Read the full NTSB narrative
While in cruise flight, the helicopter experienced a hard right yaw and subsequent left nose tuck. The pilot was able to regain control of the helicopter and reduce the airspeed to under 100 knots. The flight continued to its destination without further incident. An examination revealed that the vertical stabilizer control system adapter failed. Metallurgical examination revealed that the failure mode was reverse bending fatigue. The vertical stabilizer control system adapter has since been redesigned. Installation of the improved design is now required by an Airworthiness Directive.
