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/PA-22/17, affecting Piper PA-22 model aircraft, in the 1961. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 3 July 2008. No replacement AD is required, as all affected aircraft would have been modified long ago.
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 Parliament of Australia, aims to provide for the regulation of civil aviation in the interests of safety, efficiency, and economic development. This Act facilitates the establishment of regulations such as the Civil Aviation Safety Regulations 1998, which empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) to ensure the safety of aircraft in Australia. An AD is a legislative instrument under the Legislative Instruments Act 2003, designed to mandate the continuing airworthiness of aircraft types and aeronautical products. The Civil Aviation Act 1988, through its provisions, enables CASA to issue and manage ADs in alignment with international standards set by the International Civil Aviation Organization (ICAO). The objective of these regulations is to ensure that aircraft maintain their airworthiness and comply with safety standards, thereby protecting the public and promoting efficient air navigation.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for particular types of aircraft or aeronautical products, with these directives being legislative instruments subject to disallowance under section 46A of the Acts Interpretation Act 1901. In the context of international obligations, the State of Design is responsible for the continuing airworthiness of an aircraft type, and must share necessary information with the State of Registry to maintain these standards. CASA, as Australia's national airworthiness authority, is required to assess this information and issue Australian ADs as necessary to align with international standards. The application of these regulations is national in scope, applying to all aircraft registered in Australia and to manufacturers and operators within the Australian jurisdiction. The legislative framework allows for the cancellation of ADs when aircraft have been appropriately modified, as in the case of AD/PA-22/17 affecting Piper PA-22 model aircraft, which was cancelled without the need for a replacement due to the completion of required modifications. This cancellation reduces the regulatory burden, and no public consultation or Regulatory Impact Statement was deemed necessary.
Key Provisions
The Civil Aviation (Airworthiness) Regulations 1998 (Cth) empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001. These ADs are intended to mandate safety measures for specific kinds of aircraft or aeronautical products, ensuring they maintain their airworthiness. The authority to issue these directives is derived from section 98 of the Civil Aviation Act 1988, with ADs themselves being classified as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and legislative instruments under section 6 of the Legislative Instruments Act 2003. This regulatory framework is underpinned by international standards set forth in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the overarching responsibility for an aircraft type's continuing airworthiness and mandates the provision of necessary information to the State of Registry.
Obligations imposed by the Act and its regulations on the parties and entities it governs include ensuring that ADs are issued to maintain the continuing airworthiness of aircraft. The State of Design must provide any necessary information to the State of Registry, who is then responsible for developing or adopting requirements to ensure the aircraft's airworthiness. In Australia, CASA, as the national airworthiness authority, must assess information from the State of Design and issue corresponding ADs if necessary. Furthermore, CASA must review and, if deemed appropriate, cancel ADs when the safety issues they address have been sufficiently mitigated. The obligation to assess and act on ADs is clearly delineated in the regulations and supported by international conventions, ensuring a cohesive approach to aircraft safety across jurisdictions.
Failure to comply with ADs can result in severe consequences. Under section 84A of the Civil Aviation Act 1988, CASA has the authority to enforce compliance with ADs, and non-compliance can lead to criminal or civil penalties. The exact nature and severity of these penalties depend on the specifics of the non-compliance and the circumstances surrounding it. Civil penalties can include fines, while criminal penalties might involve imprisonment, reflecting the seriousness with which aviation safety is treated. The regulatory framework is designed to ensure that all stakeholders—including aircraft manufacturers, operators, and maintenance providers—adhere to the highest safety standards to protect the public and maintain the integrity of the aviation system.
