Probable cause
The total loss of engine power due to a failed fuel control unit bearing.
NTSB analysis
The operator reported that the pilot was returning to the airport after completing an aerial application when the engine lost power. The pilot executed a forced landing to a pasture. An engine examination revealed that the fuel control unit (FCU) input drive shaft would not rotate. Further examination established that the FCU input drive spool bearing had failed; however, the cause of the bearing failure could not be determined. Maintenance records indicated that the FCU was within the inspection and overhaul requirements recommended by the manufacturer.
