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.
Transport Canada has issued AD CF-88-18 affecting Eurocopter Canada BO 105 model helicopters. Canada is the State of Design for some BO 105s. CASA has assessed this AD and has issued Australian AD/BO 105/23, which will become effective on 27 September 2007.
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, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988 was enacted to provide a comprehensive framework for the regulation of civil aviation in Australia, addressing the need for a cohesive legal structure to govern the industry. This Act empowers the Governor-General to make regulations, such as the Civil Aviation Safety Regulations 1998, for ensuring the safety of air navigation. Under this legislative scheme, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) to maintain the continuing airworthiness of aircraft registered in Australia. ADs are a key regulatory tool mandated by international standards, specifically under Annex 8 to the Convention on International Civil Aviation, and are instrumental in ensuring that aircraft types meet necessary safety requirements. CASA, as Australia’s national airworthiness authority, is responsible for issuing these directives in alignment with international obligations and to safeguard the safety of Australian-registered aircraft. This legislative framework aims to uphold the highest safety standards in civil aviation, ensuring that all aircraft meet the necessary regulatory requirements both domestically and internationally.
Scope and Application
The Civil Aviation Safety Regulations 1998, as amended and under the authority of the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) that apply to specific types of aircraft or aeronautical products within Australia. These ADs are legislative instruments that aim to ensure the safety of air navigation and are issued in accordance with international standards set by the International Civil Aviation Organization (ICAO). The ADs apply to aircraft registered in Australia, and CASA, acting as the national airworthiness authority, is responsible for assessing and implementing the directives issued by the relevant State of Design. This ensures that the continuing airworthiness of aircraft is maintained in line with international obligations. Notably, these directives are issued without public consultation and do not require a Regulatory Impact Statement, as determined by the Office of Best Practice Regulation. The ADs are applicable nationwide and extend to all aircraft and aeronautical products subject to the regulations, with the specific details and enforcement mechanisms detailed in the subordinate regulations and international conventions.
Key Provisions
The Civil Aviation Act 1988, along with the Civil Aviation Safety Regulations 1998, provides the legal framework for the issuance and enforcement of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). Under section 98 of the Act, the Governor-General is empowered to create regulations for the safety of air navigation, and regulation 39.001 specifically authorises CASA to issue ADs for types of aircraft or aeronautical products. These directives are legislative instruments under the Acts Interpretation Act 1901, which means they must comply with the Legislative Instruments Act 2003.
The obligations imposed by these regulations require CASA to assess and, where appropriate, mandate the requirements of ADs issued by the State of Design, ensuring the continuing airworthiness of aircraft types registered in Australia. The State of Design, which is responsible for the type-specific airworthiness, must provide necessary information to the State of Registry, which is obligated to implement and enforce these airworthiness measures. The State of Registry must also develop or adopt requirements to ensure that aircraft remain airworthy. For instance, when Transport Canada issued AD CF-88-18 for Eurocopter Canada BO 105 helicopters, CASA assessed this directive and issued Australian AD/BO 105/23, reflecting Australia's obligations under the Convention on International Civil Aviation.
There are no public consultation requirements for these ADs, as they are issued in response to international obligations and the directives of the State of Design. Additionally, the Office of Best Practice Regulation has determined that ADs do not necessitate a Regulatory Impact Statement. The Manager, Airframes in the Airworthiness Engineering Branch, acting on behalf of CASA, made this AD in accordance with subsection 84A(2) of the Act.
Failing to comply with an airworthiness directive can result in serious consequences. Under section 36(1) of the Civil Aviation Act 1988, a person who contravenes an AD can be liable to a civil penalty of up to $222,200 for individuals or $1,111,000 for corporations. Furthermore, under section 36(3) of the Act, the operation of an aircraft in contravention of an AD constitutes an offence. The maximum penalty for such an offence is $444,400 for an individual or $2,222,000 for a corporation, as stipulated in section 36(4). These penalties underscore the importance of adhering to ADs to maintain aviation safety standards.
