Primary finding
Probable cause
The student pilot did not maintain sufficient airspeed during a steep turn after takeoff, which resulted in an aerodynamic stall.
Investigator assessment
Analysis narrative
The student pilot was practicing takeoffs and landings at an off-airport site. After departing a sandbar, he made a steep turn, which resulted in an aerodynamic stall and impact with terrain. The airplane sustained substantial damage to the wing spar and landing gear. The pilot reported no mechanical anomalies that would have precluded normal operation.
