The pilot was conducting a night positioning flight and encountered instrument flight conditions. The pilot did not follow company procedures for instrument flight conditions, and lost control of the helicopter due to spatial disorientation. The helicopter entered a spiraling decent and collided with trees and ground. There were no mechanical anomalies with the helicopter. The pilot had logged 200 hours total time in the make and model helicopter, and no actual instrument time in any type of helicopter except for simulated instrument flight time. According to the company written procedures the pilot was required to follow the checklist which stated in part, "Fly the aircraft, climb to altitude, do not get in a hurry, and contact approach or center."

Probable Cause: The pilot continued visual flight into instrument meteorological conditions and experienced spatial disorientation, loss of aircraft control, and in-flight collision with trees and terrain. Factors in the accident were the pilot's failure to follow company procedures, total lack of instrument flight time, and a dark night.
