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 2009-25R1 affecting Bombardier DHC-8 400 series aeroplanes. Canada is the State of Design for these aeroplanes. CASA has assessed this AD and has issued Australian AD/DHC-8/151, which will become effective on 24 September 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to address the need for a robust regulatory framework to ensure the safety and efficiency of civil aviation in Australia. This legislation empowers the Governor-General to create regulations that promote the safety of air navigation. One significant aspect of this act is the authority granted to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) as stipulated under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are instrumental in maintaining the continuing airworthiness of aircraft, aligning with international standards set forth by the International Civil Aviation Organization (ICAO). The ADs are legislative instruments that mandate specific safety requirements and are issued in response to safety concerns identified by the State of Design or in compliance with international obligations. This legislative approach ensures that Australian civil aviation maintains high safety standards, consistent with global best practices.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and oversight under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003 respectively. They are issued in accordance with Annex 8 to the Convention on International Civil Aviation, which delineates the responsibilities of the State of Design and the State of Registry concerning the continuing airworthiness of aircraft. In Australia, CASA, as the national airworthiness authority, must assess ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs. For instance, in response to Transport Canada's AD 2009-25R1 concerning Bombardier DHC-8 400 series aeroplanes, CASA issued Australian AD/DHC-8/151. This process reflects Australia's international obligations and does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Regulatory Review. The AD is made by the Manager, Future Technology and Regulatory Trends, within CASA’s Standards Development and Future Technology Division, pursuant to subsection 84A(2) of the Civil Aviation Act 1988.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations that serve the safety interests of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework ensures that ADs, which are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, are formally recognised as legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003. This formal recognition underscores the importance of ADs in maintaining airworthiness standards.
The obligations placed on parties under this legislation are significant. The State of Design, such as Canada in the case of the Bombardier DHC-8 400 series aeroplanes, has a primary responsibility to provide information necessary for ensuring the continuing airworthiness of aircraft types, in line with Annex 8 of the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, must rigorously assess the information provided by the State of Design and, if necessary, issue a corresponding Australian AD to enforce the required safety measures. The State of Registry, which in this case is Australia, is also responsible for ensuring the continuing airworthiness of individual aircraft registered within its jurisdiction. This dual responsibility ensures that both the aircraft type and individual aircraft meet stringent safety standards.
Breaching the requirements set out in the ADs can have serious consequences. While the specific penalties are not detailed in the provided text, it is clear that non-compliance with ADs can lead to safety risks and may result in enforcement actions by CASA. The authority has the power to take civil or criminal action against entities or individuals who fail to comply with ADs, although the exact penalties are not specified in the document. The potential consequences highlight the critical importance of adhering to the directives to maintain safety in air navigation.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a robust framework for issuing and enforcing airworthiness directives. The legislation delineates clear responsibilities for the State of Design and the State of Registry, while CASA plays a pivotal role in assessing and implementing these directives within Australia. Non-compliance with these directives can result in significant legal and safety repercussions, underscoring the importance of strict adherence to the established regulations.
