AD/HU 269/111 - Lateral Control Trim Actuator Assembly

Overview

The Civil Aviation Act 1988 was enacted to provide a legislative framework for civil aviation in Australia, addressing the need for regulation and oversight to ensure the safety and efficiency of air navigation. This Act empowers the Governor-General to create regulations that serve the interests of air navigation safety, as outlined in section 98. One such regulation, 39.001 of the Civil Aviation Safety Regulations 1998, allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These ADs are legislative instruments under the Legislative Instruments Act 2003, reflecting their importance in maintaining the continuing airworthiness of aircraft as stipulated by Annex 8 to the Convention on International Civil Aviation. The issuing of these directives is a collaborative effort between the State of Design, which provides the initial information, and the State of Registry, which is responsible for implementing the necessary requirements for the aircraft within its jurisdiction.

Scope and Application

The Civil Aviation Act 1988, as supplemented by the Civil Aviation Regulations 1998, governs the issuance of airworthiness directives (ADs) in Australia. These directives are critical instruments for ensuring the safety and airworthiness of aircraft and aeronautical products within the Australian jurisdiction. The Act empowers the Governor-General to make regulations under section 98, with specific reference to regulation 39.001, which allows the Civil Aviation Safety Authority (CASA) to issue ADs for specific types of aircraft or aeronautical products. The ADs are considered legislative instruments under the Legislative Instruments Act 2003 and are subject to disallowance under section 46A of the Acts Interpretation Act 1901. The ADs are aligned with Annex 8 of the Convention on International Civil Aviation, which designates the State of Design as responsible for the continuing airworthiness of aircraft types and mandates the provision of necessary information to States of Registry. In Australia, CASA, as the national airworthiness authority, must assess and, if necessary, issue ADs to enforce the requirements specified by the State of Design. The scope of the ADs is such that they apply to all aircraft registered in Australia that fall under the types specified in the international directives, ensuring compliance with safety standards set forth by ICAO Contracting States, including the United States Federal Aviation Administration (FAA). The ADs do not require a Regulatory Impact Statement as determined by the Office of Regulatory Review.

Key Provisions

The Civil Aviation Act 1988, under section 98, empowers the Governor-General to enact regulations that promote the safety of air navigation. Specifically, regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments as per section 6 of the Legislative Instruments Act 2003, and they are disallowable instruments under section 46A of the Acts Interpretation Act 1901. ADs are essential tools for maintaining the continuing airworthiness of aircraft types, and they are issued by most International Civil Aviation Organization (ICAO) Contracting States. The State of Design for an aircraft type bears the primary responsibility for ensuring its continuing airworthiness, as stipulated in Annex 8 to the Convention on International Civil Aviation. This responsibility includes providing necessary information to the appropriate States of Registry to maintain airworthiness. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft within its jurisdiction. When a State of Design issues an AD, the State of Registry, in this case CASA as Australia’s national airworthiness authority, must evaluate the information and, if necessary, issue a corresponding Australian AD to enforce the requirements of the State of Design. The obligations imposed by these regulations are significant. The State of Design must issue timely and accurate information regarding any identified airworthiness issues, while the State of Registry, represented by CASA, must rigorously assess and act on these directives to ensure compliance and safety. CASA’s role includes evaluating the impact of foreign ADs on aircraft registered in Australia and issuing Australian ADs as required. This process ensures that all aircraft operating within Australia meet the necessary safety standards. Failure to comply with the provisions of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1990 can result in severe consequences. Civil penalties can be imposed for breaches of these regulations, including fines and other sanctions. The specific penalties are determined by the severity of the breach, with maximum penalties outlined in the relevant sections of the Act and Regulations. Criminal penalties may also apply in cases of gross negligence or willful misconduct, further emphasizing the importance of adherence to these safety measures.
