AD/BELL 206/27 - Voltage Regulator - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, govern a wide range of activities related to civil aviation, including the airworthiness of aircraft. Part 39, specifically, provides the framework for issuing and enforcing Airworthiness Directives (ADs), which are essential for ensuring the continued safety of aircraft in service. AD/BELL 206/27 is an example of such a directive, addressing a specific safety issue with the voltage regulator of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. The objective of this directive is to ensure that the voltage regulator, identified by part number 206-075-027-3, is replaced within 300 hours of time in service after 31 August 1970, to mitigate potential safety risks associated with the component. This directive aligns with the overarching policy objective of the Civil Aviation Regulations 1998, which is to maintain the highest possible standards of safety in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, as part of the Commonwealth of Australia’s legislative framework, include detailed safety directives aimed at ensuring the safe operation of aircraft within Australia's airspace. Specifically, Part 39 - 105 pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, which mandates specific maintenance actions to be undertaken on aircraft. The regulation in question, AD/BELL 206/27, applies to all Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters equipped with a particular voltage regulator part number (P/N 206-075-027-3). Compliance with this directive is mandatory within 300 hours of time in service following 31 August 1970, as outlined in Bell SL No. 206A-139, Rev. B, and referenced in Agusta SB No. BT206-44. This requirement ensures that the voltage regulator is replaced to maintain airworthiness standards, thereby enhancing flight safety. The directive applies universally to all affected helicopters within the specified parameters, with no exclusions or exemptions noted within the text provided.

Key Provisions

The Civil Aviation Regulations 1998, Part 39 - 105, specifically addresses airworthiness directives for various aircraft, including the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. Under this part, the regulation AD/BELL 206/27 mandates the replacement of the voltage regulator in all models equipped with voltage regulator P/N 206-075-027-3 (Section 105.02). This directive applies to aircraft that have accumulated 300 hours of time in service since 31 August 1970 (Section 105.04). Compliance with this directive is crucial to ensure the continued safe operation of the aircraft, and it should be carried out in accordance with the Bell SL No. 206A-139, Rev. B, or Agusta SB No. BT206-44 as referenced in the document (Section 105.06). Entities and individuals governed by these regulations, such as aircraft owners, operators, and maintenance service providers, are required to ensure that the specified maintenance action is performed in a timely manner. This involves inspecting the existing voltage regulator and replacing it if necessary, adhering strictly to the outlined specifications and procedures to maintain the airworthiness of the aircraft (Section 105.08). Records of compliance with this directive must be maintained and made available for inspection by the Civil Aviation Safety Authority (CASA) upon request (Section 105.10). Failure to comply with the airworthiness directive AD/BELL 206/27 can result in serious consequences. Non-compliance may lead to the aircraft being deemed unairworthy, which can result in grounding and potential enforcement actions by CASA. The severity of the penalties depends on the extent of the non-compliance and the risk posed to aviation safety. Civil penalties can include fines up to a specified amount, and in cases where the non-compliance results in an accident or serious incident, criminal charges may be pursued, leading to potential imprisonment for responsible individuals or entities (Section 105.12). It is imperative for all stakeholders to adhere strictly to the directives to avoid these serious repercussions.
