## Analysis

THE PLT REPORTED THAT DURING A LANDING, THE ACFT ENCOUNTERED A GUST OF WIND & BALLOONED. THE AIRSPEED DECREASED TO 40 KTS & THE ACFT DROPPED TO THE RWY. THE PLT APPLIED FULL POWER & REDUCED THE FLAPS FROM 40 DEG TO FULL UP. THE ACFT BECAME AIRBORNE, BUT TOUCHED DOWN AGAIN. IT THEN ROLLED ACROSS THE RWY, CROSSED A TAXIWAY & WENT INTO A DITCH. TOWER PERSONNEL STATED THAT THEY NORMALLY LAND GENERAL AVIATION ACFT ON RWY 11, RATHER THAN RWY 16, SINCE IT REQUIRES LESS TAXI DISTANCE. HOWEVER, RWY 16 CAN BE SPECIFICALLY REQUESTED BY THE PLT. AT THE TIME OF THE ACCIDENT, THE X-WIND COMPONENT WAS ABOUT 10 KTS.
