Narrative:

During normal approach into dutchess county, ny (pou), ATIS reported winds light and variable. On short final, I determined that I was slightly high and so executed a slip. I crossed the numbers at 80 KIAS with red over white on the VASI-left. The aircraft floated down the runway, touching down long. Despite full aileron into the wind, the aircraft drifted right. During this time I was applying aerodynamic as well as wheel braking. The right wheel departed the runway short of the runway end and proceeded to overrun the runway. I executed a successful 180 degree turn on the grass, and proceeded to the FBO where I submitted a report to the tower. There were no damages, either to the aircraft or to airport equipment. There were no injuries. I believe that I was dealing with a significant tailwind. The pilot of another C172 reported a 90 degree crosswind of 10 KTS. This is my first incident. I should have gone around when I saw that I was landing long on the 3000 ft runway. Also, I neglected to ask for a wind check. While on final, I did not control my airspeed properly. I failed to control the aircraft.

Title: RWY EXCURSION LNDG OVERSHOT BY A LOW TIME C172 PVT PLT WHO TRIES TO SIDE SIP HIS ACFT ONTO THE 3000 FT RWY DURING A DESTABILIZED APCH AT POU, NY.

Narrative: DURING NORMAL APCH INTO DUTCHESS COUNTY, NY (POU), ATIS RPTED WINDS LIGHT AND VARIABLE. ON SHORT FINAL, I DETERMINED THAT I WAS SLIGHTLY HIGH AND SO EXECUTED A SLIP. I CROSSED THE NUMBERS AT 80 KIAS WITH RED OVER WHITE ON THE VASI-L. THE ACFT FLOATED DOWN THE RWY, TOUCHING DOWN LONG. DESPITE FULL AILERON INTO THE WIND, THE ACFT DRIFTED R. DURING THIS TIME I WAS APPLYING AERODYNAMIC AS WELL AS WHEEL BRAKING. THE R WHEEL DEPARTED THE RWY SHORT OF THE RWY END AND PROCEEDED TO OVERRUN THE RWY. I EXECUTED A SUCCESSFUL 180 DEG TURN ON THE GRASS, AND PROCEEDED TO THE FBO WHERE I SUBMITTED A RPT TO THE TWR. THERE WERE NO DAMAGES, EITHER TO THE ACFT OR TO ARPT EQUIP. THERE WERE NO INJURIES. I BELIEVE THAT I WAS DEALING WITH A SIGNIFICANT TAILWIND. THE PLT OF ANOTHER C172 RPTED A 90 DEG XWIND OF 10 KTS. THIS IS MY FIRST INCIDENT. I SHOULD HAVE GONE AROUND WHEN I SAW THAT I WAS LNDG LONG ON THE 3000 FT RWY. ALSO, I NEGLECTED TO ASK FOR A WIND CHK. WHILE ON FINAL, I DID NOT CTL MY AIRSPD PROPERLY. I FAILED TO CTL THE ACFT.
