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/BELL 206/88 affecting Bell 206L-1 model aircraft. CASA has assessed this AD and as a result has cancelled it. The cancellation will become effective on 23 October 2008. 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 was enacted to establish a legislative framework for the regulation of civil aviation in Australia, addressing the need for a comprehensive system to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, a role delegated to the Civil Aviation Safety Authority (CASA) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. This regulation allows CASA to issue airworthiness directives, a legislative instrument that ensures compliance with international standards for the continuing airworthiness of aircraft, as mandated by Annex 8 of the Convention on International Civil Aviation. The policy objective is to maintain high safety standards in line with global best practices, ensuring that all aircraft registered in Australia meet necessary safety criteria.
Scope and Application
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products, thereby ensuring the safety of air navigation. Under the authority granted by section 98 of the Act, and specifically through regulation 39.001 of the Civil Aviation Safety Regulations 1998, CASA can mandate requirements for the continuing airworthiness of aircraft registered in Australia, in compliance with international standards set by the International Civil Aviation Organization (ICAO). These directives are legislative instruments and fall under the scrutiny of the Legislative Instruments Act 2003. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to the State of Registry to ensure continued airworthiness. In Australia, CASA assumes the role of the national airworthiness authority, tasked with assessing information from the State of Design and, if necessary, issuing Australian ADs to enforce the required safety measures. In the specific case of AD/BELL 206/88 affecting Bell 206L-1 model aircraft, CASA has cancelled the directive, effective from 23 October 2008, due to the resolution of the unsafe condition it was intended to address. This cancellation, made in accordance with the Convention on International Civil Aviation, did not require public consultation or a Regulatory Impact Statement, and was issued by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, as amended by the Civil Aviation Safety Regulations 1998, pertain to the issuance and management of airworthiness directives (ADs) (sections 98 and 39.001). Under section 98, the Governor-General is empowered to make regulations to ensure the safety of air navigation, while regulation 39.001 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Furthermore, subregulation 39.001(5) clarifies that an AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901, thereby classifying it as a legislative instrument in accordance with section 6 of the Legislative Instruments Act 2003.
The obligations imposed by the Act and the Regulations include the responsibility of the State of Design to ensure the continuing airworthiness of an aircraft type and to provide necessary information to the States of Registry. This obligation is further detailed under Annex 8 to the Convention on International Civil Aviation. The State of Registry, such as CASA in Australia, must develop or adopt requirements to ensure the continuing airworthiness of aircraft. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue a corresponding Australian AD to enforce the requirements. This process ensures that any safety concerns identified by the State of Design are adequately addressed in Australia.
In the case of the AD/BELL 206/88 concerning Bell 206L-1 model aircraft, CASA has assessed the directive and subsequently decided to cancel it. This decision aligns with Australia's obligations under the Convention on International Civil Aviation and reflects that the unsafe condition previously identified no longer exists. Consequently, no replacement AD is required. Given the nature of the AD cancellation, there was no consultation with the Australian public, and the Office of Best Practice Regulation has determined that a Regulatory Impact Statement is not necessary. The cancellation was issued 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.
For breaches of the provisions concerning ADs, the Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 provide for both civil and criminal penalties. Entities failing to comply with ADs may face substantial fines and, in more severe cases, imprisonment. The maximum penalties are determined by the specific nature of the breach and the level of non-compliance, reflecting the serious implications such breaches can have on aviation safety. These penalties underscore the importance of adhering to ADs to maintain the safety standards required in the aviation industry.
