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, while practicing stop and go landings, the airplane touched down and immediately veered left. The pilot attempted to correct with opposite rudder and brakes. During the braking action, the airplane subsequently nosed over and came to rest inverted, which resulted in substantial damage to the wing structure. The pilot stated that there was no mechanical malfunctions or failures with the airplane that would have precluded normal operations. At the time of the accident, the pilot was landing the airplane on runway 17 R (turf) with wind from 080 at 10 knots with gusts of 15 knots.
