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 US FAA has issued AD 2008-14-13 affecting Cirrus SR20 and SR22 model aircraft. The USA is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/CIRRUS/11, which will become effective on 28 August 2008.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, is designed to provide a comprehensive legislative framework for civil aviation within Australia, ensuring safety and efficiency in air navigation. The Act empowers the Governor-General to create regulations, with a specific focus on enhancing air safety. One critical instrument within this legislative framework is the Civil Aviation Safety Regulations 1998, which allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft and aeronautical products. These ADs are essential for maintaining the continuing airworthiness of aircraft, as they mandate compliance with safety requirements established by the aircraft's State of Design. This mechanism ensures that Australia adheres to international standards set by the International Civil Aviation Organization (ICAO) and complies with obligations under the Convention on International Civil Aviation. The ADs are considered legislative instruments, subject to disallowance and review processes.
Scope and Application
The Civil Aviation Safety Regulations 1998 provide the framework for issuing airworthiness directives (ADs) under the Civil Aviation Act 1988, with the overarching goal of ensuring the safety of air navigation. These ADs apply to aircraft or aeronautical products specified by the Civil Aviation Safety Authority (CASA) and are mandated by the State of Design under the Convention on International Civil Aviation. Each State of Registry, including Australia, must ensure the continuing airworthiness of aircraft registered within its jurisdiction. When an AD is issued by a State of Design, CASA, as Australia's national airworthiness authority, is required to assess the directive and, if appropriate, issue an Australian AD. The ADs are legislative instruments and do not require public consultation or a Regulatory Impact Statement. The ADs are issued under the authority of the Manager, Airframes in the Airworthiness Engineering Branch, in accordance with the Act.
Key Provisions
The Civil Aviation Act 1988, specifically under section 98, empowers the Governor-General to establish regulations aimed at ensuring the safety of air navigation. Within this framework, the Civil Aviation Safety Regulations 1998, under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. An AD is a disallowable instrument as per section 46A of the Acts Interpretation Act 1901, and it is considered a legislative instrument under section 6 of the Legislative Instruments Act 2003. These directives play a crucial role in maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 of the Convention on International Civil Aviation, which places the responsibility on the State of Design to provide necessary information to ensure an aircraft type’s airworthiness.
The obligations imposed by these regulations necessitate that the State of Design, such as the United States in the case of Cirrus SR20 and SR22 model aircraft, issues ADs to address identified safety concerns. CASA, as Australia’s national airworthiness authority, must evaluate these directives and, if appropriate, issue corresponding Australian ADs to enforce the requirements on the Australian Register. The State of Registry, in this case, Australia, must then ensure the continuing airworthiness of the affected aircraft by adhering to the issued ADs. This process underscores the importance of international collaboration in maintaining aviation safety standards and ensuring that all relevant parties are informed and compliant with the necessary regulatory requirements.
Failure to comply with the ADs can result in serious safety risks and potential legal consequences. While the specific penalties for non-compliance with ADs are not detailed within the provided text, general aviation regulations typically include both civil and criminal penalties for violations. Civil penalties may include fines, while criminal penalties can range from imprisonment to more severe consequences depending on the severity of the breach and the impact on aviation safety. The stringent nature of these regulations highlights the critical importance of adhering to ADs to maintain the high safety standards required in the aviation industry.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a structured approach to issuing and enforcing airworthiness directives, ensuring that all stakeholders, particularly the States of Design and Registry, work collaboratively to maintain the safety and airworthiness of aircraft. The obligations placed on CASA and the State of Registry are essential to upholding international aviation safety standards and protecting the public from potential risks associated with non-compliance.
