## Analysis

THE STUDENT PLT WAS ATTEMPTING TO LAND ON RWY 25 WITH A LIGHT X-WIND FORM 040 DEGS AT 5 KTS. THE PLT ALLOWED THE ACFT TO DRIFT TO THE LEFT OF THE NARROW RWY. AS FULL PWR WAS ADDED IN AN ATTEMPT TO GO-AROUND, THE ACFT STRUCK THE GROUND, VEERED LEFT THROUGH A FENCE AND THEN INTO A PLOWED FLD. THE PLT HAD PERFORMED 4 BALKED LANDINGS AT THIS ARPT DURING THE WEEK PRIOR TO THE ACCIDENT. ANOTHER BALKED LANDING WAS MADE DURING AN ATTEMPTED LANDING JUST PRIOR TO THE ACCIDENT LANDING. THE PLT REPORTED MOST OF HIS PRIOR EXPERIENCE WAS AT LARGER ARPTS.
