Probable cause
The pilot's failure to maintain directional control during landing in gusting winds.
Investigator assessment
Analysis narrative
The pilot reported that the straight in approach for landing was "bumpy" due to winds and terrain. About touchdown, a "severe wind event caused what felt like a potential upset" as the left wing lifted and there was an uncommanded downturn to the right. The pilot applied full power to bank left and climb, but the airplane did not climb. The left-wing tip scraped the runway, and the airplane was forced to the right. Before the pilot was able to regain control, the airplane impacted a taxiway sign and several runway lights. The airplane sustained substantial damage to the rear wing spar and wing root. The pilot reported that there were no mechanical malfunctions or failures with the airplane that would have precluded normal operation.
