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 reported that, during the takeoff roll on runway 18, the airplane veered left. The pilot attempted to correct with opposite rudder and aileron; however, the airplane exited the left side of the runway. During the excursion, the airplane rolled over a berm, and the left wing struck the ground. The airplane subsequently nosed over and came to rest inverted, which resulted in substantial damage to the right upper wing, left lower wing, vertical stabilizer, and rudder. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was departing from runway 18 with wind from 270° at 12 knots, gusting to 20kts.
