Incident Overview
A pilot operating under an IFR flight plan encountered icing conditions while en route. The aircraft experienced both structural icing and induction icing, causing the engine to lose power. The pilot initiated a descent as power began to diminish. Eventually, the engine lost all power, and the pitot tube became iced over.
Forced Landing and Impact
During the attempted forced landing in a small, unforested area, the aircraft impacted the terrain.
Weather Briefing
Investigation revealed that the pilot had limited his preflight weather briefing to selected DUAT system data and an abbreviated Flight Service Station briefing. As a result, he failed to receive an AIRMET warning that indicated occasional icing conditions along his intended route of flight.
