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 takeoff, the airplane veered to the left and exited the runway. The airplane subsequently nosed over and came to rest inverted, which resulted in substantial damage to the wings and 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 on runway 25 with a right quartering headwind at 7 knots.
