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, the Civil Aviation Safety Authority (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.
CASA or its predecessors issued AD/L.40/5 affecting Meta Sokol L.40 aircraft. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 27 August 2009. No replacement AD is required.
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, Future Technology and Regulatory Trends, in the Standards Development and Future Technology Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a legislative framework for the safety and efficiency of civil aviation in Australia. This Act empowers the Governor-General to make regulations that serve the interests of safe air navigation, which is essential for maintaining public confidence and ensuring the safety of all persons in and around aircraft. The Civil Aviation Safety Regulations 1998 further elaborate on these provisions, specifically allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These ADs are crucial for maintaining the continuing airworthiness of aircraft, a responsibility that is shared between the State of Design and the State of Registry under the Convention on International Civil Aviation. The Civil Aviation Safety Regulations also classify ADs as disallowable instruments, thereby recognising their regulatory significance. The legislative process for issuing such directives is overseen by CASA, ensuring that the safety and operational standards are consistently met in the Australian civil aviation sector.
Scope and Application
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the framework for the issuance of airworthiness directives (ADs) in Australia. Under this legislation, the Civil Aviation Safety Authority (CASA) is authorised to issue ADs for specific kinds of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs are legislative instruments and must comply with the requirements set out in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. The geographic scope of these regulations is national, applying to all aircraft and aeronautical products registered within Australia. However, the application of these ADs is also influenced by international obligations under the Convention on International Civil Aviation, particularly Annex 8, which assigns responsibility for the continuing airworthiness of aircraft to both the State of Design and the State of Registry. This means that ADs issued in Australia must align with the international standards and practices agreed upon by the International Civil Aviation Organization (ICAO). The ADs are intended to ensure the safety and airworthiness of aircraft, and their issuance, modification, or cancellation is subject to Australia's adherence to international conventions.
Key Provisions
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. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 specifically allows the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. This regulatory structure ensures that ADs are a critical tool for maintaining the safety and airworthiness of aircraft in Australia, as they are a legislative instrument under section 6 of the Legislative Instruments Act 2003 and can be disallowed under section 46A of the Acts Interpretation Act 1901.
CASA, as the regulatory body responsible for civil aviation safety, has the authority and obligation to issue ADs to address safety concerns or discrepancies identified in aircraft or aeronautical products. These directives can mandate specific actions, such as inspections, repairs, or modifications, to ensure that the aircraft or products continue to meet the required safety standards. For instance, CASA issued AD/L.40/5 for the Meta Sokol L.40 aircraft, which was subsequently cancelled due to changes in the aircraft's status and international obligations under the Convention on International Civil Aviation. The cancellation of AD/L.40/5, effective from 27 August 2009, signifies that no further action is required under this particular directive.
Under the Convention on International Civil Aviation, the State of Design holds the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. CASA, acting as the State of Registry, must ensure that the aircraft under its purview comply with the ADs issued. The cancellation of AD/L.40/5 was in line with Australia's obligations under this international convention, and no public consultation was required as ADs generally do not necessitate a Regulatory Impact Statement.
Breaching the requirements set out in an AD can have significant legal consequences. Under the Civil Aviation Act 1988, operators and owners of aircraft are legally obligated to comply with ADs. Failure to do so can result in civil penalties, including fines and potential legal action by CASA. Additionally, non-compliance with ADs can lead to the grounding of an aircraft, which can have severe operational and financial implications for the operator. The specific penalties for non-compliance are detailed in the Civil Aviation Act 1988 and may include fines up to a certain amount, reflecting the seriousness of maintaining airworthiness standards.
