The NTSB's narrative final · quoted from the NTSB record

While on a cross-country flight, the pilot encountered deteriorating weather. He contacted a FSS and requested to change his VFR clearance to IFR. Due to his inability to climb to an IFR MEA in visual conditions and crossing traffic, the IFR request was not accepted. He informed the controller he thought he was 'picking up tail plane ice' and would have to descend to better weather (visibility) conditions and plan an alternate route. Later in the day, the pilot's wife reported that he had not arrived, and an ALNOT was issued. The aircraft was found 5 days later where it had impacted into a mountain at 11,100 feet msl, near the area where the pilot had made the last radio contact. Impact marks showed that the aircraft was in level flight when it crashed. The aircraft partially burned following impact. Weather in the area, at the time of the accident, was reported as low clouds, with the mountain tops obscured, rain, and snow. Due to weather, access to the site by investigators was not achieved until 8/5/97. The accident occurred on 4/23/97.
