Probable cause
The pilot's inadvertent encounter with a mound while landing on a remote airstrip.
NTSB analysis
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.
