Aircraft Accident/Incident Report

Lacon, Illinois 61540
Saturday, August 10, 2002 13:30 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane sustained substantial damage during a precautionary landing. The pilot reported that while descending from cruise altitude he "noticed that the autopilot descend button had gotten progressively warmer. " The pilot stated he "turned off the autopilot and noticed that the panel around the autopilot was also very hot." The pilot reported he, "turned off the master switch thinking I may have the beginning of an electrical fire and started thinking of landing at the nearest airport. Within about a minute I smelled something hot or burning and I immediately picked out a field in which to land. I did not notice any smoke." The pilot reported he made the decision to perform the precautionary landing between 2,500 - 3,000 feet msl. The pilot performed the precautionary landing with the landing gear in the fully retracted position. The airplane was located in a cornfield that was approximately 4 nautical miles northeast of the nearest airport, which had two hard surfaced runways. There was no evidence of fire and/or smoke damage to the accident airplane. No discrepancies were identified with the autopilot unit and/or system.

NTSB Probable Cause Narrative

The pilot's improper in-flight decision to perform an intentional gear-up precautionary landing instead of continuing to the next available airport. A factor to the accident was the corn crop.
