Narrative:
A Rockwell Sabreliner 65, N265DS, impacted wooded terrain about 20 minutes after takeoff from Oxford-University Airport (UOX), Mississippi, USA. The aircraft was bound for Hamilton-Marion County Airport (HAB), Alabama.
At 15:06 the flight reported climbing through 1300 ft. ATC notified the flight of moderate to severe precipitation in the area of UOX and provided a clearance to 11000 ft MSL. At 15:08 ATC queried the flight for their altitude and informed the flight of moderate to heavy precipitation along their route of flight. The flight acknowledged the radio call and informed ATC they were climbing through 9000 ft for 11000 ft. About 15:12 ATC queried the flight if they were having navigation issues or if they were deviating. The flight responded they were deviating and that they were having "AC voltage problems." The last radio call received from the flight was an acknowledgement of a heading assignment to 095 at 15:13. The airplane disappeared from radar about 30 seconds later and the ATC controller tried unsuccessfully to raise the flight on the radio at that time.

Preliminary radar data began tracking the airplane at 15:06. The airplane transponder stopped transmitting Mode 3A information about 15:08, so no altitude information was available for the remainder of the flight. The airplane maintained an approximate heading of 080 from 15:06 until about 15:10. At 15:10 the airplane turned right to about 120 heading. At 15:12 the airplane made a left turn to about 040 heading. At 15:13 the airplane began a right turn that continued to a heading of about 270 until radar contact was lost at 15:13:26. The final radar return was about .5 miles southeast of the accident location.

Probable Cause: "An unidentified electrical system malfunction that led to the pilots losing awareness of the airplane's performance in instrument meteorological conditions and resulted in a loss of control of the airplane."
