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.
CASA issued AD/DH 104/30 affecting De Havilland DH 104 model aircraft in 1972. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 17 January 2008. No replacement AD is required, as the original unsafe condition is now addressed by AD/GENERAL/74 Amendment 1.
No consultation with the Australian public has taken place on this AD cancellation, because the cancellation results in a reduction of the regulatory burden. 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 Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was introduced to provide a comprehensive framework for the regulation of civil aviation in Australia, with a strong emphasis on safety and efficiency. The Act empowers the Governor-General to make regulations for the purposes of the Act, particularly with regard to the safety of air navigation, as seen in section 98. One significant regulatory tool under this Act is the issuance of airworthiness directives, which are detailed in the Civil Aviation Safety Regulations 1998. These regulations allow the Civil Aviation Safety Authority (CASA) to issue directives that mandate specific actions to ensure the continuing airworthiness of aircraft and aeronautical products. The policy objective of these directives is to maintain the highest safety standards in Australian civil aviation by addressing any unsafe conditions promptly.
The Civil Aviation Safety Regulations 1998 further clarify that an airworthiness directive is a disallowable instrument, subject to parliamentary scrutiny, and thus a legislative instrument under the Legislative Instruments Act 2003. The process of issuing and cancelling such directives is designed to align with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that Australia's regulatory practices are consistent with global norms. CASA's role as the national airworthiness authority involves assessing directives issued by the State of Design and, if necessary, issuing corresponding Australian directives to enforce safety requirements. The recent cancellation of AD/DH 104/30 affecting De Havilland DH 104 model aircraft exemplifies CASA’s commitment to maintaining up-to-date and relevant safety directives, reflecting a reduction in regulatory burden and improved safety measures.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of aircraft and aeronautical products in Australia. These ADs apply to specific kinds of aircraft or aeronautical products registered in Australia and aim to maintain their airworthiness in line with international standards, particularly those set by the International Civil Aviation Organization (ICAO). The scope of these regulations extends to mandating compliance with safety standards set by the State of Design for aircraft types registered in Australia. As Australia's national airworthiness authority, CASA must assess and implement these directives to ensure that aircraft within its jurisdiction maintain the required safety standards. The authority to issue and enforce these directives is supported by the Legislative Instruments Act 2003, which classifies ADs as disallowable instruments, thereby formalising their regulatory impact. This legislative framework ensures that all stakeholders, including aircraft operators and manufacturers, adhere to the prescribed safety measures, thereby enhancing overall aviation safety within Australia.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for ensuring the safety of air navigation in Australia. Section 98 of the Act empowers the Governor-General to create regulations that contribute to the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD, as defined in subregulation 39.001(5), is a disallowable instrument under the Acts Interpretation Act 1901 and is considered a legislative instrument as per the Legislative Instruments Act 2003.
The obligations imposed by these provisions include the requirement for CASA to evaluate any airworthiness directives issued by the State of Design, which is the country responsible for the aircraft type's design, and to determine whether to issue an Australian AD that mandates the requirements of the State of Design for aircraft registered in Australia. This process is critical in ensuring that the continuing airworthiness of aircraft is maintained in accordance with international standards set by the International Civil Aviation Organization (ICAO). As the national airworthiness authority, CASA's role is to assess the information provided by the State of Design and issue corresponding ADs to ensure compliance with safety standards.
In terms of enforcement, any breach of the requirements set out in the ADs may result in legal consequences. Although the specific offences, penalties, or consequences for non-compliance are not detailed in the provided text, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 likely include provisions for civil or criminal penalties for non-compliance with ADs. These penalties could include fines, imprisonment, or other sanctions as deemed appropriate by the relevant authorities. The text indicates that CASA issued AD/DH 104/30 for De Havilland DH 104 model aircraft in 1972 and has since decided to cancel it, effective 17 January 2008, due to the original unsafe condition being addressed by another AD. Given that no consultation with the public was necessary and the Office of Best Practice Regulation has deemed a Regulatory Impact Statement unnecessary, the process for cancelling the AD was streamlined, reflecting the reduced regulatory burden and alignment with safety standards.
