AD/BELL 205/58 - Time Expired Tail Rotor Yoke

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, addresses the issue of airworthiness directives for certain aircraft models, including the Bell Helicopter Textron 205 Series Helicopters. This legislation was enacted to ensure the safety and reliability of aircraft in Australia by providing specific guidelines and directives that must be adhered to by aircraft operators. The problem it was introduced to address includes the misrepresentation and misuse of critical aircraft components, which can compromise safety. This legislative instrument was enacted by the Commonwealth of Australia, with the policy objective of maintaining high safety standards in the aviation industry. The directive aims to ensure that certain parts, such as the tail rotor grips of specified Bell Helicopter models, are correctly maintained and not misrepresented as new or serviceable when they have exceeded their operational limits. The safety of the aircraft and its passengers is paramount, and this regulation seeks to prevent accidents and incidents that may arise from the use of compromised parts.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the oversight and management of airworthiness directives issued by the Civil Aviation Safety Authority (CASA). This legislative instrument, referenced as AD/BELL 205/58, applies to all Bell Helicopter Textron 205 Series helicopters that are equipped with aluminium tail rotor grips bearing the part number 204-011-728-19. The directive mandates that these helicopters must undergo an inspection and that any tail rotor grip with specific serial numbers must be removed from service. The serial numbers in question include A3-66287, A3-66365, A3-67171, A3-66333, A3-66370, A3-67184, A3-66356, A3-66377, A3-67207, A3-66361, and A3-67149. This directive extends to all operations within the Commonwealth of Australia and is enforced by CASA to ensure compliance with safety standards. The directive is applicable irrespective of the operator's status, whether commercial or private, and it supersedes any prior instructions or conditions. The directive became mandatory prior to further flight after 19 February 1990, following receipt of advice regarding the misrepresentation of previously operated tail rotor grips as new items.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, address the safety of Bell Helicopter Textron 205 Series Helicopters, particularly concerning the tail rotor yoke. One of the key provisions in this section, AD/BELL 205/58, mandates the inspection and removal from service of specific tail rotor grips (section 39-105). This directive applies to all models fitted with aluminium tail rotor grips with the part number 204-011-728-19 (section 39-105.1). The requirement is to inspect and remove from service any tail rotor grip with the serial numbers A3-66287, A3-66365, A3-67171, A3-66333, A3-66370, A3-67184, A3-66356, A3-66377, A3-67207, A3-66361, and A3-67149 (section 39-105.2). Entities governed by these regulations must ensure that the specified tail rotor grips are inspected and removed from service prior to further flight after 19 February 1990. This compliance requirement is intended to address safety concerns associated with the misrepresentation of tail rotor grips that have previously operated for 300 hours (section 39-105.3). Operators and maintenance personnel must adhere to these directives to prevent potential safety hazards. Failure to comply with these airworthiness directives can lead to significant legal and safety repercussions. The regulations do not explicitly state the penalties for non-compliance in the provided text, but it is reasonable to infer that non-compliance with safety directives could result in severe consequences, including fines and potential grounding of aircraft. The Civil Aviation Safety Authority (CASA) enforces these regulations, and non-compliance may result in administrative actions or legal proceedings against the offending parties. It is imperative for operators and maintenance personnel to ensure strict adherence to these safety directives to avoid any adverse outcomes.
