While doing a wheel landing at the manchester airport, the aircraft swerved to the left. Applying full right rudder had no effect. Differential braking stopped the swerve, but I was unable to realign the plane with the runway before it left the pavement. The plane left the runway and rolled into a mixture of melting snow and mud. When the plane hit a foot-deep snowdrift, it flipped over onto its back. I feel that this problem can be prevented by greater experience with wheel lndgs, and in particular by learning to lower the tailwheel before the rudder loses its effectiveness. A contributing factor to the early loss of rudder effectiveness is that I had about a 5 KT tailwind during this landing. A tailwind will cause the rudder to lose effectiveness earlier than expected. In the future, I will be more aware of this factor.

Title: TAIL DRAGGER PLT LOSES CTL OF ACFT ON LNDG PROC ROLLOUT IN DOWNWIND LNDG.
Narrative: WHILE DOING A WHEEL LNDG AT THE MANCHESTER ARPT, THE ACFT SWERVED TO THE L. APPLYING FULL R RUDDER HAD NO EFFECT. DIFFERENTIAL BRAKING STOPPED THE SWERVE, BUT I WAS UNABLE TO REALIGN THE PLANE WITH THE RWY BEFORE IT LEFT THE PAVEMENT. THE PLANE LEFT THE RWY AND ROLLED INTO A MIXTURE OF MELTING SNOW AND MUD. WHEN THE PLANE HIT A FOOT-DEEP SNOWDRIFT, IT FLIPPED OVER ONTO ITS BACK. I FEEL THAT THIS PROB CAN BE PREVENTED BY GREATER EXPERIENCE WITH WHEEL LNDGS, AND IN PARTICULAR BY LEARNING TO LOWER THE TAILWHEEL BEFORE THE RUDDER LOSES ITS EFFECTIVENESS. A CONTRIBUTING FACTOR TO THE EARLY LOSS OF RUDDER EFFECTIVENESS IS THAT I HAD ABOUT A 5 KT TAILWIND DURING THIS LNDG. A TAILWIND WILL CAUSE THE RUDDER TO LOSE EFFECTIVENESS EARLIER THAN EXPECTED. IN THE FUTURE, I WILL BE MORE AWARE OF THIS FACTOR.
