The pilot said that he was spraying cherries when the engine suddenly stopped. He attempted an autorotation, but the main rotor impacted cherry trees. The helicopter's main bubble was shattered, and the skids and frame were bent. Postimpact examination of the aircraft, by a Federal Aviation Administration Inspector, revealed that the throttle cable's housing had broken, which permitted the engine's RPM to decay to the idle position.
