Probable cause

The pilot's inadvertent flight into IMC. Contributing factors related to the pilot's failure to request in-flight weather avoidance assistance and his misjudged evaluation of the en route weather.

Analysis

The non-instrument rated 2800-HR private pilot was experienced in the airplane and familiar with the route of flight. The pilot observed the dark overcast sky conditions in the direction of his planned trip, & indicated that while en route if the weather deteriorated he would return to the departure airport. The pilot took off under VFR conditions & headed in an easterly direction. Eight min later the pilot contacted radar & requested flight following service toward his easterly destination. Two min later the airplane was identified on radar, & two min thereafter radar contact was lost. The last four min of recorded radar showed that the airplane had climbed from 2600 ft to 3500 feet MSL & had turned 90 deg left from an easterly to a northerly course. Nearby weather reporting facilities indicated the cloud base & tops were respectively 3800 ft & 5700 ft MSL. The crash site was 4750 ft MSL.
