St Maries Municipal Airport
Aircraft Accident/Incident Report

St Maries, Idaho 83861
Saturday, October 6, 2012 17:14 PDT

NTSB Narrative Summary Released at Completion of Accident

The pilot reported that while descending the airplane from cruise flight toward his destination airport, the engine began to make unusual sounds and then lost total power. Despite the pilot’s attempts, the engine would not restart, so he initiated a forced landing to a nearby dirt road. During the landing roll, the left wing struck a tree, and the airplane nosed over and came to rest inverted. Postaccident examination of the engine and airframe revealed no preimpact mechanical malfunctions or failures that would have precluded normal operation. The weather conditions were not conducive to the formation of carburetor icing. The reason for the loss of engine power could not be determined.

NTSB Probable Cause Narrative

The total loss of engine power for reasons that could not be determined because postaccident examination of the engine and airframe did not reveal any anomalies that would have precluded normal operation.
