Narrative:A witness working in a field observed the helicopter fly overhead and heard the rotor blades making "funny noises." Shortly after, the witness lost sight of the helicopter and observed a plume of smoke. A postaccident examination of the helicopter revealed no pre-impact mechanical anomalies with the flight control system, rotor system, or engine. A technical representative of the helicopter manufacturer examined the photographs taken on scene, and reported that the main rotor blades displayed signatures consistent with a decay of the main rotor rpm.
Probable Cause: The pilot's failure to maintain main rotor rpm, which resulted in an uncontrolled descent and collision with terrain.
