The NTSB's narrative final · quoted from the NTSB record

The student pilot was conducting a zero-flap takeoff when shortly after liftoff the airplane entered an unintentional right roll that neither the student pilot nor his flight instructor could correct with full left aileron and left rudder input. The airplane continued to roll right until the right wingtip struck the ground. The nose landing gear and left main landing gear separated from the airplane during the hard landing. The airplane sustained substantial damage to a fuselage longeron, the left side of the stabilator, and the right aileron. Postaccident examination of the airplane revealed no evidence of any preaccident mechanical failures or malfunctions that would have precluded normal operation. Flight control cable continuity was confirmed for the ailerons, rudder, and stabilator. The aileron system exhibited binding due to impact-related damage to the right aileron. The airport’s weather station reported a calm wind condition about 5 minutes before the accident. However, the airport manager reported that the surface wind at the time of the accident was from the southwest at 16.5 knots, gusting 19 knots. A postaccident weather model for the airport included a west surface wind (277°) at 9 knots. Based on the wind model data, the airplane likely departed runway 7 with an 8 knot left quartering tailwind. The unintentional right roll was likely due to the student pilot not maintaining adequate roll control after liftoff.
