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/8 affecting AWA VHF NAV/COM Receiver Type AD704. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/8. 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 to regulate civil aviation in Australia and ensure the safety of air navigation, empowers the Governor-General to create regulations that serve these objectives. In accordance with regulation 39.001 of the Civil Aviation Safety Regulations 1998, the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. This regulatory framework is designed to maintain the continuing airworthiness of aircraft in alignment with international standards, particularly those set by the International Civil Aviation Organization (ICAO). The Civil Aviation Act 1988 and associated regulations mandate that CASA, as the national airworthiness authority, assess and respond to ADs issued by the State of Design, ensuring that Australian registered aircraft meet necessary safety standards. The enactment of these regulations and the issuance of ADs reflect a commitment to maintaining the highest safety standards in Australian civil aviation, as part of the broader commitment to international aviation safety protocols.
Scope and Application
The Civil Aviation Act 1988 applies to any person or entity involved in the operation of aircraft and aeronautical products in Australia. Specifically, the Act empowers the Governor-General to make regulations concerning the safety of air navigation, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Safety Regulations 1998. ADs are legislative instruments that mandate specific safety measures for particular types of aircraft or aeronautical products to ensure their continuing airworthiness. This regulation extends nationally across Australia and adheres to international standards set by the Convention on International Civil Aviation, particularly Annex 8, which outlines the responsibility of the State of Design and the State of Registry for ensuring aircraft airworthiness. The AD cancellation in this instance, affecting AWA VHF NAV/COM Receiver Type AD704, was made without public consultation and does not require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The AD was issued by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in compliance with the Act.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 establish a framework for ensuring the safety of air navigation and the continuing airworthiness of aircraft. Section 98 of the Act allows the Governor-General to make regulations to ensure air navigation safety, and regulation 39.001 specifically empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain aircraft or aeronautical products. These ADs are legislative instruments that mandate safety requirements and are subject to disallowance under section 46A of the Acts Interpretation Act 1901.
The obligations imposed by the Act and the Regulations include a responsibility on the State of Design to ensure the continuing airworthiness of aircraft types and provide necessary information to the States of Registry. The State of Registry, in turn, must develop or adopt requirements to maintain the airworthiness of aircraft registered within its jurisdiction. When an AD is issued by the State of Design, CASA must assess the information and, if necessary, issue an Australian AD to enforce the requirements for aircraft registered in Australia.
Failure to comply with ADs can lead to serious consequences. Although the specific penalties for non-compliance are not detailed in the text, non-compliance with safety regulations generally can result in civil or criminal penalties under the Civil Aviation Act 1988. These penalties can include fines and, in severe cases, imprisonment. The text does not specify the exact penalties but indicates that adherence to ADs is crucial for maintaining aviation safety.
The text also notes that, in this instance, the cancellation of AD/RAD/8 was due to Australia's obligations under the Convention on International Civil Aviation, and no consultation with the Australian public was required. Furthermore, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The AD was 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, ensuring that the process complies with legislative requirements.
