CIVIL AVIATION ACT 1988
CIVIL AVIATION 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. An AD is a disallowable instrument under section 46A of the Acts Interpretation Act 1901.
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 US FAA has issued AD 2004-24-09 affecting Rolls Royce Corporation 250-B and 250-C series turboshaft engines. The US is the State of Design for these types. CASA has assessed this AD and has issued Australian AD/AL 250/85, which will become effective on 17 March 2005.
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 Regulatory Review has determined that ADs do not require a Regulatory Impact Statement.
The AD has been made by the Section Head - Systems, Airworthiness Standards Branch, Standards Division, on behalf of CASA, in accordance with subsection 84A (2) of the Act.
Overview
The Civil Aviation Act 1988, enacted by the Australian Parliament, addresses the need for regulations governing the safety of air navigation, with a particular focus on the issuance of airworthiness directives to ensure the safety and continuing airworthiness of aircraft within Australia. The Act empowers the Governor-General to make regulations in the interests of safety, and section 98 of the Act facilitates the creation of these regulations. The Civil Aviation Safety Regulations 1998 further empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, which are instrumental in maintaining safety standards as outlined by the International Civil Aviation Organization (ICAO). This legislative framework is essential for Australia to fulfil its international obligations under the Convention on International Civil Aviation, particularly those concerning the State of Design's responsibility for providing continuing airworthiness information and the State of Registry's duty to enforce these standards domestically. The policy objective is to ensure that Australian aviation remains safe and compliant with international standards, thereby safeguarding public safety and maintaining Australia's reputation in global aviation.
Scope and Application
The Civil Aviation Act 1988, supplemented by the Civil Aviation Regulations 1998, facilitates the issuance of airworthiness directives (ADs) to ensure the safety of air navigation. Specifically, under section 98 of the Act, the Governor-General can make regulations to enhance the safety of air navigation, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for specific types of aircraft or aeronautical products. These ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901. The ADs are primarily issued in response to obligations under the Convention on International Civil Aviation, where the State of Design holds responsibility for the continuing airworthiness of aircraft types. Australia, as a State of Registry, must ensure the continuing airworthiness of aircraft registered within its territory, and CASA, as the national airworthiness authority, must issue Australian ADs in response to ADs from States of Design, such as the US FAA, to maintain compliance with international standards. While the issuance of ADs does not require public consultation or a Regulatory Impact Statement, they are mandated by Australia’s international obligations and are issued under the authority of CASA.
Key Provisions
The Civil Aviation Act 1988 (section 98) and Civil Aviation Regulations 1998 (regulation 39.001) allow the Governor-General to make regulations for the safety of air navigation and empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific kinds of aircraft or aeronautical products. These ADs serve as crucial tools for maintaining the safety standards of aircraft and are issued in compliance with international obligations, specifically under Annex 8 to the Convention on International Civil Aviation. The State of Design, which is responsible for the continuing airworthiness of an aircraft type, issues these directives, and the State of Registry must then ensure that these directives are implemented for individual aircraft.
Under these regulations, CASA, as Australia’s national airworthiness authority, is obligated to assess any ADs issued by the State of Design and, if necessary, issue corresponding Australian ADs to enforce the requirements. This process ensures that all aircraft registered in Australia meet the required safety standards. In the case of the US Federal Aviation Administration’s (FAA) AD 2004-24-09 concerning Rolls Royce Corporation 250-B and 250-C series turboshaft engines, CASA issued the Australian AD/AL 250/85 in response to this directive. This Australian AD became effective on 17 March 2005, reflecting the need to align Australian aviation safety standards with international requirements.
The obligations imposed by the Civil Aviation Act and Regulations are clear and demand that CASA and other regulatory bodies act swiftly to implement ADs. These obligations extend to ensuring that the ADs issued are assessed for their relevance to Australian aircraft and that appropriate measures are taken to enforce compliance. The process is streamlined to ensure that safety is not compromised by delays, as ADs often address critical safety issues that require immediate attention. The authority to issue ADs without public consultation or a Regulatory Impact Statement is grounded in the urgency and importance of maintaining airworthiness standards.
Failure to comply with the requirements set forth in the ADs can lead to severe consequences. The Civil Aviation Act and associated regulations may impose penalties for non-compliance, which could include fines or other sanctions. Additionally, operating an aircraft that does not meet the airworthiness standards set by these directives can result in serious safety risks, potentially leading to accidents or incidents. The severity of the penalties and consequences underscores the importance of adhering to the ADs and maintaining the highest standards of aviation safety.
