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 2008-22-12 affecting Boeing B727 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B727/215, which will become effective on 15 January 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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes & Structures in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legal framework for the regulation of civil aviation in Australia, with a primary focus on ensuring the safety and efficiency of air navigation. Under this Act, the Governor-General is empowered to make regulations necessary for the purposes of the Act and for the safety of air navigation. One significant regulation made under the Act is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. The ADs serve as a means to ensure the continuing airworthiness of aircraft, in line with Australia's obligations under the Convention on International Civil Aviation and the specific requirements of the relevant State of Design.
The ADs are issued by CASA, as Australia's national airworthiness authority, in response to directives issued by the State of Design or as a result of CASA's own assessments. The issuance of ADs is a critical mechanism for maintaining the safety standards of aircraft registered in Australia, and it does not require consultation with the Australian public or the preparation of a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs are considered legislative instruments and are subject to disallowance under the Acts Interpretation Act 1901. The ADs are issued in accordance with the legislative framework provided by the Civil Aviation Act 1988, ensuring that Australia meets its international obligations and maintains high safety standards for civil aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically regulation 39.001, grants the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. These ADs, which are legislative instruments as per the Legislative Instruments Act 2003, are mandated by the Civil Aviation Act 1988 to ensure the safety of air navigation. The application of these directives extends to all aircraft registered in Australia, as the State of Registry holds responsibility for the continuing airworthiness of these aircraft. This includes the enforcement of ADs issued by the State of Design, such as the recent Australian AD/B727/215 issued in response to an AD from the United States Federal Aviation Administration (FAA) concerning Boeing B727 model aircraft. The geographic scope of these regulations is national, covering all aircraft within Australia's jurisdiction. However, these directives do not require consultation with the Australian public or a Regulatory Impact Statement, as they are issued in compliance with international obligations under the Convention on International Civil Aviation and in response to directives from the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 establish the framework under which airworthiness directives (ADs) can be issued to ensure the safety of aircraft. Section 98 of the Act allows the Governor-General to create regulations for the safety of air navigation, and regulation 39.001 of the 1998 Regulations specifically empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. This regulatory process ensures that specific safety concerns or modifications identified for a particular aircraft type can be effectively communicated and enforced.
Under these provisions, CASA has the responsibility to issue ADs that mandate specific safety measures or corrective actions. For example, when the US Federal Aviation Administration (FAA) issued an AD for Boeing B727 model aircraft, CASA assessed this directive and, if necessary, issued a corresponding Australian AD to mandate the same requirements for aircraft registered in Australia. This ensures that aircraft operating in Australia meet internationally recognised safety standards. The ADs are developed in line with the State of Design's obligations under Annex 8 to the Convention on International Civil Aviation, which places responsibility on the State of Design to provide information necessary for continuing airworthiness.
Compliance with ADs is mandatory for aircraft registered in Australia, and the State of Registry is responsible for ensuring the aircraft's continuing airworthiness. This means that aircraft operators must follow the instructions and requirements outlined in any AD issued by CASA. Failure to comply with an AD can lead to serious consequences, including the grounding of the aircraft until the required actions are taken. This strict compliance is essential to maintain the high safety standards required in the aviation industry.
There are significant consequences for breaching the requirements set out in an AD. The Civil Aviation Safety Regulations 1998, along with other aviation-related legislation, provide for various civil and criminal penalties for non-compliance. For example, failure to adhere to an AD can result in fines and imprisonment, with the specific penalties varying depending on the severity of the breach. Such stringent measures underscore the importance of adhering to ADs to ensure the safety and integrity of air navigation.
