Circumstances:
According to witnesses, the weather was changing from minute to minute as the aircraft was arriving. Witnesses reported the wind was blowing from east to northeast at 10 to 15 knots, rain fall was varying from strong to periods of light rain, and the ceiling (cloud level) was variable. The pilot began an ILS runway 36 approach; however, before reaching the airport, the aircraft collided with trees and crashed about 2 miles short of the runway. The pilot was seriously injured and could not remember the accident, but did recalled receiving a wind shear alert. The pilot reported an intermittent problem with the autopilot heading mode; however, no other preimpact malfunction or failure of the acft was evident. All five occupants were injured, two seriously.
Probable cause:
Collision with trees and terrain due to the pilot exceeding approach minimum altitude during an ILS approach.
