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/BEECH 90/81 affecting Beechcraft F90 model aircraft. CASA has assessed this AD and as a result has cancelled Australian AD/BEECH 90/81. The cancellation will become effective on 31 July 2008. 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, Systems and New Technologies, Manager, Airframe and Structures, 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, serves to regulate civil aviation and ensure safety in air navigation. Under this Act, the Civil Aviation Safety Regulations 1998 were made, allowing the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific aircraft types or aeronautical products to maintain safety standards. These ADs, as legislative instruments, play a crucial role in ensuring the continuing airworthiness of aircraft as stipulated by the Convention on International Civil Aviation. In line with Australia's obligations under this international convention, CASA has the responsibility to assess ADs issued by the State of Design and, if necessary, issue corresponding ADs for aircraft registered in Australia. This regulatory framework ensures that any unsafe conditions identified are addressed appropriately, maintaining the high safety standards expected in civil aviation.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 govern the issuance of airworthiness directives (ADs) in Australia, ensuring that the safety of air navigation is maintained. Under section 98 of the Act, the Governor-General has the authority to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance and review under the Legislative Instruments Act 2003. The ADs align with international standards as outlined in Annex 8 to the Convention on International Civil Aviation, where the State of Design holds the responsibility for the continuing airworthiness of aircraft types, and the State of Registry must ensure the continuing airworthiness of individual aircraft. CASA, as Australia’s national airworthiness authority, assesses information from the State of Design and, when necessary, issues corresponding Australian ADs. For example, CASA issued and subsequently cancelled AD/BEECH 90/81 for Beechcraft F90 model aircraft, effective from 31 July 2008, due to the resolution of the unsafe condition. This cancellation was made without public consultation, as determined by the Office of Best Practice Regulation, which also found that ADs do not require a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988 (sections 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) to ensure the safety of air navigation. ADs are regulatory instruments used to communicate safety-related information about aircraft, aeronautical products, or parts to ensure their continuing airworthiness. Under subregulation 39.001(5), an AD is considered a disallowable instrument, meaning it can be disallowed by either house of the Parliament, and it is classified as a legislative instrument under section 6 of the Legislative Instruments Act 2003. This legislative context underscores the regulatory authority and the procedural framework within which ADs are issued and managed.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 require CASA, as the national airworthiness authority, to assess airworthiness directives issued by the State of Design and to determine if they should be implemented in Australia. This involves evaluating the safety implications of the AD and deciding whether an Australian AD is necessary to mandate the requirements of the State of Design. Furthermore, the State of Registry is obligated to develop or adopt requirements to ensure the continuing airworthiness of aircraft, which includes complying with ADs. The State of Design, on the other hand, has the responsibility to provide necessary information to ensure the continuing airworthiness of an aircraft type, as stipulated under Annex 8 to the Convention on International Civil Aviation.
Failure to comply with the requirements set out in an AD may result in civil or criminal consequences. While the specific penalties are not detailed in the provided text, it is understood that non-compliance with ADs can lead to enforcement actions by CASA, including fines or other regulatory sanctions. The seriousness of such consequences underscores the importance of adhering to airworthiness directives to maintain the safety standards required by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. CASA’s authority to issue and enforce ADs is vital in maintaining the high safety standards expected in the aviation industry.
In summary, the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 empower CASA to issue ADs to ensure the safety of air navigation. The obligations on CASA, the State of Registry, and the State of Design are clear and defined, with a strong emphasis on the continuing airworthiness of aircraft. Non-compliance with these directives can result in significant consequences, reflecting the critical nature of safety in civil aviation. The legislative and regulatory framework ensures that all parties involved in aircraft operations are held to stringent safety standards.
