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-28/39 affecting Piper PA-28 model aircraft in 1972. 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 inspected, and, if necessary, 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 was enacted to provide a comprehensive legal framework for the regulation of civil aviation in Australia, aiming to ensure safety and efficiency in air navigation. Among its provisions, the Act empowers the Governor-General to make regulations necessary for the interests of air navigation safety. The Civil Aviation Safety Regulations 1998 further specify how these regulations are to be implemented, including the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives serve as crucial tools for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). The cancellation of an existing AD for Piper PA-28 model aircraft, effective 3 July 2008, demonstrates CASA’s ongoing commitment to ensuring that regulatory measures are both necessary and effective, without unnecessary burden on the industry or the public.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs, which are legislative instruments under the Acts Interpretation Act 1901, are integral to maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which holds primary responsibility for the airworthiness of an aircraft type, must provide necessary information to the State of Registry, which is then required to ensure the aircraft's ongoing compliance with airworthiness standards. CASA, as Australia’s national airworthiness authority, must assess and, if necessary, issue Australian ADs to reflect the requirements of the State of Design. This legislative framework applies to all aircraft registered in Australia and those subject to Australian regulatory oversight, thereby extending its reach to all relevant entities and individuals within the aviation industry. The ADs may be amended or cancelled through subordinate instruments as circumstances warrant, such as when CASA cancels an existing AD after reviewing its necessity, as demonstrated by the cancellation of AD/PA-28/39 for Piper PA-28 model aircraft effective from 3 July 2008.
Key Provisions
The Civil Aviation Act 1988 provides the overarching legal framework for aviation safety in Australia, and under section 98, the Governor-General is empowered to create regulations in the interest of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. These ADs are legislative instruments under section 6 of the Legislative Instruments Act 2003, and they serve as the primary means by which states communicate continuing airworthiness information, as stipulated in Annex 8 to the Convention on International Civil Aviation.
Under the Civil Aviation Safety Regulations 1998, CASA is mandated to assess any ADs issued by the State of Design regarding aircraft types on the Australian Register and to issue corresponding Australian ADs if necessary. This ensures that the continuing airworthiness requirements of the State of Design are met within Australia. For example, CASA issued AD/PA-28/39 in 1972 for Piper PA-28 model aircraft, but has since reviewed and decided to cancel this AD, effective from 3 July 2008. This cancellation is due to the fact that all affected aircraft would have already been inspected and modified, if necessary, long ago. Consequently, no replacement AD is required, and no consultation with the Australian public was deemed necessary as it results in a reduction of the regulatory burden.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on CASA and other relevant entities include the assessment and potential issuance of Australian ADs when required, ensuring compliance with international standards set by ICAO, and maintaining the continuing airworthiness of aircraft registered in Australia. States of Design must also provide necessary information to ensure the continuing airworthiness of aircraft types. Failure to comply with these obligations could lead to non-compliance with international aviation safety standards, potentially impacting the safety and airworthiness of affected aircraft.
Breaching the obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can result in various civil and criminal consequences. While specific penalties are not detailed in the provided text, non-compliance with ADs can lead to serious safety risks, and could potentially result in enforcement actions by CASA, including fines or other civil penalties. Additionally, more severe breaches might lead to criminal charges, particularly if they result in significant safety incidents or violations. The exact penalties would depend on the nature and severity of the breach, as well as any resulting harm or risk.
