Analysis

When the plt was cleared for takeoff, the tower was reporting a wind from 260 deg at 11 KTS. The takeoff was initiated & the acft accelerated normally. When the tailwheel was raised, the plane began drifting left. The plt said she applied rudder until she had full right rudder deflection, but the acft continued off the rwy & headed for a taxiway. The acft was lifted off the ground twice with insufficient airspeed to remain airborne. Finally, it stalled at about 20 ft AGL & contacted the ground right wing 1st. According to the passenger, the wind sock at the departure end of the rwy was limp.
