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 206/3 affecting Bell 206A 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, Airframes 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 provide a legal framework for the regulation of civil aviation in Australia, ensuring safety and efficiency within the sector. The Act empowers the Governor-General to make regulations that safeguard air navigation, with a particular focus on airworthiness. In line with this objective, the Civil Aviation Safety Regulations 1998 allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that are legally binding instruments aimed at maintaining the airworthiness of aircraft and aeronautical products. These ADs serve as a crucial mechanism for ensuring that aircraft meet safety standards, in accordance with Australia's international obligations under the Convention on International Civil Aviation. CASA, as Australia’s national airworthiness authority, has the responsibility to assess ADs issued by the State of Design and, when necessary, issue corresponding Australian ADs to mandate compliance with safety requirements. This legislative framework ensures that both the State of Design and the State of Registry maintain their respective responsibilities for the continuing airworthiness of aircraft registered in Australia.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products, ensuring the safety of air navigation as stipulated under section 98 of the Act. These regulations apply to all aircraft registered in Australia, irrespective of the aircraft's nationality, and involve a broad range of aviation entities and individuals, including aircraft operators, manufacturers, and maintenance service providers. The ADs are legislative instruments as per section 46A of the Acts Interpretation Act 1901 and are subject to disallowance under the Legislative Instruments Act 2003. These directives are essential for maintaining the continuing airworthiness of aircraft, aligning with international standards set forth by the International Civil Aviation Organization (ICAO) and the Convention on International Civil Aviation. The ADs are issued based on assessments by CASA, which acts on behalf of Australia's obligations under international conventions, ensuring compliance with airworthiness standards both domestically and internationally.
Key Provisions
The Civil Aviation Act 1988, under section 98, empowers the Governor-General to establish regulations that support the Act's objectives, particularly in ensuring the safety of air navigation. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 permits the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901 and are classified as legislative instruments in accordance with section 6 of the Legislative Instruments Act 2003. The ADs are intended to ensure that aircraft maintain their airworthiness, and they are issued in line with Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the initial airworthiness of an aircraft type, must provide necessary information to ensure its continuing airworthiness. Meanwhile, the State of Registry, in this case CASA acting on behalf of Australia, must assess this information and issue an Australian AD if appropriate.
Under these provisions, CASA is obligated to review and assess any ADs issued by the State of Design that pertain to aircraft registered in Australia. If an unsafe condition is identified, CASA must issue a corresponding AD to ensure the aircraft comply with necessary safety standards. In this particular instance, CASA assessed AD/BELL 206/3, which affected Bell 206A model aircraft, and decided to cancel it because the unsafe condition no longer existed. This decision aligns with Australia’s obligations under the Convention on International Civil Aviation. Given that the cancellation was a result of international obligations, no public consultation was required. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The Manager, Airframes in the Airworthiness Engineering Group, made this AD cancellation on behalf of CASA in accordance with subsection 84A(2) of the Act.
Failure to comply with the requirements set out in an airworthiness directive can result in significant legal consequences. CASA, as the national airworthiness authority, has the power to enforce compliance through various measures, including the suspension or revocation of an aircraft's certificate of airworthiness. Such actions can prevent an aircraft from operating until the necessary modifications or inspections are completed. Additionally, individuals or entities found in breach of ADs may face civil or criminal penalties. Under the Civil Aviation Act 1988, offences can attract fines and imprisonment. For instance, knowingly causing an aircraft to be flown in a state that does not comply with an AD can result in substantial penalties. The maximum fines and imprisonment terms depend on the severity of the breach and the specific provisions of the Act and related regulations. The overarching aim of these provisions and penalties is to ensure that all aircraft meet the required safety standards, thereby protecting public safety and maintaining the integrity of Australia’s civil aviation system.
