AD/INST/16 - King KG 102 Directional Gyro - Modification - CANCELLED

Overview

The Civil Aviation Act 1988 was enacted to provide for the regulation of civil aviation in Australia, with a strong emphasis on safety. Under this Act, the Governor-General has the authority to create regulations aimed at ensuring the safety of air navigation, which is further elaborated upon in the Civil Aviation Safety Regulations 1998. Specifically, these regulations empower the Civil Aviation Safety Authority (CASA) to issue airworthiness directives (ADs) for certain types of aircraft or aeronautical products. These directives, which are legislative instruments, play a crucial role in maintaining the continuing airworthiness of aircraft, in line with international standards set by the International Civil Aviation Organization (ICAO). The Civil Aviation Safety Regulations 1998 allow CASA to issue ADs when a State of Design issues a directive against a type of aircraft registered in Australia. CASA, as the national airworthiness authority, must evaluate this information and, if necessary, issue an Australian AD to enforce the requirements of the State of Design. The recent cancellation of Australian AD/INST/16, which affected King KG 102 Directional Gyros, exemplifies this process. Given that the unsafe condition addressed by the AD has been resolved, no further action is required, and the cancellation aligns with Australia's obligations under the Convention on International Civil Aviation.

Scope and Application

The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 provide the legal framework under which the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs). Specifically, section 98 of the Act allows the Governor-General to make regulations in the interest of air navigation safety, and regulation 39.001 of the Civil Aviation Safety Regulations 1998 empowers CASA to issue ADs for particular kinds of aircraft or aeronautical products. These ADs are legislative instruments subject to disallowance and the Legislative Instruments Act 2003. The application of ADs is aligned with Annex 8 to the Convention on International Civil Aviation, which places the responsibility for continuing airworthiness on the State of Design and the State of Registry. In Australia, CASA, as the national airworthiness authority, must evaluate and, if necessary, issue Australian ADs to enforce the requirements of foreign ADs issued against aircraft types on the Australian Register. The AD/INST/16 issued by CASA concerning King KG 102 Directional Gyros has been cancelled due to the resolution of the unsafe condition, and no further action is required. Notably, this AD cancellation was made without public consultation, and it does not necessitate a Regulatory Impact Statement as determined by the Office of Best Practice Regulation. The AD cancellation was executed by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in compliance with subsection 84A(2) of the Act.

Key Provisions

The Civil Aviation Act 1988 (section 98) and the Civil Aviation Safety Regulations 1998 (regulation 39.001) provide the framework for the creation and issuance of airworthiness directives (ADs). According to these provisions, the Governor-General has the authority to make regulations that serve the interests of air navigation safety, and CASA can issue ADs for specific types of aircraft or aeronautical products. These ADs are considered legislative instruments under the Acts Interpretation Act 1901 (section 46A) and the Legislative Instruments Act 2003 (section 6). Furthermore, as per Annex 8 to the Convention on International Civil Aviation, the State of Design is responsible for the continuing airworthiness of an aircraft type and must provide necessary information to the appropriate States of Registry. The obligations imposed by these regulations are multifaceted. Firstly, the State of Design must ensure the continuing airworthiness of an aircraft type by issuing relevant ADs. Secondly, the State of Registry must either develop or adopt requirements to maintain the airworthiness of the aircraft in its registry. In the case of Australia, the Civil Aviation Safety Authority (CASA) acts as the national airworthiness authority and is tasked with assessing information from the State of Design. If deemed necessary, CASA must then issue an Australian AD to enforce the requirements set by the State of Design. Breaches of these obligations can result in significant consequences. Although the specific offences and penalties are not detailed within the text, it is clear that non-compliance with airworthiness directives could potentially lead to safety violations and regulatory penalties. The Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998 likely include provisions for enforcement actions, which may encompass fines, suspension of airworthiness certificates, and other administrative measures. While the text does not provide specific maximum penalties, such breaches are likely to be taken seriously given the paramount importance of aviation safety. Additionally, the process for issuing or cancelling ADs is meticulously documented to ensure transparency and adherence to international standards. For instance, the cancellation of Australian AD/INST/16 affecting King KG 102 Directional Gyros was conducted in compliance with Australia's obligations under the Convention on International Civil Aviation. This particular AD was cancelled because the unsafe condition it addressed no longer existed, and no replacement AD was necessary. The decision to cancel this AD was made by the Manager, Systems and New Technologies, in the Airworthiness Engineering Group, on behalf of CASA, in accordance with subsection 84A(2) of the Act. Given the international nature of airworthiness directives, this cancellation was not subject to public consultation or a Regulatory Impact Statement.
