The corporate airplane was destroyed on impact with rolling terrain and fire 1.3 nm northeast of the Mission Sioux Airport (0V6), Mission, South Dakota. The flight was en route to the Rapid City Regional Airport, Rapid City, South Dakota, which was located 114 nm on a magnetic bearing 284 degrees from 0V6. The 290 foot long wreckage path was oriented on a magnetic heading of 290 degrees. Night meteorological conditions prevailed at the time of the accident. A witness and communications with the airplane/pilot indicate that the pilot had a continuous duty time of approximately 21 hours that began at least at 0414 mountain daylight time on the day prior to the date of the accident. The wreckage was distributed along 230 feet with propeller slash marks at the beginning of the wreckage path. Both propellers displayed twisting. Postaccident component examination revealed a preexisting crack in the right turbocharger's exhaust but no indication of melting of the fuel lines in the adjacent area. No other system anomalies were noted.
Probable Cause: the aircraft control not maintained by the pilot. A contributing factor was pilot fatigue.
