The biplane pilot reported that, during the landing roll, the biplane veered right. He applied left rudder and brakes, the left-wing tip scrapped the runway and the biplane exited the runway to the left. He then applied more brakes to avoid a drainage ditch and the biplane nosed down.

The pilot reported that the biplane sustained substantial damage to the lower, left-wing spar.

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