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/R22/27 affecting Robinson R22 helicopters. CASA has reviewed this AD and as a result has cancelled it. The cancellation will become effective on 7 May 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, Airframes 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 ensure the safety and efficiency of civil aviation in Australia, establishing a regulatory framework overseen by the Civil Aviation Safety Authority (CASA). In this context, the Civil Aviation Safety Regulations 1998 were also introduced to provide further detail on the operational and safety standards that must be adhered to. One of the critical mechanisms within this framework is the issuance of airworthiness directives (ADs) by CASA, as authorised under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These directives, which are legislative instruments, are intended to address any safety issues that may arise with aircraft or aeronautical products, thereby ensuring the continuing airworthiness of aircraft registered in Australia. The cancellation of a specific AD affecting Robinson R22 helicopters, as detailed in the explanatory statement, was made in accordance with Australia’s obligations under the Convention on International Civil Aviation, which mandates that the State of Design must provide necessary information for the continuing airworthiness of an aircraft type to the States of Registry. This process does not require public consultation or a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, provides a framework for the regulation of civil aviation activities in Australia. Under this legislative regime, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs), which are regulatory instruments aimed at ensuring the safety of aircraft and aeronautical products. These directives are issued in accordance with Annex 8 of the Convention on International Civil Aviation, reflecting Australia’s commitment to international aviation safety standards. The ADs apply to the State of Registry of the aircraft, which is responsible for ensuring the continuing airworthiness of the aircraft in accordance with international and domestic regulations. The ADs serve as a critical mechanism for communicating safety-related information and requirements to aircraft owners and operators. The scope of the ADs is broad, encompassing various types of aircraft and aeronautical products, and they are subject to the disallowance provisions under the Acts Interpretation Act 1901, with their status as legislative instruments affirmed under the Legislative Instruments Act 2003. The application of these directives is subject to the oversight and enforcement mechanisms provided by CASA, reflecting the high priority given to aviation safety in Australia.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together establish the framework for ensuring the safety and airworthiness of aircraft in Australia. Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations necessary for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 grants the Civil Aviation Safety Authority (CASA) the power to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are considered legislative instruments under the Legislative Instruments Act 2003. Airworthiness directives are a crucial component of maintaining the continuing airworthiness of aircraft, as mandated by Annex 8 to the Convention on International Civil Aviation. This convention places the responsibility for the continuing airworthiness of an aircraft type on the State of Design and requires it to provide necessary information to the State of Registry.
Under the Civil Aviation Safety Regulations 1998, CASA is empowered to issue ADs that specify requirements and actions to address safety issues identified in specific aircraft types or aeronautical products. This regulatory approach ensures that all stakeholders, including aircraft operators and maintenance providers, are aware of and comply with necessary safety measures. For instance, CASA or its predecessors issued AD/R22/27 concerning Robinson R22 helicopters. However, after a review, CASA has decided to cancel this particular AD, effective from 7 May 2009. The cancellation is due to Australia's obligations under the Convention on International Civil Aviation, which does not necessitate public consultation on such AD cancellations. Additionally, the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement.
The obligations imposed by these regulations are primarily on aircraft operators and maintenance providers. They must comply with the ADs issued by CASA, which may include conducting specific inspections, repairs, or modifications to ensure the aircraft remains airworthy. Failure to comply with an AD can lead to significant safety risks, potentially resulting in aircraft being grounded or prohibited from flying. CASA closely monitors compliance with ADs to ensure that all aircraft meet the required safety standards.
Failure to comply with an airworthiness directive can result in severe penalties. Under section 31 of the Civil Aviation Act 1988, any person who contravenes an AD can be subject to a civil penalty of up to $222,200 for individuals and $1,111,000 for bodies corporate. Additionally, CASA can issue infringement notices for breaches of the Civil Aviation Safety Regulations 1998, with penalties ranging up to $5,555 for individuals and $27,770 for bodies corporate. Criminal penalties can also apply for more serious breaches, including imprisonment for up to two years. These stringent measures underscore the importance of adhering to ADs to maintain the highest safety standards in aviation.
