Probable cause
The pilot-in-command's attempted flight into known adverse weather conditions. Contributing to the accident was the high and gusty winds in the accident area.
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
The pilot was maneuvering the airplane to avoid weather. He attempted to fly over a hill and a downdraft began to push him into the hill. He applied full power but was unable to recover. Consequently, he executed a landing on the hilltop. Wind in the area was reported to be from the south at 60 knots. The pilot reported the wind to be from 110 degrees at 12 knots gusting to 20 knots.
