NTSB narrative
The tailwheel equipped airplane sustained substantial damage when it veered off runway 13. The reported wind was 200 degrees at 10 knots. The pilot reported that he entered and flew a normal traffic pattern for runway 13. He reported that he did a normal wheel landing on the centerline with the right wing down and opposite rudder to compensate for the right crosswind. When the tailwheel contacted the runway, the airplane immediately veered to the left. He applied full right rudder and right brake but the airplane veered off the runway. The airplane sustained substantial damage to the left wing. The pilot reported that he taxied the airplane back to the ramp. The inspection of the airplane revealed the tailwheel was free to castor, as designed. The pilot reported he had 12,113 total hours of flight time of which approximately 8,000 hours were in tailwheel equipped airplanes. He reported he had flown 3.3 hours in the Stinson V77.
Probable cause
The pilot's failure to maintain directional control which resulted in a ground loop. A factor was the pilot's lack of familiarity with the airplane.

- 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.
