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 US FAA has issued AD 2007-02-24 affecting Boeing B747 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B747/355, which will become effective on 15 March 2007.
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, Airframes 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 ensure the safety and efficiency of civil aviation in Australia. One significant regulation made under this Act is the Civil Aviation Safety Regulations 1998, which were designed to maintain the highest safety standards in the aviation industry. The regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft and aeronautical products to ensure that these meet the necessary safety standards. These ADs are legislative instruments that can be issued in response to safety concerns identified by the State of Design or as a requirement under international aviation agreements, such as the Convention on International Civil Aviation. This legislative framework ensures that Australia meets its international obligations while maintaining the safety of its airspace and its aircraft.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides the legal framework within which airworthiness directives (ADs) are issued to ensure the safety of air navigation in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) has the authority to issue ADs for specified types of aircraft or aeronautical products. These directives are essential for maintaining the continuing airworthiness of aircraft, as they mandate specific safety requirements in response to identified safety issues. The authority to issue ADs is rooted in international obligations under the Convention on International Civil Aviation, particularly through Annex 8, which delineates the responsibilities of the State of Design and the State of Registry in ensuring aircraft airworthiness. ADs are typically issued by the State of Design and, in the case of aircraft registered in Australia, CASA must assess and, if necessary, issue corresponding Australian ADs. This process ensures that Australian aviation adheres to international safety standards. The legislative instruments act and the acts interpretation act further underpin the regulatory framework, classifying ADs as disallowable instruments and legislative instruments respectively. Notably, ADs do not require public consultation or a regulatory impact statement, reflecting their technical nature and the international context in which they are issued.
Key Provisions
The Civil Aviation Act 1988 (sections 98 and 84A) empowers the Governor-General to make regulations, including issuing airworthiness directives (ADs), for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. This regulatory framework is designed to ensure that aircraft remain airworthy over time.
The obligations imposed by the Civil Aviation Act and its associated regulations primarily fall on CASA, the national airworthiness authority. CASA is tasked with assessing information from the State of Design, such as the United States Federal Aviation Administration (FAA) in the case of Boeing B747 aircraft, and issuing corresponding Australian ADs. These ADs are legislative instruments, governed by the Legislative Instruments Act 2003 and the Acts Interpretation Act 1901. The State of Registry, in this instance CASA, must ensure that the continuing airworthiness of aircraft registered in Australia is maintained, aligning with the international obligations outlined in Annex 8 to the Convention on International Civil Aviation.
Breaching the requirements set forth by an AD can lead to significant consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties can include imprisonment, reflecting the serious nature of ensuring aviation safety. The specifics of these penalties are detailed in the Civil Aviation Act and related regulations, with maximum penalties varying based on the severity of the breach and the specific provisions of the AD in question.
The process of issuing ADs, particularly those in response to international directives, is streamlined to ensure timely compliance with global safety standards. For example, AD 2007-02-24 issued by the US FAA for Boeing B747 aircraft was assessed by CASA, leading to the issuance of Australian AD/B747/355. This AD, effective from 15 March 2007, was issued without public consultation, as it was deemed necessary under international obligations and in response to an AD from the relevant State of Design. Furthermore, the Office of Regulatory Review has determined that such ADs do not require a Regulatory Impact Statement, facilitating a swift response to safety concerns.
