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/BELL 412/14 amendment 1 affecting Bell 412 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 9 April 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, 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 a comprehensive framework for the regulation of civil aviation in Australia, addressing the need for safety and efficiency in air navigation. The Act empowers the Governor-General to make regulations that ensure the safety of air navigation, and it establishes the Civil Aviation Safety Authority (CASA) as the regulatory body responsible for the implementation and enforcement of these regulations. One of the key tools CASA utilises under the Act is the issuance of airworthiness directives (ADs), which are legislative instruments aimed at ensuring the continuing airworthiness of aircraft. These ADs are issued in accordance with Annex 8 to the Convention on International Civil Aviation, reflecting Australia’s commitment to international standards and practices. The Civil Aviation Safety Regulations 1998 further detail the procedures and responsibilities related to the issuance and management of ADs, ensuring that both the State of Design and the State of Registry play their respective roles in maintaining aircraft airworthiness. The policy objective of these measures is to enhance the safety of air navigation by providing clear, enforceable directives that address identified safety issues.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for issuing airworthiness directives (ADs) in Australia, which are legislative instruments designed to maintain the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products, thereby ensuring compliance with safety standards and international obligations under the Convention on International Civil Aviation. These ADs serve as crucial tools for the State of Registry to maintain the continuing airworthiness of aircraft registered within Australia. In line with Australia’s commitments under the Convention, CASA has the authority to cancel existing ADs, as evidenced by the cancellation of AD/BELL 412/14 amendment 1 for Bell 412 aircraft, effective from 9 April 2009, with no requirement for a replacement directive. This legislative action is taken without public consultation and does not necessitate a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Group at CASA, in accordance with the provisions of the Civil Aviation Act 1988.
Key Provisions
The primary operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are section 98 and regulation 39.001, respectively. Section 98 allows the Governor-General to make regulations aimed at ensuring the safety of air navigation, while regulation 39.001 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. Under subregulation 39.001(5), these ADs are considered disallowable instruments under the Acts Interpretation Act 1901, and therefore, legislative instruments as per the Legislative Instruments Act 2003.
The Civil Aviation Safety Regulations 1998 impose several obligations on CASA and other parties. CASA must ensure the continuing airworthiness of aircraft through the issuance of ADs, which are intended to provide necessary information for maintaining the safety of aircraft in operation. Additionally, the State of Registry of an individual aircraft is responsible for ensuring the aircraft's continuing airworthiness, while the State of Design must provide any information necessary to ensure the airworthiness of the aircraft type. These obligations are in line with the requirements set out in Annex 8 to the Convention on International Civil Aviation.
There are specific consequences for non-compliance with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. While the Act does not explicitly state penalties for non-compliance, failure to adhere to ADs could result in the grounding of non-compliant aircraft, which would have severe implications for the safety and operation of the aircraft. Non-compliance with the Convention on International Civil Aviation could lead to international safety concerns and potential sanctions from other contracting states.
In summary, the key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 focus on ensuring the safety of air navigation through the issuance of ADs and the maintenance of airworthiness of aircraft. CASA is responsible for issuing ADs and ensuring compliance, while the State of Registry and State of Design must also meet their respective obligations to ensure the continuing airworthiness of aircraft. Non-compliance with these provisions could lead to severe consequences, including the grounding of non-compliant aircraft and international safety concerns.
