Probable cause
The student pilot’s failure to maintain adequate airspeed and his exceedance of the airplane’s critical angle of attack during an attempted go-around, which resulted in an aerodynamic stall.
Findings · 3
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
Analysis
The solo student pilot reported that, during landing, the airplane "ballooned up and [he] added a little throttle [to] settle the [airplane]." He added that "the [airplane] seemed to settle but felt like it was coming down too fast." He applied full power to go around and reduced the flaps to 20°. He added that "the [airplane] was stalling and so [he] moved the flaps to 0 degrees, which caused the plane to continue to stall." Subsequently, the airplane impacted the ground. The airplane sustained substantial damage to the wings and empennage. The student pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
