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/ECUREUIL/35 affecting Eurocopter AS350 helicopters. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 30 July 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, enacted by the Australian Parliament, was introduced to ensure the safety of air navigation, among other things. This Act empowers the Governor-General to make regulations for the purposes of the Act, and section 98 specifically allows the creation of regulations that are in the interests of the safety of air navigation. Complementing the Act are the Civil Aviation Safety Regulations 1998, under which the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as a key mechanism for maintaining the continuing airworthiness of aircraft, aligning with international standards set by the International Civil Aviation Organization (ICAO). This legislative framework ensures that Australia meets its obligations under the Convention on International Civil Aviation, particularly regarding the responsibility of the State of Registry and the State of Design in ensuring the safety and airworthiness of aircraft. The cancellation of a specific airworthiness directive, as in the case of AD/ECUREUIL/35 affecting Eurocopter AS350 helicopters, reflects the ongoing commitment to safety and compliance with international obligations.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products. This regulation is made under the authority of the Civil Aviation Act 1988 and is designed to enhance the safety of air navigation, thereby ensuring that all aircraft and aeronautical products meet specific safety standards. The ADs serve as a legislative instrument and are subject to disallowance under the Acts Interpretation Act 1901. The ADs are aligned with Annex 8 of the Convention on International Civil Aviation, which stipulates that the State of Design bears responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. The cancellation of an AD, such as the one issued for Eurocopter AS350 helicopters, is made by the Manager, Airframes and Structures in the Airworthiness Engineering Group on behalf of CASA, and it adheres to the provisions outlined in subsection 84A(2) of the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for ensuring the safety of air navigation in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (sections 98 and 39.001). These directives are considered legislative instruments under the Legislative Instruments Act 2003 (section 6). This legislative framework aligns with the requirements of Annex 8 to the Convention on International Civil Aviation, which places responsibility for the continuing airworthiness of aircraft types on the State of Design and on the State of Registry for individual aircraft.
The obligations under this legislation are multifaceted. The State of Design is tasked with providing necessary information to ensure the continuing airworthiness of an aircraft type, while the State of Registry must develop or adopt requirements to maintain this airworthiness (Annex 8). CASA, as the regulatory authority in Australia, has the power to issue ADs, which are essential for maintaining safety standards. The cancellation of an AD, such as AD/ECUREUIL/35 affecting Eurocopter AS350 helicopters, reflects Australia's commitment to international safety standards and the obligations under the Convention on International Civil Aviation.
Failing to comply with ADs can lead to significant consequences. The Act does not explicitly state offences or penalties for non-compliance with ADs; however, general provisions in the Civil Aviation Act 1988 may apply, which could include fines and imprisonment for serious violations affecting aviation safety. Additionally, non-compliance could result in the grounding of aircraft, which could have severe operational and financial repercussions for operators. Given the critical nature of airworthiness, regulatory bodies such as CASA may take stringent actions to ensure compliance with safety directives.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a comprehensive framework for ensuring the safety of air navigation in Australia. CASA has the authority to issue ADs, which are crucial for maintaining the airworthiness of aircraft. The obligations of States of Design and Registry under international conventions are mirrored in Australian law, with CASA playing a pivotal role in enforcing these standards. Non-compliance with ADs can result in significant penalties and operational disruptions, highlighting the importance of adhering to these safety directives.
