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 UK CAA has issued AD G-2005-0014 affecting BAe 146 aircraft. The UK is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/BAe 146/115, which will become effective on 4 August 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 - Systems, 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 establish a comprehensive regulatory framework for civil aviation in Australia, addressing the need for effective oversight and safety standards in the aviation industry. Under section 98 of the Act, the Governor-General is empowered to create regulations aimed at ensuring the safety of air navigation, with the Civil Aviation Safety Regulations 1998 subsequently detailing the mechanisms for issuing airworthiness directives. The problem or gap this legislation addresses includes the need for consistent international standards and domestic regulations to ensure that aircraft maintain their airworthiness and safety throughout their operational lifespan, aligning with international conventions such as Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 enable the Civil Aviation Safety Authority (CASA) to issue these directives, which are legislative instruments as defined under the Legislative Instruments Act 2003. This legislative framework ensures that CASA, as Australia’s national airworthiness authority, can mandate necessary safety requirements for aircraft registered in Australia, thereby fulfilling Australia’s international obligations and maintaining high safety standards domestically.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Safety Regulations 1998, establishes the framework for the regulation of civil aviation activities within Australia. Under this legislative structure, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products, as per regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments and are critical in maintaining the safety and airworthiness of aircraft operating in Australia. The Act applies to all aircraft registered in Australia and those entities involved in the manufacture, maintenance, or operation of such aircraft, ensuring compliance with both national and international aviation safety standards. The geographic reach of the Act is national, with CASA acting as the central authority responsible for enforcing these regulations throughout Australia. While the Act broadly applies to all relevant aircraft and entities, certain exclusions or exemptions may apply depending on specific circumstances or other regulatory provisions. The application of the Act can be further extended or specified through subordinate instruments, which provide detailed operational guidelines and standards necessary for the enforcement of airworthiness directives.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for the issuance and enforcement of airworthiness directives (ADs). Section 98 of the Act allows the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Regulations enables the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These directives are intended to maintain or restore airworthiness of aircraft and are critical in ensuring safety standards are met globally. The ADs are considered legislative instruments under the Legislative Instruments Act 2003, which means they have legal force and must be adhered to by relevant parties.
The Act and the Regulations impose several obligations on the parties involved. The State of Design, which is the country responsible for designing the aircraft, has the responsibility to provide necessary information to ensure the continuing airworthiness of the aircraft type. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the aircraft's airworthiness. CASA, as Australia’s national airworthiness authority, is tasked with assessing any ADs issued by the State of Design and determining whether an Australian AD is necessary. If an AD is issued by the State of Design, CASA must issue a corresponding Australian AD to mandate the requirements for aircraft registered in Australia.
Failure to comply with the requirements set forth in the ADs can result in serious consequences. While the Act does not specify particular offences or penalties for non-compliance with ADs, non-compliance can lead to significant civil or criminal liabilities. For instance, operating an aircraft that does not meet the airworthiness requirements set by an AD can result in enforcement actions by CASA, including fines, suspension, or revocation of the aircraft's certificate of airworthiness. Such actions can severely impact the operational capability of the aircraft and the legal standing of the operators. Additionally, there can be implications under other aviation-related legislation, such as the Crimes Act 1914, where serious breaches may result in criminal charges.
