AN SMA PLT LOST CTL OF THE ACFT CLRING RWY AFTER LNDG.

Narrative

HAVING COMPLETED LNDG ON RWY 22 AND ARRIVING TO A FULL STOP (ON A-O-WINDSOCK INDICATION); I PROCEEDED TO EXIT RWY FROM R CTR WITH TXWY FORWARD R AT APPROX 40 METERS. I WAS STOWING FLAPS IN UP POS AND WAS MOMENTARILY IN HEAD LOWERED POS. ON LOOKING UP; DISCOVERED THAT THE ACFT WAS ROTATING TO THE L RAPIDLY AND WAS NOT RESPONSIVE TO FULL R INPUT ON THE PEDAL. I TRIED TO NOT USE THE BRAKE AND FELT THAT RAPID PWR APPLICATION WOULD ONLY MAKE THE CONDITION WORSE. THE L WING STARTED LIFTING AND AS I LOOKED OUT THE R SIDE; THE R WING WAS DROPPING AND I SENSED THE R GEAR SLIDING TO THE R. I THEN APPLIED BOTH BRAKES TO TRY TO KILL THE MOMENTUM TO PREVENT AN UPSET; WHEREUPON THE R GEAR BUCKLED UNDER AND THE R WINGTIP CONTACTED THE RWY. THE PROP SUSTAINED TOTAL BUCKLING ON 1 TIP. IN MITIGATION; I CAN ONLY RPT THAT DURING REMOVAL OF THE PLANE FROM THE RWY A VERY STRONG GUST FROM THE L QUARTER ON RWY 22 CAUSED ALL 4 OF THE PEOPLE REMOVING THE PLANE TO STRUGGLE FOR CTL. IT LASTED ABOUT 5-7 SECONDS AND THEN WAS DEAD STILL AGAIN; WITH THE SOCK HANGING FLAT.
