Action
Final rule.
Summary
The FAA is adopting a new airworthiness directive (AD) for certain Bell Helicopter Textron Canada Limited (now Bell Textron Canada Limited) Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 helicopters. This AD was prompted by a report that a certain tail rotor disc assembly, sold as an alternate part, does not conform to the approved configuration. This AD requires determining if an affected part is installed (by doing a maintenance records check or inspection), and if an affected part is found, replacement with a non-affected part. The FAA is issuing this AD to address the unsafe condition on these products.
