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 206/70 Amendment 2 affecting Bell 206 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, enacted by the Commonwealth Parliament, is a fundamental piece of legislation designed to ensure the safety and efficiency of civil aviation within Australia. One of its key mechanisms is the issuance of airworthiness directives, which are regulatory tools used to mandate safety improvements and ensure compliance with safety standards for aircraft and aeronautical products. The Act empowers the Civil Aviation Safety Authority (CASA) to issue these directives to maintain and enhance the safety of air navigation, aligning with the overarching objective of ensuring the highest standards of airworthiness and safety in Australian civil aviation. The Civil Aviation Safety Regulations 1998 further detail the process and authority for CASA to issue these directives, reinforcing the commitment to safety as mandated by the Convention on International Civil Aviation.
Scope and Application
The Civil Aviation Safety Regulations 1998 under the Civil Aviation Act 1988 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products to ensure the safety of air navigation. An AD is a legislative instrument that falls under the purview of the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. This legislative framework is designed to ensure that all relevant states, particularly the State of Registry, uphold the continuing airworthiness of aircraft in accordance with Annex 8 of the Convention on International Civil Aviation. CASA, as Australia's national airworthiness authority, must assess ADs issued by the State of Design and may issue corresponding Australian ADs if necessary. In the case of AD/BELL 206/70 Amendment 2, CASA assessed and subsequently cancelled the AD for Bell 206 model aircraft, effective 23 October 2008, due to the resolution of the unsafe condition identified. This cancellation aligns with Australia's international obligations, thereby obviating the need for public consultation or a Regulatory Impact Statement. The AD was made by the Manager, Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in compliance with the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft in Australia. Under section 98 of the Act, the Governor-General has the authority to make regulations, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as legislative instruments, as outlined in subregulation 39.001(5) and section 6 of the Legislative Instruments Act 2003.
The State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, as stipulated in Annex 8 to the Convention on International Civil Aviation. This includes providing necessary information to the States of Registry to ensure the safety of aircraft. In Australia, CASA acts as the national airworthiness authority and is tasked with assessing information from the State of Design and, if necessary, issuing an Australian AD to enforce the requirements of the State of Design. The State of Registry, in this case CASA, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered in Australia.
In the specific case of the Bell 206 model aircraft, CASA issued AD/BELL 206/70 Amendment 2, which was subsequently cancelled due to the resolution of the unsafe condition. This cancellation, in compliance with Australia’s obligations under the Convention on International Civil Aviation, means that no consultation with the public was required. Additionally, the Office of Best Practice Regulation has determined that such ADs do not necessitate a Regulatory Impact Statement. The Manager, Systems and New Technologies in the Airworthiness Engineering Group, on behalf of CASA, issued this cancellation under subsection 84A(2) of the Act.
The implications of breaching the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 are significant. Any failure to comply with an airworthiness directive or to ensure the continuing airworthiness of an aircraft can lead to severe consequences. These may include civil penalties, criminal charges, or both, depending on the nature and severity of the breach. The maximum penalties for such breaches can be substantial, reflecting the critical importance of air safety and the high stakes involved in non-compliance. The specific penalties are detailed within the relevant sections of the legislation, and failure to adhere to ADs can result in enforcement actions by CASA or other regulatory bodies.
