Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot of the tailwheel-equipped airplane reported that, during the takeoff roll, the airplane abruptly veered right, and he overcorrected to the left. The pilot then reduced the engine power to idle and overcorrected to the right. He attempted to correct by applying full brakes, but the airplane exited the runway to the left and nosed over. The airplane sustained substantial damage to the vertical stabilizer, rudder, and the right and left wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
