## Analysis

THE PILOT STATED THAT THIS WAS HIS THIRD FLIGHT OF THE MORNING WITH A FULL LOAD OF FERTILIZER. REPORTEDLY, HE WAS IN THE PROCESS OF AERIAL APPLICATION, WHEN THE ENGINE QUIT. HE MADE A FORCED LANDING ON A SHORT FIELD ROAD. HE FURTHER STATED THAT THE GROUND ROLL WAS FINE UNTIL THE RIGHT MAIN LANDING GEAR STRUCK A BIG ROCK AND HE LOST DIRECTIONAL CONTROL. THE AIRCRAFT THEN WENT THRU A DITCH AND NOSED OVER. THE ENGINE WAS DAMAGED BEYOND ECONOMICAL REPAIR DUE TO AN INTERNAL CATASTROPHIC FAILURE.
