NTSB Narrative Summary Released at Completion of Accident

The pilot stated that he was maneuvering over mountainous terrain in deteriorating weather conditions and reduced visibility when the airplane stalled. He pushed the nose down to recover from the aerodynamic stall and then abruptly pitched the nose up to avoid oncoming rising terrain. The airplane subsequently impacted trees and settled to the ground. The pilot reported no preimpact mechanical malfunctions or failures that would have precluded normal operation.

NTSB Probable Cause Narrative

The pilot‘s failure to maintain airspeed while maneuvering in mountainous terrain with reduced visibility, which resulted in an aerodynamic stall.
