## Analysis

THIS AG OPERATOR WAS FERTILIZING A FIELD. HE WAS MAKING REPETATIVE TRIPS WHICH TOOK ABOUT 10 MIN EACH. THE PLT WAS AWARE THAT THE FUEL GAUGES WERE INACCURATE, READING LESS FUEL THAN WAS ACTUALLY ONBOARD. WHILE MAKING A SWATH RUN THE ENG LOST PWR AND THE ACFT STALLED DURING THE FORCED LANDING. POST ACCIDENT EXAMINATION REVEALED THAT THERE WAS NO FUEL IN EITHER THE ACFT OR ENG FUEL SYSTEMS AND NO EVIDENCE OF FUEL SPILLAGE AROUND THE WRECKAGE.
