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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 2004-25-06 affecting Boeing 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-200F and 747-300 series aircraft, together with Model 747SP and 747SR series aircraft. The United States is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/B747/320, which will become effective on 17 February 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 Acting Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted by the Australian Parliament to regulate civil aviation within Australia, focusing on ensuring the safety and efficiency of air navigation. It establishes the legislative framework within which the Civil Aviation Safety Authority (CASA) operates, including the issuance of regulations and directives that maintain safety standards. A notable feature of the Act is its flexibility, allowing the Governor-General to make regulations under section 98 to address safety concerns in air navigation. The Act also aligns with international standards set by the International Civil Aviation Organization (ICAO) and mandates that Australia's national airworthiness authority, CASA, must respond appropriately to airworthiness directives issued by the State of Design, ensuring the continuing airworthiness of aircraft registered in Australia. This regulatory approach reflects a commitment to harmonising national aviation safety standards with international obligations, thereby promoting a consistent and reliable global aviation safety framework.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Regulations 1998, governs various aspects of aviation safety and airworthiness in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products, ensuring the continuing airworthiness of these aircraft. The Act applies to all entities involved in the design, manufacture, and operation of aircraft within Australia, encompassing both domestic and international operations that fall under Australian jurisdiction. The geographic reach of this legislation is national, extending to all aircraft registered in Australia, as well as to those foreign-registered aircraft that operate within Australian airspace. The Act mandates that the State of Registry, in this case CASA, must ensure compliance with airworthiness directives issued by the State of Design, such as the United States Federal Aviation Administration (FAA) in the case of Boeing 747 series aircraft. This ensures that all aircraft registered in Australia meet international safety standards. The Act does not require public consultation for ADs issued in response to international obligations, as determined by the Office of Regulatory Review, which also found that such ADs do not necessitate a Regulatory Impact Statement. The issuance of these ADs is a direct consequence of Australia's obligations under the Convention on International Civil Aviation and is a means to maintain the safety and airworthiness of aircraft operating within Australian jurisdiction.
Key Provisions
The Civil Aviation Act 1988, as amended by the Civil Aviation Regulations 1998, establishes the framework for ensuring the safety of air navigation in Australia. Section 98 of the Act allows the Governor-General to make regulations necessary for the safety of air navigation, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, which means it can be reviewed and potentially disallowed by Parliament.
Under the obligations set forth by the Act, CASA must assess any ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs to ensure the continuing airworthiness of aircraft registered in Australia. The State of Design, in this case the United States for the Boeing 747 series aircraft, has the primary responsibility for the continuing airworthiness of aircraft types, and must provide necessary information to the State of Registry. The State of Registry, represented by CASA in Australia, must then develop or adopt requirements to ensure that the aircraft remain airworthy.
Failing to comply with the ADs issued by CASA can lead to significant consequences. The Act does not explicitly detail penalties for non-compliance with ADs, but non-compliance generally results in the aircraft being deemed unairworthy, which could lead to grounding of the aircraft and potential enforcement actions by CASA. The seriousness of non-compliance is underscored by the safety implications, as ADs are typically issued in response to identified safety issues. Additionally, the legal framework surrounding ADs ensures that any breach is taken seriously, given the critical nature of maintaining airworthiness standards.
Given the global nature of aviation and the obligations under the Convention on International Civil Aviation, ADs such as AD 2004-25-06 issued by the United States Federal Aviation Administration (FAA) are automatically considered by CASA. This AD, affecting various Boeing 747 series aircraft, was assessed by CASA and resulted in the issuance of Australian AD/B747/320. Because these ADs are in response to international obligations and directly tied to the ADs issued by the State of Design, they do not require public consultation or a Regulatory Impact Statement. The ADs are issued in accordance with the statutory authority provided by subsection 84A(2) of the Act, ensuring they are legally sound and aligned with international standards.
