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 210/18 affecting Cessna 210 aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/CESSNA 210/18. The cancellation will become effective on 10 April 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 Acting 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 provide a comprehensive framework for regulating civil aviation in Australia, with a strong emphasis on safety and efficiency. This Act serves to establish and empower the Civil Aviation Safety Authority (CASA) to oversee and enforce aviation safety standards. One of the key gaps it was designed to address is ensuring the safety and airworthiness of aircraft operating within Australian airspace. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further detail the requirements and processes for maintaining airworthiness, including the issuance of airworthiness directives (ADs). The enactment of this legislation was overseen by the Australian Parliament, with the overarching policy objective being to enhance and maintain the highest possible safety standards in civil aviation.
Scope and Application
The Civil Aviation Act 1988, as amended, and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the regulation of airworthiness directives (ADs) in Australia. Under this Act, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs concerning types of aircraft or aeronautical products to ensure the safety of air navigation. These ADs are legislative instruments and can be subject to disallowance under the Acts Interpretation Act 1901. The scope of these regulations extends to any aircraft registered within Australia, as well as any aeronautical products used in Australian airspace, thereby encompassing a wide range of entities including aircraft manufacturers, operators, and aviation maintenance professionals. The ADs are designed to mandate compliance with airworthiness standards in alignment with international obligations under the Convention on International Civil Aviation, particularly those concerning the continuing airworthiness of aircraft types. While ADs are critical regulatory tools, they do not require consultation with the public or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The authority to issue and cancel such directives is vested in CASA, which acts in accordance with its statutory powers under the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to create regulations that ensure the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. These ADs, as outlined in subregulation 39.001(5), are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are thus legislative instruments. According to Annex 8 of the Convention on International Civil Aviation, the State of Design is tasked with the overarching responsibility for the continuing airworthiness of an aircraft type and must supply all necessary information to the States of Registry to maintain this airworthiness. ADs serve as the primary means of disseminating such information and are issued by most International Civil Aviation Organization (ICAO) Contracting States.
The State of Registry, under Annex 8, is responsible for the continuing airworthiness of individual aircraft. This entails developing or adopting requisite requirements to ensure such airworthiness. When a State of Design issues an AD against an aircraft type registered in Australia, CASA, as the national airworthiness authority, must evaluate this information. If deemed necessary, CASA will issue an Australian AD to enforce the requirements of the State of Design. For instance, CASA issued and subsequently cancelled Australian AD/CESSNA 210/18 concerning Cessna 210 aircraft. This cancellation, effective from 10 April 2008, was due to the resolution of the unsafe condition and no replacement AD is required.
CASA's cancellation of AD/CESSNA 210/18 was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, hence no public consultation was conducted. Additionally, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement. The cancellation was authorised by the Acting Manager, Systems and New Technologies in the Airworthiness Engineering Branch, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on entities such as CASA include the assessment and enforcement of ADs issued by the State of Design, ensuring they align with the safety standards required under Australian law. Failure to comply with these obligations may result in safety risks to aircraft and passengers, potentially leading to severe civil or criminal consequences. The maximum penalties for breaches can vary but often include fines and imprisonment, depending on the severity and intent behind the violation. Such penalties serve to enforce adherence to the regulations and maintain the high safety standards mandated by the Civil Aviation Act 1988 and its subsidiary regulations.
