Probable cause

The pilot's disregarding the weather forecast; his improper in-flight decision to continue a VFR flight into instrument meteorological conditions; and his failure to maintain adequate clearance from terrain. The mountainous hilly terrain and low ceiling were factors related to the accident.

Analysis

A pilot with over 17,000 hours flight time received a weather brief which reported low ceilings along his planned route of flight, and VFR flight was not recommended. He elected to go VFR and did not file a flight plan. Low ceilings were right where the weather briefer said they were reported to be, and they were obscuring the top of a mountain. The aircraft hit the side of the mountain about 100 feet below the crest.
