Aircraft involved
Probable cause & findings
The student pilot’s exceedance of the airplane's critical angle of attack during takeoff, which resulted in an aerodynamic stall.
Factual narrative
The student pilot reported that during takeoff with right quartering headwind, about 20-30 ft above the ground, the airplane aerodynamically stalled then impacted the ground. The airplane sustained substantial damage to the left wing. The student pilot, reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. 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.
