Analysis

The pilot of the tundra tire- and tailwheel-equipped airplane reported that, during the initial touchdown on the asphalt runway, the airplane bounced. She added engine power and continued to flare, but as the right main wheel touched down on the runway, the airplane veered to the right. She attempted to correct by adding full left rudder and slight brake pressure, but the airplane continued to the right. She then applied more brake pressure, and the airplane nosed over.

The airplane sustained substantial damage to the rudder and left-wing lift strut.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control and her use of excessive braking during landing, which resulted in a nose-over.

Findings

Directional control - Not attained/maintained (Cause)
Surface speed/braking - Not attained/maintained (Factor)
