Aircraft Accident/Incident Report

Tuesady, February 15, 2000 15:30 CST
NTSB Narrative Summary Released at Completion of Accident
The airplane sustained substantial damage during a precautionary landing after experiencing ice accumulation in cruise flight. The pilot received a full weather briefing the previous night and updated weather on the day of the flight. The pilot updated his flight plan to change his route of flight to avoid an area of heavy precipitation. The aircraft began to accumulate ice in cruise flight. Other aircraft along the route of flight reported icing at altitudes above and below the accident aircraft's altitude. The rate of accumulation of ice began to increase and the pilot contacted air traffic control and requested and received clearance to climb. The airplane was unable to climb higher than about 8,000 feet msl. The ice accumulation rate was such that the heated windscreen would not keep the windscreen clear. The pilot contacted ATC and requested immediate vectors to the nearest airport, where he executed a precautionary landing. The runway was snow covered with a coating of ice beneath the snow, and the windscreen was still iced over. The aircraft slid off the runway and struck a snowbank. Postaccident examination of the aircraft failed to reveal any anomalies. The aircraft was equipped and certified for flight into known icing conditions.
NTSB Probable Cause Narrative
the pilots failure to maintain directional control. Factors to the accident were the icing conditions, the snow and ice covered runway and the snowbank.
