National Transportation Safety Board - Aviation Accident Factual Report:

Location: Englewood, CO
Accident Number: CEN20CA394
Date & Time: 09/15/2020, 1420 MDT
Registration: N596ST
Aircraft: Piper PA46
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 2 None
Flight Conducted Under: Part 91: General Aviation - Personal

The pilot was performing a straight-in approach to runway 35R, and the approach was "bumpy" due to winds and terrain. She reported that about touchdown, a "severe wind event caused what felt like a potential upset." The pilot felt the left wing lift up and an uncommanded downturn to the right. She 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 then landed and taxied to the ramp. The airplane sustained substantial damage to the rear wing spar and wing root. The pilot reported there were no mechanical malfunctions or failures that would have precluded normal operation.
