## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

ON 06/13/2010 AT APPROXIMATELY 18:20 PDT A WACO UKC-S AIRCRAFT, SERIAL NUMBER 3978,OWNED BY ^PRIVACY DATA OMITTED^ LOST CONTROL DURING LANDING AT THE BOEING FIELD INTERNATIONAL AIRPORT (KBFI) IN SEATTLE WASHINGTON CAUSING DAMAGE TO THE AIRCRAFT. THE PILOT AND ONE PASSENGER ONBOARD THE AIRCRAFT RECEIVED NO INJURIES. A STATEMENT WAS PROVIDED BY THE PILOT WHICH STATED THE LANDING DISTANCE OF THIS AIRPLANE IS APPROXIMATELY 600 FEET. WITH MAXIMUM AILERON DEFLECTION INTO THE WIND AND MAXIMUM OPPOSITE RUDDER, I ACTUALLY LANDED THE PLANE AND ROLLED OUT ABOUT 300 FEET AND THOUGHT THAT I HAD SUCCEEDED IN THIS CHALLENGING LANDING. I EVEN MADE A REMARK TO THE PASSENGER THAT I THINK WE GOT IT DOWN.HOWEVER AT ABOUT 300 FEET, A GUST LIFTED THE WINDWARD (RIGHT) WING. I ALREADY HAD FULL RIGHT AILERON AND FULL LEFT RUDDER HOWEVER THE VELOCITY OF THE PLANE WAS SLOWING AND CONTROL OVER THE RUDDER  AND CONTROL SURFACES WERE BEING LOST. I AVOIDED APPLYING ANY BRAKE PRESSURE WHATSOEVER. THE AIRPLANE "GROUNDLOOPED." THE PLANE'S LEFT WING BOW SCRAPED AND THE PLANE "VANED" INTO THE WIND AND LEFT LANDING GEAR (BEING SIDE-LOADED) COLLAPSED UNDER THE AIRPLANE AND THE PLANE SLID PERPENDICULAR TO THE RUNWAY UNTIL COMING TO A STOP. AS IT WAS SLIDING, I SHUT OFF THE MASTER AND THE MAGS AND IMMEDIATELY SHUT THE GAS TANK VALVES OFF AND INSTRUCTED THE PASSENGER TO EXIT THE PLANE.
