## Analysis

THE AG ACFT WAS CLIMBING AFTER A PASS TO CLEAR POWER LINES AT THE NORTH END OF THE FIELD. THE MAIN LNDG GEAR CONTACTED THE TOP WIRE AS THE ACFT STARTED LEVELING OFF. THE WIRE DID NOT BREAK AND THE ACFT DESCENDED TO GROUND IMPACT. THE LNDG GEAR SNAPPED OFF AND THE ACFT SLID ON ITS BELLY ABOUT 30 FT BEFORE STOPPING.
