AD/BELL 206/66 - Tail Rotor Control Tube - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, form part of a comprehensive framework designed to ensure the safety and efficiency of civil aviation within the country. Specifically, Part 39 - 105 of these regulations includes the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which are instrumental in maintaining the airworthiness of aircraft by addressing identified safety issues through regulatory measures. This legislative instrument, F2006B04519, targets the inspection of the tail rotor control tube for Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, aiming to mitigate risks associated with the specified models and serial numbers. The directive, AD/BELL 206/66, requires compliance within 100 hours of time in service following 30 April 1975, as outlined in Bell SB 206-75-2 or Agusta SB No. BT206-94, reflecting a policy objective to enhance operational safety and reliability in aviation. The enactment of these regulations by the Commonwealth of Australia is a response to identified gaps in aviation safety protocols, ensuring that all stakeholders adhere to stringent safety standards. By mandating specific inspections and compliance timelines, the Civil Aviation Regulations 1998 aim to prevent potential safety hazards, thereby protecting both crew and passengers in civil aviation. The directive AD/BELL 206/66 is a practical application of this overarching safety policy, focusing on critical components like the tail rotor control tube to maintain the highest safety standards in the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, under Part 39 - 105, pertain to airworthiness directives issued by the Civil Aviation Safety Authority. Specifically, the regulation AD/BELL 206/66 applies to Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, including models 206A, 206B, AB206A, and AB206B with serial numbers as referenced in the requirement documents. This directive mandates an inspection of the tail rotor control tube and must be complied with within 100 hours of time in service following 30 April 1975. The applicability extends to aircraft documented in Bell SB 206-75-2 or Agusta SB No. BT206-94. The regulation is a Commonwealth instrument and thus applies nationwide, ensuring that all entities operating within Australia adhere to these safety standards. There are no stated exclusions or exemptions within the text of this specific airworthiness directive, and compliance is mandatory for the specified aircraft models. The regulation may be extended or clarified through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, Section 105, includes specific airworthiness directives that apply to certain aircraft models, such as the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 series helicopters. One key provision, identified as AD/BELL 206/66, pertains to the inspection of the tail rotor control tube (Section 105(4/75)Applicability). This directive is applicable to models 206A, 206B, AB206A, and AB206B helicopters with specific serial numbers as referenced in the requirement documents. The compliance requirement mandates that the inspection of the tail rotor control tube must be conducted within 100 hours of time in service after 30 April 1975, or as specified in the relevant service bulletins, Bell SB 206-75-2, or Agusta SB No. BT206-94. The obligations imposed by this regulation are straightforward yet critical for ensuring the safety and airworthiness of the specified helicopter models. Operators and owners must ensure that the inspection of the tail rotor control tube is performed by qualified personnel within the specified timeframe. This involves a thorough examination of the control tube for any signs of damage, wear, or defects that could potentially compromise the helicopter's safety during operation. The requirement documents, Bell SB 206-75-2 and Agusta SB No. BT206-94, provide detailed guidance on the inspection procedures and criteria for acceptable conditions. Failure to comply with the airworthiness directive AD/BELL 206/66 can lead to serious consequences. If an operator or owner fails to conduct the required inspection within the specified timeframe, it may result in the aircraft being deemed unairworthy. This could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The potential penalties for non-compliance include fines and other administrative actions that could affect the operator's license or the helicopter's airworthiness certificate. The seriousness of these consequences underscores the importance of adhering to the directive to maintain the safety standards set by the Civil Aviation Regulations.
