Probable cause

The failure of the pilot to use proper inflight planning to identify wind conditions (downdrafts) during the flight. As a result, the pilot was unable to maintain altitude and the airplane collided with mountainous terrain.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Analysis

While maneuvering in mountainous terrain, the airplane began losing altitude as it approached a pass. Unable to maintain altitude, the airplane was landed on a snow field. There were no reported mechanical failures or malfunctions with the airplane at the time of the accident.
