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/BELL 206/81 affecting Bell 206L and 206L-1 series Helicopters. CASA has assessed this AD and as a result has cancelled Australian AD/BELL 206/81. The cancellation will become effective on 30 July 2009. 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, enacted by the Commonwealth Parliament, aims to ensure the safety and efficiency of civil aviation in Australia. In line with this objective, the Act empowers the Governor-General to make regulations for the safety of air navigation, with the Civil Aviation Safety Regulations 1998 providing the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). An AD, as a legislative instrument under the Legislative Instruments Act 2003, mandates requirements to ensure the continuing airworthiness of aircraft types, in accordance with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 mandate that CASA must issue Australian ADs when necessary to comply with ICAO standards and the obligations of the State of Design. The Act also stipulates that ADs do not require a Regulatory Impact Statement and generally do not necessitate public consultation, as they are based on international obligations and safety assessments.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under these laws, the Civil Aviation Safety Authority (CASA) is empowered to issue ADs for specific types of aircraft or aeronautical products to ensure compliance with safety standards. These regulations apply to all entities involved in the aviation industry within Australia, including aircraft manufacturers, operators, and maintenance providers. The geographic reach of these regulations is national, as CASA acts on behalf of the Australian government to enforce airworthiness standards. The ADs serve as legislative instruments, subject to disallowance and review under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. Although ADs are typically issued under international agreements such as Annex 8 to the Convention on International Civil Aviation, CASA retains the discretion to tailor these directives to meet Australian requirements, ensuring the continuing airworthiness of aircraft registered within the country. The issuance, amendment, or cancellation of ADs by CASA is conducted without mandatory public consultation, and these actions do not require a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 establish the framework for issuing airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations for air navigation safety. Regulation 39.001 of the Regulations permits the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products (39.001). Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, and as legislative instruments under section 6 of the Legislative Instruments Act 2003.
The obligations imposed by these provisions are primarily centred around the roles of the State of Design and the State of Registry. The State of Design is responsible for ensuring the continuing airworthiness of an aircraft type and must provide necessary information to the State of Registry (Annex 8, Convention on International Civil Aviation). The State of Registry, in this case CASA, must assess the information from the State of Design and, if necessary, issue an Australian AD to enforce the requirements. When CASA issued AD/BELL 206/81 for Bell 206L and 206L-1 series Helicopters, it had to evaluate the AD and determine its applicability in Australia, ultimately leading to its cancellation.
Failure to comply with ADs can lead to significant consequences. Although specific offences and penalties are not detailed in the provided text, non-compliance with airworthiness directives can generally result in serious safety risks, leading to potential enforcement actions by CASA. Such actions could include fines, grounding of aircraft, or other regulatory sanctions. The severity of these penalties depends on the nature and extent of the non-compliance and the potential risk posed to public safety.
The cancellation of AD/BELL 206/81 exemplifies the procedural approach taken by CASA. As the AD was cancelled due to Australia’s international obligations, there was no requirement for public consultation. Additionally, the Office of Best Practice Regulation has concluded that ADs do not necessitate a Regulatory Impact Statement, streamlining the regulatory process while maintaining safety standards. The Manager Airframe and Structures, within the Airworthiness Engineering Group, made the AD on behalf of CASA, adhering to the statutory requirements outlined in subsection 84A(2) of the Act.
