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 certificated flight instructor and his student remained in the airport traffic pattern to practice several full-stop landings. While on approach the student flared high and the airplane dropped 8 to 10 feet, contacting the 3,375-foot-long by 50-foot-wide runway and then bouncing back into the air. While the pilot initiated a go-around, the airplane drifted left of the runway and the airplane's left wing impacted trees. The airplane sustained substantial damage to the wing spar and came to rest on the edge of the runway. Neither the flight instructor nor the student reported any mechanical failures or malfunctions of the airplane.
