When he flew by the windsock to check wind direction and speed, he noticed a significant crosswind was prevailing. After turning onto final approach, and after passing the point at which a go-around could be performed due to trees and terrain off the end of the runway, he noticed the wind had changed direction and was now a strong tailwind. He continued the approach and landed more than halfway down the runway, then aggressively applied the brakes to attempt to stop. The airplane subsequently nosed over and sustained substantial damage to the rudder and wings. The pilot reported that there were no preimpact mechanical malfunctions of the airplane that would have precluded normal operation. ## Aircraft - Registration: N958TW (not matched to a registry record) - Reported make and model: AVIAT A1 (C200) - Category: Airplane - Serial number: 3403 - Year built: 2022 - Airframe hours: 120 - Engines: Lycoming IO-360-A1D6 200 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Utility - Last inspection: Annual, October 4, 2023, 22 hours before - Departed: KDKX, Knoxville, TN - Destination: Same as departure - Airport: PVT, Pvt, runway 360, 1,200 × 80 ft, grass/turf - Equipment: Auto-pilot, Angle of attack indicator, ADS-B, Stall warning system, Satellite tracking device, Onboard weather ## Flight crew As NTSB recorded them.
