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/34 affecting Sunair HF Transceivers ASB-320. CASA has assessed this AD and as a result has cancelled Australian AD/RAD/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 Australian Parliament, serves as the foundational legislation governing civil aviation in Australia. The Act was introduced to establish a comprehensive legal framework for ensuring the safety and efficiency of civil aviation within the country. The Act empowers the Governor-General to create regulations that align with the Act's objectives, particularly focusing on the safety of air navigation. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, allow the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for various types of aircraft and aeronautical products. These directives are crucial for maintaining the continuing airworthiness of aircraft, a responsibility that falls on the State of Registry. In accordance with international obligations under the Convention on International Civil Aviation, Australia’s national airworthiness authority, CASA, assesses and, if necessary, issues Australian airworthiness directives based on information from the State of Design. The recent cancellation of Australian AD/RAD/34 concerning Sunair HF Transceivers ASB-320, due to the unsafe condition no longer existing, exemplifies CASA's role in fulfilling these obligations.
Scope and Application
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 together govern the issuance of airworthiness directives (ADs) in Australia, which are critical in maintaining the safety standards of aircraft and aeronautical products. Under the authority of the Civil Aviation Act 1988, the Governor-General has the power to make regulations for the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific kinds of aircraft or aeronautical products. These ADs are considered legislative instruments under the Legislative Instruments Act 2003. The State of Design is responsible for the continuing airworthiness of an aircraft type, and must provide necessary information to the State of Registry, which is tasked with ensuring the airworthiness of the individual aircraft. In Australia, CASA acts as the national airworthiness authority and must assess any ADs issued by the State of Design, issuing Australian ADs as necessary to mandate the requirements. The ADs are aligned with Annex 8 of the Convention on International Civil Aviation, which outlines the responsibilities of States regarding airworthiness.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, empowers the Governor-General to enact regulations that serve the safety of air navigation (sections 98, 39.001). The authority to issue airworthiness directives (ADs) is granted to the Civil Aviation Safety Authority (CASA) under these regulations. An AD is a legislative instrument that can be disallowed under the Acts Interpretation Act 1901 and is subject to the scrutiny of the Legislative Instruments Act 2003 (sections 46A, 6). ADs are crucial for maintaining the continuing airworthiness of aircraft and are issued by the State of Design, with the State of Registry responsible for ensuring the aircraft’s airworthiness on a more localised level.
The obligations under these provisions require CASA to act on ADs issued by the State of Design by assessing the information and determining if an Australian AD should be issued. This process ensures that Australian-registered aircraft meet the necessary safety standards as prescribed by international conventions. For example, CASA issued and subsequently cancelled Australian AD/RAD/34 concerning Sunair HF Transceivers ASB-320. This cancellation took effect on 9 April 2009, following the determination that the unsafe condition no longer existed. The State of Design’s obligations under the Convention on International Civil Aviation necessitate that CASA does not need to consult the Australian public or prepare a Regulatory Impact Statement for AD cancellations.
In terms of compliance, failure to adhere to ADs could lead to significant consequences. While the specific offences and penalties are not detailed in the provided text, non-compliance with airworthiness directives generally results in civil or criminal penalties. These could include fines, imprisonment, or other sanctions depending on the severity and intent of the breach. The precise penalties would be determined by the courts and would be in line with Australian law, ensuring that safety regulations are strictly enforced to maintain the integrity of the aviation safety framework.
