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 pilot receiving instruction reported that while on final approach, the airspeed became slow so he lowered the airplane nose to increase the airspeed. The airplane landed firmly at the runway threshold and bounced. During the recovery from the bounce, the flight instructor commanded a go-around maneuver. During the go-around, the airplane’s nose rose high, and the airplane yawed and rolled to the left. The airplane impacted the ground alongside the runway and nosed over. Post accident examination revealed that the vertical stabilizer, rudder, empennage, and left wing sustained substantial damage. There were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
