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 Civil Aviation Safety Authority or its predecessors issued AD/AA-1/6 affecting Gulfstream AA-1 model aircraft. CASA has assessed this AD and as a result has cancelled AD/AA-1/6. The cancellation will become effective on 4 June 2009. No replacement AD is required, as the unsafe condition no longer exists.
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, 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, enacted to establish and maintain a robust framework for the regulation of civil aviation in Australia, aims to ensure the safety and efficiency of air navigation. The Act empowers the Governor-General to create regulations that serve the interests of safety, which includes the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives, being legislative instruments under the Legislative Instruments Act 2003, mandate specific requirements for the continuing airworthiness of aircraft. In compliance with international obligations, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, CASA is responsible for assessing ADs issued by the State of Design and, where necessary, issuing corresponding Australian ADs. The Civil Aviation Safety Authority has determined that AD/AA-1/6 for Gulfstream AA-1 model aircraft, previously issued, is no longer required and has been cancelled, reflecting the resolution of the previously identified unsafe condition. The cancellation of this AD, which became effective on 4 June 2009, was made without public consultation, in line with Australia’s international commitments, and was deemed not to require a Regulatory Impact Statement.
Scope and Application
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, which are critical for ensuring the safety of aircraft registered in Australia. These regulations apply to the Civil Aviation Safety Authority (CASA) as the national airworthiness authority, and their scope includes the assessment and potential issuance of ADs based on the continuing airworthiness of aircraft types, particularly those designed in Australia or subject to international agreements under the Convention on International Civil Aviation. This Act and its associated regulations apply to all aircraft registered in Australia, as well as to any entities involved in the operation, maintenance, and oversight of these aircraft. The geographic reach of this legislation is national, as it pertains to the regulation of civil aviation within Australia. Subordinate instruments, such as ADs, extend the application of the Act and the Regulations, but are subject to disallowance and review processes as legislative instruments. Exemptions or exclusions from the application of ADs are not explicitly detailed in the provided text, but such exclusions would typically be governed by the specific conditions outlined in individual ADs or related regulations.
Key Provisions
The main operative sections of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 pertain to the issuance of airworthiness directives (ADs). Specifically, section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in the interests of air navigation safety, while 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. Furthermore, subregulation 39.001(5) of the Civil Aviation Safety Regulations 1998 establishes that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, and thus, a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
The Act and its regulations impose obligations and requirements on CASA and other relevant parties, ensuring the safety and airworthiness of aircraft. For instance, under Annex 8 to the Convention on International Civil Aviation, the State of Design has the overall responsibility for the continuing airworthiness of an aircraft type, while the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of individual aircraft. CASA, as Australia's national airworthiness authority, must assess information from the State of Design and issue an Australian AD when necessary. Additionally, the Act and its regulations require CASA to consult with the Australian public and the Office of Best Practice Regulation when necessary, although in this specific case, no such consultation was required.
In terms of civil and criminal consequences, breaches of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 may result in various offences and penalties. While the specific maximum penalties are not stated in the provided text, it is clear that non-compliance with ADs and airworthiness requirements could lead to legal repercussions. CASA, as the enforcing authority, would be responsible for imposing these penalties and ensuring adherence to the regulations. The consequences may include fines, imprisonment, or both, depending on the severity of the breach and the specific provisions of the Act and its regulations.
