## Probable cause

The student pilot’s exceedance of the airplane's critical angle of attack during takeoff, which resulted in an aerodynamic stall.

## Findings

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

## Analysis

The solo student pilot reported that, during takeoff with a right quartering headwind and while between about 20 and 30 ft above ground level, the airplane aerodynamically stalled and then impacted the ground. The airplane sustained substantial damage to the left wing. The student reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

## Factual narrative
