The student pilot reported he was “pretty slow” and flying about 200 feet above ground level when he entered a sudden steep left turn. The student pilot did not add power as he entered the turn and said he probably used too much aileron. During the turn the airplane suddenly entered a spin and impacted the ground in a steep nose down attitude. The impact caused substantial damage to all structural components of the airplane. The student pilot said he had about five hours of experience in the accident airplane and had not received any flight instruction in that type. In addition the student pilot stated he thought the cause of the accident was pilot error and that he should have kept a higher airspeed and been at a higher altitude.
