During the takeoff roll, the aircraft veered left and then right, then rolled on its side and exited the runway. According to the flight instructor, the pilot receiving instruction made “reverse command” control inputs which led to side-to-side oscillations, which progressed without correction from the flight instructor. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N976BG](https://openairdocs.org/aircraft/N976BG), registered now, S/N 000620, built 2017 (OpenAirDocs) - Reported make and model: EVOLUTION AIRCRAFT INC REVO - Registry model: [Evolution REVO](https://openairdocs.org/model/evolution-revo) (registry code 060009B) (OpenAirDocs) - Registry engine: [Rotax 912 IS series](https://openairdocs.org/engine/rotax-912-is-series) (registry code 55593, 4 cycle) (OpenAirDocs) - Category: Weight-shift - Serial number: 000620 - Year built: 2017 - Airframe hours: 427 - Engines: ROTAX 912 IS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Ultimate Flight, LLC - Registered owner: Ultimate Flight, LLC - Airworthiness certificate: Special, Special light-sport (Special) - Last inspection: 100 hour, September 12, 2023, 27 hours before - Destination: Same as departure - Airport: CXP, Carson City, runway 27, 6,101 × 75 ft, asphalt - Equipment: ADS-B, Airframe parachute, Electronic multifunction display ## Flight crew As NTSB recorded them.
