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 United States FAA has issued AD 2006-04-10 affecting Cessna Model 550 and S550 aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CESSNA 550/25, which will become effective on 11 May 2006.
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, New Technologies and Systems, in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety of air navigation. The Act empowers the Governor-General to make regulations that support the overarching objectives of air safety, as per section 98. In this context, the Civil Aviation Safety Regulations 1998 were introduced to further specify the requirements and processes for maintaining the airworthiness of aircraft. Regulation 39.001 of these regulations allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives, as outlined in subregulation 39.001(5), are classified as disallowable instruments under the Acts Interpretation Act 1901 and thus are legislative instruments themselves. The issuance of these ADs is mandated to align with international standards, particularly under Annex 8 of the Convention on International Civil Aviation, which designates the State of Design with the responsibility for ensuring the continuing airworthiness of aircraft types and requiring them to provide necessary information to States of Registry.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, governs the issuance of airworthiness directives (ADs) to ensure 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 specific types of aircraft or aeronautical products. These ADs are legislative instruments that fall under the purview of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are intended to address continuing airworthiness, a responsibility that lies with the State of Design under Annex 8 of the Convention on International Civil Aviation. The State of Registry, in this case CASA as Australia’s national airworthiness authority, must assess ADs issued by the State of Design and, if deemed necessary, issue corresponding Australian ADs to enforce the required safety measures. This process ensures compliance with international standards and facilitates effective communication of safety directives across jurisdictions.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 outline the framework for issuing airworthiness directives (ADs) to ensure the safety of air navigation. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations in the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Importantly, subregulation 39.001(5) specifies that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are considered legislative instruments under the Legislative Instruments Act 2003.
The obligations imposed by the Act and Regulations on the parties involved are significant. The State of Design, in this case, the United States for the Cessna Model 550 and S550 aircraft, has the primary responsibility for the continuing airworthiness of the aircraft type. It must provide necessary information to ensure the airworthiness of the aircraft type to the appropriate States of Registry, which in this case is Australia. CASA, as Australia's national airworthiness authority, is obligated to assess the ADs issued by the State of Design and, if necessary, issue Australian ADs to mandate the requirements for aircraft registered in Australia.
Failure to comply with the ADs can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an airworthiness directive can be considered an offence. Such offences may carry significant penalties. While the specific penalties are not detailed in the provided text, generally, penalties for breaches of civil aviation regulations can include substantial fines and, in severe cases, imprisonment. The exact penalties would be determined based on the nature and severity of the breach, as well as the specific provisions of the Civil Aviation Act 1988 and related regulations. The issuance of ADs under these legislative provisions is crucial to maintaining the safety standards required by international conventions and domestic law.
