CIVIL AVIATION ACT 1988
CIVIL AVIATION 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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 United States FAA has issued AD 2003-14-03 Amendment 39-13222 affecting Textron Lycoming Engines. United States of America is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/LYC/110, which will become effective on 17 February 2005.
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 Section Head – Systems Section, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation safety and efficiency within Australia, addressing the need for a comprehensive legal framework governing the safety, efficiency, and orderly development of civil aviation in the country. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation, as exemplified by the Civil Aviation Regulations 1998. These regulations, including the issuance of airworthiness directives under section 39.001, aim to ensure that aircraft and aeronautical products maintain their airworthiness. The policy objective is to uphold international safety standards, as articulated in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds overall responsibility for the continuing airworthiness of aircraft types. In response to an airworthiness directive issued by the United States Federal Aviation Administration, CASA has issued its own directive to mandate the necessary requirements for aircraft registered in Australia, demonstrating the practical implementation of these legislative provisions.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide the legislative framework for ensuring the safety of air navigation in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001. These ADs are essential instruments designed to maintain the continuing airworthiness of aircraft, aligning with Australia's obligations under the Convention on International Civil Aviation, particularly Annex 8. The ADs are issued in response to assessments of directives from the State of Design, which holds the primary responsibility for the airworthiness of a particular aircraft type, and in accordance with the requirements set by the State of Registry, which, in the case of Australia, is CASA. Notably, ADs such as the one issued for Textron Lycoming Engines by CASA do not require public consultation or a Regulatory Impact Statement, as they are issued in direct response to international obligations and directives from the State of Design. The ADs serve to mandate specific maintenance, repair, or operational requirements to ensure the safety and compliance of aircraft registered in Australia with international standards.
Key Provisions
The Civil Aviation Act 1988, and the Civil Aviation Safety Regulations 1998, establish a framework for ensuring the safety of air navigation, with particular emphasis on the airworthiness of aircraft. Under section 98 of the Act, the Governor-General has the authority to make regulations that align with the Act's objectives and safety requirements, while regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are formal instructions designed to ensure the ongoing safety and airworthiness of the aircraft, and they fall under the category of disallowable instruments as per section 46A of the Acts Interpretation Act 1901.
The obligations imposed by these provisions require CASA to act upon ADs issued by the State of Design, which is responsible for the continuing airworthiness of an aircraft type under Annex 8 to the Convention on International Civil Aviation. For instance, when the United States Federal Aviation Administration (FAA) issues an AD for Textron Lycoming Engines, CASA must assess the information and, if deemed necessary, issue a corresponding Australian AD to enforce the requirements. This obligation underscores the importance of international cooperation in maintaining aviation safety standards and highlights the critical role of the State of Registry, in this case Australia, in ensuring that individual aircraft meet the necessary safety criteria.
Failure to comply with the ADs or to issue appropriate directives when necessary can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can result in significant civil or criminal penalties. For example, if an aircraft operator fails to adhere to an AD, they could face fines or even imprisonment, reflecting the serious nature of these regulations in maintaining public safety. While the specific penalties are not detailed in the provided text, it is clear that the law imposes stringent obligations and consequences to ensure that all parties adhere to the highest safety standards.
