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 US FAA has issued AD 2006-23-14 affecting Air Tractor AT 500 model aircraft. The USA is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/AT/28, which will become effective on 18 January 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, 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 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, addressing the need for stringent safety standards and effective governance in the aviation industry. The Act empowers the Governor-General to make regulations, including the issuance of airworthiness directives, to ensure the safety of air navigation. The Civil Aviation Safety Regulations 1998 further detail the regulatory mechanisms, with regulation 39.001 authorising the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specific types of aircraft or aeronautical products. This regulatory framework is designed to align with international standards, particularly those set by the International Civil Aviation Organization (ICAO), ensuring that Australia meets its international obligations and maintains high safety standards.
The Civil Aviation Safety Regulations 1998 also establish that airworthiness directives are legislative instruments subject to disallowance under the Acts Interpretation Act 1901. This legislative process is intended to maintain the integrity and safety of the nation’s airspace while ensuring compliance with international obligations. The Civil Aviation Act 1988 and the associated regulations are enacted by the Australian Parliament and are driven by the overarching policy objective of ensuring the highest possible standards of safety in civil aviation, both domestically and internationally.
Scope and Application
The Civil Aviation Act 1988 and its associated regulations, including the Civil Aviation Safety Regulations 1998, govern the safety of air navigation in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products. These ADs are legislative instruments under the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The ADs are critical for ensuring the continuing airworthiness of aircraft, a responsibility that falls under the purview of the State of Design and the State of Registry, as stipulated in Annex 8 of the Convention on International Civil Aviation. For instance, when the US FAA issued AD 2006-23-14 concerning Air Tractor AT 500 model aircraft, CASA assessed the directive and issued Australian AD/AT/28, which will be effective from 18 January 2007. Notably, given the international obligations under the Convention on International Civil Aviation, no public consultation was required for this AD, and it has been determined that such ADs do not necessitate a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 (section 98) provides the framework for the regulation of civil aviation safety in Australia, allowing the Governor-General to make regulations for the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for types of aircraft or aeronautical products. An AD is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003, and it is a disallowable instrument as per section 46A of the Acts Interpretation Act 1901.
Under the Civil Aviation Safety Regulations 1998, CASA is tasked with the responsibility of ensuring the continuing airworthiness of aircraft on the Australian Register. When a State of Design, such as the United States in this case, issues an AD for a type of aircraft, CASA must assess the information and, if appropriate, issue a corresponding AD in Australia. This ensures that Australian aircraft meet the necessary safety standards set by the international aviation community. The AD issued by CASA, such as AD/AT/28 for the Air Tractor AT 500 model, reflects these international obligations and requirements.
The obligations imposed on parties governed by the Act include the State of Design's responsibility to provide necessary information to ensure the continuing airworthiness of an aircraft type, as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Registry, in this case, CASA, must then assess this information and issue an Australian AD if necessary to maintain the safety standards. This process ensures that all aircraft within Australian jurisdiction meet the required safety criteria and comply with international standards.
Failure to comply with an airworthiness directive can lead to various civil or criminal consequences, depending on the severity of the breach. Under section 98 of the Civil Aviation Act 1988, non-compliance with CASA regulations can result in penalties, which may include fines and imprisonment. However, the specific penalties for breaching an AD are not detailed in the provided text, and further consultation of the Act and associated regulations would be necessary to determine the exact maximum penalties applicable. The importance of adhering to these directives cannot be overstated, as they are fundamental to ensuring the safety of air navigation in Australia.
