The NTSB's narrative final · quoted from the NTSB record
THE PILOT ENTERED A PATTERN TO LAND ON RUNWAY 29, ALTHOUGH THE WIND WAS FROM 060 DEG AT 8 KTS AND ANOTHER AIRCRAFT WAS IN A PATTERN TO LAND ON RUNWAY 11. THE PILOT REPORTED THAT DURING THE APPROACH TO LAND WITH FULL FLAPS, HE HAD EXCESSIVE AIRSPEED AND ELECTED TO GO AROUND. INSTEAD OF GRADUALLY RETRACTING THE FLAPS, HE RETRACTED THEM 'ALL AT ONCE & TRIED TO CLIMB.' INSTEAD OF CLIMBING, THE AIRCRAFT SETTLED BACK TO THE RUNWAY. BY THAT TIME, THERE WAS INSUFFICIENT RUNWAY REMAINING TO STOP. THE AIRCRAFT CONTINUED OFF THE END OF THE RUNWAY AND HIT THE PERIMETER FENCE. DENSITY ALTITUDE AT THE AIRPORT WAS ABOUT 5000 FT.
