AD/BELL 206/52 - Heater Fuel Line P/N 206-070-231-1 - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, were introduced to ensure the safety of civil aviation within Australia. These regulations, which include detailed safety directives and maintenance requirements, aim to address safety concerns and ensure the proper operation of aircraft. One such regulation, specifically targeting the safety of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, is the Airworthiness Directive (AD) numbered AD/BELL 206/52. This directive focuses on the inspection of the heater fuel line, part number 206-070-231-1, and applies to all models equipped with specific heater kit part numbers. The policy objective behind this directive is to mitigate potential safety hazards by mandating inspections within a specified timeframe, thereby enhancing overall aviation safety. The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), include comprehensive safety measures to prevent accidents and ensure the integrity of aircraft operations. AD/BELL 206/52 is an example of a targeted directive designed to address specific safety issues in certain helicopter models. By requiring inspections of the heater fuel line within 25 hours of time in service after 25 July 1973 or at the time of heater kit installation, the regulation aims to prevent potential failures and ensure the continued airworthiness of affected aircraft. This proactive approach is part of CASA's broader mission to maintain the highest standards of safety in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply to all entities and persons operating Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters within the Australian jurisdiction. Specifically, the legislation targets all models equipped with heater kit P/N 206-706-106-1, -3, -5 or -9, as referenced in SI 206-2, 206-43 or 206-77, and mandates compliance with Airworthiness Directive AD/BELL 206/52 concerning the inspection of the heater fuel line P/N 206-070-231-1. The directive requires inspections to be carried out within 25 hours of time in service after 25 July 1973 or at the time of heater kit installation, as documented in Bell SB No. 206-12-73-1, with Agusta referencing SB No. BT206-66. This regulation extends its applicability nationally and ensures adherence to safety standards outlined by the Civil Aviation Safety Authority. The scope of the legislation does not include any stated exclusions or exemptions, and it is enforceable through subordinate instruments that may provide further clarification or additional requirements.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, include a specific Airworthiness Directive (AD) for Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. This directive, AD/BELL 206/52, pertains to the inspection of heater fuel lines (P/N 206-070-231-1) for all models equipped with heater kit P/N 206-706-106-1, -3, -5, or -9, as referenced in SI 206-2, 206-43, or 206-77 (section 39-105). The directive is documented in Bell SB No. 206-12-73-1, with a corresponding Agusta SB No. BT206-66. The compliance requirement stipulates that inspections must be conducted within 25 hours of time in service after 25 July 1973 or at the time of heater kit installation. The Act imposes several obligations on the entities governed by this AD. Firstly, operators and owners of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters must ensure that the specified heater fuel lines are inspected as required. The inspection must be carried out within the stipulated timeframes to maintain airworthiness and safety standards. Operators must also ensure that any necessary repairs or replacements are documented and comply with the manufacturer's specifications as outlined in the referenced service bulletins. Failure to adhere to these requirements could result in the aircraft being deemed unairworthy. Non-compliance with the AD/BELL 206/52 can lead to significant consequences. Under the Civil Aviation Regulations, operators and owners who fail to conduct the required inspections and subsequent repairs may face enforcement actions. The potential penalties include fines, aircraft grounding, or even revocation of the aircraft's airworthiness certificate. The severity of the penalties depends on the extent of non-compliance and the risk posed to aviation safety. Civil Aviation Safety Authority (CASA) has the authority to enforce these provisions, ensuring that all governed entities maintain the required safety standards. In summary, the AD/BELL 206/52 mandates critical inspections of heater fuel lines for specific Bell and Agusta helicopter models. This directive, supported by detailed service bulletins, is essential for maintaining the airworthiness of the aircraft. Operators and owners are legally obligated to comply with these inspection requirements within the specified timeframes. Failure to do so can result in severe penalties, including fines and the potential grounding of the aircraft, underscoring the importance of adhering to these safety regulations.
