Accident Sequence
The CFI-PIC stated that the CFI-trainee was performing a soft field takeoff with a 6 knot tailwind. After rotation, while attempting to accelerate, the airplane began veering to the left. The CFI-PIC applied full right rudder input, but the left turn continued. The CFI-PIC then reduced power, the right wing dropped, and the airplane impacted the ground. The airplane came to rest upright 180 degrees from the departure runway heading.
Aircraft Examination
Examination of the aileron and elevator flight control cables revealed no evidence of preimpact failure or malfunction. Impact damage to the airplane precluded determination of rigging of the aileron flight controls. Review of the airplane squawk sheets for the airplane revealed no discrepancies noted for the aileron flight controls. The engine was removed from the airplane, the impact damaged propeller was replaced, and the engine was started and found to operate normally.
Student Statement
According to another student of the flight school, while performing power-on and power-off stalls, full right rudder would not hold directional control and the left wing would stall first.
