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/RAD/29 affecting Sunair HF Transceivers ASB-100 and 100A. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/29. 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 was enacted to establish the framework for the regulation of civil aviation in Australia and ensure the safety of air navigation. The Act empowers the Governor-General to make regulations that support the overarching objective of aviation safety. In accordance with section 98 of the Civil Aviation Act 1988, the Civil Aviation Safety Regulations 1998 were subsequently introduced to provide further detail on operational and safety requirements. Under these regulations, the Civil Aviation Safety Authority (CASA) is authorised to issue airworthiness directives for specific types of aircraft or aeronautical products. This legislative framework ensures that CASA, as Australia's national airworthiness authority, can effectively implement international safety standards and maintain the continuing airworthiness of aircraft registered in Australia. The authority to issue these directives is rooted in the responsibilities outlined in Annex 8 of the Convention on International Civil Aviation, where the State of Design holds overall responsibility for the continuing airworthiness of aircraft types.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together provide the framework for issuing airworthiness directives (ADs) in Australia, with the Civil Aviation Safety Authority (CASA) having the authority to issue these directives under regulation 39.001. These regulations apply to all aircraft and aeronautical products on the Australian Register, ensuring the continuing airworthiness of these items in accordance with the Convention on International Civil Aviation. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and when it issues an AD, CASA, as Australia’s national airworthiness authority, is obligated to assess the information and issue a corresponding Australian AD if necessary. The ADs are legislative instruments under the Legislative Instruments Act 2003 and must be assessed for compliance with international obligations. The State of Registry, in this case CASA, is tasked with ensuring that the aircraft meets all required safety standards, and any cancellation of an AD, such as AD/RAD/29 concerning Sunair HF Transceivers ASB-100 and 100A, is made to reflect changes in safety conditions or international obligations, without necessitating public consultation or a Regulatory Impact Statement. The ADs are issued by CASA on behalf of the Governor-General, ensuring they align with the overarching goals of the Civil Aviation Act 1988 and the safety mandates set by international aviation standards.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under regulation 39.001, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products (39.001). These ADs are instrumental in ensuring the continuing safety and airworthiness of aircraft. In line with section 98 of the Civil Aviation Act 1988, CASA's authority to issue these directives is grounded in the overarching objective of enhancing air navigation safety (98). Furthermore, subregulation 39.001(5) classifies ADs as disallowable instruments, and thus, they are recognised as legislative instruments under the Legislative Instruments Act 2003 (39.001(5)).
Entities governed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, particularly aircraft manufacturers, operators, and regulatory bodies, bear specific obligations. The State of Design has the primary responsibility for the continuing airworthiness of an aircraft type, and must provide necessary information to ensure the safety of the aircraft type to the States of Registry (Annex 8). The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of individual aircraft registered within its jurisdiction. When an AD is issued by a State of Design for a type of aircraft registered in Australia, CASA must review the directive and, if necessary, issue a corresponding Australian AD to enforce the required safety measures (Annex 8).
Failure to comply with ADs may result in significant legal consequences. Regulatory breaches can lead to both civil and criminal penalties, depending on the nature and severity of the non-compliance. The specific penalties are outlined in relevant sections of the Civil Aviation Act 1988 and associated regulations, but may include fines, imprisonment, or both. It is essential for all parties involved, such as aircraft manufacturers and operators, to adhere strictly to the directives issued to ensure compliance with safety standards.
In summary, under the Civil Aviation Safety Regulations 1998, CASA has the authority to issue ADs to maintain the airworthiness of aircraft. The State of Design and the State of Registry have specific responsibilities to ensure aircraft safety, and CASA must enforce these directives within Australia. Non-compliance with these directives can result in substantial legal repercussions, emphasising the importance of adhering to the regulations to maintain the highest safety standards in air navigation.
