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 EASA has issued AD 2007-0141-E affecting Eurocopter AS 355 series helicopters. The EASA is the State of Design for these helicopters. CASA has assessed this AD and has issued Australian AD/AS 355/96, which will become effective on 25 May 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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, New Technologies and Systems, 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 provide a comprehensive legislative framework for the regulation of civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. Under this Act, the Governor-General has the authority to make regulations for the purposes of the Act, particularly focusing on the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail these regulations, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments that mandate specific safety requirements for aircraft or aeronautical products, reflecting international standards and practices as outlined in Annex 8 to the Convention on International Civil Aviation. This legislative framework ensures that Australia adheres to its obligations under international agreements while maintaining the highest standards of aviation safety.
Scope and Application
The Civil Aviation Safety Regulations 1998, pursuant to the Civil Aviation Act 1988, grant the Civil Aviation Safety Authority (CASA) the authority to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, ensuring that these aircraft remain safe and airworthy. This legislative framework applies to entities and individuals involved in the design, manufacture, registration, and operation of aircraft within Australia, thereby affecting a broad spectrum of industries including commercial airlines, private aircraft owners, and aviation maintenance companies. The geographic reach of these regulations is national, applying uniformly across all states and territories of Australia. However, the regulations also consider international obligations under the Convention on International Civil Aviation, necessitating that CASA issue corresponding ADs when required by the State of Design. These ADs are legislative instruments that become effective as per their specified dates, and they may be subject to disallowance under the Acts Interpretation Act 1901. Importantly, while ADs are crucial for maintaining airworthiness, they do not require public consultation or a Regulatory Impact Statement, reflecting their technical nature and the international coordination involved in their issuance.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) as outlined in section 98 of the Act and regulation 39.001 of the Regulations. According to section 39.001(5) of the Regulations, an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901 and is considered a legislative instrument under the Legislative Instruments Act 2003. These provisions allow the Civil Aviation Safety Authority (CASA) to issue ADs to ensure the continuing airworthiness of aircraft types registered in Australia. Annex 8 to the Convention on International Civil Aviation specifies that the State of Design holds responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to ensure compliance by States of Registry. This places an obligation on CASA to assess ADs issued by the State of Design and, if appropriate, issue corresponding ADs for Australian registered aircraft.
The obligations imposed by the ADs are multifaceted. Firstly, the State of Design, such as the European Union Aviation Safety Agency (EASA) for the Eurocopter AS 355 series helicopters, is mandated to issue ADs to address safety concerns. These ADs must provide detailed information about the necessary corrective actions or modifications to maintain the airworthiness of the aircraft. Secondly, the State of Registry, in this case, Australia, is required to assess the ADs issued by the State of Design and issue corresponding ADs if necessary. This ensures that Australian-registered aircraft comply with international safety standards. CASA, as Australia's national airworthiness authority, must rigorously evaluate the ADs and issue Australian ADs, such as AD/AS 355/96, to mandate the necessary requirements.
Failure to comply with the ADs can result in significant legal consequences. Under the Civil Aviation Act 1988, non-compliance with an AD may constitute an offence. The Act provides that an AD is enforceable, and failure to comply with its terms can lead to criminal penalties. Additionally, the Civil Aviation Safety Regulations 1998 may specify particular penalties for non-compliance, which can include fines and potential imprisonment. The severity of the penalties is intended to ensure that all parties adhere to the mandated safety requirements to prevent accidents and ensure the safety of air navigation.
