The twin-engine helicopter departed a field base during the early morning into the dark night to reposition the aircraft to a full service facility for maintenance. No radio/distress calls were received from the helicopter after the pilot called in his flight plan. The wreckage was found severely fragmented along a 300-foot long energy path located in coastal marshland approximately 4 nautical miles north of the field base. Detailed examination of the aircraft, engines, and drive components did not reveal pre-impact anomalies that would have contributed to the accident, and there was no evidence of an in-flight breakup or in-flight collision with an object. The pilot had over 11,200 hours of helicopter time, of which 316 were at night and 446 were under actual or simulated instrument conditions. The flight was conducted during the 11th and 12th hours of the pilot's 12-hour duty shift, which was his first night back from a two-week vacation during which he had been sleeping nights.
Probable Cause: the pilot's failure to maintain clearance with terrain for undetermined reasons. Contributing factors were the dark night and pilot fatigue.
