Bell Helicopter Textron, Inc. Helicopters
This AD applies to Bell Helicopter Textron, Inc. 205A-1, 205B.
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.
This amendment adopts a new airworthiness directive (AD), applicable to Bell Helicopter Textron, Inc. (BHTI) Model 205A-1 and 205B helicopters, that requires inspecting the vertical fin spar cap (spar cap) for cracking, corrosion, or disbonding; modifying the vertical fin; and replacing the left-hand spar cap. This amendment is prompted by five accidents involving helicopters of similar type design. The actions specified by this AD are intended to detect fatigue cracking or corrosion on the spar cap, which could lead to failure of the vertical fin spar, loss of the tail rotor, and subsequent loss of control of the helicopter.
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.
