AD/BELL 206/68 - Main Rotor Pillow Block Bushings - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, serve to regulate various aspects of civil aviation, ensuring safety and operational standards across the industry. Within this legislative framework, Part 39 - 105 specifically addresses airworthiness directives, which are regulatory requirements aimed at correcting safety issues or deficiencies in aircraft. The Civil Aviation Safety Authority issues these directives to ensure that aircraft remain airworthy. The Airworthiness Directive AD/BELL 206/68, for instance, focuses on the replacement of main rotor pillow block bushings in Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. This directive was introduced to address a specific safety issue identified in these helicopter models, ensuring that maintenance actions are taken within a specified timeframe to prevent potential failures that could compromise flight safety. The policy objective of such directives is to maintain the highest safety standards in civil aviation by mandating timely and effective corrective actions.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, under the Civil Aviation Safety Authority (CASA) schedule of airworthiness directives, pertains to Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 series helicopters. This regulation applies to all models of these helicopters, as outlined in the applicable service bulletins such as Bell SB No. 206-75-3 and FAA AD 75-18-07, with a specific reference to Agusta SB BT206-97. The directive mandates the replacement of main rotor pillow block bushings within 600 hours of time in service following 28 November 1975. This requirement is equivalent to the AD/Agusta 206/54, ensuring uniformity in compliance across similar models. The application of this directive extends across the Commonwealth of Australia, governed by the Civil Aviation Safety Authority, which oversees adherence to these safety mandates within its jurisdiction.

Key Provisions

The Civil Aviation Regulations 1998 (CAR 1998) under PART 39 - 105, specifically within the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, detail requirements for maintaining the airworthiness of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. The directive AD/BELL 206/68 focuses on the replacement of Main Rotor Pillow Block Bushings. According to section (11/75), this directive applies to all models of these helicopters. The compliance must be achieved by referring to the relevant documents, either Bell Service Bulletin No. 206-75-3 or the FAA AD 75-18-07, with a note that Agusta Service Bulletin BT206-97 also pertains. Compliance with these directives is mandatory and must be completed within 600 hours of time in service after 28 November 1975. The Civil Aviation Regulations 1998 impose several obligations and requirements on the operators and owners of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. These requirements are designed to ensure the continued safety and airworthiness of these aircraft. Operators must follow the specific maintenance directives outlined in the referenced service bulletins to replace the Main Rotor Pillow Block Bushings. The regulations mandate that these changes be implemented within a specified timeframe of 600 hours of service post-November 28, 1975. Ensuring adherence to these directives is critical for maintaining the safety standards set forth by CASA. Failure to comply with the airworthiness directives outlined in AD/BELL 206/68 could result in significant legal and operational repercussions. The regulations stipulate that non-compliance could lead to the grounding of the aircraft until the required maintenance is completed. From a legal standpoint, operators and owners who fail to meet the stipulated requirements may face enforcement actions, including fines and potential criminal charges. The severity of penalties can depend on the extent of the non-compliance and any resultant safety issues. In cases of serious non-compliance, CASA has the authority to issue penalties that could reach significant financial amounts, reflecting the gravity of compromising aviation safety.
