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 Transport Canada has issued AD CF-2008-11 affecting DHC-8-400 model aircraft. Canada is the State of Design for this type. CASA has assessed this AD and has issued Australian AD/DHC-8/137, which will become effective on 8 February 2008.
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 establish a legislative framework governing civil aviation in Australia, aiming to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to create regulations that contribute to the safety of air navigation, including the issuance of airworthiness directives. The Civil Aviation Safety Regulations 1998, under regulation 39.001, further authorise the Civil Aviation Safety Authority (CASA) to issue airworthiness directives for specified kinds of aircraft or aeronautical products. These directives are considered legislative instruments and must be in accordance with international standards set by the International Civil Aviation Organization (ICAO). The authority to issue such directives is rooted in the obligation of the State of Design to ensure the continuing airworthiness of aircraft types, which CASA then enforces within Australia, ensuring compliance with both national and international aviation safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, under section 39.001, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products, in accordance with the Civil Aviation Act 1988. These directives are legislative instruments that mandate specific safety measures to ensure the continuing airworthiness of aircraft, particularly when such measures are issued by the State of Design as per Annex 8 to the Convention on International Civil Aviation. This jurisdictional framework ensures that Australia, as a State of Registry, meets its obligations to maintain the safety standards of aircraft registered within its territory. CASA, acting as the national airworthiness authority, evaluates ADs issued by other States of Design and, if necessary, issues corresponding Australian ADs to enforce the required safety measures. This process underscores the importance of international cooperation in maintaining aviation safety standards, and the authority of CASA to implement these measures without the need for public consultation or a Regulatory Impact Statement, given the critical nature of airworthiness directives.
Key Provisions
The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for ensuring the safety of air navigation in Australia, particularly through the issuance of airworthiness directives (ADs). Under section 98 of the Civil Aviation Act 1988, the Governor-General can make regulations that serve the interests of air navigation safety. Regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. These ADs are legislative instruments, subject to disallowance under section 46A of the Acts Interpretation Act 1901, and they must comply with the requirements of the Legislative Instruments Act 2003.
The State of Design, which is responsible for the continuing airworthiness of an aircraft type, must provide necessary information to States of Registry. Annex 8 to the Convention on International Civil Aviation outlines this responsibility, and ADs are the primary means of conveying continuing airworthiness information. The State of Registry, which is responsible for the continuing airworthiness of individual aircraft, must develop or adopt requirements to ensure this airworthiness. When a State of Design issues an AD, CASA must assess the information and, if necessary, issue an Australian AD to mandate the requirements of the State of Design. For instance, Transport Canada issued AD CF-2008-11 affecting the DHC-8-400 model aircraft, and CASA responded with Australian AD/DHC-8/137, effective from 8 February 2008.
The issuance of ADs such as the one in question is mandated by Australia’s obligations under the Convention on International Civil Aviation and is a response to an AD raised by the relevant State of Design. Consequently, no public consultation has been conducted on these ADs, and the Office of Best Practice Regulation has determined that they do not require a Regulatory Impact Statement. The AD in question was made by the Manager, Airframes in the Airworthiness Engineering Branch, on behalf of CASA, in accordance with subsection 84A(2) of the Act.
The obligations imposed by the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 include the responsibility of the State of Design to provide necessary information for continuing airworthiness, and the duty of the State of Registry to develop or adopt requirements to ensure airworthiness. CASA is required to assess any relevant ADs issued by the State of Design and issue Australian ADs as necessary. The failure to comply with these obligations can lead to significant safety risks, and CASA has the authority to enforce compliance through legal action. In terms of penalties, breaches of airworthiness regulations can result in civil penalties, including fines, and in severe cases, criminal charges may be pursued, with potential penalties depending on the seriousness of the breach.
