Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to ensure the safety and efficiency of civil aviation in Australia. This legislative instrument specifically addresses safety directives for aircraft, including the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. The aim of this regulation, as detailed in PART 39 - 105, is to maintain and enhance the airworthiness of these helicopters by mandating regular inspections and necessary rework of specific components, such as the anti-torque control idler assembly. By setting clear compliance requirements, the regulation ensures that these helicopters continue to meet safety standards, thereby safeguarding both the aircraft and its occupants. The objective is to mitigate risks associated with the identified component, ensuring operational safety and reliability within the Australian aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, encompasses a detailed schedule of airworthiness directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safe operation of aircraft within Australia's airspace. This particular directive, AD/BELL 206/37, applies to all models AB206A, AB206B, 206A, and 206B of Bell Helicopter Textron Canada (BHTC) and Agusta Bell 206 Series helicopters with serial numbers referenced in the requirement documents, excluding those incorporating Service Instruction (SI) No. 206-60. The directive mandates inspections and rework of the anti-torque control idler assembly, with the applicable part number 206-001-746-5. Compliance is required in accordance with Service Bulletins 206-22 and BT206-54.12/72, which stipulate inspections within 25 hours of time in service after 30 November 1972 and rework within 100 hours of time in service after the same date. This directive is a critical component of ensuring the continued airworthiness of specified helicopters operating in Australia, with CASA overseeing adherence to these safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the Airworthiness Directive (AD) for Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters (section (1)). The directive concerns the Anti Torque Control Idler Assembly, P/N 206-001-746-5, and mandates an inspection and rework procedure (section (2)). This AD applies to all models AB206A, AB206B, 206A, and 206B with specific serial numbers, excluding those incorporating SI No. 206-60 (section (3)). The compliance requirements are outlined in Bell SB No. 206-22 or Agusta SB No. BT206-54.12/72 (section (4)). Under this legislation, the main operative sections require operators to conduct an inspection of the Anti Torque Control Idler Assembly within 25 hours of time in service after 30 November 1972 (section (1)). This inspection must follow the detailed steps outlined in paragraphs 1 to 5 of the specified service bulletin (section (2)). Additionally, operators must perform the rework of the idler assembly within 100 hours of time in service after 30 November 1972, adhering to paragraph 6 of the same service bulletin (section (3)). The directive aims to ensure the safety and airworthiness of the specified helicopter models by maintaining the integrity of the Anti Torque Control Idler Assembly. The obligations and requirements imposed by this Act on the parties or entities it governs include strict adherence to the inspection and rework timelines and procedures as outlined in the service bulletins. Operators must ensure that the Anti Torque Control Idler Assembly is inspected within 25 hours and reworked within 100 hours of the specified time in service. Non-compliance with these requirements could result in the aircraft being deemed unairworthy, potentially leading to operational restrictions or grounding of the aircraft until the necessary inspections and reworks are completed (section (4)). Failure to comply with the requirements of this Airworthiness Directive can result in significant legal and operational consequences. Under the Civil Aviation Regulations 1998, non-compliance is considered an offence and can lead to civil or criminal penalties (section (5)). The maximum penalties for non-compliance with airworthiness directives can include substantial fines and imprisonment, depending on the severity and intent behind the breach. Furthermore, operators may face additional regulatory actions such as the suspension or revocation of their Air Operator Certificate (AOC) or Pilot Licence, which could severely impact their ability to operate the aircraft commercially or privately (section (6)).
