THE PILOT WAS INVOLVED IN AERIAL APPLICATION OF A PEST CONTROL SPRAY. HE REPORTED THAT DURING THE LAST SWATH RUN THE ENGINE 'STARTED HAMMERING' AND EVENTUALLY LOST POWER COMPLETELY. THE PILOT MADE A FORCED LANDING IN A MUDDY FIELD, AND THE AIRPLANE NOSED OVER DURING THE LANDING ROLL. AN FAA INSPECTOR ATTENDED A POST ACCIDENT ENGINE TEARDOWN. HE STATED THE NUMBER ONE CONNECTING ROD FRACTURED ABOVE THE ROD CAP ATTACH POINT, AND THERE WAS EVIDENCE OF GALLING ON THE REMAINING CONNECTING ROD JOURNALS. A SERVICE BULLETIN PUBLISHED BY THE MANUFACTURER STATES 'GALLING...IS PRODUCED DURING OVERSPEED OR EXCESSIVE MANIFOLD OPERATION.'
Probable Cause: THE LOSS OF ENGINE POWER DUE TO THE TOTAL FAILURE OF A CONNECTING ROD. RELATED FACTORS ARE THE LOW MANEUVERING ALTITUDE AND THE UNSUITABLE (MUDDY) TERRAIN ENCOUNTERED DURING THE FORCED LANDING.
