While passing the windsock, he noted the surface winds appeared to be a direct crosswind from right to left. The pilot then set up the airplane for a full stop landing. As the airplane touched down, the wind had shifted to a quartering tailwind and the wing and tail began to lift. The pilot applied full right aileron and up elevator in an attempt to maintain directional control, however, the airplane departed the runway surface, the propeller impacted the ground and the airplane flipped over, which resulted in substantial damage to the rudder. The pilot reported that the airplane had no preimpact mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N311PF](https://openairdocs.org/aircraft/N311PF), registered now, S/N CCK-2000-0028, built 2020 (OpenAirDocs) - Reported make and model: PF CUB FLYERS LLC CCK-2000 - Registry model: [PF Cub Flyers CCK-2000](https://openairdocs.org/model/pf-cub-flyers-cck-2000) (registry code 0563861) (OpenAirDocs) - Registry engine: [Lycoming YIO-360 EXP](https://openairdocs.org/engine/lycoming-yio-360-exp) (registry code 41710, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: CCK-2000-0028 - Year built: 2020 - Airframe hours: 94 - Engines: CubCrafters CC363i 186 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 28, 2022, 5 hours before - Airport: FGU, Collegedale Municipal Airport, runway 21, 4,986 × 75 ft, asphalt - Equipment: Stall warning system, Satellite tracking device, Electronic primary flight display, ADS-B, Angle of attack indicator, Auto-pilot, Electronic multifunction display ## Flight crew As NTSB recorded them.
