Bell Helicopter Textron Canada Limited Helicopters
This AD applies to Bell Helicopter Textron Canada Limited 206A, 206B.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
We are adopting a new airworthiness directive (AD) for Bell Helicopter Textron Canada (Bell) Model 206A and 206B series helicopters. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority to identify and correct an unsafe condition on an aviation product. The aviation authority of Canada, with which we have a bilateral agreement, states in the MCAI: Transportation Safety Board of Canada (TSB) investigation into an accident involving Model 206B has revealed that the Spindle repaired by Cadorath Aerospace Inc., failed during flight resulting in loss of control of the helicopter. A similar repair was performed by H-S Tools & Parts Inc. This AD requires actions that are intended to address this unsafe condition related to certain repaired transmission pylon support spindles.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
