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 207/11 affecting Cessna 207 model aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 207/11. The cancellation will become effective on 23 October 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, 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 framework for the regulation of civil aviation in Australia, with a focus on safety and efficiency. This legislation empowers the Governor-General to issue regulations aimed at ensuring the safety of air navigation. Complementing this Act are the Civil Aviation Safety Regulations 1998, which provide a detailed regulatory structure for aviation safety, including the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are legislative instruments that mandate corrective actions for aircraft or aeronautical products to maintain their airworthiness. The Civil Aviation Act and associated regulations aim to align Australian practices with international standards, as outlined in the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, plays a critical role in ensuring compliance with these standards by issuing and managing ADs. The Act and regulations thus collectively address the need for robust and internationally compliant aviation safety measures.
Scope and Application
The Civil Aviation Act 1988 and the associated Civil Aviation Safety Regulations 1998 provide the legislative framework through which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) aimed at ensuring the safety of aircraft and aeronautical products within Australia. These regulations apply to all aircraft registered in Australia and extend to any aeronautical products used on those aircraft. The ADs are designed to address specific safety concerns related to aircraft types or specific components, and they are issued in compliance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, is mandated to assess ADs issued by the State of Design and to issue corresponding Australian ADs if necessary. In the specific case of AD/CESSNA 207/11 affecting Cessna 207 model aeroplanes, CASA has determined that the unsafe condition no longer exists, leading to the cancellation of this directive. This process does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. The ADs are considered disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003, thereby highlighting their regulatory nature and importance in maintaining aviation safety standards.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 set forth the requirements and processes for issuing airworthiness directives (ADs). Specifically, section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. This process is governed under the authority of the State of Design, which has overall responsibility for the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. CASA, acting as Australia's national airworthiness authority, is required to assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the safety requirements.
The obligations and requirements imposed by the Act and Regulations on parties and entities primarily revolve around the maintenance of airworthiness standards. CASA must diligently assess the information provided by the State of Design concerning any ADs and determine if they need to be issued in Australia. The State of Registry is also responsible for ensuring the continuing airworthiness of individual aircraft, necessitating the development or adoption of requirements to meet these standards. These obligations ensure that all stakeholders are aware of their responsibilities and the steps they must take to maintain the safety and airworthiness of aircraft in accordance with international standards.
In terms of offences, penalties, or consequences for breach, the Act does not explicitly outline specific offences or penalties related to the issuance or non-compliance with ADs. However, non-compliance with ADs could potentially lead to safety issues and may result in enforcement actions by CASA. The severity of these actions could range from fines to grounding of the aircraft until the required actions are taken. The maximum penalties for such breaches are not specified in the provided text but would typically be determined based on the nature and severity of the non-compliance and the associated safety risks. CASA has the authority to enforce compliance through various regulatory measures to ensure that airworthiness standards are upheld.
