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/RUTAN/1 affecting all models of RUTAN Varieze series aeroplanes. CASA has assessed this AD and as a result has cancelled Australian AD/RUTAN/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 establish a legislative framework that ensures the safety and efficiency of civil aviation in Australia. This Act provides the authority for the Civil Aviation Safety Regulations 1998, which among other things, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs). These ADs are critical for maintaining the continuing airworthiness of aircraft and aeronautical products, thereby ensuring public safety. The ADs serve as a regulatory tool to address safety concerns, often in response to directives issued by the State of Design under international agreements such as Annex 8 to the Convention on International Civil Aviation. The authority to issue these ADs is exercised by CASA, which acts as Australia's national airworthiness authority, aligning with international obligations and domestic safety standards. The process of issuing and cancelling ADs, as seen in the case of the RUTAN Varieze series aeroplanes, reflects the dynamic nature of aviation safety regulation and the need to respond promptly to emerging safety issues.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a comprehensive framework for ensuring the safety of air navigation in Australia. Under section 98 of the Civil Aviation Act 1988, the Governor-General has the power to make regulations that serve the interests of safety in air navigation. The Civil Aviation Safety Regulations 1998 further delegate this power to the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments that hold significant authority in maintaining the airworthiness of aircraft registered in Australia. Geographically, these regulations apply nationally within Australia, aligning with international obligations under the Convention on International Civil Aviation. The State of Design is responsible for the continuing airworthiness of an aircraft type, while the State of Registry, in this case CASA, ensures these standards are upheld for individual aircraft. ADs serve as critical tools for communicating necessary safety measures, and their issuance or cancellation reflects Australia's commitment to international aviation safety standards.
Key Provisions
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives serve as legislative instruments (section 46A of the Acts Interpretation Act 1901) that must be aligned with international standards as per Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the initial design of the aircraft, has a duty to provide necessary information to ensure the aircraft's continuing airworthiness, a responsibility that is further upheld by the State of Registry of the individual aircraft.
In practical terms, if a State of Design issues an AD for an aircraft type registered in Australia, CASA must evaluate the directive and, if deemed necessary, issue an Australian AD to enforce the requirements set by the State of Design. For instance, CASA has issued and subsequently cancelled Australian AD/RUTAN/1 for all models of RUTAN Varieze series aeroplanes. This cancellation, effective from 2 July 2009, was due to the resolution of the unsafe condition that originally prompted the directive. Given the international obligations under the Convention on International Civil Aviation, no public consultation was conducted for this AD cancellation, and it was deemed unnecessary to prepare a Regulatory Impact Statement by the Office of Best Practice Regulation.
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 must adhere to ADs as they are integral to maintaining the airworthiness of aircraft. CASA's role in issuing and cancelling these directives is crucial, ensuring that all aircraft registered in Australia meet the required safety standards. This process underscores the importance of international cooperation in aviation safety, where the State of Design and the State of Registry work together to protect public safety in air navigation.
Under the Civil Aviation Act 1988, failure to comply with an AD can lead to serious consequences. Operators of affected aircraft must ensure adherence to the mandated safety measures. Breaches can result in severe penalties, including fines and potential criminal charges. For instance, CASA can impose fines of up to $1,215,000 for corporations and $243,000 for individuals for non-compliance with ADs. Such stringent measures underscore the critical nature of adhering to airworthiness directives to maintain safety in air navigation.
