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/INST/34 affecting Honeywell SP-300 DFCS Mode Control Panels. CASA has assessed this AD and as a result has cancelled Australian AD/INST/34. The cancellation will become effective on 9 April 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, 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 by the Commonwealth Parliament, provides the legal framework for civil aviation in Australia, aiming to ensure safety and efficiency within the industry. As part of this legislation, the Civil Aviation Safety Regulations 1998 were established to detail the specific requirements and procedures to be followed to meet the overarching objectives of the Act. One of the key provisions of these regulations is the issuance of airworthiness directives (ADs), which are legislative instruments used to mandate compliance with safety standards for aircraft and aeronautical products. The Civil Aviation Safety Authority (CASA) has the authority to issue ADs in accordance with international standards, particularly those outlined in Annex 8 to the Convention on International Civil Aviation, ensuring that both the State of Design and the State of Registry uphold their responsibilities for the continuing airworthiness of aircraft. In instances where CASA determines that a previously issued AD is no longer necessary due to the resolution of a safety issue, it has the authority to cancel such an AD, as demonstrated by the cancellation of Australian AD/INST/34 concerning Honeywell SP-300 DFCS Mode Control Panels.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Safety Regulations 1998, establishes the framework for the regulation of civil aviation safety in Australia. Under this framework, the Civil Aviation Safety Authority (CASA) is empowered to issue airworthiness directives (ADs) for particular types of aircraft or aeronautical products, as stipulated in regulation 39.001 of the Civil Aviation Safety Regulations. These ADs serve as legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and are essential for maintaining the continuing airworthiness of aircraft as per Annex 8 of the Convention on International Civil Aviation. CASA’s role involves assessing airworthiness directives issued by the State of Design and determining the necessity to issue corresponding Australian ADs to ensure compliance with safety standards. The application of these regulations extends to all aircraft registered in Australia, encompassing both domestic and international operations, thus ensuring that all aircraft operating within Australia meet the necessary safety criteria.
Key Provisions
The Civil Aviation Safety Regulations 1998 (Regulations) allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) under regulation 39.001 to ensure the safety of air navigation, as per section 98 of the Civil Aviation Act 1988. This regulatory power is critical for maintaining the continuing airworthiness of aircraft types and individual aircraft. These directives, including their equivalents, are the most common form of continuing airworthiness information issued by most International Civil Aviation Organization (ICAO) Contracting States, as outlined in Annex 8 to the Convention on International Civil Aviation. Under this framework, the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, while the State of Registry is responsible for the airworthiness of individual aircraft. In Australia, CASA is mandated to assess any ADs issued by the State of Design and, if necessary, issue Australian ADs to enforce the State of Design's requirements.
The obligations imposed by the Civil Aviation Safety Regulations 1998 require CASA to meticulously assess any ADs issued by the State of Design concerning aircraft types on the Australian Register. This assessment ensures that CASA can adequately enforce the continuing airworthiness requirements for these aircraft. When CASA issues an Australian AD, it must comply with the legislative process outlined in the Legislative Instruments Act 2003, as ADs are considered disallowable instruments under the Acts Interpretation Act 1901. This compliance ensures that ADs are legally robust and enforceable within Australia's aviation regulatory framework. CASA’s role is further emphasized by its responsibility to cancel ADs, such as AD/INST/34 affecting Honeywell SP-300 DFCS Mode Control Panels, when the unsafe conditions they address are no longer present. This action aligns with Australia's obligations under the Convention on International Civil Aviation and reflects CASA’s commitment to maintaining the highest safety standards in aviation.
Breaches of the Civil Aviation Safety Regulations 1998, including non-compliance with ADs, can result in significant legal consequences. The Act and the Regulations outline various offences and penalties for violations, though specific maximum penalties are not detailed in this context. Violators may face civil or criminal penalties, depending on the nature and severity of the breach. For instance, non-compliance with an AD could lead to enforcement actions by CASA, including fines or other administrative penalties. In more severe cases, criminal charges could be brought, potentially resulting in imprisonment. These provisions underscore the importance of adhering to ADs and the regulatory framework established by CASA to ensure the safety of air navigation in Australia. The regulatory approach aims to prevent unsafe conditions from compromising the safety of aircraft and passengers.
