During takeoff, the pilot receiving instruction applied excessive right rudder and the airplane went to the right, he relieved the right rudder, and the airplane veered to the left, traveling diagonally across the runway. The flight instructor applied aft pressure on the stick to get the airplane airborne, simultaneously the pilot receiving instruction reduced the throttle to idle. The airplane bounced and impacted terrain and nosed over. The airplane sustained substantial damage to the fuselage, empennage and wings. The pilot reported no pre-impact mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N188CG](https://openairdocs.org/aircraft/N188CG), registered now, S/N KA18184375, built 2021 (OpenAirDocs) - Reported make and model: CORY GREEN KITFOX SERIES 7 STI - Registry model: [Cory Green KITFOX SERIES 7 STI](https://openairdocs.org/model/cory-green-kitfox-series-7-sti) (registry code 05639YI) (OpenAirDocs) - Registry engine: [Rotax 912ULS series](https://openairdocs.org/engine/rotax-912uls-series) (registry code 55572, 4 cycle) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: KA18184375 - Year built: 2021 - Airframe hours: 70.7 - Engines: Rotax 912ULS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Bracher Farms - Registered owner: Bracher Farms - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, January 23, 2024, 20 hours before - Departed: KHRI, Hermiston, OR - Destination: Same as departure - Airport: KHRI, Hermiston Municipal Airport, runway 23, 451 × 75 ft, asphalt - Equipment: Handheld GPS, ADS-B, Electronic primary flight display ## Flight crew As NTSB recorded them.
