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 2008-0139 affecting Diamond Aircraft Industries DA42 model aircraft. EASA acts on behalf of Austria, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DA42/7, which will become effective on 25 September 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 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 comprehensive legal framework for civil aviation in Australia, addressing the need for robust and standardised regulations to ensure the safety and efficiency of air navigation. One of the significant features of this Act is its provision for the creation of regulations that align with international standards, particularly those set by the International Civil Aviation Organization (ICAO). Under section 98 of the Act, the Governor-General has the authority to enact these regulations in the interests of air navigation safety. The Civil Aviation Safety Regulations 1998, made pursuant to this Act, further detail the regulatory mechanisms, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) for specified types of aircraft or aeronautical products. This legislative framework ensures that Australia adheres to international obligations and maintains high safety standards in civil aviation.
The issuance of ADs, such as AD/DA42/7 for the Diamond Aircraft Industries DA42 model, exemplifies the application of these regulations. CASA, acting as Australia's national airworthiness authority, evaluates and adopts ADs issued by the State of Design, such as the European Aviation Safety Authority on behalf of Austria, to maintain the continuing airworthiness of aircraft registered in Australia. This process is conducted in accordance with international conventions and does not typically require public consultation, as determined by the Office of Best Practice Regulation, which has also found that such ADs do not necessitate a Regulatory Impact Statement. The AD is issued under the authority of the Manager, Airframes in the Airworthiness Engineering Branch of CASA, pursuant to subsection 84A(2) of the Act, ensuring that the regulatory measures are implemented effectively and efficiently.
Scope and Application
The Civil Aviation Act 1988, through its associated Civil Aviation Safety Regulations 1998, mandates that the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. These directives apply to specific types of aircraft or aeronautical products and are a legislative instrument under the Acts Interpretation Act 1901 and Legislative Instruments Act 2003. The ADs are integral to maintaining the continuing airworthiness of aircraft as required by Annex 8 of the Convention on International Civil Aviation. The State of Design, such as Austria for the Diamond Aircraft Industries DA42 model, is responsible for issuing ADs, and CASA, as Australia’s national airworthiness authority, must assess and, if appropriate, issue Australian ADs to enforce these requirements. Exemptions from public consultation and Regulatory Impact Statements apply to ADs due to their international obligations and specific regulatory nature. This AD, issued in response to EASA’s AD 2008-0139, was made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in line with the Act’s provisions.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legislative framework for issuing airworthiness directives (ADs). Under section 98 of the Act, the Governor-General has the authority to make regulations necessary for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for certain kinds of aircraft or aeronautical products. These ADs are considered legislative instruments and are subject to disallowance under section 46A of the Acts Interpretation Act 1901, as per subregulation 39.001(5).
The obligations imposed by the Act and the Regulations on CASA and other parties are significant. CASA, as Australia’s national airworthiness authority, has a responsibility to assess any ADs issued by the State of Design and to determine whether these need to be implemented in Australia. This involves ensuring that any continuing airworthiness issues identified by the State of Design are adequately addressed in the Australian context. The State of Registry, in this case CASA, must then develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia, aligning with international standards and obligations under the Convention on International Civil Aviation.
In terms of compliance and enforcement, breaches of ADs can have serious legal consequences. Although the specific offences and penalties are not detailed in the text provided, it is clear that non-compliance with ADs could result in significant regulatory and potentially criminal consequences. These consequences could include fines, imprisonment, or other penalties as prescribed under relevant aviation legislation. The seriousness of these penalties underscores the importance of adhering to ADs to maintain the safety and airworthiness of aircraft.
It is also worth noting that the process of issuing ADs is heavily influenced by international obligations and standards. When a State of Design, such as Austria in the case of the Diamond Aircraft Industries DA42 model, issues an AD, CASA must assess and, if necessary, issue a corresponding Australian AD. This process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD is made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, ensuring that the directive is issued in accordance with the legislative framework provided by the Civil Aviation Act 1988.
