The amateur built helicopter was reported missing, and then located the following day. No information regarding the en route portion of the flight was available. No witnesses reported seeing the accident, and the pilot was not in radio contact with any air traffic control facilities, or automated flight service stations. The helicopter had a total of 25.6 hours of operation since construction. Examination of the wreckage revealed minor damage to both main rotor blades. Flight control continuity was confirmed from the cockpit to the main rotor and tailrotor. The transmission chip detector had metal fragments on it, the transmission oil contained suspended metal particles, and small pieces of metal were retrieved, with a magnet, from within the transmission. Examination of the engine revealed no preimpact failures or malfunctions.
