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 2007-0269 affecting Airbus A330 model aircraft. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A330/80, which will become effective on 24 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, enacted by the Australian Parliament, is a pivotal piece of legislation designed to ensure the safety and efficiency of air navigation within Australia. The Act empowers the Governor-General to establish regulations, including those that pertain to airworthiness directives, which are essential for maintaining the safety standards of aircraft and aeronautical products. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) has the authority to issue these directives, ensuring that all aircraft on the Australian Register meet the required safety standards. This legislative framework is vital for Australia’s compliance with the Convention on International Civil Aviation, particularly in terms of the responsibilities of the State of Design and State of Registry regarding the continuing airworthiness of aircraft. The issuance of an Australian airworthiness directive, such as AD/A330/80 in response to an equivalent directive by the European Aviation Safety Authority, underscores the importance of international cooperation in maintaining global aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. This authority is exercised under the overarching framework of the Civil Aviation Act 1988. These ADs serve as legislative instruments, which must be assessed and, if deemed appropriate, mandated by CASA to ensure compliance with international standards of airworthiness. The geographic reach of these regulations is national, applying to all aircraft registered within Australia, and international, as they adhere to the Convention on International Civil Aviation. This convention designates the State of Design with the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry, such as Australia in this context, must ensure the aircraft's ongoing compliance with safety standards. CASA, as the national airworthiness authority, must evaluate and implement ADs issued by other states, such as the European Aviation Safety Authority, to maintain safety standards in line with international obligations. Exclusions from public consultation and Regulatory Impact Statements apply to ADs, as they are directly tied to international obligations and are not subject to the usual legislative scrutiny.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework under which airworthiness directives (ADs) are issued. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations for 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 particular types of aircraft or aeronautical products. An AD is considered a legislative instrument under section 46A of the Acts Interpretation Act 1901, and is subject to disallowance under section 6 of the Legislative Instruments Act 2003. This means that ADs are legally binding instruments that mandate compliance with airworthiness standards.
The obligations placed on parties by these regulations are significant. The State of Design, which is the country where an aircraft type is designed, has the primary responsibility for ensuring the continuing airworthiness of that aircraft type, as per Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to States of Registry, which are responsible for individual aircraft's airworthiness. For Australia, CASA, acting as the national airworthiness authority, must evaluate any ADs issued by a State of Design, such as the European Aviation Safety Authority (EASA), and, if necessary, issue a corresponding Australian AD. This ensures that Australian-registered aircraft comply with international airworthiness standards.
Failure to comply with ADs can result in serious consequences. While the specific offences and penalties are not detailed in the provided text, ADs are legally binding, and non-compliance can result in regulatory action, including enforcement measures by CASA. Such actions could involve grounding of non-compliant aircraft, fines, or other penalties that align with aviation safety regulations. The seriousness of these consequences underscores the importance of adhering to ADs to maintain safety standards in aviation.
The issuance of ADs, such as AD/A330/80 for the Airbus A330 model aircraft, is a process driven by international obligations and safety considerations. Given that ADs often respond to findings by the State of Design and are issued under international conventions, there is typically no requirement for public consultation or a Regulatory Impact Statement. Instead, the process is streamlined to ensure timely and effective safety measures. The AD in question was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with the legislative provisions, ensuring a structured approach to compliance and enforcement.
