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 landing on a wet grass runway, the airplane began to slide and he was unable to stop before the airplane departed the end of the runway into a soft, wet soybean field. The main landing gear dug into the soft soil and the airplane nosed over which resulted in substantial damage to the vertical stabilizer, empennage, and right wing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
