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 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.
