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 55/1, affecting Beech 55 model aircraft in 1961. CASA has reviewed this AD and as a result has decided to cancel it. The cancellation will become effective on 5 June 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 regulate civil aviation in Australia, focusing on the safety of air navigation. Under this Act, the Governor-General has the authority to make regulations that serve the interests of safety in air navigation, as highlighted in section 98. Complementing this, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures that aircraft maintain their airworthiness throughout their operational life, aligning with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act thus provides the legislative foundation for maintaining high safety standards in Australia's civil aviation sector, ensuring that the continuing airworthiness of aircraft is rigorously overseen.
Scope and Application
The Civil Aviation Act 1988 provides the legislative framework for the regulation of civil aviation in Australia, and the Civil Aviation Safety Regulations 1998 detail specific safety requirements. The Act applies to persons and entities involved in civil aviation activities, including aircraft manufacturers, operators, and maintenance organisations, within Australia's jurisdictional boundaries. The Act is administered by the Civil Aviation Safety Authority (CASA), which issues airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998 to ensure the safety of air navigation. These directives are legislative instruments and must adhere to the requirements of the Legislative Instruments Act 2003. The ADs are typically issued in response to safety concerns identified by the State of Design or Registry, and CASA is responsible for ensuring that Australian-registered aircraft meet the necessary airworthiness standards. The AD/BEECH 55/1, affecting Beech 55 model aircraft from 1961, is an example of such a directive. Following a review, CASA has decided to cancel this AD as it no longer imposes a regulatory burden, and all necessary modifications have been completed. This cancellation does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) allow the Governor-General to make regulations for the safety of air navigation, and the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is considered a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and a legislative instrument under section 6 of the Legislative Instruments Act 2003, as per subregulation 39.001(5). These directives ensure that aircraft maintain their airworthiness, following the guidance provided by Annex 8 to the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require the State of Design to provide necessary information to ensure the continuing airworthiness of aircraft types, while the State of Registry must develop or adopt requirements for the continuing airworthiness of individual aircraft. In Australia, CASA must assess the information provided by the State of Design and issue an Australian AD if appropriate. This ensures that the requirements of the State of Design are met and the airworthiness of aircraft on the Australian Register is maintained.
Failure to comply with the ADs may result in various consequences. Aircraft found not to be in compliance with the mandated requirements may be deemed unairworthy, which can lead to the grounding of the aircraft. This can result in significant financial losses for operators, as well as potential criminal charges for those responsible for the non-compliance. The maximum penalties for breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 can include fines and imprisonment. The exact penalties depend on the severity of the breach and are determined by the courts.
CASA issued AD/BEECH 55/1, which affected Beech 55 model aircraft from 1961, and has since decided to cancel it, effective 5 June 2008. This cancellation was made without public consultation, as it 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 cancellation was made by the Manager, Airframes, in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
