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 2008-09-18 affecting Taylorcraft aircraft. The USA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/TAYLORCRAFT/2, which will become effective on 6 June 2008.
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 Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Manager, Airframes in the Airworthiness Engineering Branch, 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 civil aviation in Australia, addressing the need for safety and efficiency in the sector. Under this Act, the Civil Aviation Safety Regulations 1998 were established to ensure that aircraft and aeronautical products meet the required safety standards. A significant aspect of these regulations is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). ADs are legislative instruments that mandate specific actions to maintain the airworthiness of aircraft, and they are critical for ensuring compliance with international standards set by the Convention on International Civil Aviation. In this context, CASA has issued AD/TAYLORCRAFT/2 in response to an AD from the United States Federal Aviation Administration (FAA) concerning Taylorcraft aircraft. This AD was made to fulfil Australia's international obligations and was issued without public consultation, as it is a direct response to an AD from the relevant State of Design. The AD was drafted by the Manager, Airframes in the Airworthiness Engineering Branch of CASA, in accordance with the legislative powers granted under the Civil Aviation Act 1988.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended, provide the regulatory framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments made under the authority of the Civil Aviation Act 1988, specifically pursuant to section 98 and regulation 39.001. ADs apply to all aircraft and aeronautical products registered in Australia, and their purpose is to ensure the continuing airworthiness of these items as mandated by Annex 8 to the Convention on International Civil Aviation. The State of Design has the primary responsibility for continuing airworthiness, and CASA, as Australia's national airworthiness authority, must assess and, if necessary, issue corresponding ADs for aircraft registered in Australia. Exemptions or exclusions from these regulations are not detailed in the explanatory statement, but the ADs themselves may include specific conditions or limitations as necessary. The ADs are issued without public consultation as they respond to international obligations and are based on directives from the relevant State of Design. The ADs are not subject to a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, particularly section 98, empower the Governor-General to make regulations for the safety of air navigation. This authority is exercised through the Civil Aviation Safety Regulations 1998, with regulation 39.001 specifically enabling the issuance of airworthiness directives (ADs) by CASA for certain types of aircraft or aeronautical products. According to subregulation 39.001(5), an AD is classified as a disallowable instrument under section 46A of the Acts Interpretation Act 1901, making it a legislative instrument as per section 6 of the Legislative Instruments Act 2003.
The obligations and requirements imposed by the Act and its regulations on the parties involved are significant. The State of Design holds primary responsibility for the continuing airworthiness of an aircraft type and must provide all necessary information to the appropriate States of Registry, as stipulated in Annex 8 to the Convention on International Civil Aviation. The State of Registry, which in this context is Australia, must then develop or adopt requirements to ensure the continuing airworthiness of the aircraft. When the State of Design issues an AD, such as AD 2008-09-18 for Taylorcraft aircraft, CASA must evaluate this information and, if necessary, issue a corresponding Australian AD to enforce the State of Design's requirements.
The issuance of ADs like AD/TAYLORCRAFT/2 is governed by international obligations under the Convention on International Civil Aviation and in response to directives from the relevant State of Design. This process does not necessitate public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD is formally made by the Manager, Airframes in the Airworthiness Engineering Branch on behalf of CASA, in accordance with subsection 84A(2) of the Civil Aviation Act 1988.
Regarding offences, penalties, and consequences for breaches, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 impose strict compliance requirements. Failure to adhere to the mandated airworthiness directives can result in significant civil or criminal consequences, depending on the severity of the breach. While the specific penalties are not detailed in the provided text, non-compliance with ADs can lead to actions such as fines, suspension or revocation of aircraft certificates, or even criminal charges in cases of gross negligence or wilful disregard of safety regulations. The exact penalties would be outlined in the relevant sections of the Civil Aviation Act 1988 and associated regulations.
