Narrative:

After requesting an airport and traffic advisory from york, PA, the york unicom said wind 270 at 10 favoring runway 34. Approaching from the east I entered crosswind for 34 and flew a normal pattern. Looking down at the airport the wind T showed the wind right down the pipe for 34. I should have searched and disseminated the information from the wind sock(south). However(!!!), while making my landing on runway 34, I noticed my ground speed appeared a little high and it seemed like I was never going to T/D. During the roll out after landing in the last 50% of runway 34 I noticed a wind sock was showing the wind blowing from my left rear. More rear than left. During the refueling procedure I noticed another wind sock showing the wind from the same direction as the first. I queried the lineman about the situation. He said the wind T was a manual type, then promptly walked out and swung the wind T to show the wind blowing right down the pipe for 16 with the wind sock showing 10-15 KTS southwest. Obviously, this wind T is not used for wind direction but for runway in use, which is what the radio is for. I was glad there was more than 1 wind sock and I'll be sure to locate as many wind indicators as I can and rely less on local experts. The wind T should be made operable for standard use or removed. This event really frustrated me after landing.

Title: GA SMT TAIL WIND LNDG DUE TO INDICATION OF WIND TEE WHICH IS MANUALLY OPERATED.

Narrative: AFTER REQUESTING AN ARPT AND TFC ADVISORY FROM YORK, PA, THE YORK UNICOM SAID WIND 270 AT 10 FAVORING RWY 34. APCHING FROM THE E I ENTERED XWIND FOR 34 AND FLEW A NORMAL PATTERN. LOOKING DOWN AT THE ARPT THE WIND T SHOWED THE WIND RIGHT DOWN THE PIPE FOR 34. I SHOULD HAVE SEARCHED AND DISSEMINATED THE INFO FROM THE WIND SOCK(S). HOWEVER(!!!), WHILE MAKING MY LNDG ON RWY 34, I NOTICED MY GND SPD APPEARED A LITTLE HIGH AND IT SEEMED LIKE I WAS NEVER GOING TO T/D. DURING THE ROLL OUT AFTER LNDG IN THE LAST 50% OF RWY 34 I NOTICED A WIND SOCK WAS SHOWING THE WIND BLOWING FROM MY LEFT REAR. MORE REAR THAN LEFT. DURING THE REFUELING PROC I NOTICED ANOTHER WIND SOCK SHOWING THE WIND FROM THE SAME DIRECTION AS THE FIRST. I QUERIED THE LINEMAN ABOUT THE SITUATION. HE SAID THE WIND T WAS A MANUAL TYPE, THEN PROMPTLY WALKED OUT AND SWUNG THE WIND T TO SHOW THE WIND BLOWING RIGHT DOWN THE PIPE FOR 16 WITH THE WIND SOCK SHOWING 10-15 KTS SW. OBVIOUSLY, THIS WIND T IS NOT USED FOR WIND DIRECTION BUT FOR RWY IN USE, WHICH IS WHAT THE RADIO IS FOR. I WAS GLAD THERE WAS MORE THAN 1 WIND SOCK AND I'LL BE SURE TO LOCATE AS MANY WIND INDICATORS AS I CAN AND RELY LESS ON LCL EXPERTS. THE WIND T SHOULD BE MADE OPERABLE FOR STANDARD USE OR REMOVED. THIS EVENT REALLY FRUSTRATED ME AFTER LNDG.
