Probable cause

The pilot’s misjudged landing flare that resulted in a hard landing. A contributing factor was the impact related failure of the tail wheel spring attachment bolts due to overload, which resulted in a ground loop.

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 stated that the airplane bounced and became airborne after landing firmly on the runway. As the airplane settled back onto the runway it veered to the left despite his control inputs. The airplane subsequently veered off the runway and ground looped. Examination of the airplane revealed that the left and right wings were structurally damaged. The tail wheel rudder spring attachment bolts were found separated and were located on the runway. The fracture surfaces of the bolts were consistent with overload. The pilot reported no pre accident anomalies with the flight control system.
