## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

UPON LANDING RUNWAY 9, PILOT WAS UNABLE TO REDUCE ENGINE POWER SO A GO-AROUND WAS INITIATED. DURING THE DOWNWIND APPROACH THROTTLE INPUT WAS NEEDED TO MAINTAIN ENGINE RPM. TURNING FOR FINAL THE PILOT PULLED THROTTLE CONTROL BACK TO REDUCE ENGINE RPM. THE ENGINE WENT TO LOW RPM AND WAS UNRESPONSIVE TO THROTTLE INPUTS. THE AIRCRAFT DID NOT HAVE ENOUGH ALTITUDE AND THE PILOT WAS FORCED TO LAND IN A CORN FIELD OFF THE APPROACH END OF RUNWAY 9.

## The NTSB's investigation of this event (1)

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
