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/A109/13 affecting Agusta A109 series helicopters. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective 27 August 2009. No replacement AD is required, as the original unsafe condition no longer exists.
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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation within the country. One of the significant aspects of this legislation is the ability of the Governor-General to make regulations under section 98 for the purposes of the Act, particularly focusing on the safety of air navigation. The Civil Aviation Safety Regulations 1998, which are made under the authority of the Act, include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs serve as legislative instruments to maintain the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO).
The cancellation of AD/A109/13, which affected Agusta A109 series helicopters, exemplifies the regulatory process within this framework. CASA issued the AD in response to identified unsafe conditions but, after a review, determined that the unsafe condition no longer existed, leading to the cancellation of the directive effective 27 August 2009. This action underscores CASA's commitment to safety while also reflecting the efficiency of the regulatory process in reducing unnecessary burdens. The cancellation of this AD was made under the authority of the Act, ensuring that CASA's actions align with the overarching policy objective of maintaining the highest standards of aviation safety in Australia.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, thereby ensuring the safety of air navigation as outlined in the Civil Aviation Act 1988. These directives are critical for maintaining the continuing airworthiness of aircraft and are issued in accordance with Annex 8 of the Convention on International Civil Aviation. Each State of Registry, including Australia through CASA, is tasked with the responsibility of ensuring that aircraft under their registry meet the necessary airworthiness standards. In the case of the AD/A109/13, CASA issued a directive affecting Agusta A109 series helicopters, which has since been reviewed and cancelled, effective 27 August 2009, due to the resolution of the original safety concerns. The cancellation of this AD does not require public consultation or a Regulatory Impact Statement, as it reduces the regulatory burden. CASA’s decision to cancel the AD was made by the Manager, Future Technology and Regulatory Trends, in accordance with subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 contain the primary provisions governing airworthiness directives (ADs) in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore they are legislative instruments. ADs serve as a critical mechanism for ensuring the continuing airworthiness of aircraft, in line with Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design the responsibility for an aircraft type’s airworthiness and requires it to provide necessary information to States of Registry.
The obligations under these regulations require CASA to assess ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs. The State of Registry, which in this case is Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft on its register. For instance, CASA issued AD/A109/13 for Agusta A109 series helicopters. However, after reviewing the directive, CASA decided to cancel it, effective from 27 August 2009, as the original unsafe condition no longer existed. This cancellation was made without public consultation, as it reduces the regulatory burden, and it was determined by the Office of Best Practice Regulation that ADs do not require a Regulatory Impact Statement.
Any breach of ADs can lead to serious consequences. ADs are legally binding, and failure to comply can result in enforcement actions against individuals and entities. While specific offences and penalties are not detailed in the provided text, it is clear that non-compliance with ADs could result in civil or criminal penalties. The exact nature and severity of these penalties would depend on the specific circumstances and the provisions of other relevant legislation. CASA, as the national airworthiness authority, would be responsible for enforcing these directives and taking appropriate action against those who do not comply.
