What happened
At the end of the second leg of a cross-country flight, the private pilot made an approach to runway 3 at the destination airport and subsequently performed a go-around. A flight instructor, who was about 3 miles from the airport and preparing to land on runway 21 did not hear any radio communications from the accident pilot. He observed the airplane in a climbing left turn near the departure end of runway 3, about 80 to 100 ft above the ground. The airplane then made a steep 45° to 60° bank to the right, with a nose-high attitude. As it progressed through the turn, the airplane's nose dropped, and it began a slow 270° rotation at a high descent rate. The airplane impacted the ground and came to rest upright on a grass area adjacent to the east side of runway 3.
Data from an onboard GPS confirmed the flight path described by the flight instructor and showed that the airplane's groundspeed was about 74 mph during the right turn. The airplane owner's manual indicated that the airplane's stall speed in a 60° bank varied from 90 to 96 mph indicated airspeed depending on flap setting.
Examination of the airframe and engine did not reveal evidence of any preimpact mechanical malfunctions that would have precluded normal operation. Based on witness information and recorded GPS data, it is likely that the pilot failed to maintain airspeed while maneuvering after the go-around, which resulted in an exceedance of the airplane's critical angle of attack, an aerodynamic stall, and subsequent loss of control.
