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 the airplane landed on centerline, immediately pulled to the left, and quickly left the runway. It continued until encountering a swampy area at which time the nose wheel dug in, and the airplane nosed over. The left wing strut and wing sustained substantial damage. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
