## Analysis

THE ACFT GROUNDLOOPED DURING TAKEOFF. THE PLT STATED THAT HE INCORRECTLY ASSUMED A 14 KT HEADWIND WHEN THE TOWER GAVE THE 'WINDS LIGHT AT FOURTEEN' AFTER PREVIOUSLY ASSIGNING RWY LIGHT. AFTER APPLYING POWER HE REALIZED THAT HE HAD A X-WIND AND CUT THE POWER. THE TAIL CAME AROUND AND THE LEFT WHEEL BROKE.
