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 2008-06-24 affecting Boeing 737 series aircraft. The United States is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/B737/322, 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, Systems and New Technologies 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 Parliament of Australia, was introduced to ensure the safety of air navigation by providing a legislative framework for regulating civil aviation activities within Australia. This Act empowers the Governor-General to create regulations that maintain the safety standards of air navigation, thus establishing a foundation for the regulatory oversight exercised by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, which complement the Act, further detail the procedures and requirements necessary for maintaining airworthiness, including the issuance of airworthiness directives (ADs) as mandated by regulation 39.001. These ADs, which are legislative instruments subject to disallowance under the Acts Interpretation Act 1901, are crucial for ensuring that aircraft remain in a safe condition for operation.
The process of issuing ADs in Australia is closely aligned with international standards, particularly those set by the International Civil Aviation Organization (ICAO) under Annex 8 to the Convention on International Civil Aviation. This convention delineates the responsibilities of States of Design and States of Registry in maintaining the continuing airworthiness of aircraft. In Australia, CASA, as the national airworthiness authority, assumes the responsibility of assessing and, if necessary, issuing ADs to address safety issues identified by the State of Design. This mechanism ensures that Australian aircraft comply with international safety standards and are subject to appropriate regulatory oversight.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide the legislative framework for the regulation of civil aviation in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products, which are legislative instruments as per section 6 of the Legislative Instruments Act 2003. ADs are essential for ensuring the continuing airworthiness of aircraft and are issued by CASA in response to international obligations under the Convention on International Civil Aviation. The State of Design for a particular aircraft type is responsible for issuing ADs, and CASA, as the State of Registry for Australian registered aircraft, must assess and, if necessary, issue corresponding Australian ADs to enforce the requirements of the State of Design. This process ensures compliance with international standards and the safety of air navigation within Australia.
Key Provisions
The Civil Aviation Act 1988, through section 98, empowers the Governor-General to enact regulations in the interest of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. Subregulation 39.001(5) specifies that these ADs are disallowable instruments, making them legislative instruments under section 6 of the Legislative Instruments Act 2003. This means ADs are formal rules that have legal standing.
The obligations imposed by these provisions include the State of Design's responsibility, under Annex 8 of the Convention on International Civil Aviation, to ensure the continuing airworthiness of aircraft types and to provide necessary information to States of Registry. The State of Registry, in turn, is responsible for the continuing airworthiness of individual aircraft and must develop or adopt requirements to maintain this airworthiness. When a State of Design issues an AD, CASA, as Australia's national airworthiness authority, must evaluate the information and, if necessary, issue an Australian AD to enforce the requirements set by the State of Design.
In the case of AD 2008-06-24 issued by the United States Federal Aviation Administration (FAA) for Boeing 737 series aircraft, CASA has assessed this AD and issued Australian AD/B737/322, which will take effect on 5 June 2008. Since this AD is issued in response to international obligations and directly related to an AD from the relevant State of Design, no public consultation has occurred. Furthermore, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. This AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Any breaches of ADs may result in severe consequences. Non-compliance with ADs can lead to enforcement actions under section 14ZA of the Civil Aviation Act 1988, which empowers CASA to take measures such as grounding aircraft, imposing fines, or taking other regulatory actions. The maximum penalties for non-compliance can include substantial fines and potential imprisonment, depending on the severity and circumstances of the breach. These provisions ensure that all stakeholders adhere to safety standards and maintain the integrity of air navigation.
