Aircraft Accident/Incident Report

Columbus, Montana 59109
Sunday, July 26, 1998 9:15 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot stated that the engine was running rough, and he elected to make an off-field precautionary landing. He stated that he had checked the carburetor heat and magnetos, and had pumped the throttle; however, his measures were insufficient to improve the situation. He elected to make his precautionary landing in a hayfield; braking for the short field and obstructions resulted in the airplane nosing over. FAA inspectors inspected the airplane and engine after it was removed from the accident scene and found no evidence of a mechanical problem that could have resulted in a rough-running engine.

NTSB Probable Cause Narrative

Partial loss of power for undetermined reasons. Factors include the pilot's selection of unsuitable terrain for a precautionary landing.
