Probable cause
The loss of engine power for undetermined reasons.
NTSB analysis
The pilot stated that he was in cruise flight when the exhaust gas temperature (EGT) began to increase. He enriched the mixture slightly and the EGT returned to its previous value. Shortly thereafter, the EGT again increased and the pilot again enriched the mixture, resulting in the EGT returning to normal. This scenario repeated itself several more times before the engine lost power. Unable to restart the engine, the pilot selected a field and preformed a forced landing during which the airplane sustained substantial damage. While the airplane was operating in conditions conducive to carburetor icing at glide power at the time of the accident, the investigation was unable to determine if carburetor ice caused the power loss. Examination of the airplane and engine failed to identify a reason for the loss of engine power.
