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 United States FAA has issued AD 2008-26-10 affecting Cessna 170 series aeroplanes. The United States is the State of Design for this aeroplane series. CASA has assessed this AD and has issued Australian AD/CESSNA 170/85, which will become effective on 16 January 2009.
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, Systems and New Technologies, in the Airworthiness Engineering Group, 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, ensuring the safety and efficiency of air navigation. Section 98 of this Act empowers the Governor-General to make regulations for the purposes of the Act, particularly with regard to the safety of air navigation. The Civil Aviation Safety Regulations 1998, which were made under this Act, include provisions for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). An AD is a legislative instrument that becomes effective in accordance with international standards and Australia's obligations under the Convention on International Civil Aviation. The issuance of ADs is critical for maintaining the continuing airworthiness of aircraft and ensuring compliance with safety standards set by the State of Design and the State of Registry. Given the international nature of civil aviation and the need for harmonised safety measures, ADs are issued in response to directives from relevant States of Design, such as the United States in the case of the Cessna 170 series aeroplanes, and are implemented by CASA to mandate specific requirements on the Australian Register.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework within which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation in Australia. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for kinds of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003 and are intended to ensure the continuing airworthiness of aircraft, as per the obligations set out in Annex 8 to the Convention on International Civil Aviation. The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, and ADs are the primary means by which this information is disseminated. In Australia, CASA, as the national airworthiness authority, must assess any relevant ADs issued by the State of Design and, if appropriate, issue corresponding Australian ADs. This ensures that Australian aircraft comply with international safety standards and obligations. The issuance of ADs does not require public consultation or a Regulatory Impact Statement, as it is directly tied to Australia's international commitments and the directives issued by the relevant State of Design.
Key Provisions
The Civil Aviation Act 1988 (section 98) empowers the Governor-General to enact regulations aimed at ensuring the safety of air navigation. One such 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. This regulatory framework is designed to maintain high safety standards in civil aviation by ensuring that aircraft meet certain airworthiness criteria. It is also stipulated that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, which classifies it as a legislative instrument.
The obligations imposed by the Civil Aviation Safety Regulations 1998 are significant for both the State of Design and the State of Registry. The State of Design, such as the United States in the case of the Cessna 170 series, holds the primary responsibility for the continuing airworthiness of a particular aircraft type. This includes providing all necessary information to the States of Registry to ensure that the aircraft can maintain their airworthiness. The State of Registry, which for Australian aircraft is CASA, must then develop or adopt requirements to ensure the continuing airworthiness of the aircraft registered within their jurisdiction. When a State of Design issues an AD, CASA must review the directive and, if necessary, issue a corresponding Australian AD to enforce the requirements specified by the State of Design.
In the case of the Cessna 170 series, the United States issued AD 2008-26-10, which CASA assessed and subsequently issued as Australian AD/CESSNA 170/85. This AD is set to become effective on 16 January 2009. Given that this directive arises from Australia’s commitments under the Convention on International Civil Aviation and is a direct response to an AD issued by the relevant State of Design, no public consultation was conducted. Furthermore, the Office of Regulatory Review has determined that such ADs do not necessitate a Regulatory Impact Statement. The AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in compliance with subsection 84A(2) of the Act.
In terms of legal consequences, any breach of the requirements set out in an airworthiness directive can have serious implications. The Civil Aviation Safety Regulations 1998 provide that failure to comply with an AD can result in civil or criminal penalties. These may include fines and, in severe cases, imprisonment. The maximum penalties can vary depending on the nature and severity of the breach, but they are intended to ensure strict adherence to airworthiness standards to protect public safety. The overarching objective is to maintain the highest standards of aviation safety and to mitigate any potential risks associated with aircraft operation.
