## Analysis

THE PLT CROSSED MID-FIELD, AND ENTERED A LEFT DOWN WIND FOR RWY 30. HE THEN CHECKED WIND DIRECTION, COMPLETED A BASE LEG, AND ENTERED FINAL APCH. AFTER REDUCING HIS AIRSPEED, THE ACFT 'FLOATED' PRIOR TO TOUCHING DOWN APRX 600 FT SHORT OF MID-FLD. THE PLT DECIDED NOT TO ATTEMPT A GO-AROUND AND IMMEDIATELY APPLIED BRAKES. HE THEN REALIZED THAT THE ACFT WOULD COLLIDE WITH AN ARPT BARRICADE (MADE OF TELEPHONE POLES) IF A LEFT TURN WAS NOT EXECUTED. THE PLT MADE A HARD LEFT TURN, AND THE ACFT'S RIGHT WING CONTACTED THE FIRST BARRICADE POLE. THE ACFT THEN PIVOTED TO THE RIGHT, AND COLLIDED WITH THE REST OF THE POLES. THE ACFT CAME TO REST BETWEEN TWO POLES, AND THE PLT AND TWO PASSENGERS EXITED THE ACFT THROUGH THE WINDOWS.
