Circumstances:
During cruise flight through an area of mountainous terrain, the commercial pilot became geographically disoriented and selected the incorrect route through the mountains. Upon realizing it was the incorrect route, he initiated a steep climb while executing a 180° turn. During the steep climbing turn, the airplane inadvertently entered instrument meteorological conditions, and the airplane subsequently impacted an area of rocky, rising terrain. The pilot reported there were no mechanical malfunctions or anomalies that would have precluded normal operation of the airplane.
Probable cause:
The pilot's failure to select the correct route through the mountains as a result of geographic disorientation, and his subsequent visual flight into instrument meteorological conditions, which resulted in collision with terrain.
