Flight and Weather Briefing
The pilot obtained a weather briefing from an Automated Flight Service Station (AFSS) and filed an IFR flight plan. During the briefing, the pilot was issued an AIRMET for light to moderate mixed/rime icing in clouds and precipitation from the freezing level to 10,000 feet, with isolated severe icing in clouds. The freezing level along the route was between 2,000 and 4,000 feet. The briefer also provided a forecast for strong westerly winds, including winds at 9,000 feet from 280 degrees at 38 knots.
Descent and Adverse Conditions
After takeoff, the pilot climbed to a cruising altitude of 8,000 feet, above the clouds. En route, strong headwinds were encountered, prompting a request to descend to 6,000 feet. Air Traffic Control (ATC) issued an initial descent to 7,000 feet. During the descent, the pilot encountered severe turbulence and icing.
Emergency Landing
After descending below the clouds, the pilot could not maintain altitude and executed a forced landing downwind to a nearby airport. The reported winds at the airport were 250 degrees at 14 knots, gusting to 24 knots. During the landing, the airplane was blown off the runway into the runway lights.
Aircraft Equipment
The airplane was not equipped with anti-icing or deicing equipment, except for a heated pitot tube.
