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/3 affecting all DR400 models of Robin Aviation series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/ROBIN/3. 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 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 to regulate the safety of air navigation, was instrumental in addressing the need for consistent and enforceable safety standards in civil aviation. The Act empowers the Governor-General to make regulations for the purposes of the Act, with a particular focus on ensuring the safety of air navigation. One significant aspect of this legislation is the ability of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as legislative instruments and are crucial for maintaining the continuing airworthiness of aircraft, as stipulated by Annex 8 of the Convention on International Civil Aviation. The process ensures that both the State of Design and the State of Registry collaborate to address any unsafe conditions that may affect the airworthiness of aircraft.
The Civil Aviation Safety Regulations 1998 were amended to facilitate the issuance of ADs, which are considered disallowable instruments under the Acts Interpretation Act 1901. This legislative framework allows CASA to issue ADs to mandate safety requirements based on assessments of information from the State of Design. The cancellation of Australian AD/ROBIN/3 affecting DR400 models of Robin Aviation series aeroplanes exemplifies the application of these regulations. CASA, as Australia's national airworthiness authority, assessed the AD and determined that it could be cancelled as the unsafe condition no longer existed, thereby ensuring compliance with Australia's obligations under the Convention on International Civil Aviation. The decision to cancel the AD was made by the Systems and New Technologies in the Airworthiness Engineering Group on behalf of CASA, in accordance with subsection 84A(2) of the Act.
Scope and Application
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, provides the framework for ensuring the safety of air navigation in Australia. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for types of aircraft or aeronautical products, which are legislative instruments as per the Acts Interpretation Act 1901. This process is critical in maintaining the continuing airworthiness of aircraft registered in Australia. The ADs are issued in accordance with the Convention on International Civil Aviation, where the State of Design holds the responsibility for ensuring the airworthiness of an aircraft type, while the State of Registry must implement the necessary requirements. CASA, as Australia’s national airworthiness authority, assesses information provided by the State of Design and, if necessary, issues corresponding Australian ADs. For instance, AD/ROBIN/3, which affected all DR400 models of Robin Aviation series aeroplanes, was cancelled by CASA on 2 July 2009, as the unsafe condition no longer existed, and no further ADs were required. The cancellation aligns with Australia’s international obligations and did not necessitate public consultation or a Regulatory Impact Statement.
Key Provisions
The main operative sections of the Civil Aviation Act 1988, particularly section 98, empower the Governor-General to establish regulations that serve the interests of air navigation safety. Within this framework, 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 are intended to ensure the continuing airworthiness of aircraft, as mandated by international standards such as Annex 8 to the Convention on International Civil Aviation. In particular, subregulation 39.001(5) specifies that ADs are disallowable instruments, meaning they are subject to parliamentary scrutiny under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 primarily rest on CASA and the State of Registry. CASA, as Australia's national airworthiness authority, is responsible for assessing ADs issued by the State of Design and, if necessary, issuing Australian ADs to mandate the requirements. The State of Registry must ensure the continuing airworthiness of individual aircraft, developing or adopting the necessary requirements to achieve this. These requirements are typically communicated through ADs issued by the State of Design, which CASA must then review and implement if appropriate. The State of Design, meanwhile, has the overarching responsibility of providing necessary information to ensure the airworthiness of aircraft types.
The Civil Aviation Act 1988 and Civil Aviation Safety Regulations 1998 do not explicitly outline specific offences, penalties, or consequences for breaches within the context of airworthiness directives. However, the overarching legal framework of Australian administrative law applies. Under this framework, breaches of regulations can lead to administrative penalties, including fines, and in severe cases, the revocation of certificates of airworthiness, which can result in the grounding of affected aircraft. While the specific penalties are not detailed within the AD cancellation notice itself, the broader legal context suggests that non-compliance with ADs could lead to significant administrative and legal repercussions for the parties involved.
Given the critical nature of airworthiness directives, the procedural steps taken in the cancellation of AD/ROBIN/3 highlight the stringent oversight and adherence to international standards. The cancellation of this particular AD, effective from 2 July 2009, reflects CASA's commitment to ensuring that no unsafe conditions persist on aircraft registered in Australia. The decision to cancel the AD without public consultation underscores the importance of international obligations and the internal processes within CASA. Furthermore, the Office of Best Practice Regulation's determination that ADs do not require a Regulatory Impact Statement indicates the streamlined yet rigorous approach taken in managing airworthiness directives.
