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 European Aviation Safety Authority (EASA) has issued AD 2006-0334R1 affecting data communication radios manufactured by Thales Communications. The EASA acts on behalf of France, the State of Design for this equipment. CASA has assessed this AD and has issued Australian AD/RAD/87, Amendment 1, which will become effective on 7 May 2009. This AD cancels and replaces the previous issue.
As this AD is issued because of Australia’s obligations under Convention on International Civil Aviation, and because it is issued in response to an AD raised by the relevant State of Design, no consultation of the Australian public has taken place on this AD. 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 provide a legislative framework for the regulation of civil aviation in Australia, ensuring safety and efficiency in air navigation. One of the mechanisms introduced under this Act is the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). This legislative instrument aims to maintain and ensure the continuing airworthiness of aircraft and aeronautical products in accordance with international standards set by the Convention on International Civil Aviation. The Civil Aviation Safety Regulations 1998 further detail the process by which CASA can issue ADs, which are considered disallowable instruments under the Acts Interpretation Act 1901. These directives serve as critical tools for CASA to mandate safety requirements and ensure compliance with international obligations, particularly in response to ADs issued by the State of Design. This approach facilitates harmonised safety standards across ICAO Contracting States, enhancing global aviation safety.
Scope and Application
The Civil Aviation Act 1988, specifically under regulation 39.001 of the Civil Aviation Safety Regulations 1998, empowers the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, with these directives being considered legislative instruments. These ADs are integral to ensuring the continuing airworthiness of aircraft, a responsibility assigned to the State of Registry under Annex 8 to the Convention on International Civil Aviation. The Civil Aviation Act 1988 extends its reach to all aircraft registered in Australia and to any aeronautical products used in aviation within Australia, thereby impacting the aircraft industry and all entities involved in the maintenance and operation of aircraft. The application of ADs is dictated by international obligations and is tailored to specific types of aircraft or aeronautical products as identified by the relevant State of Design. Notably, this legislation does not mandate consultation with the public or require a Regulatory Impact Statement for ADs, as determined by the Office of Best Practice Regulation. This streamlined process ensures that ADs can be issued swiftly in response to international safety directives without unnecessary bureaucratic delays.
Key Provisions
The main operative sections of this legislation concern the issuance and application of airworthiness directives (ADs). Section 98 of the Civil Aviation Act 1988 allows the Governor-General to make regulations in the interests of air navigation safety, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. Subregulation 39.001(5) further clarifies that an AD is a disallowable instrument under the Acts Interpretation Act 1901, and thus a legislative instrument according to the Legislative Instruments Act 2003.
The obligations imposed by these provisions require CASA to assess ADs issued by the State of Design and, where appropriate, issue corresponding Australian ADs to mandate the required safety measures. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to ensure compliance with international standards, as outlined in Annex 8 to the Convention on International Civil Aviation. The State of Registry, on the other hand, is tasked with developing or adopting requirements to ensure the continuing airworthiness of aircraft on its register. This includes implementing the ADs issued by CASA in response to those from the State of Design.
In terms of consequences for non-compliance, although specific offences and penalties are not detailed within the text, breaches of ADs could lead to serious safety risks, potentially resulting in civil or criminal liability under other provisions of the Civil Aviation Act 1988. Given the stringent nature of aviation safety regulations, non-compliance could result in severe penalties, including fines and imprisonment, depending on the severity of the breach and its impact on air safety. The overarching intent of these provisions is to ensure that all parties involved in the maintenance and operation of aircraft adhere to stringent safety standards to protect public safety and comply with international aviation regulations.
