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 student pilot stated that he was practicing touch-and-go landings in the accident airplane. While approaching the runway at an altitude of about 400 feet, and while in the turn from the base to the final leg of the traffic pattern, the pilot described that he allowed the airspeed to get too slow and the airplane entered an aerodynamic stall. The airplane subsequently impacted trees and terrain, resulting in substantial damage to the fuselage and wings. The pilot reported that there were no mechanical malfunctions or failures of the airplane that would have precluded normal operation.
