The NTSB's narrative final · quoted from the NTSB record
While practicing soft-field takeoffs in a single-control throw-over yoke aircraft, the student pulled the aircraft off the runway prior to attaining enough speed to remain airborne. Immediately after becoming airborne, the aircraft banked sharply to the left, dropped onto the runway, and bounced back into the air. According to the instructor pilot, when he saw that the aircraft was going to lift off prematurely, he commanded the student to lower the nose. But, the student did not lower the nose enough, and the instructor did not apply forward pressure to the central control pedestal to keep the aircraft from lifting off too early. It was later discovered that the left wing had impacted the asphalt surface when the aircraft dropped back onto the runway.
