Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The purpose of the flight was for the student pilot to practice takeoffs and landings. The student was performing a soft field takeoff when the accident occurred. The student applied aft control pressure and added power for takeoff. Once airborne, the airplane drifted to the right. The student corrected and the airplane drifted to the left. The instructor then took control of the airplane. He lowered the nose to gain airspeed and the left gear contacted the runway and collapsed. The instructor stated he then overcorrected to the right and the right wing contacted the ground. The airplane settled to the ground off the right side of the runway and spun to the left prior to coming to rest. The airplane received substantial damage to the aft fuselage.
