AD/LYC/119 - ECi Cylinder Assemblies - CANCELLED

Overview

The Civil Aviation Act 1988, enacted by the Commonwealth Parliament, was introduced to provide a legislative framework that ensures the safety and efficiency of civil aviation in Australia. This Act empowers the Governor-General to make regulations that serve the interests of air navigation safety. The Civil Aviation Safety Regulations 1998, made under the authority of the Act, further elaborate on safety requirements and procedures, including the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA). These ADs are legislative instruments that mandate specific actions to maintain the airworthiness of aircraft and aeronautical products. The objective of these regulations is to align with international standards, particularly those outlined in Annex 8 of the Convention on International Civil Aviation, which assigns the State of Design the responsibility for continuing airworthiness and requires States of Registry to ensure the ongoing safety of aircraft. The issuance and enforcement of ADs by CASA aim to uphold these international safety standards and maintain the integrity of Australia's civil aviation system.

Scope and Application

The Civil Aviation Act 1988, supported by the Civil Aviation Safety Regulations 1998, mandates that the Civil Aviation Safety Authority (CASA) may issue airworthiness directives (ADs) for specific types of aircraft or aeronautical products. These directives are fundamental in maintaining the safety of air navigation, as they ensure that aircraft and related products meet continuing airworthiness standards. The ADs are legislative instruments, subject to disallowance and oversight as stipulated in the Acts Interpretation Act 1901 and the Legislative Instruments Act 2003. This legislative framework applies to all aircraft registered in Australia, as well as to aeronautical products used within the Australian aviation industry. CASA, as the national airworthiness authority, is responsible for assessing airworthiness directives issued by the State of Design and issuing corresponding Australian ADs if necessary. The responsibility of the State of Registry for the continuing airworthiness of individual aircraft is also underscored in the legislation. While the Act and Regulations broadly cover the issuance and implementation of ADs, specific instances such as the cancellation of AD/LYC/119 for Lycoming piston engines highlight the practical application and international coordination inherent in airworthiness directives.

Key Provisions

The Civil Aviation Act 1988, in conjunction with the Civil Aviation Safety Regulations 1998, provides the legal framework for issuing airworthiness directives (ADs) under regulation 39.001(5). These directives, as legislative instruments, are designed to ensure the safety of air navigation. They apply to specific types of aircraft or aeronautical products, and the Civil Aviation Safety Authority (CASA) is authorised to issue them. According to section 98 of the Civil Aviation Act 1988, the Governor-General has the power to make these regulations for the interests of safety. Furthermore, Annex 8 to the Convention on International Civil Aviation mandates that the State of Design has the primary responsibility for the continuing airworthiness of an aircraft type and must provide necessary information to the States of Registry to maintain airworthiness. Under the Civil Aviation Safety Regulations 1998, CASA, as Australia’s national airworthiness authority, is obligated to assess information from the State of Design and issue Australian ADs when necessary. This process ensures that the requirements set by the State of Design are enforced within Australia. The State of Registry, which is the country where the aircraft is registered, must develop or adopt requirements to ensure the continuing airworthiness of the aircraft. This shared responsibility between the State of Design and the State of Registry is crucial for maintaining safety standards globally. The issuance of ADs is governed by specific procedures and requirements. For instance, CASA issued AD/LYC/119 concerning Lycoming piston engines. However, this was superseded by the United States Federal Aviation Administration's (FAA) AD 2009-26-12 on 22 December 2009, leading to the cancellation of AD/LYC/119. The cancellation became effective on 4 February 2010. It is worth noting that no consultation with the Australian public was conducted regarding this cancellation, and the Office of Best Practice Regulation has determined that ADs do not require a Regulatory Impact Statement. Failure to comply with ADs can result in significant consequences. Under the Civil Aviation Act 1988, non-compliance with ADs can lead to various civil and criminal penalties. These penalties may include fines, imprisonment, or both, depending on the severity of the breach. The specific penalties are not outlined in the provided text, but they are generally intended to enforce compliance and ensure the highest safety standards are maintained in civil aviation.
