NTSB narrative
The pilot of a tailwheel-equipped airplane reported that he was landing on a remote airstrip. During the landing roll, a gust of wind forced the airplane slightly right of centerline about midfield. The right main landing gear then contacted an approximate 30-degree upsloping hummock (mound). The right main tire burst and the right main wheel imbedded in the mound. The airplane subsequently pivoted forward and left, with the left wing contacting the ground, before coming to rest upright. The impact resulted in substantial damage to the left wing. The pilot added that with the exception of the right main tire burst, there were no mechanical malfunctions or failures of the airplane.
Probable cause
The pilot's inadvertent encounter with a mound while landing on a remote airstrip.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2013-09-14.
