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 EASA has issued AD 2008-0205-E affecting Eurocopter AS 350 series helicopters. France is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/ECUREUIL/133, which will become effective on 5 December 2008.
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 Regulatory Review 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, with a primary focus on ensuring the safety of air navigation. This legislation empowers the Governor-General to make regulations that serve the interests of air navigation safety, as exemplified by the Civil Aviation Safety Regulations 1998. Regulation 39.001 of these regulations specifically allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are legislative instruments, disallowable under section 46A of the Acts Interpretation Act 1901, and subject to the requirements of the Legislative Instruments Act 2003. The introduction of ADs is integral to fulfilling Australia's commitments under the Convention on International Civil Aviation, particularly those outlined in Annex 8, which places the responsibility for the continuing airworthiness of aircraft types on the State of Design, while the State of Registry must ensure the continuing airworthiness of individual aircraft. The ADs issued by CASA, such as AD/ECUREUIL/133 in response to EASA's AD 2008-0205-E for Eurocopter AS 350 series helicopters, are a direct outcome of these international obligations and the need to maintain consistent safety standards across contracting states.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) in Australia. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific kinds of aircraft or aeronautical products as a means to ensure the safety of air navigation. This regulatory power is exercised in accordance with Annex 8 to the Convention on International Civil Aviation, which designates the State of Design as having overall responsibility for the continuing airworthiness of an aircraft type. When such a directive is issued by the State of Design, CASA, as Australia's national airworthiness authority, is mandated to assess the information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. This process ensures that Australian aircraft comply with international safety standards. The ADs are considered legislative instruments under the Legislative Instruments Act 2003, and while they are subject to disallowance, they do not require public consultation or a Regulatory Impact Statement, as they are issued in response to international obligations and specific safety concerns identified by the relevant State of Design.
Key Provisions
The Civil Aviation (Safety) Regulations 1998 (regulation 39.001) grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory power is rooted in section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations for the safety of air navigation. The ADs serve as legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. They are critical in maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the design of an aircraft type, must provide necessary information to ensure the aircraft’s continuing airworthiness, and the State of Registry must implement requirements to maintain this airworthiness.
The obligations imposed by these regulations are significant for both CASA and the entities it governs. CASA, as Australia’s national airworthiness authority, must assess ADs issued by the State of Design, such as the European Union Aviation Safety Agency (EASA), and determine if they are applicable to aircraft on the Australian Register. If an AD is deemed necessary, CASA must issue a corresponding Australian AD, ensuring compliance with international standards and domestic regulations. This process underscores the importance of maintaining consistent safety standards across different jurisdictions. Additionally, aircraft operators and owners are required to adhere to the ADs, ensuring that their aircraft meet the necessary safety requirements to operate within Australian airspace.
Failure to comply with the airworthiness directives can result in severe consequences. Under the Civil Aviation Act 1988, non-compliance can lead to civil penalties, including fines up to a specified amount, as well as criminal penalties for more severe breaches. The specific penalties can vary depending on the nature and severity of the non-compliance. CASA has the authority to enforce these regulations, which includes the power to impose fines and take legal action against non-compliant entities. This enforcement mechanism is critical in ensuring that all aircraft operating within Australia meet the necessary safety standards, thereby protecting public safety and maintaining the integrity of the national airspace.
