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/owner of the experimental, amateur-built airplane said that the tower controller cleared him to land on runway 14, and advised that the wind was from 180 degrees at 12 knots gusting to 26 knots. The pilot elected to continue the landing, and during the landing roll, a "strong" gust of wind pushed the airplane off the left side of the runway, where it struck a runway light and sustained substantial damage to the empennage. The pilot reported that there were no mechanical deficiencies with the airplane that would have precluded normal operation.
