PLT OF AN ATX C206 LOST CTL OF THE ACFT DURING TAXI TO PARKING IN STRONG GUSTY WINDS CAUSING DAMAGE TO THE R WING AND PROP WHEN THE WIND BLEW THE ACFT UP ON THE R WING AND PROP.

Narrative

I AM SENDING THIS RPT IN HOPES IT WILL HELP OTHER PLTS FROM HAVING THE SAME EXPERIENCE. I AM A PLT FOR A PART 135 CHARTER SVC IN PUGET SOUND. I WAS ALONE AND FLYING A C206 AT THE TIME OF THE OCCURRENCE. THE WX CONDITIONS AT FRIDAY HARBOR ARPT WERE: WIND 140 DEGS 45 KTS GUSTING 58 KTS; CEILING ABOVE 30. I LANDED AT FHR ARPT ABOUT XC50 PM AND TAXIED TO CUSTOMS PARKING AT THE S END OF THE FHR TERMINAL BUILDING. I WAS INBOUND FROM CANADA. AS I WAS TAXIING I ASKED DISPATCH WHETHER I SHOULD COME TO OUR PARKING AT THE N END OF THE TERMINAL OR S TO CUSTOMS. (I WANTED N; SO I COULD KEEP THE WIND ON MY TAIL.) THEIR REPLY WAS TO CUSTOMS. I WENT FOR IT AND TURNED L TOWARDS CUSTOMS PUTTING THE WIND AT MY 7-8 O'CLOCK POS. I HAD FULL FLAPS DOWN AND FULL FORWARD AND R BANK INPUT ON THE CTLS. WHEN I GOT CLOSE TO THE TERMINAL WITH THE PORT OFFICE ON MY L AND IN FRONT; THE WIND SEEMED TO PICK UP IN INTENSITY AND REALLY START TO BUFFET THE ACFT AROUND. I DECIDED TO GET THE ACFT TURNED L INTO THE WIND. AT THIS TIME A GUST OF WIND PICKED UP THE L WING FOLLOWED BY THE TAIL. I PULLED THE MIXTURE CTL CUTOFF AS THE ENG WAS AT FULL IDLE; TO SAVE THE PROP AND ENG. (I WAS TOO LATE.) THE R WING HIT THE PAVEMENT AND THEN THE PROP; WHICH HAD TO TURN AT LEAST 3 MORE REVOLUTIONS. I THEN PUT THE FLAPS FULL UP AS THE ACFT SPUN AROUND AND SAT BACK DOWN ON THE GND. I HAVE FOUND SINCE THAT THIS 'WIND TUNNEL' EFFECT BY THE TERMINAL BUILDINGS HAS CAUSED SIMILAR ACCIDENTS BEFORE AT THIS LOCATION AND IS KNOWN TO LCL PLTS. A NOTICE OR SIGNS PLACED ON THE RAMP WARNING OF THIS PHENOMENON OF HIGHER GUSTY WINDS AROUND THE TERMINAL ON EXTRA WINDY DAYS WOULD BE APPRECIATED.
