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 Transport Canada has issued AD CF-2002-07 affecting Bombardier DHC-8-400 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/112, which will become effective on 16 March 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, enacted by the Commonwealth Parliament, addresses the regulation of civil aviation in Australia, with a key focus on ensuring the safety of air navigation. This legislative framework provides the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) in accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as legislative instruments to mandate safety measures and are essential for maintaining the continuing airworthiness of aircraft registered in Australia. The Civil Aviation Act 1988 thus facilitates Australia's adherence to international standards set by the Convention on International Civil Aviation, particularly concerning the responsibilities of the State of Design and State of Registry in ensuring aircraft safety. In alignment with these international obligations, CASA issues Australian ADs in response to directives from the relevant State of Design, without the need for public consultation as determined by the Office of Regulatory Review.
Scope and Application
The Civil Aviation Act 1988, through the issuance of airworthiness directives (ADs), applies to the continuing airworthiness of aircraft and aeronautical products in Australia, ensuring compliance with international safety standards. The Act mandates that the Civil Aviation Safety Authority (CASA) can issue ADs to address safety concerns identified by the State of Design or as required by international conventions such as Annex 8 to the Convention on International Civil Aviation. The scope of the Act extends to aircraft registered in Australia and is not limited by geographic boundaries, ensuring alignment with global safety protocols. ADs are legislative instruments and serve as a mechanism for CASA to mandate corrective actions to maintain airworthiness. While the Act broadly applies to all relevant aircraft and aeronautical products, specific ADs are issued in response to identified safety issues and are not subject to public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review. The application of the ADs is governed by the Civil Aviation Safety Regulations 1998, which allow CASA to issue these directives based on assessments of international ADs.
Key Provisions
The key operative sections of this legislation pertain to the issuance and enforcement of airworthiness directives (ADs) under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. Specifically, section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for kinds of aircraft or aeronautical products. An AD is defined as a disallowable instrument under subregulation 39.001(5), making it a legislative instrument under section 6 of the Legislative Instruments Act 2003. These provisions ensure that ADs are legally binding and enforceable within Australia.
The Act imposes several obligations on the parties and entities it governs. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide any necessary information to ensure the continuing airworthiness of a type to the appropriate State of Registry. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. CASA, as Australia’s national airworthiness authority, has the responsibility to assess information from the State of Design and, if appropriate, issue an Australian AD to mandate the requirements of the State of Design. This ensures that all aircraft registered in Australia meet the required safety standards.
Breaching the requirements set out in an AD can lead to serious consequences. Although the specific offences, penalties, or consequences are not detailed in the text provided, it is clear that non-compliance with an AD is likely to be treated as a serious breach of aviation safety regulations. Such breaches could potentially lead to enforcement actions by CASA, including fines, suspension or revocation of airworthiness certificates, and possibly criminal charges for individuals or companies found to be in violation of the ADs. The seriousness of these consequences underscores the importance of adhering to the safety requirements outlined in the ADs.
