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 2004-26-09 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 250/86, 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, governs the regulation of civil aviation to ensure the safety of air navigation. Under this Act, the Civil Aviation Safety Authority (CASA) has the authority to issue airworthiness directives (ADs) to mandate requirements for the continuing airworthiness of aircraft types. This legislative framework is designed to align with international standards, particularly those outlined in Annex 8 of the Convention on International Civil Aviation, which assigns responsibility for airworthiness to the State of Design and the State of Registry. The Act enables CASA to issue ADs in response to directives from the State of Design, ensuring that Australian aircraft meet international safety standards. In this context, CASA issued AD/AL 250/86 in response to the US Federal Aviation Administration’s AD 2004-26-09 for Rolls Royce Corporation 250-B and 250-C series turboshaft engines, reflecting Australia's commitment to international aviation safety protocols.
Scope and Application
The Civil Aviation Act 1988, alongside the Civil Aviation Regulations 1998, provides the legislative framework through which the Civil Aviation Safety Authority (CASA) issues airworthiness directives (ADs) aimed at ensuring the safety of air navigation. These regulations empower CASA to mandate compliance with ADs for specific types of aircraft or aeronautical products. The application of these directives extends to the entire Commonwealth of Australia, impacting aircraft registered within Australia, their operators, and manufacturers of aeronautical products. The legislation does not specify particular exclusions or thresholds for the issuance of ADs but focuses on the overarching responsibility of maintaining airworthiness. The ADs serve as a crucial mechanism to uphold the safety standards mandated by the Convention on International Civil Aviation, requiring States of Design and States of Registry to collaborate on continuing airworthiness. CASA, as Australia's national airworthiness authority, plays a critical role in interpreting and implementing ADs issued by other countries, ensuring they meet Australian standards and legal requirements. The issuance of these directives is conducted in accordance with relevant sections of the Act and does not require public consultation or a Regulatory Impact Statement as determined by the Office of Regulatory Review.
Key Provisions
The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, outlines the mechanisms through which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) under section 98 of the Act and regulation 39.001 of the Regulations. These directives are critical for ensuring the continuing airworthiness of aircraft and aeronautical products, aligning with international standards set forth in Annex 8 of the Convention on International Civil Aviation. Specifically, section 98 empowers the Governor-General to enact regulations for air navigation safety, while regulation 39.001 mandates CASA's authority to issue ADs for specific aircraft types or aeronautical products.
The obligations imposed by the Act and Regulations require CASA to evaluate and, if necessary, mandate Australian ADs in response to directives issued by the State of Design, such as the United States in the case of the Rolls Royce Corporation 250-B and 250-C series turboshaft engines. CASA's role involves assessing the information provided by the State of Design, ensuring it meets Australian standards, and issuing an appropriate AD to maintain the safety and airworthiness of aircraft registered in Australia. The State of Registry, which in this context is Australia, must adhere to these mandates and ensure compliance with the continuing airworthiness requirements set forth in the ADs.
Failure to comply with the ADs issued under the Civil Aviation Act and Regulations can result in significant legal consequences. Non-compliance may lead to civil penalties, including fines and potential administrative actions against the aircraft operator or owner. Additionally, there could be criminal implications if the non-compliance results in a breach of safety regulations, potentially leading to imprisonment. The exact penalties vary depending on the severity and intent behind the non-compliance, but they serve as a deterrent to ensure adherence to airworthiness directives aimed at maintaining the highest safety standards in civil aviation.
