During the landing, the airplane yawed to the right. The pilot corrected to the left and aborted the landing. As the airplane rotated, it impacted an airport sign. The pilot continued and as the airplane climbed, it began rolling to the left. The pilot decided to land in the field off the end of the runway. Upon touchdown, the left wing and tire impacted first and the airplane came to rest upright on the on the sidewalk of an airport road. The airplane sustained substantial damage to the left wing and fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9943W](https://openairdocs.org/aircraft/N9943W), registered now, S/N CCX-2000-0081, built 2020 (OpenAirDocs) - Reported make and model: CCX-2000-0081 LLC CCX-2000 - Registry model: [Ccx-2000-0081 CCX-2000](https://openairdocs.org/model/ccx-2000-0081-ccx-2000) (registry code 05638YQ) (OpenAirDocs) - Registry engine: [Lycoming CC363I](https://openairdocs.org/engine/lycoming-cc363i) (registry code 41465, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: CCX-2000-0081 - Year built: 2020 - Airframe hours: 61.8 - Engines: Lycoming CC363i 186 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Da Plane LLC - Airworthiness certificate: Special, Experimental (Special) - Last inspection: March 5, 2020, 61.8 hours before - Departed: KGXT, Greeley, CO - Destination: Same as departure - Airport: KLMO, Vance Brand Airport - Equipment: Electronic primary flight display, Auto-pilot, Angle of attack indicator, ADS-B, Stall warning system ## Flight crew As NTSB recorded them.
