NTSB Narrative Summary Released at Completion of Accident

During a maintenance check flight of the helicopter, two auto-rotations at max gross weight with a neutral center of gravity were conducted. During the second maintenance check flight, on the initial run-up the pilot engaged the rotor clutch and heard a loud "bang". The cyclic control pulled from the pilot's hand, and the pilot rolled the throttle to ground idle to regain control the cyclic control. The helicopter rocked from left to right and rolled over on its side. Examination of the airframe found that the cyclic lateral control rod end bearing on the transmission fractured. Examination of the fractured surfaces showed features typical of overstress. No other mechanical or flight control malfunction was reported by the pilot.

NTSB Probable Cause Narrative

Failure of the cyclic lateral control rod end bearing, and subsequent dynamic rollover.
