PLT OF AN SMA CAUGHT BY STRONG WIND GUST CAUSED A BOUNCE AND DRIFT OFF THE RWY. SPD WAS TOO SLOW TO GAR AND ACFT WAS DAMAGED.

Narrative

AFTER MAKING 3 LNDGS TODAY IN THE SAME CONDITIONS AT NEARBY ARPTS; I WAS RETURNING TO MY 'HOME BASE' ARPT AND WAS LNDG TO THE N ON RWY 34. THE WIND WAS RPTED TO BE 280 DEGS AT 29 KTS WITH PEAK GUSTS TO 40-45 KTS. RWY 34 IS 5000 FT LONG WITH FIRST 500 FT TEMPORARILY DISPLACED DURING CONSTRUCTION. THIS WAS NOT A CONTRIBUTING FACTOR. I TOUCHED DOWN JUST BEYOND THE DISPLACED THRESHOLD WITH APPROX 10 DEG FLAPS AND ALIGNED WITHIN 5 DEGS OF THE RWY HEADING. AS SOON AS I TOUCHED DOWN; A STRONG GUST OF XWIND 'BALLOONED' THE ACFT BACK INTO THE AIR. HOWEVER; THE FORWARD AIRSPD HAD DECREASED CONSIDERABLY. THE XWIND FROM THE W CONTRIBUTED TO THE SECOND TOUCHDOWN BEING JUST OFF THE PAVED RWY ON THE GRASSY AND SOMEWHAT MUDDY AREA ON THE E SIDE BTWN THE RWY AND THE PARALLEL TXWY. ACFT WAS HEADED FOR A DRAINAGE DITCH WITH A CULVERT AND PERPENDICULAR TXWY SO I ADDED FULL PWR AND ATTEMPTED AN ABORTED LNDG 'GAR.' I CLRED THE DITCH BUT I DID NOT HAVE SUFFICIENT AIRSPD FOR THE ACFT TO BECOME AIRBORNE. I WAS UNABLE TO CTL THE DIRECTION OF THE ACFT AND DID NOT WANT TO GET ANY CLOSER TO OTHER ACFT PARKED OR TAXIING SO; I CLOSED THE THROTTLE AND STOPPED IN THE GRASS BTWN TXWY AND RAMP AREA. THE ACFT WAS DAMAGED IN L MAIN LNDG GEAR AND AILERONS. I WAS NOT HURT AT ALL.
