During landing roll on a remote airstrip, a gust of wind pushed a tailwheel airplane right of centerline, causing the right main gear to contact a hummock, bursting the tire and damaging the left wing.

Accident Sequence

The pilot of a tailwheel-equipped airplane reported that the incident occurred while landing on a remote airstrip. During the landing roll, a gust of wind forced the airplane slightly to the right of the centerline near midfield. As a result, the right main landing gear contacted an approximately 30-degree upsloping hummock (mound). The impact caused the right main tire to burst and the right main wheel to become imbedded in the mound. The airplane subsequently pivoted forward and to the left, with the left wing contacting the ground before the airplane came to rest upright.

Damage and Inspection

The impact resulted in substantial damage to the left wing. According to the pilot, aside from the right main tire burst, there were no mechanical malfunctions or failures of the airplane.
