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.
Transport Canada has issued AD CF-2009-10 affecting Bell 206 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/176, which will become effective on 13 March 2009.
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& Structures 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 regulate and ensure the safety of civil aviation in Australia. The Act grants the Governor-General the authority to create regulations for air navigation safety. Under section 98 of this Act, the Civil Aviation Safety Regulations 1998 were introduced, empowering the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified aircraft types or aeronautical products. This legislative framework is integral to fulfilling Australia's responsibilities under the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design holds primary responsibility for the continuing airworthiness of aircraft types. Consequently, CASA is obligated to assess and, if necessary, issue Australian ADs that reflect the requirements set by the State of Design, ensuring compliance with international standards and the safety of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia to ensure the safety of air navigation. Under this legislative framework, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specific kinds of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments, subject to disallowance and oversight under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003, respectively. The scope of these directives applies to aircraft registered in Australia and mandates adherence to airworthiness standards established by both the State of Design and the State of Registry, in line with international conventions such as Annex 8 to the Convention on International Civil Aviation. The issuance of ADs is typically a response to safety concerns raised by the State of Design, necessitating CASA’s assessment and potential local adaptation. Given the international obligations and the technical nature of these directives, no public consultation is required, and they do not necessitate a Regulatory Impact Statement. The Manager, Airframes & Structures in the Airworthiness Engineering Group at CASA issues these directives in accordance with the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products (reg. 39.001(5)). These directives are legal instruments that mandate certain actions to maintain the airworthiness of aircraft, and they are recognised under the Legislative Instruments Act 2003 as disallowable instruments (s. 6). This means that they are subject to parliamentary review, which ensures a level of accountability and scrutiny. These directives are typically issued in response to safety concerns or necessary updates to ensure compliance with international standards set by the Convention on International Civil Aviation, specifically under Annex 8. This convention assigns the State of Design, the country where the aircraft was designed, the responsibility for the continuing airworthiness of an aircraft type, and requires them to share necessary information with the State of Registry, which is the country where the aircraft is registered.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA to closely monitor ADs issued by the State of Design. When a State of Design, such as Canada in the case of the Bell 206 model helicopter, issues an AD, CASA must evaluate this information and determine if an equivalent AD is necessary for Australian-registered aircraft. If deemed appropriate, CASA issues an Australian AD to ensure that all aircraft of that type registered in Australia meet the same safety requirements. This process ensures that Australian aviation remains compliant with international safety standards and that all aircraft operating within Australia are subject to rigorous safety oversight.
Failure to comply with the requirements set forth in an AD can result in serious legal and safety consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can lead to civil penalties, including fines, and potentially criminal charges. The severity of these penalties reflects the importance of adhering to airworthiness directives, which are designed to prevent accidents and ensure the safety of all persons on board an aircraft. For example, if an aircraft is found to be operating without the necessary modifications or inspections as required by an AD, the operator could face significant fines and even prosecution, highlighting the critical nature of compliance with these safety regulations.
While the legislative framework does not mandate public consultation for the issuance of ADs, as they are developed in response to international obligations and safety concerns, they are still subject to internal review processes within CASA. This ensures that any AD issued is based on thorough technical evaluation and necessary safety measures. The Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement, which streamlines the process and ensures that safety measures can be implemented promptly without excessive bureaucratic delay. This approach balances the need for rapid response to safety issues with the requirement for due process and accountability in regulatory decision-making.
