What happened
A private pilot, acting as the pilot in command, initiated a takeoff with a flight instructor occupying the rear seat. During a steep climb at an altitude of approximately 30 feet above ground level, a gust of wind lifted the left wing, causing the Cessna 150 to roll to the right.
Following a command from the flight instructor, the pilot closed the throttle. The aircraft subsequently impacted the side of the runway in a nose-down, wings-level attitude. The impact resulted in a propeller strike and the collapse of both main landing gear. The occupants were not injured.
Findings
The investigation found no mechanical anomalies with the aircraft that would have prevented normal operations.
