The NTSB's narrative final · quoted from the NTSB record
The pilot was en route to the destination airport when the airplane engine lost power, regained power, and then lost power again. The pilot said that he placed the mixture control in the full rich position, turned on the electric fuel pump, and moved the throttle control, but the engine did not regain power. The pilot attempted a forced landing on a corn field when the airplane struck two traffic signs that were adjacent to the field, substantially damaging the airplane wings. The pilot was uninjured. Inspection of the engine revealed no anomalies that would have precluded normal engine operation.
