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/BEECH 56/10, affecting Beech 56 model aircraft in 1971. 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 was enacted to regulate civil aviation in Australia, ensuring safety and efficiency within the industry. This Act empowers the Governor-General to establish regulations that support the Act's objectives, particularly concerning the safety of air navigation. One such regulation is detailed in the Civil Aviation Safety Regulations 1998, which allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products. These directives are legislative instruments and serve as crucial tools for maintaining the airworthiness of aircraft, in line with international standards set by the Convention on International Civil Aviation. The Act aims to uphold the highest safety standards in Australian civil aviation by allowing CASA to mandate necessary safety measures through ADs, ensuring that the regulatory burden is reduced where appropriate.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the overarching Civil Aviation Act 1988, provides the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. This legislation applies to all persons and entities involved in the design, manufacture, and operation of aircraft within Australia, including aircraft operators, manufacturers, and maintenance providers. The scope of the Act extends to all aircraft registered in Australia and to aeronautical products used in or on aircraft. The application of the ADs is geographically confined to Australia, reflecting its national jurisdiction. However, these directives are also aligned with the standards set by the International Civil Aviation Organization (ICAO), ensuring that Australian aviation safety practices are consistent with global standards. Any AD issued under these regulations is a disallowable instrument, subject to scrutiny and potential disallowance by Parliament. The process for issuing, reviewing, and cancelling ADs, as exemplified by the recent cancellation of AD/BEECH 56/10, is designed to respond efficiently to emerging safety concerns while reducing regulatory burden where appropriate.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus constitutes a legislative instrument as per section 6 of the Legislative Instruments Act 2003. These regulations are in line with Annex 8 of the Convention on International Civil Aviation, which stipulates that the State of Design holds overall responsibility for the continuing airworthiness of an aircraft type, including the provision of necessary information to the States of Registry.
Under these regulations, the State of Design is obligated to ensure the continuing airworthiness of aircraft types, while the State of Registry, which is responsible for individual aircraft, must establish or adopt requirements to maintain airworthiness. For example, when a State of Design issues an AD concerning an aircraft type registered in Australia, CASA, as the national airworthiness authority, must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements. In the case of AD/BEECH 56/10, which affected Beech 56 model aircraft from 1971, CASA has determined the AD should be cancelled, effective from 17 January 2008. This decision was made after a review revealed that the original safety concern is now addressed by AD/GENERAL/74 Amendment 1, and no replacement AD is needed.
Compliance with these provisions involves several obligations for the parties involved. CASA must ensure that any ADs issued align with international standards and adequately address safety concerns. Similarly, the States of Design and Registry must cooperate in sharing necessary information to maintain airworthiness. For instance, the State of Design must provide timely and accurate information to the State of Registry, which in turn must implement the necessary measures to ensure the safety of the aircraft it registers. Moreover, aircraft operators must comply with the ADs applicable to their aircraft by implementing the required actions within specified timeframes.
Failure to comply with the ADs can lead to various consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can be considered an offence, potentially resulting in civil or criminal penalties. While the specific penalties are not detailed in the provided text, it is established that breaches of regulations concerning airworthiness can attract significant sanctions. The severity of these penalties reflects the critical importance of adhering to airworthiness directives in maintaining the safety of air navigation.
