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 of the airplane reported that, while on final approach to the runway, the wind shifted, causing him to land with a tailwind. The pilot realized that he wouldn’t be able to stop the airplane on the runway, but believed the fence at the end of the runway prevented him from safely performing a go-around. The airplane overran the departure end of the runway, striking the fence and an occupied vehicle before impacting terrain. The airplane sustained substantial damage to the wings and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
