ANM07990005 enroute from pvu to tvy, in low visibility, aircraft contacted terrain at approximately 4700 feet. The pilot stated he had misjudged the terrain and descended too low. Pilot felt he was clear of the terrain and would be braking clear of the weather very soon. (.4)on October 29, 1998, at 1350 mountain standard time, a Piper PA-28-181, N3034B, impacted terrain during cruise flight approximately 10 miles south of Tooele, Utah. The private pilot and his passenger received minor injuries and the aircraft was destroyed by postimpact fire. Instrument meteorological conditions prevailed in the accident area and no flight plan was filed for this personal cross-country flight which originated from provo, Utah, at 1330. The flight was being conducted under title 14 CFR part 91. The intended destination was Tooele. According to the pilot, he was attempting to stay below the clouds, which resulted in colliding with terrain, when he inadvertently entered instrument meteorological conditions, in the form of fog, approximately 10 miles short of his destination. Witnesses, who were in the area where the accident occured, said fog was forming rapidly. The aircraft stuck terrain at an elevation of 6,200 feet above mean sea level (MSL) and the destination airport elevation was 4,316 feet MSL. The pilot said he had read and viewed tapes about mountain flying because this was his first experience in the mountains and he misread his map as to the terrain features and misjudged the fog conditions that were developing. He said he did not think the terrain elevation was as high was it was in the area where the accident occurred. In his written statement, the pilot stated he should have turned back when the weather conditions began to deteriorate.
