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/13 Amendment 1 affecting Rexair VTR-5 series VHF Transceivers. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/13 Amendment 1. 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 Parliament of Australia, was designed to ensure the safety and efficiency of civil aviation within the country. One of the key mechanisms introduced by this Act to maintain airworthiness standards is the issuance of airworthiness directives (ADs) under regulation 39.001 of the Civil Aviation Safety Regulations 1998. These ADs serve as legislative instruments aimed at addressing specific safety issues identified in aircraft types or aeronautical products. The Civil Aviation Safety Authority (CASA) has the authority to issue these directives, which must be aligned with Australia's obligations under the Convention on International Civil Aviation. This approach ensures that continuing airworthiness requirements are effectively communicated and enforced, maintaining high safety standards within the civil aviation sector.
Scope and Application
The Civil Aviation Act 1988 and associated Civil Aviation Safety Regulations 1998 empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) concerning specific types of aircraft or aeronautical products, under regulation 39.001. These directives are legislative instruments that must be assessed and, if appropriate, adopted by CASA to ensure the continuing airworthiness of aircraft registered in Australia. Such directives apply to the aircraft and aeronautical products within the Australian jurisdiction, and CASA's authority in this area is derived from international obligations under Annex 8 of the Convention on International Civil Aviation. This framework ensures that ADs issued by the State of Design are properly evaluated and, if necessary, translated into Australian regulations to maintain safety standards. Additionally, the cancellation of an AD, such as AD/RAD/13 Amendment 1 affecting Rexair VTR-5 series VHF Transceivers, is determined by CASA and reflects Australia’s adherence to international safety protocols, without necessitating public consultation or a Regulatory Impact Statement.
Key Provisions
The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, establishes the framework for airworthiness directives (ADs) as stipulated under section 98 of the Act and regulation 39.001 of the Regulations (39.001(5)). These ADs serve as critical instruments for ensuring the safety of air navigation by specifying mandatory requirements for aircraft and aeronautical products. As a legislative instrument, an AD is subject to disallowance under section 46A of the Acts Interpretation Act 1901 and is governed by the Legislative Instruments Act 2003.
Under these provisions, the Civil Aviation Safety Authority (CASA) is tasked with issuing ADs to mandate safety requirements for aircraft and aeronautical products on the Australian Register. This obligation stems from the responsibilities of the State of Design, as outlined in Annex 8 to the Convention on International Civil Aviation, which places the onus on the designing State to provide information necessary for maintaining airworthiness. The State of Registry, in this case CASA, must assess this information and, if deemed necessary, issue corresponding ADs to ensure compliance with safety standards.
Entities governed by these regulations, primarily aircraft operators and manufacturers, must adhere to the requirements specified in the ADs. This includes conducting inspections, making repairs, or implementing modifications as stipulated in the directives. Failure to comply with an AD can result in serious safety risks, and hence, it is imperative for these entities to promptly address the requirements to maintain the airworthiness of their aircraft.
Non-compliance with an airworthiness directive can lead to significant consequences. Civil penalties may be imposed, with maximum penalties outlined in the Civil Aviation Act 1988. Additionally, criminal penalties may apply for more severe breaches, including fines and imprisonment. The authority to enforce these penalties rests with CASA, which can take appropriate action against entities that fail to comply with ADs, thereby ensuring the highest standards of safety in air navigation.
