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 European Aviation Safety Authority (EASA) has issued AD 2008-0069 affecting SAAB 340 model aircraft. EASA acts on behalf of Sweden, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/SF340/106, which will become effective on 5 June 2008.
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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to ensure the safety of air navigation and the regulation of civil aviation in Australia. Under this Act, the Civil Aviation Safety Regulations 1998 were established to govern various aspects of aviation safety, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments that mandate the continuing airworthiness of aircraft, aligning with international standards set forth by the International Civil Aviation Organization (ICAO). The Act facilitates Australia's adherence to its obligations under the Convention on International Civil Aviation by allowing CASA to issue ADs in response to directives from the State of Design, such as the European Aviation Safety Authority for certain aircraft types. This mechanism ensures that Australian aircraft meet necessary safety standards as required by international agreements.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes a comprehensive framework for ensuring the safety of air navigation within Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs, which are legislative instruments, mandate compliance with safety standards and are crucial for maintaining the continuing airworthiness of aircraft registered in Australia. The authority to issue these directives arises from the overarching responsibility of the State of Design to provide necessary information for ensuring aircraft airworthiness, as outlined in Annex 8 of the Convention on International Civil Aviation. When the European Aviation Safety Authority (EASA), acting on behalf of Sweden as the State of Design for SAAB 340 model aircraft, issues an AD, CASA evaluates this information and, if necessary, issues a corresponding Australian AD to enforce the required safety measures. Given the international nature of these directives and their alignment with Australia's obligations under international civil aviation conventions, no public consultation is required, and no Regulatory Impact Statement is needed, as determined by the Office of Best Practice Regulation.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to establish regulations in the interest of air navigation safety. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specified types of aircraft or aeronautical products. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and qualifies as a legislative instrument pursuant to section 6 of the Legislative Instruments Act 2003. These directives are pivotal in maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation.
Under this international convention, the State of Design holds primary responsibility for the continuing airworthiness of an aircraft type, necessitating the provision of necessary information to States of Registry. These states must subsequently develop or adopt measures to ensure the ongoing airworthiness of aircraft on their registry. For instance, when the State of Design, Sweden, via the European Aviation Safety Authority (EASA), issues AD 2008-0069 for the SAAB 340 model, CASA, as Australia’s national airworthiness authority, is obligated to assess the information and, if appropriate, issue a corresponding Australian AD, such as AD/SF340/106, to enforce the required measures.
Entities governed by the Civil Aviation Act 1988 and its regulations, including CASA and State of Registry authorities, bear significant responsibilities to ensure aircraft airworthiness. CASA must meticulously evaluate foreign ADs and issue corresponding Australian directives when necessary. States of Registry must implement these directives to maintain the airworthiness of aircraft registered within their jurisdiction. This includes compliance with the technical and procedural requirements outlined in any issued ADs.
Failure to comply with airworthiness directives can lead to serious consequences. Although specific penalties are not detailed in the provided text, breaches of regulations under the Civil Aviation Act 1988 can result in both civil and criminal penalties. Civil penalties may include fines, while criminal penalties could encompass imprisonment, depending on the severity of the breach. The gravity of non-compliance is underscored by the potential for safety hazards, which can lead to accidents and loss of life. Therefore, adherence to ADs is not only a regulatory requirement but a critical safety imperative.
