CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 2005-07-20 affecting Boeing 737 model aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B737/240, which will become effective on 9 June 2005.
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 Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was designed to regulate the safety and efficiency of civil aviation in Australia, ensuring that all operations adhere to stringent safety standards. The Act empowers the Governor-General to issue regulations for the safety of air navigation, which allows for the establishment of protocols such as the issuing of airworthiness directives (ADs) to address specific safety concerns with aircraft or aeronautical products. The Civil Aviation Safety Regulations 1998 further detail the mechanisms by which these directives can be issued, with ADs serving as legislative instruments that align with international standards under the Convention on International Civil Aviation. This legislative framework ensures that Australia’s national airworthiness authority, CASA, can respond swiftly to safety issues identified by the State of Design, thereby maintaining the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, provide the legislative framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General can issue regulations necessary for the Act, and 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. These directives, which are considered legislative instruments, are issued to maintain and ensure the continuing airworthiness of aircraft, in line with international obligations under the Convention on International Civil Aviation. The State of Design has the primary responsibility for the airworthiness of an aircraft type, and the State of Registry must implement and enforce the necessary requirements. When a foreign State of Design issues an AD, CASA evaluates the information and, if appropriate, issues an Australian AD. For instance, CASA has issued AD/B737/240 in response to the United States FAA's AD 2005-07-20 for Boeing 737 models, reflecting Australia's commitment to international safety standards and effective on 9 June 2005.
Key Provisions
The Civil Aviation Act 1988 and its associated regulations, specifically under section 98 and regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that aim to ensure the continuing airworthiness of aircraft, and they are issued in accordance with international standards set out in Annex 8 to the Convention on International Civil Aviation. The State of Design, in this case the United States for Boeing 737 model aircraft, has a responsibility to provide necessary information to ensure airworthiness, and CASA, as Australia’s national airworthiness authority, must then assess this information and issue corresponding Australian ADs if deemed necessary.
Entities governed by these provisions, primarily CASA and the States of Design and Registry, have distinct responsibilities under the Civil Aviation Regulations 1998. CASA is tasked with assessing ADs issued by the State of Design and, where appropriate, issuing Australian ADs to mandate compliance with the original directives. States of Design are required to provide continuing airworthiness information, while States of Registry must develop or adopt requirements to ensure the ongoing airworthiness of aircraft within their jurisdiction. These obligations necessitate a collaborative approach to maintaining international standards of air safety and ensuring that aircraft remain airworthy.
Failure to comply with the requirements set out in an AD can result in serious consequences. The Civil Aviation Act 1988 and associated regulations establish penalties for non-compliance, which can include both civil and criminal sanctions. For instance, individuals or corporations that fail to adhere to the mandated airworthiness directives may face fines, imprisonment, or both, depending on the severity and nature of the breach. The specific penalties are not detailed in the text provided but generally reflect the seriousness of endangering public safety through non-compliance with airworthiness directives.
