CIVIL AVIATION ACT 1988
CIVIL AVIATION 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 French DGAC has issued AD F-2005-040 affecting Airbus A330 model aircraft. France is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/A330/49, which will become effective on 12 May 2005.
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 Section Head - Airframes, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate the aviation industry in Australia and to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to make regulations for the purposes of the Act and in the interests of the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, provide that the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for kinds of aircraft or aeronautical products. An AD is a legislative instrument and is a means by which the State of Design provides information necessary to ensure the continuing airworthiness of an aircraft type. The State of Registry of an individual aircraft is responsible for its continuing airworthiness and 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.
Scope and Application
The Civil Aviation Act 1988 applies to the safety and regulation of civil aviation within Australia, encompassing both domestic and international operations. The Act empowers the Governor-General to enact regulations, such as the Civil Aviation Safety Regulations 1998, which delegate the Civil Aviation Safety Authority (CASA) with the authority to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. ADs are legislative instruments that mandate requirements for maintaining the airworthiness of aircraft and are integral to the continuing airworthiness responsibilities of the State of Design and the State of Registry. These directives are designed to ensure compliance with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, which governs the airworthiness of aircraft. The application of ADs is a crucial mechanism for Australia to uphold its obligations under the Convention and ensure the safety of aircraft within its jurisdiction. Notably, while ADs are subject to disallowance under the Acts Interpretation Act 1901 and are considered legislative instruments under the Legislative Instruments Act 2003, they typically do not require public consultation or a Regulatory Impact Statement as they are issued in response to international directives and obligations.
Key Provisions
The Civil Aviation Act 1988, as amended and supplemented by the Civil Aviation Regulations 1998, facilitates the issuance of airworthiness directives (ADs) under section 98 and regulation 39.001 respectively. Section 98 empowers the Governor-General to make regulations that align with the Act's objectives, particularly the safety of air navigation. Regulation 39.001 further specifies that the Civil Aviation Safety Authority (CASA) can issue ADs for certain types of aircraft or aeronautical products, making them a legislative instrument as defined by the Legislative Instruments Act 2003. These directives are critical tools for maintaining the continuing airworthiness of aircraft, ensuring that they meet safety standards throughout their operational life.
The obligations imposed by the Act and the regulations on the parties involved, particularly CASA, are significant. CASA, as the national airworthiness authority, is tasked with assessing any ADs issued by the State of Design and determining whether an Australian AD is necessary. This involves a rigorous evaluation process to ensure that any safety concerns identified by the State of Design are adequately addressed within the Australian regulatory framework. The State of Design, in this case, France for the Airbus A330, bears the primary responsibility for ensuring the continuing airworthiness of the aircraft type. CASA must then issue a corresponding AD to mandate the requirements for the Australian Register, ensuring that all aircraft of that type registered in Australia comply with the safety standards specified in the AD.
Failure to comply with the requirements of an airworthiness directive can result in serious consequences. The Civil Aviation Act 1988 and associated regulations do not explicitly detail the penalties for non-compliance with ADs, but such violations can lead to severe civil or criminal penalties. These may include fines and imprisonment, as stipulated in other relevant aviation and safety legislation. The gravity of these penalties underscores the importance of adhering to ADs, which are designed to prevent accidents and ensure the highest standards of air safety. Non-compliance not only jeopardises the safety of the aircraft but also the lives of passengers and crew, making adherence to ADs a critical aspect of aviation regulation.
