Accident Details
A cross-country flight was underway when the pilot encountered clouds along the intended route near mountainous terrain. Recorded radar data and local weather reports indicated that the pilot was maneuvering near the cloud bases in an area with low visibility and low ceilings. The flight path was erratic and included circling maneuvers, suggesting the pilot had difficulty determining his location and desired flight track. The airplane subsequently collided with terrain.
Post-Accident Examination
Following the accident, investigators examined the airframe and engine. No mechanical failures or malfunctions were found that would have precluded normal operation of the aircraft.
Probable Cause Determination
The official probable cause was determined to be the pilot's loss of situational awareness while maneuvering under a cloud layer and failure to maintain sufficient clearance from mountainous terrain.
