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 2006-0320-E affecting a single Dassault Aviation Falcon 2000EX aircraft. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/F2000/28, which will become effective on 20 December 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 provide a legal framework for civil aviation in Australia, ensuring the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations, including those pertaining to airworthiness, to safeguard the interests of air navigation safety. Under section 98 of this Act, the Civil Aviation Safety Regulations 1998 were subsequently introduced, establishing the legal basis for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations mandate that CASA can issue ADs for specific kinds of aircraft or aeronautical products to maintain or ensure airworthiness. In line with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, the State of Design retains overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must ensure the continuing airworthiness of individual aircraft. This legislative framework allows CASA to issue Australian ADs in response to ADs issued by other countries’ authorities, such as the European Aviation Safety Agency, thereby fulfilling Australia's international obligations and ensuring the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for the issuance of airworthiness directives (ADs) in Australia, overseen by the Civil Aviation Safety Authority (CASA). Under these regulations, CASA has the authority to issue ADs for specific types of aircraft or aeronautical products to ensure compliance with airworthiness standards. The ADs serve as legislative instruments under the Acts Interpretation Act 1901 and are necessary to meet the obligations of Australia under the Convention on International Civil Aviation, particularly concerning continuing airworthiness. This regulatory approach ensures that aircraft registered in Australia conform to international safety standards, especially when directives are issued by the State of Design, such as the European Aviation Safety Authority (EASA) for certain aircraft types. The issuance of an Australian AD, such as AD/F2000/28 for a Dassault Aviation Falcon 2000EX aircraft, is a direct response to a corresponding AD from the relevant State of Design and is implemented without public consultation as mandated by the convention and Australian law.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to enact regulations that serve the purpose of the Act and the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures that safety measures are consistently implemented across the aviation industry. Moreover, subregulation 39.001(5) designates ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901, thereby classifying them as legislative instruments according to section 6 of the Legislative Instruments Act 2003.
These airworthiness directives serve as a mechanism for ensuring that aircraft maintain their airworthiness over time. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type. This includes the obligation to provide any necessary information to the States of Registry to maintain the airworthiness of the aircraft. In response to this international obligation, the State of Registry must develop or adopt its own requirements to ensure the continuing airworthiness of aircraft within its jurisdiction. When a State of Design, such as France through the European Aviation Safety Authority (EASA), issues an AD, CASA, as Australia’s national airworthiness authority, must assess this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design.
The obligations imposed by these regulations are stringent and multifaceted. The State of Design must ensure that the aircraft type remains airworthy and must communicate any necessary safety information to the States of Registry. The State of Registry, in this case CASA, must then assess the AD issued by the State of Design and, if deemed necessary, issue an Australian AD to mandate compliance. This ensures that all aircraft registered in Australia meet the required safety standards. Given the global nature of aviation, these obligations underscore the importance of international cooperation and compliance to ensure safety and uniformity in aviation practices.
Failure to comply with the provisions set out in these airworthiness directives can lead to significant consequences. While the specific offences, penalties, or consequences are not detailed in the provided text, it is clear that non-compliance with ADs can result in serious legal ramifications. In Australia, CASA has the authority to enforce compliance, and breaches can lead to enforcement actions, fines, or other penalties. Additionally, non-compliance may result in the grounding of aircraft, which can have substantial operational and financial impacts on the operators. The regulatory framework is designed to ensure that all parties adhere to the highest safety standards to protect the public and maintain the integrity of the aviation industry.
