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 European Aviation Safety Authority (EASA) has issued AD 2006-0371-E affecting Agusta AB206 model helicopters. EASA acts on behalf of Italy, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BELL 206/165, which will become effective on 18 December 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 ensure the safety of air navigation and to provide a framework for the regulation of civil aviation in Australia. One of the key mechanisms through which the Act achieves this is by enabling the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives are legislative instruments made by the Civil Aviation Safety Authority (CASA) and are critical in maintaining the continuing airworthiness of aircraft. The Act empowers the Governor-General to make regulations for the safety of air navigation, and in this context, ADs serve as a means to address identified safety issues for specific types of aircraft or aeronautical products. The Civil Aviation Act 1988 and the subsequent regulations are designed to align with international standards, particularly under Annex 8 to the Convention on International Civil Aviation, ensuring that Australia meets its obligations as a State of Registry while also respecting the responsibilities of the State of Design.
Scope and Application
The Civil Aviation (Airworthiness Directives) Regulations 1998 apply to all persons and entities involved in the operation, maintenance, and certification of aircraft within Australia, as well as to any aeronautical products used in Australian aviation. These regulations are designed to ensure the continuing airworthiness of aircraft by mandating compliance with specific safety directives. The geographic reach of these regulations is national, extending across the Commonwealth of Australia, and they are aligned with international standards set by the International Civil Aviation Organization (ICAO). The regulations allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives that may apply to certain types of aircraft or aeronautical products, and these directives are legally binding under Australian law. However, the regulations do not apply to aircraft and aeronautical products that are exempt under specific conditions, such as those used solely for non-commercial purposes or those not registered in Australia. Subordinate instruments may extend or restrict the application of these regulations, but the primary focus remains on maintaining high safety standards in the aviation industry.
Key Provisions
The Civil Aviation Safety Regulations 1998, under regulation 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. This regulatory authority is rooted in section 98 of the Civil Aviation Act 1988, which allows the Governor-General to make regulations in the interest of air navigation safety. Importantly, under subregulation 39.001(5), ADs are recognised as disallowable instruments as per section 46A of the Acts Interpretation Act 1901, thus classifying them as legislative instruments under section 6 of the Legislative Instruments Act 2003.
Compliance with international standards is a cornerstone of these regulations. As per Annex 8 to the Convention on International Civil Aviation, the State of Design holds overarching responsibility for the continuing airworthiness of an aircraft type, which includes providing necessary information to ensure airworthiness to relevant States of Registry. In the context of Australian aviation, CASA, acting as the national airworthiness authority, must evaluate the information provided by the State of Design and, if deemed appropriate, issue an Australian AD to enforce the requirements of the originating State. This ensures that Australian aircraft meet international safety standards.
The obligations imposed by these regulations on parties and entities are stringent and focused on maintaining safety standards. CASA, as the regulatory body, is required to thoroughly assess ADs issued by the State of Design and determine their applicability to aircraft within Australia's jurisdiction. When an AD is issued by a foreign entity like the European Aviation Safety Authority (EASA), CASA must evaluate the directive and, if necessary, issue a corresponding Australian AD. This process underscores the commitment to international cooperation in aviation safety.
Non-compliance with ADs can lead to significant legal consequences. The Civil Aviation Act 1988 and associated regulations impose strict penalties for breaches, which may include both civil and criminal sanctions. The specific penalties for non-compliance can vary depending on the severity and nature of the breach, but they are designed to ensure that airworthiness directives are strictly adhered to. This reinforces the importance of maintaining high safety standards in the aviation industry.
