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.
The Civil Aviation Safety Authority or its predecessors issued AD/AA-1/2 affecting Gulfstream AA-1 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-1/2. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, focusing on the safety of air navigation and the maintenance of airworthiness standards. It empowers the Governor-General to make regulations under section 98, which include the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the continuing safety of aircraft. The Civil Aviation Safety Regulations 1998, which were made under the authority of the Act, further detail the process for issuing ADs, which are legislative instruments subject to disallowance and the Legislative Instruments Act 2003. This legislative framework is designed to align with the obligations of Australia under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft and the responsibility of States of Design and Registry.
The specific regulation addressed here involves the cancellation of AD/AA-1/2 for Gulfstream AA-1 model aircraft, reflecting the resolution of the unsafe condition that prompted its issuance. The cancellation of this AD was executed by CASA, as Australia’s national airworthiness authority, without the need for public consultation or a Regulatory Impact Statement, in accordance with the legislative requirements and international obligations under the Convention on International Civil Aviation. The cancellation took effect on 4 June 2009, and no replacement AD is required as the unsafe condition has been resolved. This action was authorised under subsection 84A(2) of the Act and executed by the Manager, Systems and New Technologies, within CASA's Airworthiness Engineering Group.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft types registered in Australia. These directives apply to the types of aircraft or aeronautical products specified within the ADs and mandate compliance with safety requirements to ensure the continuing airworthiness of these aircraft. The authority to issue ADs is grounded in the obligations of Australia under the Convention on International Civil Aviation, where the State of Design has the responsibility to provide information to States of Registry to ensure aircraft safety. CASA, as Australia’s national airworthiness authority, assesses this information and, if necessary, issues corresponding ADs for Australian-registered aircraft. The ADs are considered legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The specific AD/AA-1/2, affecting Gulfstream AA-1 model aircraft, was assessed by CASA and subsequently cancelled as the unsafe condition it was addressing no longer exists, effective from 4 June 2009. The cancellation of this AD was made without public consultation and does not require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to make regulations necessary for the safety of air navigation, enabling the Civil Aviation Safety Regulations 1998 (regulation 39.001) to permit the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). An AD is a legislative instrument that can be disallowed under the Acts Interpretation Act 1901 (section 46A) and is subject to the provisions of the Legislative Instruments Act 2003 (section 6). These directives are crucial for maintaining the continuing airworthiness of aircraft types, as outlined in Annex 8 to the Convention on International Civil Aviation, which assigns the State of Design responsibility for providing necessary information to States of Registry. The State of Registry, in turn, must ensure the continuing airworthiness of individual aircraft by adopting or developing appropriate requirements.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 necessitate that CASA assess any ADs issued by the State of Design that affect aircraft on the Australian Register. If deemed necessary, CASA issues an Australian AD to enforce the requirements specified by the State of Design. This process ensures compliance with international standards and maintains the safety of air navigation within Australia. The specific AD/AA-1/2, which was affecting Gulfstream AA-1 model aircraft, has been assessed by CASA and subsequently cancelled as of 4 June 2009. This cancellation was based on the resolution of the unsafe condition and does not require a replacement AD.
Failure to comply with ADs can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can include imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the Act. CASA's authority to issue ADs and enforce compliance is critical in maintaining the high standards of aviation safety required under both national and international law.
