AD/BELL 206/67 - Tail Rotor Drive - Inspection of Clamp Type Bearing Hangars

Overview

The Civil Aviation Regulations 1998, amended by F2006B04520, is a legislative instrument that plays a crucial role in ensuring the safety and airworthiness of aircraft operating within Australia. Enacted by the Commonwealth of Australia, this regulation is part of a broader legislative framework designed to address specific safety issues in civil aviation. In this case, the regulation was introduced to address the problem of tail rotor drive issues in Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, specifically focusing on the inspection of clamp type bearing hangars. This is evidenced by the inclusion of Airworthiness Directive AD/BELL 206/67, which requires the inspection of hangars with specific assembly numbers (206-040-338-5, 206-040-345-9, and 206-040-346-9) within 10 hours of time in service after 19 March 1975. The policy objective of this regulation is to ensure that all affected aircraft meet stringent safety standards, thereby reducing the risk of accidents and enhancing overall aviation safety within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the applicability of airworthiness directives as prescribed by the Civil Aviation Safety Authority (CASA). These regulations apply to all models of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters that include any of the specified hangar assemblies: 206-040-338-5, 206-040-345-9, and 206-040-346-9. The scope of this legislation is designed to ensure that these aircraft meet specific safety standards, particularly concerning the tail rotor drive. Compliance is mandatory, with inspections of clamp-type bearings in hangars to be performed within 10 hours of time in service after 19 March 1975, as outlined in Bell SB 206-75-1 Accomplishment Part II. This directive is equivalent to AD/Agusta 206/53. The Civil Aviation Regulations extend their reach across the Commonwealth, ensuring a uniform standard of aviation safety and operational integrity throughout Australia. Subordinate instruments may further clarify or extend the application of these directives, ensuring that all pertinent stakeholders are aware of and comply with the stipulated safety requirements.

Key Provisions

The main sections of the Civil Aviation Regulations 1998, PART 39 - 105, governing the airworthiness directives for Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, specifically focus on the inspection of clamp type bearing hangars, as detailed in AD/BELL 206/67. This directive applies to all models equipped with the hangar assemblies 206-040-338-5, 206-040-345-9, and 206-040-346-9. The compliance requirement is mandated within 10 hours of time in service after 19 March 1975, as outlined in Bell SB 206-75-1 Accomplishment Part II. The regulations impose specific obligations on the parties and entities governed by these directives. Primarily, operators of Bell 206 and Agusta Bell 206 Series helicopters must conduct a thorough inspection of the clamp type bearing hangars within the stipulated timeframe. The inspection must follow the detailed procedures provided in Bell SB 206-75-1 Accomplishment Part II. Failure to comply with these inspection requirements can lead to serious safety risks and potentially render the aircraft non-airworthy. In cases where operators fail to adhere to the airworthiness directives outlined in AD/BELL 206/67, several consequences may ensue. The Civil Aviation Safety Authority (CASA) can take enforcement actions against the operators. The severity of the consequences depends on the nature and extent of the non-compliance. Civil penalties can include fines and other monetary sanctions. For more severe breaches, criminal charges may be brought against individuals responsible for the non-compliance. The maximum penalties can vary, but they are designed to ensure compliance and maintain high safety standards within the aviation industry. The regulations underscore the importance of adhering to airworthiness directives to ensure the safety and reliability of aviation operations. Operators must not only comply with the inspection requirements but also maintain accurate records of all inspections and any actions taken as a result of those inspections. This documentation is crucial for regulatory audits and investigations. Non-compliance can result in operational disruptions, financial penalties, and legal actions, highlighting the importance of strict adherence to the stipulated requirements.
