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 2006-0098 affecting Eurocopter SA 341G and SA 342J Gazelle model helicopters. EASA acts on behalf of France, the State of Design for these types. CASA has assessed this AD and has issued Australian AD/GAZELLE/28, Amendment 1, which will become effective on 31 August 2006. This AD cancels and replaces the previous issue.
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 to ensure the safety of air navigation, provides the legislative framework within which the Civil Aviation Safety Regulations 1998 operate. Under this Act, the Governor-General is empowered to issue regulations that serve the interests of aviation safety, including the authority for the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft or aeronautical products. The ADs, as legislative instruments, mandate compliance with safety requirements and reflect Australia’s commitments under international aviation conventions, particularly those outlined in Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 detail the process by which CASA must respond to ADs issued by the State of Design, ensuring that Australian aircraft meet international safety standards. In this context, CASA has issued an AD for Eurocopter SA 341G and SA 342J Gazelle model helicopters, aligning with an AD issued by the European Aviation Safety Authority on behalf of France, the State of Design.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legislative framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These regulations empower CASA to issue ADs for specific types of aircraft or aeronautical products, aligning with international standards set by the International Civil Aviation Organization (ICAO). The ADs serve as a mechanism to ensure the continuing airworthiness of aircraft registered in Australia. The scope of these regulations extends to all aircraft registered within Australia, thereby applying to the State of Registry, which is responsible for the ongoing airworthiness of each individual aircraft. Furthermore, these regulations are applicable in response to directives issued by the State of Design, such as those from the European Aviation Safety Authority (EASA) for aircraft designed within its jurisdiction. The ADs issued by CASA are directly linked to international obligations under the Convention on International Civil Aviation and are not subject to public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review. The issuance of these directives is a statutory responsibility of CASA, carried out under the authority granted by the Act.
Key Provisions
The key provisions of the Civil Aviation Act 1988, as they relate to airworthiness directives, are found in section 98, which empowers the Governor-General to make regulations for the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 authorises the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. It is important to note that these ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and therefore legislative instruments according to section 6 of the Legislative Instruments Act 2003. These directives are crucial for maintaining the continuing airworthiness of aircraft and are issued in accordance with Annex 8 of the Convention on International Civil Aviation.
The obligations imposed by this legislation on parties and entities include the State of Design, which has the overarching responsibility for ensuring the continuing airworthiness of an aircraft type. This responsibility extends to providing necessary information to States of Registry to maintain airworthiness. In Australia, CASA, as the national airworthiness authority, must assess the information provided by the State of Design and, if necessary, issue an Australian AD to enforce the requirements. The State of Registry, which in this context is Australia for the registered aircraft, must also develop or adopt regulations to ensure continuing airworthiness. These obligations ensure that all parties involved in the design, manufacture, and operation of aircraft contribute to the safety and airworthiness of the aircraft in the Australian aviation system.
Failure to comply with the airworthiness directives can result in various civil and criminal consequences. While specific penalties for non-compliance with ADs are not detailed in the provided text, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include provisions for enforcement actions against non-compliance. Such actions may include fines, suspension or revocation of airworthiness certificates, and other regulatory sanctions. It is crucial for all stakeholders, including aircraft manufacturers, operators, and regulatory authorities, to adhere to the ADs to ensure the safety and airworthiness of aircraft, thereby preventing potential accidents and maintaining the integrity of the aviation system.
