## Probable cause

The student pilot's improper landing flare which resulted in a bounced landing, loss of airplane control and subsequent collision with terrain.

## Findings

NTSB's coded findings; those marked are part of the probable cause.

## Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event best describes what happened.

## 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.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
