The helicopter was facing into the wind and hovering, with an external load, over an open field adjacent to the work area. The pilot made a 180-degree right pedal turn to enter the work area, approximately 120 feet above the ground. While trimming for the left quartering tailwind, he heard a loud "pop" and felt a "thump" in his seat. He was unable move the cyclic control to the left, and the helicopter started a right banking turn. The helicopter rolled sharply to the right and impacted the ground. A postaccident examination of the helicopter revealed no discrepancies. Flight control continuity was established from the cockpit to the flight controls. When the flight controls were manipulated, no obstructions or binding were noted.
Probable Cause: Failure of the cyclic control system for reasons undetermined.
