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 2007-0219-E affecting Eurocopter EC 130 B4 model helicopters. EASA acts on behalf of France, the State of Design for this type. CASA has assessed this AD and has issued Australian AD/ECUREUIL/128, which will become effective on 28 August 2007.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, serves to ensure the safety and efficiency of civil aviation within Australia, and it provides a framework for regulating the aviation industry. The Act empowers the Governor-General to make regulations, including the issuance of airworthiness directives (ADs) to maintain the safety of air navigation. In accordance with the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is authorised to issue these directives for specific types of aircraft or aeronautical products, ensuring compliance with international standards. The objective of these regulations is to uphold the continuing airworthiness of aircraft and to respond appropriately to directives issued by the State of Design, as stipulated in Annex 8 of the Convention on International Civil Aviation. The issuance of an Australian AD, such as AD/ECUREUIL/128 in response to EASA's AD 2007-0219-E, is mandated by Australia's international obligations and is managed by CASA to maintain safety standards without the need for public consultation or a Regulatory Impact Statement.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for the regulation of airworthiness in Australia. Under this legislative structure, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as outlined in regulation 39.001 of the Civil Aviation Safety Regulations. These ADs are legislative instruments that aim to ensure the continuing airworthiness of aircraft and are essential tools in maintaining safety standards in line with international obligations under the Convention on International Civil Aviation. The application of these ADs is governed by both the Civil Aviation Act 1988 and the Acts Interpretation Act 1901, which outline the legislative processes and requirements for such directives. The ADs issued by CASA apply to aircraft registered in Australia and must be implemented by aircraft operators to comply with national and international safety standards. The issuance of these directives is typically in response to actions by the State of Design or other contracting states, and while they do not require public consultation or a Regulatory Impact Statement, they are crucial for ensuring the safety and airworthiness of aircraft operating within Australia.
Key Provisions
The key provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 that relate to the issuance of airworthiness directives (ADs) are contained in section 98 of the Act (which empowers the Governor-General to make regulations for air navigation safety) and regulation 39.001 of the Regulations (which allows the Civil Aviation Safety Authority, or CASA, to issue ADs for types of aircraft or aeronautical products). According to subregulation 39.001(5), ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus legislative instruments as per section 6 of the Legislative Instruments Act 2003. The continuing airworthiness of an aircraft type falls under the purview of the State of Design, which must furnish necessary information to States of Registry as per Annex 8 of the Convention on International Civil Aviation. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft.
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose specific obligations on CASA, as Australia’s national airworthiness authority. When an AD is issued by the State of Design, CASA must evaluate the information and, if deemed necessary, issue an Australian AD to enforce the requirements specified by the State of Design. This obligation is critical in maintaining compliance with international aviation standards and ensuring the safety of aircraft registered in Australia. Furthermore, CASA must act on ADs issued by international authorities like the European Aviation Safety Agency (EASA) when those ADs pertain to aircraft types registered in Australia.
Failure to comply with the requirements of an AD can lead to significant legal consequences. The Act does not explicitly detail specific offences, penalties, or civil/criminal consequences for non-compliance with ADs, but such non-compliance can result in severe repercussions. Non-compliance with airworthiness directives can lead to the grounding of aircraft, which can cause significant financial and operational disruptions. Furthermore, in extreme cases, non-compliance could result in civil aviation offences under other parts of the Civil Aviation Act 1988, which might carry fines or imprisonment. The exact penalties would depend on the specific breach and the provisions of other relevant laws.
