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 400/82 affecting Cessna 441 model aircraft. CASA has assessed this AD and as a result has cancelled it. 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, Airframes, 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 comprehensive framework for the regulation of civil aviation in Australia, with a strong focus on ensuring the safety of air navigation. One of the mechanisms introduced by the Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments that mandate specific requirements for the continuing airworthiness of aircraft types and aeronautical products. The Civil Aviation Act 1988 empowers the Governor-General to make such regulations to maintain safety standards, thereby aligning with international obligations under the Convention on International Civil Aviation, particularly Annex 8, which assigns the State of Design with the responsibility for the continuing airworthiness of aircraft types. CASA, as Australia's national airworthiness authority, is mandated to assess and, if necessary, issue ADs that reflect the requirements of the State of Design for aircraft on the Australian Register. This ensures that Australian aircraft meet both national and international safety standards, thereby safeguarding the interests of the public and promoting safe air navigation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance of airworthiness directives (ADs) in Australia, aimed at ensuring the safety of air navigation. The Act applies to entities such as the Civil Aviation Safety Authority (CASA), which is responsible for the implementation and enforcement of these regulations. The ADs apply to all aircraft and aeronautical products registered in Australia, ensuring that their continuing airworthiness is maintained according to the standards set by the State of Design and the State of Registry. Geographically, this legislation applies across the Commonwealth of Australia, with CASA acting as the national airworthiness authority. The Act does not specify exclusions or exemptions but adheres to international obligations under the Convention on International Civil Aviation, specifically Annex 8, which mandates the continuing airworthiness responsibilities of States of Design and Registry. Subordinate instruments, such as ADs, extend the application of the Act by providing detailed safety requirements and mandates that must be followed by aircraft operators and manufacturers within Australia.
Key Provisions
The Civil Aviation Act 1988 provides the legal framework within which the Civil Aviation Safety Regulations 1998 operate, ensuring the safety of air navigation. Section 98 of the Act allows the Governor-General to create regulations that serve the interests of aviation safety, and 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. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003, and they are designed to ensure the continuing airworthiness of aircraft as required by Annex 8 to the Convention on International Civil Aviation.
The obligations under these regulations include the State of Design taking overall responsibility for the continuing airworthiness of an aircraft type and providing necessary information to the State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. When an AD is issued by a State of Design, CASA must evaluate this information and, if necessary, issue an Australian AD to enforce the State of Design's requirements. This process ensures that Australian-registered aircraft meet the safety standards mandated by international agreements.
Under the Civil Aviation Safety Regulations 1998, CASA has the authority to cancel an AD if the unsafe condition it addresses no longer exists. In this instance, AD/CESSNA 400/82, which affected Cessna 441 model aircraft, has been cancelled by CASA because the unsafe condition it was intended to address has been resolved. This cancellation will take effect on 25 September 2008, and no replacement AD is required. Given that the cancellation stems from Australia's obligations under the Convention on International Civil Aviation, no consultation with the Australian public has been necessary. Furthermore, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
Any breach of the provisions under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can lead to both civil and criminal consequences. Civil penalties may include fines, and in severe cases, criminal penalties could result in imprisonment. The exact penalties depend on the nature and severity of the breach, but they are intended to enforce compliance with aviation safety standards. CASA’s actions, such as issuing or cancelling an AD, are taken in accordance with the legislative authority granted by the Act, ensuring that all measures are legally sound and justifiable under the relevant provisions.
