## Narrative

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

(-23) AIRCRAFT DEPARTED TIMMERMAN AIRPORT (MWC) AT 10:11 AM CDT. DURING CRUISE FLIGHT AT 3,000 FEET AGL THE PILOT FELT STRANGE JERKING IN CONTROLS AND ENGINE RPM INCREASED. HE NOTICED THE AIRCRAFT WAS SINKING AT 500 FPM RATE AND REALIZED THE PROPELLER HAD COME OFF. HE LANDED IN A SOYBEAN FIELD WITHOUT FURTHER DAMAGE AT 10:37 AM CDT. THE PROPELLER DEPARTED THE AIRCRAFT DUE TO FAILURE OF THE 6 MOUNTING BOLTS. THE PROPELLER WAS NOT RECOVERED, HOWEVER ONE PARTIAL BOLT AND NUT WERE RECOVERED FROM THE ENGINE COWLING. EXAMINATION OF THE PROPELLER MOUNTING FLANGE AND PARTIAL BOLT INDICATES ALL THE MOUNTING BOLTS LOOSENED AND EVENTUALLY FAILED DUE TO FATIGUE CRACKING AND OVERLOAD.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
