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.
Transport Canada has issued AD CF-98-23 affecting Bell 430 model helicopters. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 430/7, which will become effective on 26 October 2006.
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 Manager, Airframes in the Manufacturing, Certification and New Technologies Office, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to establish a legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. This Act empowers the Governor-General to make regulations, including the issuance of airworthiness directives (ADs), under section 98 to maintain the safety of air navigation. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, enabling the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. The policy objective of these regulations is to ensure that all aircraft within Australia's jurisdiction maintain their airworthiness in accordance with international standards, thereby safeguarding public safety and harmonising with global aviation practices. The issuing of ADs, as legislative instruments, is integral to fulfilling Australia’s obligations under the Convention on International Civil Aviation, particularly concerning the continuing airworthiness of aircraft types designed in other countries.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain kinds of aircraft or aeronautical products, thus ensuring compliance with the overarching aims of the Civil Aviation Act 1988. These ADs serve as legislative instruments, enforceable within the Commonwealth jurisdiction, and are designed to maintain the continuing airworthiness of aircraft registered within Australia. The ADs are mandated by international obligations under the Convention on International Civil Aviation, particularly through Annex 8, which stipulates that the State of Design holds primary responsibility for the airworthiness of an aircraft type, and must communicate necessary information to the States of Registry to ensure safety standards are upheld. CASA, as Australia’s national airworthiness authority, evaluates this information and, if deemed necessary, issues corresponding Australian ADs to enforce these safety measures. The issuance of such directives does not typically require public consultation as it is a response to international obligations and directives issued by the State of Design.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, allows the Governor-General to enact regulations for the purposes of the Act, focusing on ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 further authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. An AD, as outlined in subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998, is a disallowable instrument according to section 46A of the Acts Interpretation Act 1901 and is classified as a legislative instrument under section 6 of the Legislative Instruments Act 2003. These ADs are integral to maintaining the continuing airworthiness of aircraft types, a responsibility that rests with the State of Design under Annex 8 to the Convention on International Civil Aviation. The State of Registry, which is responsible for the individual aircraft's airworthiness, must also develop or adopt requirements to ensure the ongoing airworthiness of aircraft.
The obligations imposed by these provisions require CASA to assess any ADs issued by the State of Design for aircraft types registered in Australia and, if deemed necessary, to issue corresponding Australian ADs. For instance, Transport Canada's AD CF-98-23, which pertains to Bell 430 model helicopters, has been evaluated by CASA, leading to the issuance of Australian AD/BELL 430/7. This Australian AD is set to become effective on 26 October 2006. Given that this AD is issued in response to Australia's obligations under the Convention on International Civil Aviation and is a direct result of an AD raised by the relevant State of Design, no public consultation has been undertaken. Moreover, the Office of Regulatory Review has concluded that ADs do not require a Regulatory Impact Statement.
Under these regulations, the primary consequence of breaching an airworthiness directive is the potential grounding of the affected aircraft, as ADs are legally binding and their non-compliance can result in severe safety hazards. While the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 do not explicitly detail the specific penalties for non-compliance with ADs, the overarching principle is that failure to adhere to these directives can result in civil or criminal liability. In particular, operators and owners who do not comply with ADs could face enforcement actions from CASA, which might include fines, suspension, or revocation of air operator certificates, or other regulatory sanctions. These measures underscore the critical importance of adhering to ADs to maintain the highest standards of aviation safety.
