NTSB narrative
The airplane ground looped during the landing roll. The student pilot was flying solo at the time of the accident. The pilot reported that his first landing was "non-eventful" and that the airplane "performed well." The accident occurred on the second landing attempt. The pilot stated that during the landing rollout the airplane began "pulling very hard to the right" shortly after he "touched both brakes simultaneously... to slow the aircraft." The pilot reported that the "pull to the right was so strong that the aircraft began heading toward the side of the runway at about a 35 degree angle from [the runway] centerline." The pilot stated that he heard the "squeal of brakes" although he was "not applying brakes" while the airplane veered to the right. The pilot reported that he applied "hard left rudder" in an attempt to realign the airplane with the runway centerline. The pilot stated that the right landing main landing gear collapsed and the right wingtip impacted the ground. There were multiple tire tracks associated with the ground track of the airplane during the accident. These tire tracks were left by both the left and right main landing gear tires. The initial tire track was consistent with being left by the left main landing gear, arcing to the left. Next, there were two tire tracks marks, arcing to the right. These markings were consistent with being left by both the left and right main landing gear. The subsequent ground markings and tire track marks indicate the airplane ground looped to the left, with the right wing striking the terrain and the right main landing gear collapsing under the fuselage. No anomalies were detected with either brake system, and no discrepancies were noted during operational tests.
Probable cause
The pilot's failure to maintain directional control during the landing rollout which resulted in the encountered ground loop.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
