AD/F50/101 - Engine Controls - Automatic Flight-Idle Stop Control Unit - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, is designed to ensure the safety and efficiency of civil aviation within Australia. This legislation serves as the foundational framework for regulating air navigation and aviation safety, allowing for the creation of regulations and directives to maintain and enhance aviation safety standards. Under this Act, the Civil Aviation Safety Regulations 1998 were established to provide detailed operational and safety requirements. The issuance of airworthiness directives (ADs) under these regulations enables the Civil Aviation Safety Authority (CASA) to mandate safety measures for aircraft and aeronautical products, thereby ensuring compliance with international safety standards as stipulated by the Convention on International Civil Aviation. This regulatory approach aims to uphold the continuing airworthiness of aircraft registered in Australia, in alignment with the responsibilities of the State of Design and the State of Registry as outlined in Annex 8 of the Convention. The ADs function as crucial tools in communicating necessary safety information to maintain the safety and airworthiness of aircraft, reflecting a commitment to international safety protocols and domestic regulatory oversight.

Scope and Application

The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) which mandate safety standards for specific kinds of aircraft or aeronautical products. This authority extends to ensuring the continuing airworthiness of aircraft registered in Australia, particularly when directives from the State of Design, such as the European Union Aviation Safety Agency (EASA) on behalf of The Netherlands, necessitate such actions. These directives are legislative instruments, subject to disallowance and the Legislative Instruments Act 2003. The application of these directives is national, reflecting Australia's commitment to international aviation safety standards under Annex 8 of the Convention on International Civil Aviation. There are no stated exclusions or exemptions within the text, but the regulatory process does not require public consultation or a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. The ADs are issued by CASA, reflecting its role as Australia's national airworthiness authority.

Key Provisions

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide a framework for the issuance and management of airworthiness directives (ADs) for aircraft and aeronautical products. Section 98 of the Civil Aviation Act 1988 empowers the Governor-General to make regulations for the safety of air navigation, while regulation 39.001 of the Civil Aviation Safety Regulations 1998 allows the Civil Aviation Safety Authority (CASA) to issue ADs for certain types of aircraft or aeronautical products. This regulatory mechanism is essential for maintaining the safety and airworthiness of aircraft operating within Australia. Subregulation 39.001(5) further clarifies that ADs are considered disallowable instruments under section 46A of the Acts Interpretation Act 1901, and thus, they are legislative instruments as per section 6 of the Legislative Instruments Act 2003. Under these regulations, the State of Design has a primary responsibility for the continuing airworthiness of aircraft types, which involves providing necessary information to the States of Registry. This principle is underscored by Annex 8 to the Convention on International Civil Aviation, which mandates that the State of Design must supply relevant information to ensure the airworthiness of aircraft types. The State of Registry, in turn, must develop or adopt requirements to ensure the continuing airworthiness of aircraft registered within its jurisdiction. When a State of Design issues an AD, CASA, as Australia’s national airworthiness authority, must evaluate this information and, if deemed necessary, issue an Australian AD to enforce the requirements specified by the State of Design. This collaborative approach ensures that airworthiness directives are effectively implemented across different jurisdictions. In specific instances, such as the AD issued for Fokker F50 series aeroplanes, CASA must respond to ADs from other states, like the European Union Aviation Safety Agency (EASA), which acts on behalf of the Netherlands, the State of Design for these engines. The issuance of AD/F50/101 by CASA and its subsequent cancellation due to the issuance of AD 2009-0049R1 by EASA, demonstrates the dynamic nature of airworthiness management. It is important to note that this particular AD cancellation did not involve public consultation, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. The AD was made by the Manager, Continuing Airworthiness in the Airworthiness and Engineering Branch on behalf of CASA, in accordance with subsection 94(1) of the Act. The Civil Aviation Safety Regulations also outline the potential consequences of non-compliance with ADs. Breaching the requirements set forth in an AD can lead to civil and criminal penalties. For example, failing to comply with an AD may result in the grounding of an aircraft, which can have significant operational and financial implications for the aircraft operator. In severe cases, non-compliance with airworthiness directives can lead to criminal charges, including fines and imprisonment, depending on the severity of the breach and its impact on aviation safety. The precise penalties for non-compliance are determined by the specific circumstances of each case and are subject to the relevant provisions of the Civil Aviation Act 1988 and other applicable laws.
