The NTSB's narrative final · quoted from the NTSB record
While the pilot was descending toward the destination airport near the conclusion of the cross-country flight, the engine lost total power. The pilot subsequently performed a forced landing to a field, during which the right wing sustained substantial damage. During postaccident engine test runs, the engine lost power at high rpm settings. When the carburetor bowls were resealed, the engine ran with no anomalies noted. Both carburetor float bowls displayed contamination that likely affected the fuel flow to the engine; however, the extent to which the contamination contributed to the loss of engine power was not able to be determined during the investigation.
