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) that are critical for maintaining the safety of aircraft and aeronautical products. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products to ensure compliance with safety standards. Such ADs apply to aircraft registered in Australia and are subject to the continuing airworthiness responsibilities of both the State of Design and the State of Registry, in accordance with the Convention on International Civil Aviation. This regulatory mechanism ensures that any unsafe conditions identified with specific aircraft types are addressed promptly and effectively. The ADs are legislative instruments, subject to disallowance under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, which also means they are subject to scrutiny and potential cancellation if the unsafe conditions they address are no longer present. The specific AD/CESSNA 500/5 Amendment 1, issued for Cessna 500 model aeroplanes, was cancelled by CASA because the unsafe condition it was addressing no longer existed, demonstrating the dynamic nature of this regulatory tool in response to evolving safety needs. The cancellation of such directives is based on Australia's obligations under international conventions and does not require public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 allows the Governor-General to create regulations for the Act, specifically under section 98, with a focus on air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments under the Acts Interpretation Act 1901. Furthermore, Annex 8 to the Convention on International Civil Aviation places the responsibility of ensuring an aircraft type's continuing airworthiness on the State of Design, which must provide necessary information to States of Registry. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft, and must develop or adopt appropriate requirements to fulfil this responsibility.
The obligations imposed by the Civil Aviation Safety Regulations 1998 and the Convention on International Civil Aviation on parties or entities they govern include ensuring the continuing airworthiness of aircraft and aeronautical products. The State of Design must provide information necessary to maintain an aircraft type's airworthiness, while the State of Registry is responsible for the airworthiness of individual aircraft. CASA, as the regulatory body, must issue ADs when necessary and ensure compliance with international obligations. CASA is also responsible for assessing and cancelling ADs when the unsafe condition they address no longer exists, as demonstrated in the case of AD/CESSNA 500/5 Amendment 1.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, penalties, or consequences for breach in relation to airworthiness directives. However, non-compliance with ADs can lead to various civil or criminal consequences under other sections of the Act, such as the imposition of fines or imprisonment. The severity of these consequences would depend on the specific nature of the non-compliance and the discretion of the court. Additionally, the failure to adhere to international obligations under the Convention on International Civil Aviation could result in diplomatic or regulatory repercussions from other Contracting States.
