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/FU24/57 affecting Fletcher FU24 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/FU24/57. The cancellation will become effective on 7 May 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, Airframes and Structures, 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 a comprehensive framework for the regulation of civil aviation in Australia, ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to make regulations that serve the interests of air navigation safety, as exemplified by the Civil Aviation Safety Regulations 1998. Specifically, regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for various types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft and are considered legislative instruments under the Legislative Instruments Act 2003. The policy objective of these regulations aligns with international standards set by the Convention on International Civil Aviation, where the State of Design and the State of Registry share responsibilities for ensuring the safety of aircraft. In light of these international obligations, CASA issued and subsequently cancelled AD/FU24/57 concerning the Fletcher FU24 model aircraft, reflecting Australia's commitment to safety standards and international cooperation in aviation regulation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 collectively provide the framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) to ensure the safety of air navigation. The Act empowers the Governor-General to make regulations concerning the safety of air navigation, while the Regulations allow CASA to issue ADs for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and are created in compliance with the Legislative Instruments Act 2003. The ADs are issued in accordance with international standards under Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of an aircraft type, with the State of Registry tasked with ensuring the airworthiness of individual aircraft. CASA, as the national airworthiness authority, must issue Australian ADs when necessary to implement the requirements set by the State of Design. The cancellation of AD/FU24/57 for Fletcher FU24 model aircraft, effective from 7 May 2009, exemplifies the process by which CASA addresses safety concerns by assessing and potentially cancelling ADs if the unsafe conditions no longer exist, without necessitating public consultation or a Regulatory Impact Statement.
Key Provisions
The key operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 pertain to the issuance of airworthiness directives (ADs) under section 98 of the Act and regulation 39.001 of the Regulations. Specifically, regulation 39.001(5) identifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, making it a legislative instrument under section 6 of the Legislative Instruments Act 2003. The Civil Aviation Authority (CASA) has the authority to issue such ADs for specific kinds of aircraft or aeronautical products. Furthermore, the State of Design, which holds overall responsibility for the continuing airworthiness of an aircraft type, must provide any necessary information to the appropriate States of Registry to ensure the continuing airworthiness of the type. This is in accordance with Annex 8 to the Convention on International Civil Aviation.
The Act and Regulations impose several obligations and requirements on the parties and entities they govern. The State of Design must provide continuing airworthiness information, and the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When an AD is issued by the State of Design, CASA must assess the information and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that the Australian aircraft fleet remains compliant with international airworthiness standards. The obligations also extend to the cancellation of ADs when the unsafe condition no longer exists, as seen in the case of AD/FU24/57 affecting Fletcher FU24 model aircraft, which CASA assessed and subsequently cancelled on 7 May 2009.
The Act and Regulations also detail the civil and criminal consequences for breaches. Although specific penalties are not outlined in the provided text, it is clear that failure to comply with ADs or to ensure the continuing airworthiness of aircraft can result in significant consequences. These may include fines, imprisonment, or other civil or criminal penalties as prescribed by the relevant legislation. It is important for entities governed by the Act and Regulations to adhere to the issued ADs and to implement the necessary requirements to avoid any potential legal repercussions.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for the issuance and enforcement of airworthiness directives to ensure the safety of air navigation. The key sections and regulations require the States of Design and Registry to provide and implement continuing airworthiness information, with CASA playing a pivotal role in assessing and issuing Australian ADs. The obligations and requirements ensure compliance with international standards, while the potential civil and criminal consequences serve as a deterrent against non-compliance.
