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

According to the certified flight instructor (CFI), the purpose of the flight was for the student pilot to practice landings. As the student began to flare for landing, the airspeed decreased and the airplane stalled about 3 to 5 feet above the ground. The airplane impacted the runway hard on the right main landing gear and bounced. The student pilot applied full engine power and the airplane veered off the right side of the runway, traveled up an embankment, and the left wing impacted the ground. During the accident sequence, the airplane sustained substantial damage to the left wing and fuselage. The CFI reported no preimpact mechanical anomalies with the airplane.
