The pilot applied left rudder control without affect. The airplane continued to track to the right and the right wing was substantially damaged when it struck a tree. After the pilot exited the airplane, he reported that there was a significant gusting wind from the north. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N682CC](https://openairdocs.org/aircraft/N682CC), registered now, S/N CC11-00421, built 2017 (OpenAirDocs) - Reported make and model: Cub Crafters CC11-160 (100) - Registry model: [Cubcrafters CC11-160](https://openairdocs.org/model/cubcrafters-cc11-160) (registry code 060006N) (OpenAirDocs) - Registry engine: [Titan OX-340CC](https://openairdocs.org/engine/titan-ox-340cc) (registry code 59470, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: CC11-00421 - Year built: 2017 - Airframe hours: 28.5 - Engines: Continental OX-340CC-B3J3N4 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental light sport (Special) - Last inspection: Annual, September 4, 2020, 468 hours before - Departed: MYL, Mc Call, ID - Destination: U60, Big Creek, ID - Airport: U60, Big Creek, runway 19, 3,550 × 110 ft, grass/turf - Equipment: Stall warning system, Satellite tracking device, Handheld GPS, Electronic flight bag or handheld device, Data recorder, Auto-pilot, Angle of attack indicator, ADS-B, Video recording device ## Flight crew As NTSB recorded them.
