## Analysis

THE PILOT ATTEMPTED TO TAKEOFF FROM A 1200 FT ALFALFA FIELD WITH A LOAD OF SEED BUT WAS UNABLE TO OBTAIN FLYING SPEED. BY THE TIME HE REALIZED THE SITUATION, THERE WAS NOT ENOUGH ROOM TO STOP. HE REPORTED THAT HE RELEASED THE BACK PRESSURE UNTIL HE WAS NEAR THE END OF THE FIELD, THEN HE PULLED BACK ON THE STICK HOPING TO RISE OVER THE FENCE AND SETTLE IN THE ADJOINING FIELD. HOWEVER, THE PLANE WENT THROUGH THE FENCE. THE LEFT WIND HIT A CORNER POST, THE PLANE SWUNG SIDEWAYS, THE GEAR COLLAPSED, THEN THE PLANE WENT THROUGH A SECOND FENCE. NO MECHANICAL FAILURE OR MALFUNCTION WAS REPORTED.
