## Analysis

The pilot of the tailwheel-equipped airplane reported that, during the landing roll, the airplane veered to the right. He added that he attempted to correct the veer but was unsuccessful. The airplane continued to the right and exited the runway. During the runway excursion, the airplane nosed over. The airplane sustained substantial damage to the right forward lift strut and empennage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
