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 solo student pilot reported that, during approach, he was struggling to keep the airspeed at 60 to 70 knots, so he entered a side slip and reduced the power to idle. Once assured the airplane would reach the runway, he aligned the airplane with the runway. The airplane landed on the left main landing gear, bounced, and the student performed a go-around. He entered the left traffic pattern and landed without further incident. Postaccident examination of the airplane revealed substantial damage to the firewall and fuselage. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation station located on the airport reported that, about 6 minutes before the accident, the wind was from 270° at 6 knots. The airplane landed on runway 33.
