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 EASA has issued AD 2007-0223R2, affecting Dowty Aerospace R408 series propellers. EASA acts on behalf of the United Kingdom which is the State of Design for this type. CASA has amended the equivalent Australian AD to AD/PR/37 Amendment 1 which will become effective on 20 December 2007. This AD cancels and replaces the previous issue.
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 Acting Manager, Systems in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, aims to regulate civil aviation in Australia with a focus on safety and security. It provides the legal framework for the issuance of regulations and directives to ensure airworthiness, among other aspects of civil aviation. The Act enables the Governor-General to make regulations for the safety of air navigation, including the issuance of airworthiness directives by the Civil Aviation Safety Authority (CASA). The Civil Aviation Safety Regulations 1998, which were also enacted under the authority of the Civil Aviation Act 1988, further detail the requirements for airworthiness directives and their implementation. These regulations allow CASA to issue directives that address specific types of aircraft or aeronautical products, ensuring that they continue to meet the necessary safety standards. This legislative framework addresses the need for a coordinated and internationally compliant approach to managing the continuing airworthiness of aircraft registered in Australia, fulfilling Australia’s obligations under the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Act 1988 applies to the regulation of civil aviation in Australia, including the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Under section 98 of this Act, the Governor-General may make regulations for the purposes of the Act, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically empowers CASA to issue ADs for kinds of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003. The Act and associated regulations apply to all aircraft registered in Australia and their operators, as well as to manufacturers and other entities involved in the aviation industry. The geographic reach of these regulations is national, covering all Australian territory and its airspace. There are no specific exclusions or exemptions mentioned in the provided text, but the application of ADs may vary depending on the specific circumstances and requirements of individual aircraft or aeronautical products. The Act also acknowledges the role of the State of Design in ensuring continuing airworthiness, with CASA required to issue Australian ADs in response to directives from the relevant State of Design, such as the European Aviation Safety Agency (EASA) in this case.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish the framework for issuing airworthiness directives (ADs) to ensure the safety of aircraft in Australian airspace. Section 98 of the Act empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products (ss 39.001(1)-(4)). Notably, subregulation 39.001(5) stipulates that ADs are disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are considered legislative instruments pursuant to section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the ADs are primarily on CASA, as Australia’s national airworthiness authority, and on the State of Registry of individual aircraft. According to Annex 8 to the Convention on International Civil Aviation, the State of Design has the overarching responsibility for the continuing airworthiness of an aircraft type, including the duty to provide necessary information to the States of Registry. CASA must assess any ADs issued by the State of Design and, if necessary, issue an Australian AD to ensure compliance with the State of Design’s requirements. The State of Registry, on the other hand, must develop or adopt requirements to maintain the continuing airworthiness of aircraft within its jurisdiction.
In terms of potential breaches and consequences, the Civil Aviation Safety Regulations 1998 and associated ADs do not explicitly list offences, penalties, or consequences for non-compliance within the provided text. However, it is understood that failing to comply with an AD could lead to severe safety risks and potential legal repercussions. While the specific penalties are not detailed in the text, non-compliance with aviation safety regulations could result in fines, enforcement actions, or even grounding of aircraft, all of which are critical to maintaining the high safety standards required in the aviation industry. The text does indicate that the AD has been issued in response to obligations under international conventions and does not require public consultation or a Regulatory Impact Statement.
