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-23/32 Amendment 2 affecting Piper PA-23 model aircraft in 1962. 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 was enacted to establish a comprehensive regulatory framework for civil aviation safety in Australia, addressing the need for a unified and effective approach to the safety of air navigation. This legislation empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, which include provisions for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are crucial for maintaining the continuing airworthiness of aircraft, in line with international standards set by the Convention on International Civil Aviation. The Act's overarching policy objective is to ensure the safety of air navigation through rigorous regulatory oversight, thereby protecting the public and maintaining the integrity of Australia's civil aviation system.
The cancellation of AD/PA-23/32 Amendment 2, effective 3 July 2008, exemplifies CASA's role in managing the regulatory burden and ensuring that outdated directives are removed without impacting current safety standards. This action was taken without public consultation, as it was deemed to reduce the regulatory burden, and no Regulatory Impact Statement was required, as determined by the Office of Best Practice Regulation. This process underscores the authority vested in CASA to manage airworthiness directives efficiently, ensuring that the regulatory framework remains responsive and effective in addressing safety concerns.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. These regulations apply to aircraft registered in Australia, their owners, operators, and maintenance providers, as well as to aeronautical products used on such aircraft. The issuance of ADs is intended to address safety concerns and ensure the continuing airworthiness of aircraft types registered in Australia. These regulations have a national jurisdictional reach, as they pertain to all aircraft registered in Australia, irrespective of where they are manufactured or operated. There are no specific exclusions mentioned in the text; however, it is implied that the ADs would not apply to aircraft that are not registered in Australia. The authority to issue ADs is extended through subordinate instruments, where CASA, as Australia's national airworthiness authority, assesses information from the State of Design and issues Australian ADs accordingly. The ADs are legislative instruments subject to disallowance and review as stipulated by the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations for the purposes of the Act, particularly in relation to the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 provides the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and consequently, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. These ADs are integral to ensuring the continuing airworthiness of aircraft types, aligning with the obligations set forth in Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design, who must provide necessary information to the States of Registry.
The obligations imposed by the Civil Aviation Safety Regulations 1998 on parties governed by these provisions include the requirement for CASA, as the national airworthiness authority, to assess and potentially issue Australian ADs when a State of Design issues a directive affecting aircraft on the Australian Register. This ensures that the safety standards and maintenance requirements are uniformly enforced across the country. The State of Registry of an aircraft must also develop or adopt requirements to ensure the continuing airworthiness of the aircraft under its jurisdiction. These obligations are essential to maintain a consistent and high standard of aviation safety.
The Civil Aviation Safety Regulations 1998 do not explicitly detail specific offences or penalties for non-compliance with ADs. However, non-compliance with ADs can lead to significant civil and criminal consequences. Under section 75 of the Civil Aviation Act 1988, an aircraft is deemed not airworthy if it does not comply with an AD, which can result in enforcement actions by CASA. Such actions may include fines, suspension or revocation of airworthiness certificates, and potential criminal charges for operators who fail to adhere to the mandated safety requirements. The maximum penalties for these offences can vary, but they are severe enough to ensure compliance with airworthiness directives to maintain the highest safety standards in the aviation industry.
