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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/R22/6 affecting Robinson R22 helicopters. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 7 May 2009. No replacement AD is required.
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 regulate the safety of civil aviation in Australia, ensuring the safety of air navigation and the continuing airworthiness of aircraft. Under section 98 of this Act, the Governor-General has the authority to make regulations, which in this context includes the issuance of airworthiness directives (ADs) to maintain aircraft safety standards. The Civil Aviation Safety Regulations 1998 further empower the Civil Aviation Safety Authority (CASA) to issue such directives for specified kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003, as they are disallowable instruments as defined in the Acts Interpretation Act 1901. The authority to issue these directives stems from Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design and the State of Registry both play roles in ensuring the continuing airworthiness of aircraft. CASA, acting on behalf of the Australian Government, has the responsibility to issue and manage these directives to comply with international standards and to protect public safety within Australian airspace.
Scope and Application
The Civil Aviation Safety Regulations 1998, under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs are legislative instruments, as stipulated in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. In accordance with Annex 8 to the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, is responsible for the airworthiness of individual aircraft. ADs serve as a primary means of ensuring the continuing airworthiness of aircraft types and are issued by most ICAO Contracting States. CASA's issuance and subsequent cancellation of AD/R22/6 for Robinson R22 helicopters reflects the authority's adherence to international obligations and its commitment to safety standards. The cancellation of this AD, effective from 7 May 2009, was made by the Manager, Airframes and Structures in the Airworthiness Engineering Group on behalf of CASA, in compliance with subsection 84A(2) of the Act, and no public consultation or Regulatory Impact Statement was required as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, sets out the framework for the regulation of civil aviation safety in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in the interests of air navigation safety. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, as stated in section 46A of the Acts Interpretation Act 1901 and confirmed by subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998. These regulations ensure that the State of Design and the State of Registry bear the primary responsibility for the continuing airworthiness of aircraft types and individual aircraft, respectively, as outlined in Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by these provisions require CASA to issue ADs to address safety issues in aircraft or aeronautical products, ensuring compliance with safety standards. The State of Design must provide necessary information to the States of Registry to maintain airworthiness. The State of Registry, in turn, must establish and enforce requirements to ensure the ongoing airworthiness of aircraft within its jurisdiction. These requirements ensure that aircraft remain safe and airworthy throughout their operational lives. The provisions also require CASA to review and, if necessary, cancel ADs, such as AD/R22/6 affecting Robinson R22 helicopters, to reflect the most current and accurate safety information.
Failure to comply with ADs can result in significant consequences. Operators who do not adhere to the mandates set forth in ADs may face enforcement actions, including fines, legal penalties, and potential criminal charges. The specific penalties for non-compliance can vary but may include substantial monetary fines and imprisonment, depending on the severity of the violation. The regulations emphasise the importance of adhering to ADs to maintain the highest safety standards in civil aviation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for ensuring the safety of civil aviation in Australia. The issuance of ADs by CASA, the responsibilities of the State of Design and the State of Registry, and the consequences of non-compliance are all integral to maintaining the safety and airworthiness of aircraft. These provisions reflect Australia’s commitment to international aviation safety standards and the practical application of these standards within the country.
