C172 PILOT IS BLOWN OFF TXWY BY STRONG GUSTY QUARTERING TAILWIND DESPITE BEST EFFORTS TO MAINTAIN CONTROL; CAUSING DAMAGE TO WING TIP AND PROPELLER.

Narrative

TOOK OFF EARLY IN THE MORNING (AROUND XA00 AM) FLEW FOR ABOUT 4 HRS AND HEARD PLTS HAVING WINDSHEAR AND GUSTY WIND PROBS AT ZZZ. SEARCHED FOR WX DATA FOR SURROUNDING ARPTS. ZZZ HAD WINDS RIGHT DOWN THE RWY AND WAS BEST CHOICE FOR LNDG. LANDED THE AIRPLANE FINE. WHEN TAXIING AFTER TURNING ONTO TXWY D AT THE ARPT THE NOSE DROPPED FORWARD; THE WIND LIFTED MY TAIL UP AND THE AIRPLANE WENT L WING DOWN OFF THE TXWY. I HAD THE PROPER WIND CORRECTION IN FOR A R QUARTERING TAILWIND. I LOST CTL OF THE PLANE AS IT WENT OFF THE TXWY OVER A PATCH OF GRASS AND ONTO AN ADJACENT SVC ROAD. I WAS ABLE TO STOP THE PLANE ON THIS SVC ROAD. THE FINAL WIND CHK I RECEIVED BEFORE LNDG WAS 290 DEGS AT 27 KTS GUSTING TO 34 KTS. THE ATIS RECORDED 300 DEGS AT 27 KTS GUSTING TO 42 KTS (UNCONFIRMED). I FEEL I TOOK ALL THE PROPER PRECAUTIONS TO PREVENT LOSING CTL OF THE AIRPLANE BUT WIND WAS JUST TOO STRONG TO PREVENT LOSS OF CTL. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE REPORTER STATED THAT THE ACFT FELT LIKE IT WAS BEING LIFTED BY A GIANT HAND DESPITE HIS BEST EFFORTS TO MAINTAIN CONTROL. THE ACFT ENDED UP AGAINST A SIGN WHICH PREVENTED FURTHER MOVEMENT. DAMAGE WAS DONE TO THE WING TIP AND THE PROPELLER WAS BENT.
