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 landing, the airplane touched down on the main landing gear and bounced twice. He initiated a go-around, but the airplane did not have enough airspeed. The airplane drifted to the left and the left wing contacted the ground. The airplane slid off the side of the runway and collided with terrain. Both wings were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
