Incident Overview
During an instructional flight, a private-rated student pilot was at the controls with a certified flight instructor (CFI) serving as pilot in command, as the student did not have a complex aircraft checkout. The student performed a power-off approach. On the base leg, when the aircraft appeared low, the CFI took over the controls to complete the approach.
Final Approach and Go-Around
When the final approach was overshot, the CFI initiated a go-around and attempted to raise the flaps to 10 degrees. During this maneuver, the aircraft stalled and descended with the left wing low, striking the ground. After impact, the aircraft cartwheeled.
Post-Crash Examination
A post-crash examination revealed that the flaps were fully retracted at ground impact. Inspection of the aircraft's engine, flight controls, flap system, and stall warning system showed no evidence of precrash failure or malfunction.
