AD/BELL 206/70 Amdt 2 - Hydraulic Servo Actuator Support Assembly - Inspection

Overview

The Civil Aviation Regulations 1998, as part of the overarching legislative framework governing aviation safety in Australia, were enacted to establish and maintain the highest standards of safety and efficiency within the civil aviation sector. This regulatory instrument, managed and updated by the Civil Aviation Safety Authority (CASA), aims to ensure that all aircraft and aviation operations within Australia meet stringent safety requirements. The Regulations address the need for consistent and comprehensive safety measures across the aviation industry, reflecting the dynamic nature of the sector and the evolving technological landscape. The policy objective behind these regulations is to protect the public and aviation personnel by enforcing rigorous safety standards and ensuring that all aviation activities are conducted with the utmost regard for safety. Specifically, the legislative instrument F2006B04524 focuses on enhancing the airworthiness of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters by issuing Airworthiness Directives (ADs). These directives mandate specific actions, such as inspecting and modifying the hydraulic servo actuator support assembly, to mitigate identified safety risks. By doing so, the regulations aim to prevent potential mechanical failures and ensure the continued airworthiness of these aircraft models, thereby contributing to the overarching goal of maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, addresses the requirements for maintaining airworthiness of aircraft, including the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, through the issuance of Airworthiness Directives (AD). This legislation applies to all models of these helicopters with serial numbers as referenced in the requirement documents. The AD mandates that these helicopters undergo a specific inspection and modification of the hydraulic servo actuator support assembly. Compliance involves inspecting the hydraulic servo actuator support assembly at intervals not exceeding 100 hours of time in service and modifying it before a specified deadline, 31 December 1976, to ensure continued airworthiness. The regulations are enforced by the Civil Aviation Safety Authority and are applicable nationwide across Australia, reinforcing safety standards for civil aviation operations.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate that operators of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters comply with the Airworthiness Directives (AD). One such directive, AD/BELL 206/70 Amendment 2, concerns the inspection and modification of the hydraulic servo actuator support assembly. Operators must ensure that the hydraulic servo actuator support assembly attachment is inspected in accordance with Bell Service Bulletin (SB) No. 206-76-1 (Section 1). Furthermore, the assembly must be modified in accordance with Bell SB No. 206-76-8 Rev. “A” (Section 2). For Agusta models, SB Nos. BT206-101 and BT206-113, Rev. A are referenced. The directive applies to all models with serial numbers specified in the requirement documents (Applicability). Operators of these helicopters must adhere to strict timelines for inspection and modification. Inspections must be conducted at intervals not exceeding 100 hours of time in service until the modification is completed (Section Compliance). The modification must be carried out before 31 December 1976. Failure to comply with these requirements could result in the aircraft being deemed unairworthy, which would prevent it from operating. The directive is equivalent to AD/Agusta 206/57A, ensuring consistency across similar models. Under the Civil Aviation Regulations 1998, operators have the obligation to ensure that the specified inspections and modifications are performed by qualified personnel. This includes maintaining detailed records of all inspections and modifications conducted. Operators must also ensure that their staff is adequately trained to carry out these tasks in accordance with the relevant service bulletins. The regulations mandate that any non-compliance with these directives could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Breaching the requirements outlined in the AD/BELL 206/70 Amendment 2 can result in significant consequences. Civil penalties can be imposed for non-compliance, which may include fines up to the maximum allowed by law. In more severe cases, criminal charges could be brought against individuals or companies responsible for the non-compliance. These charges can lead to imprisonment, particularly if the breach results in an aviation accident or incident. Additionally, the aircraft may be grounded until the required inspections and modifications are completed, leading to operational disruptions and financial losses for the operator.
