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. ## Factual narrative 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.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
