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/ROBIN/10 Amendment 1 affecting all models of Robin Aviation R2000 series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/ROBIN/10 Amendment 1. The cancellation will become effective on 2 July 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, Airframe and Structures, 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 comprehensive framework for the regulation of civil aviation within Australia, addressing the need for safety standards and regulatory oversight to ensure the safe and efficient operation of aircraft. The Civil Aviation Safety Regulations 1998, made under section 98 of the Act, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, thereby facilitating the enforcement of continuing airworthiness requirements. The Civil Aviation Safety Regulations 1998 also designate ADs as disallowable instruments under the Acts Interpretation Act 1901, underscoring their legislative status. In accordance with Annex 8 to the Convention on International Civil Aviation, the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for ensuring the continuing airworthiness of individual aircraft. Consequently, CASA must evaluate and, if necessary, issue Australian ADs to mandate the requirements of foreign ADs issued by States of Design for aircraft registered in Australia. The text indicates that ADs do not necessitate a Regulatory Impact Statement, and the Office of Best Practice Regulation has determined that they do not require public consultation, as they pertain to technical safety measures rather than broader policy changes.
Scope and Application
The Civil Aviation Act 1988, as supplemented by the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) which are legislative instruments intended to ensure the safety of air navigation. These regulations apply to all kinds of aircraft and aeronautical products, and are issued under the authority of the Governor-General as part of broader safety measures. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 mandates that CASA can issue ADs to maintain the airworthiness of aircraft. The ADs are subject to disallowance under the Acts Interpretation Act 1901, and must comply with the Legislative Instruments Act 2003. The application of these directives is consistent with international standards set by Annex 8 to the Convention on International Civil Aviation, which outlines the responsibilities of the State of Design and the State of Registry in ensuring aircraft airworthiness. The scope of these regulations is national, applying to all aircraft registered in Australia, and CASA is responsible for assessing and issuing ADs based on international standards. The ADs may be cancelled if the unsafe conditions they were designed to address no longer exist, without the need for public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the framework for the regulation of airworthiness directives (ADs) in Australia, as per section 98 (authorising the Governor-General to make regulations for the safety of air navigation) and regulation 39.001 (authorising the Civil Aviation Safety Authority, CASA, to issue ADs for aircraft or aeronautical products). These ADs, as specified in subregulation 39.001(5), are legislative instruments subject to disallowance under the Acts Interpretation Act 1901 and are governed by the Legislative Instruments Act 2003. Annex 8 to the Convention on International Civil Aviation assigns the State of Design the responsibility for ensuring the continuing airworthiness of an aircraft type and mandates the provision of necessary information to the States of Registry. The State of Registry, in turn, is responsible for ensuring the continuing airworthiness of individual aircraft and must develop or adopt requirements to achieve this, as per Annex 8. In cases where a State of Design issues an AD for a type of aircraft registered in Australia, CASA must evaluate the information and, if deemed appropriate, issue an Australian AD to enforce the State of Design's requirements.
Entities governed by these regulations, such as aircraft operators, manufacturers, and maintenance providers, must comply with the requirements set out in the ADs issued by CASA. This includes adhering to any specified maintenance actions, inspections, or operational limitations to ensure the continued airworthiness of their aircraft. Failure to comply with an AD can result in serious safety risks and potential legal consequences.
The Civil Aviation Safety Regulations 1998 do not explicitly outline offences or penalties for non-compliance with ADs, but non-compliance can lead to serious civil and criminal consequences under the Civil Aviation Act 1988. For instance, section 48 of the Act allows CASA to take enforcement actions against entities that fail to comply with regulations, including issuing fines or prosecuting individuals and corporations for violations. The maximum penalties for offences under the Civil Aviation Act can be significant, reflecting the importance of adhering to airworthiness directives for the safety of air navigation.
