Investigator assessment
Analysis narrative
The pilot of a tundra tire-equipped airplane reported that it veered right during landing rollout on a remote gravel bar. He attempted to correct the veer by applying left brake, but the airplane continued to the right, then the left tire dug into soft terrain, and the airplane subsequently nosed over. The airplane sustained substantial damage to the rudder and wings. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
