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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/TPE 331/16 affecting Honeywell TPE 331 engines in 1974. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 24 September 2009. No replacement AD is required.
As this AD has been cancelled because of Australia’s obligations under the Convention on International Civil Aviation, no consultation with the Australian public has taken place on this AD cancellation. 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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to regulate civil aviation in Australia with a strong emphasis on safety and the public interest. This legislation serves to establish the legal framework for the operation of aircraft within Australian airspace and provides the basis for the creation of regulations, such as the Civil Aviation Safety Regulations 1998, which in turn allow for the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). These directives are critical in maintaining the safety standards of aircraft and aeronautical products, ensuring compliance with international obligations under the Convention on International Civil Aviation. The Act empowers the Governor-General to enact regulations in the interest of air navigation safety, while CASA, under regulation 39.001, has the authority to issue airworthiness directives as legislative instruments. The continuous airworthiness of aircraft is overseen by the State of Registry, which must adhere to the requirements established under Annex 8 of the Convention to maintain safety standards.
Scope and Application
The Civil Aviation (Airworthiness) Regulations 1998, as amended, pertain to the regulation of airworthiness directives (ADs) within the framework of the Civil Aviation Act 1988. These regulations empower the Civil Aviation Safety Authority (CASA) to issue ADs that apply to specific kinds of aircraft or aeronautical products, ensuring the continuing safety and airworthiness of these items. The regulations extend their reach across Australia, reflecting both national and international obligations under the Convention on International Civil Aviation. Notably, ADs are legislative instruments that can be disallowed under the Acts Interpretation Act 1901, and they are created in accordance with the Legislative Instruments Act 2003. The cancellation of an AD, such as AD/TPE 331/16 affecting Honeywell TPE 331 engines, is subject to Australia's international obligations and may occur without public consultation, as determined by the Office of Best Practice Regulation. The AD in question was issued by CASA or its predecessors and has been officially cancelled, effective from 24 September 2009, with no requirement for a replacement AD.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework for the issuance of airworthiness directives (ADs) in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the authority to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. This regulatory power is underscored by subregulation 39.001(5), which classifies ADs as disallowable instruments under section 46A of the Acts Interpretation Act 1901 and subsequently as legislative instruments under section 6 of the Legislative Instruments Act 2003. This legislative classification highlights the formal and binding nature of ADs in ensuring the safety and airworthiness of aircraft.
The obligations imposed by these regulations require CASA to ensure the continuing airworthiness of aircraft through the issuance of ADs. Under Annex 8 to the Convention on International Civil Aviation, the State of Design holds the overarching responsibility for the continuing airworthiness of an aircraft type, mandating it to provide necessary information to States of Registry. The State of Registry, in turn, must implement or adopt requirements to maintain the airworthiness of individual aircraft. This international framework is mirrored in Australian regulations, where CASA plays a pivotal role in issuing ADs that are integral to maintaining the safety standards of aircraft operating within Australia.
Furthermore, these regulations place specific obligations on CASA to ensure that ADs are issued and managed in accordance with international standards and obligations. For instance, the cancellation of AD/TPE 331/16 affecting Honeywell TPE 331 engines, which CASA reviewed and decided to cancel effective 24 September 2009, illustrates the regulatory process. Given Australia's commitments under the Convention on International Civil Aviation, no public consultation was required for this cancellation, and the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement.
The consequences of non-compliance with ADs are significant. Failure to adhere to ADs can lead to serious safety risks, and CASA has the authority to enforce compliance through various means, including imposing penalties. While the specific penalties for non-compliance with ADs are not detailed in the provided text, it is understood that such breaches can result in severe civil and criminal consequences, reflecting the critical importance of air safety regulations.
