Overview

The Airworthiness Directives 2004, enacted by David Alan Villiers, a delegate of the Civil Aviation Safety Authority, under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998, addresses the need to update and maintain current airworthiness directives for various aircraft, specifically the Enstrom F-28 Series Helicopters. This legislative instrument revokes certain existing airworthiness directives and re-makes them to ensure they reflect the latest safety standards and regulatory requirements. The purpose of this directive is to ensure that all specified aircraft meet the necessary safety standards to maintain their airworthiness and to comply with the Civil Aviation Safety Regulations 1998. By updating these directives, the Civil Aviation Safety Authority aims to enhance the safety of aviation operations and mitigate any potential risks associated with the operation of the affected aircraft.

Scope and Application

The Airworthiness Directives 2004, promulgated by David Alan Villiers, a delegate of the Civil Aviation Safety Authority under subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998, applies to the Enstrom F-28 Series Helicopters. This legislative instrument revokes certain Airworthiness Directives and remakes others, with each remade directive mirroring the latest published version. The directives cover a broad spectrum of airworthiness concerns, from critical component inspections and modifications to retirements and safety measures. These regulations apply nationally, impacting all entities and individuals operating or maintaining Enstrom F-28 Series Helicopters within Australia. The legislative instrument does not explicitly state exclusions or exemptions; however, its application is contingent on the specifics outlined in each Airworthiness Directive. The authority to extend or restrict the application of these directives may be exercised through subordinate instruments, thereby providing flexibility in addressing emerging safety issues or technological advancements.

Key Provisions

The main operative sections of the Airworthiness Directives 2004 (F2006B07853) involve the revocation and remaking of specific Airworthiness Directives for Enstrom F-28 Series Helicopters, as detailed in Schedule 1 (section 2). The revocation of certain directives is explicitly stated, while others are remade in their current form, ensuring compliance with the latest standards and requirements. This action is taken to maintain the safety and airworthiness of these aircraft. Under this legislation, the obligations imposed on the parties and entities governed by the Act include adherence to the specified airworthiness directives. This encompasses compliance with the inspection, modification, and replacement requirements outlined for various helicopter components, such as the stabilizer spar attachment, main rotor spindle, and fuel tank vent. Operators and owners must ensure that their aircraft meet these standards to maintain compliance with safety regulations. Failure to comply with the airworthiness directives could result in civil and criminal consequences. Under section 9 of the Civil Aviation Act 1988, penalties for non-compliance can include fines up to $126,000 for individuals and $630,000 for corporations. Additionally, breaches may lead to criminal charges, resulting in imprisonment for up to two years for individuals and five years for corporations. These penalties underscore the importance of adhering to the stipulated airworthiness directives to ensure the safety and airworthiness of the aircraft.
