## Analysis

THE PLT WAS ON A LOCAL FLT TO CHECK THE AG ACFT AFTER IT HAD BEEN PARKED FOR SEVERAL MONTHS.  WHILE IN FLT, THE ENG SUDDENLY LOST ALL POWER. THE PLT MADE 2 RESTARTS, BUT THE ENG LOST POWER AGAIN AFTER EACH RESTART. A FORCED LANDING WAS SUBSEQUENTLY MADE IN A CORN FIELD WHERE THE ACFT NOSED OVER & WAS DAMAGED. AFTER THE ACDNT, THE ENGINE WAS CHECKED &IT RAN SUCCESSFULLY WITH NO MECHANICAL ANOMALIES OF THE POWERPLANT OR FUEL SYSTEM.
