Probable cause
The pilot's failure to maintain airspeed during a go-around in shifting wind conditions, which resulted in an exceedance of the airplane’s critical angle of attack and an aerodynamic stall.
Findings · 5
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 pilot reported that he experienced a bounced landing and initiated a go-around. He noted that the go-around was conducted in conditions that reduced the airplane's performance margin as he was operating at a low altitude, low airspeed, and a high gross weight. During the go-around, the airplane encountered shifting wind conditions and drifted left of the runway centerline. As the pilot attempted to correct the drift while establishing a climb, he exceeded the airplane’s critical angle of attack and entered an aerodynamic stall. The airplane subsequently impacted the ground, which resulted in substantial damage to the fuselage, wings, and empennage. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
