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

The commercial pilot reported that the airplane was in cruise flight about 500 ft above ground level when the engine surged and experienced a partial loss of power. The pilot attempted to restore engine power, but was unsuccessful, and diverted to the nearest airport. Unable to reach the airport, the pilot conducted a forced landing to a field; the airplane nosed over upon touchdown. During a postaccident test run, the engine performed with no anomalies noted; therefore, the reason for the loss of engine power could not be determined.
