Aircraft Accident/Incident Report
Hillsboro, Oregon 97123
Saturday, December 30, 2006 9:50 PST
NTSB Narrative Summary Released at Completion of Accident
The pilot, who was flying to a location where he was going to meet family members for lunch, departed from an airport that was reporting clear skies, no precipitation, and nine miles visibility. About seven minutes after departure he encountered an area of solid undercast. The ambient conditions in the area made carburetor icing a strong possibility at both glide and cruise power, and soon after flying over the undercast the pilot experienced carburetor icing and his engine started to lose power. Although the aircraft's carburetor heat system was later found to be without anomaly, the pilot was unable to keep the engine running, and it eventually lost all power. He then was forced to descend through the thick layer of fog to attempt a forced landing in instrument meteorological conditions. During that attempted landing, the aircraft impacted the terrain, resulting in fatal injuries to the pilot.
NTSB Probable Cause Narrative
The loss of engine power during maneuvering flight due to carburetor icing, and inadvertent flight into instrument meteorological conditions. Factors were the ambient weather conditions conducive to carburetor icing and fog.
