Narrative:
The aircraft, on a VOR instrument approach to runway 24, suddenly entered a heavy fog bank. The crew lost sight of the runway and ground; the aircraft struck the ground 1450 feet short of the runway and 600 feet to the right of the extended centerline.

PROBABLE CAUSE: "The Board determines that the probable cause of this accident was the deficient judgment and technique of the pilot during an instrument approach in adverse weather conditions in failing to abandon the approach when a visibility of one-eights mile was reported, and descending to a dangerously low altitude while still a considerable distance from the runway."
