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 European Aviation Safety Authority (EASA) has issued AD 2007-0259-E affecting Eurocopter AS 365, SA 365 and SA 366 model helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DAUPHIN/93, which will become effective on 03 October 2007.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation and the continuing airworthiness of aircraft. This Act empowers the Governor-General to create regulations, including airworthiness directives, for the protection of air navigation safety, as per section 98. The Civil Aviation Safety Regulations 1998 further delineate the powers and procedures for issuing airworthiness directives, which are critical tools for maintaining the safety standards of aircraft and aeronautical products, as outlined in regulation 39.001. These directives are classified as legislative instruments under the Legislative Instruments Act 2003, reflecting their importance in the regulatory landscape. The Act was introduced to address the need for a comprehensive legislative approach to managing the complexities of civil aviation, ensuring that Australian aviation practices align with international standards and obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the safety and airworthiness of aircraft within Australian airspace. Specifically, the Act empowers the Governor-General to make regulations aimed at ensuring the safety of air navigation, with regulation 39.001 allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs serve as legislative instruments under the Legislative Instruments Act 2003, reflecting their importance in maintaining safety standards. The application of these directives is influenced by international obligations under the Convention on International Civil Aviation, where the State of Design retains responsibility for the continuing airworthiness of an aircraft type, necessitating information sharing with States of Registry like Australia. CASA, as Australia's national airworthiness authority, must issue corresponding Australian ADs when required, ensuring compliance with international standards and maintaining the safety of aircraft registered in Australia. The issuance of ADs, such as the one concerning Eurocopter AS 365, SA 365, and SA 366 model helicopters, exemplifies the implementation of these regulations, reflecting Australia's commitment to international safety standards without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to create regulations aimed at ensuring the safety of air navigation. These regulations can encompass various aspects of aviation, including the issuance of airworthiness directives (ADs) as detailed in regulation 39.001 of the Civil Aviation Safety Regulations 1998. An AD is a legislative instrument that the Civil Aviation Safety Authority (CASA) can issue for specific types of aircraft or aeronautical products. According to subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and they must be reviewed and approved in accordance with the Legislative Instruments Act 2003. These directives are pivotal in maintaining the continuing airworthiness of aircraft as mandated by Annex 8 to the Convention on International Civil Aviation.
The obligations under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to play a crucial role in ensuring the safety of aircraft registered in Australia. When a State of Design, such as France in the case of Eurocopter AS 365, SA 365, and SA 366 model helicopters, issues an AD, CASA must assess this information to determine its applicability to aircraft registered in Australia. If deemed necessary, CASA issues its own AD to mandate compliance with the requirements specified by the State of Design. This process ensures that the airworthiness standards are consistent and aligned with international safety norms. The State of Registry, which in this context is Australia, is responsible for implementing these directives to ensure the continuing airworthiness of the aircraft under its jurisdiction.
In the case of Eurocopter AS 365, SA 365, and SA 366 model helicopters, the European Aviation Safety Authority (EASA) issued AD 2007-0259-E, prompting CASA to issue Australian AD/DAUPHIN/93. This AD, which came into effect on 3 October 2007, is a direct response to international obligations under the Convention on International Civil Aviation and the specific AD issued by the State of Design. Given the nature of these directives, there was no requirement for public consultation as per the provisions of the legislation. Furthermore, the Office of Best Practice Regulation has determined that such ADs do not necessitate a Regulatory Impact Statement. The AD was issued by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The legislation also outlines potential consequences for non-compliance with ADs. While the specific penalties are not detailed in the excerpt, it is implied that failure to adhere to the requirements of an AD could result in legal and operational repercussions. The regulatory framework is designed to ensure that all parties, including aircraft operators and maintenance providers, comply with the stipulated airworthiness standards to prevent any compromise to flight safety. The issuance and enforcement of ADs are critical components of the regulatory environment aimed at maintaining the highest safety standards in civil aviation.
