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 2006-06-03 affecting Cessna 500, 501, 550, S550, 551 and 560 aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CESSNA 550/26 and AD/CESSNA 560/8, which will become effective on 20 April 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 comprehensive legal framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations necessary for the safety of air navigation, delegating specific regulatory responsibilities to the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, made under section 98 of the Civil Aviation Act 1988, further elaborate on the regulatory mechanisms, including the issuance of airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft types. This legislative framework responds to international obligations under the Convention on International Civil Aviation, which places the responsibility for the continuing airworthiness of aircraft types on the State of Design, with States of Registry required to implement and enforce these directives. The issuance of ADs is critical in ensuring that aircraft operating in Australia meet international safety standards, thereby facilitating safe and efficient air navigation within and beyond Australian airspace.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, provide for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under section 98 of the Civil Aviation Act 1988, aimed at ensuring the safety of air navigation. Specifically, regulation 39.001 empowers CASA to issue ADs concerning types of aircraft or aeronautical products, with these directives being classified as disallowable instruments under the Acts Interpretation Act 1901 and legislative instruments under the Legislative Instruments Act 2003. The application of these directives extends to all aircraft types registered in Australia, aligning with international standards set forth by the Convention on International Civil Aviation, particularly Annex 8, which mandates that the State of Design is responsible for the continuing airworthiness of an aircraft type. Consequently, when an AD is issued by a State of Design, such as the United States Federal Aviation Administration (FAA) for specific Cessna aircraft models, CASA is required to evaluate and, if necessary, issue corresponding Australian ADs to maintain airworthiness standards. This process ensures that Australian-registered aircraft meet the necessary safety requirements as determined by the State of Design and international conventions.
Key Provisions
The Civil Aviation Act 1988, and specifically section 98, grants the Governor-General the authority to make regulations for the safety of air navigation, which includes the issuance of airworthiness directives (ADs) as outlined in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments and serve to mandate requirements for the continuing airworthiness of aircraft. The State of Design, in this case the United States, is responsible for ensuring the continuing airworthiness of aircraft types, and under Annex 8 to the Convention on International Civil Aviation, they must provide necessary information to the States of Registry, which includes Australia. CASA, as the national airworthiness authority, must then assess this information and, if necessary, issue corresponding ADs to comply with international obligations and ensure safety.
In practical terms, the obligations imposed by the Civil Aviation Safety Regulations 1998 and the Convention on International Civil Aviation require CASA to rigorously evaluate any ADs issued by the State of Design, such as the United States FAA's AD 2006-06-03 for certain Cessna aircraft. Once an assessment is complete, CASA may issue its own ADs, as seen with AD/CESSNA 550/26 and AD/CESSNA 560/8, which will take effect from 20 April 2006. These ADs mandate specific actions to maintain airworthiness, ensuring that aircraft registered in Australia meet the safety standards set by international and domestic regulations.
Any breaches of the ADs issued by CASA can result in severe consequences. Failure to comply with the requirements set out in these ADs can lead to aircraft being grounded, which can disrupt operations and potentially result in criminal or civil penalties. The maximum penalties for non-compliance can include fines, imprisonment, or both, depending on the severity of the breach and the discretion of the court. These penalties are designed to enforce compliance and maintain the high safety standards required in civil aviation.
It is worth noting that ADs are not subject to the same public consultation processes as other legislative instruments, given their urgent nature and the necessity to align with international aviation safety standards. Additionally, these ADs do not require a Regulatory Impact Statement, as determined by the Office of Regulatory Review, streamlining the process of issuing and enforcing these safety mandates. This ensures that any necessary actions to address safety concerns can be implemented swiftly and effectively, without unnecessary bureaucratic delays.
