The NTSB's narrative final · quoted from the NTSB record

DURING THE FIRST PASS OF AN AERIAL APPLICATION FLIGHT, THE AIRCRAFT'S ENGINE STARTED TO BACKFIRE AND LOSE POWER. THE COMMERCIAL PILOT ELECTED TO MAKE A FORCED LANDING IN AN OPEN FIELD ADJACENT TO THE CORN FIELD HE WAS SPRAYING. THE AIRCRAFT ROLLED APPROXIMATELY 300 FEET TO THE END OF THE OPEN FIELD AS THE PILOT UNSUCCESSFULLY TRIED TO TURN THE AIRPLANE BEFORE CROSSING A DIRT ROAD AND ENTERING A CORN FIELD. THE AIRCRAFT'S RIGHT WING HIT A POST HIDDEN BY TALL WEEDS AND GRASS AT THE END OF THE OPEN FIELD, SUBSTANTIALLY DAMAGING THE AIRCRAFT. POST-ACCIDENT INVESTIGATION FOUND ONE CYLINDER CRACKED FROM SPARKPLUG HOLE TO SPARKPLUG HOLE, WITH THE TOP OF THE CYLINDER SEPARATING COMPLETELY. NO EVIDENCE OF PRE-IMPACT MECHANICAL MALFUNCITON WITH THE AIRFRAME OR ACCESSORIES WAS FOUND.
