The NTSB's narrative final · quoted from the NTSB record

The pilot reported that he had been flying for about 30 minutes when the engine lost total power. He flew the airplane toward a clearing for a forced landing, during which the airplane impacted a tree, resulting in substantial damage. Examination of the airplane and engine revealed no anomalies that would have precluded normal operation. Although weather conditions at the accident site were conducive to the formation of carburetor ice at cruise power settings, the pilot provided conflicting statements regarding his use of carburetor heat, and whether carburetor icing played a role in the loss of engine power could not be determined based on the available information.
