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 after the completion of an aerial application flight, during the landing roll on a wet grass runway, the airplane slid off the left side of the runway, where the left wing subsequently impacted corn stalks, which "further drug the aircraft into the corn and ditch." The fuselage, wings, and empennage sustained substantial damage. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
