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.
Transport Canada has issued CF-2004-17R1, affecting Bell Helicopter Textron Canada (BHTC) Model 407 Series helicopters. Canada is the State of Design for this type. In response to Transport Canada issuing CF-2004-17R1, CASA has issued AD/BELL 407/28 Amendment 1, which will become effective on 7 July 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 regulate the safety and efficiency of civil aviation within Australia. The Act provides the framework for the creation of regulations and standards that ensure the safety of air navigation and aircraft. In the interests of maintaining safety, the Act empowers the Governor-General to make regulations, which includes the issuance of airworthiness directives through the Civil Aviation Safety Regulations 1998. This legislative measure responds to the need for uniform and internationally compliant standards to ensure the ongoing airworthiness of aircraft and aeronautical products. The Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are legislative instruments that mandate compliance with certain safety requirements. The process of issuing such directives is driven by international obligations under the Convention on International Civil Aviation and is intended to align Australian regulations with those of other contracting states, ensuring a consistent approach to aircraft safety on a global scale.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs) which are legislative instruments designed to ensure the safety of aircraft in operation. Specifically, the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue ADs for particular types of aircraft or aeronautical products, in accordance with international standards as outlined in Annex 8 to the Convention on International Civil Aviation. These ADs apply to the persons or entities that hold a Certificate of Airworthiness for the relevant aircraft type and are responsible for ensuring the continuing airworthiness of their aircraft. The geographic reach of these ADs is national, impacting all aircraft registered in Australia. The regulations do not specify exclusions or exemptions for particular aircraft or entities, except as may be determined by CASA in the context of individual ADs. The application of these regulations can be extended or restricted through subordinate instruments, such as specific ADs, which are issued in response to safety concerns identified by the State of Design or other relevant authorities.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) through regulation 39.001 (subsection 5) (1). The Governor-General has the authority to make regulations under section 98 of the Act, and the Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. An AD is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003, and is subject to disallowance as per section 46A of the Acts Interpretation Act 1901. These directives are instrumental in ensuring the continuing airworthiness of aircraft, a responsibility that falls upon the State of Design and the State of Registry as per Annex 8 to the Convention on International Civil Aviation.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998 on CASA and other entities are significant. CASA, as Australia's national airworthiness authority, is tasked with assessing ADs issued by the State of Design, such as Transport Canada in the case of the Bell Helicopter Textron Canada (BHTC) Model 407 Series helicopters, and issuing Australian ADs if deemed necessary. The State of Registry must also develop or adopt requirements to ensure the continuing airworthiness of aircraft on the Australian Register. These obligations ensure that aircraft meet international safety standards and that the Australian public is protected by maintaining high standards of airworthiness.
Breaches of the requirements set out in the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998 can lead to serious consequences. While the specific offences and penalties are not detailed in the provided text, it is clear that compliance with ADs is mandatory. Failure to adhere to ADs could potentially result in aircraft being deemed unairworthy, which could lead to civil or criminal penalties under Australian law. The exact nature and severity of these penalties would depend on the specific circumstances of the breach and the provisions of the relevant aviation legislation.
