LNDG PROC DOWNWIND LNDG RESULTS IN RWY EXCURSION.

Narrative

WE WERE ON AN IFR FLT BEING VECTORED TO THE ARPT FOR A VISUAL APCH. AT APPROX 5 MI W OF ARPT I CANCELLED THE IFR FLT PLAN AFTER IDENTING THE ARPT; AND CONTINUED TO THE ARPT VFR. I ATTEMPTED TO CONTACT THE ARPT OPERATOR THROUGH THE UNICOM 3 TIMES WITH NO RESPONSE. I THEN FLEW DIRECTLY OVER THE ARPT TO CHK THE WIND SOCK; AND INTERPRETED THE SOCK TO INDICATE A SW WIND. I THEN ENTERED THE PATTERN AND LANDED ON RWY 23. THE APCH AND LNDG SEEMED NORMAL; HOWEVER; OUR SPD SEEMED FAST AFTER TOUCHDOWN AND I WAS UNABLE TO STOP ON THE AVAILABLE RWY. WE CAME TO A STOP ABOUT 25 YARDS PAST THE END OF THE RWY. THERE WERE NO INJURIES WITH DAMAGE TO THE L MAIN GEAR; L FLAP; AND L PROP. AFTER EVERYONE EXITED THE ACFT; I STARTED WALKING UP THE HILL BACK TOWARD THE RWY TO SEE IF I COULD FIND SOMEBODY OR AT LEAST A TELEPHONE AT THE OPS OFFICE. IT WAS THEN THAT I REALIZED THE WIND WAS BLOWING DIRECTLY INTO MY FACE TELLING ME I HAD JUST ATTEMPTED A DOWNWIND LNDG ON A RELATIVELY SHORT RWY. IT IS HARD TO DESCRIBE HOW FOOLISH I FELT AFTER REALIZING THE ERROR I MADE INTERPRETING THE WIND SOCK; ESPECIALLY SINCE I AM A PROFESSIONAL PLT WITH CONSIDERABLE EXPERIENCE IN VARIOUS TYPES OF ACFT. HOWEVER; AFTER MUCH THOUGHT; I REALIZE I MADE SEVERAL ERRORS AND POOR DECISIONS THAT AFTERNOON; NOT JUST ONE. AS I MENTIONED; I HAVE CONSIDERABLE FLYING EXPERIENCE; BUT I WAS FLYING AN ACFT I HAD ONLY ABOUT 10 HRS AND 5 LNDGS IN SO I WAS NOT TOTALLY FAMILIAR WITH IT. NOT BEING ABLE TO GET THE LCL WIND FROM UNICOM; THERE WERE SEVERAL OTHER SOURCES WHICH I DID NOT USE AND SHOULD HAVE. I COULD HAVE ASKED THE APCH CTLR FOR WIND INFO FROM A NEARBY ARPT; OR I COULD HAVE LISTENED TO ATIS FROM A NEARBY ARPT SINCE IT WAS AVAILABLE. THEN WHEN MY PERCEPTION FROM THE WIND SOCK DID NOT AGREE; I WOULD HAVE KNOWN SOMETHING WAS WRONG. MY FRIEND IN THE R SEAT WHO HOLDS A PVT PLT LICENSE DID AGREE WITH MY INTERP OF THE WIND SOCK AND I PROBABLY ALLOWED HIS AGREEMENT TO REINFORCE MY ERRONEOUS READING OF THE WIND SOCK. I SHOULD NOT HAVE ALLOWED THAT TO HAPPEN; MY FRIEND HAS MINIMAL FLT EXPERIENCE AND I DID NOT CONSIDER HIM A QUALIFIED CREW MEMBER ON THIS TRIP. I WAS PIC. THE ARPT I LANDED AT HAS 2 RWYS; ONE IS 3100 FT; THE OTHER IS 2400 FT LONG. BECAUSE OF MY PERCEPTION OF THE WIND; I ELECTED TO USE THE SHORTER OF THE 2. I FEEL WITH MY LIMITED EXPERIENCE IN THE TYPE OF ACFT; THE LONGER RWY WITH A XWIND LNDG WOULD HAVE BEEN A BETTER CHOICE. I FEEL THE APCH AND LNDG WERE NORMAL; BUT AFTER TOUCHDOWN; I SLID MY R FOOT UP TOO HIGH ON THE BRAKE PEDAL CAUSING MY TOES TO HIT THE STRUCTURE UNDER THE INST PANEL AND DELAYING THE APPLICATION OF BRAKING. I ALSO DID NOT RAISE THE FLAPS AFTER TOUCHDOWN WHICH IS RECOMMENDED IN THE FLT MANUAL FOR MAX BRAKING EFFECTIVENESS. I AM NOT SURE IF THESE THINGS WOULD HAVE PREVENTED THE OVERRUN; BUT I FEEL THEY WERE CONTRIBUTIONS DUE TO MY LACK OF TOTAL FAMILIARITY WITH THE ACFT.
