During the takeoff roll, the student pilot pitched the nose up to 15° then lowered it to 5° upon request of the instructor. As the takeoff roll continued, the student abruptly applied right rudder and again increased the pitch attitude. The airplane veered to the right and became airborne off the right side of the runway. The instructor took control of the airplane as it began to stall about 20 ft. above ground level. The airplane bounced and the propeller struck the ground, then it porpoised, and came to rest in a field about 1,000 ft. from the runway. The landing gear collapsed, and the elevator sustained substantial damage. The flight instructor reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N133LS](https://openairdocs.org/aircraft/N133LS), registered now, S/N 217, built 2007 (OpenAirDocs) - Reported make and model: REMOS AIRCRAFT GMBH G-3/600 - Registry model: [Remos G-3/600](https://openairdocs.org/model/remos-g-3-600) (registry code 060004I) (OpenAirDocs) - Registry engine: [Rotax 912ULS series](https://openairdocs.org/engine/rotax-912uls-series) (registry code 55572, 4 cycle) (OpenAirDocs) - Category: Airplane - Serial number: 217 - Year built: 2007 - Airframe hours: 3690 - Engines: Rotax 912ULS 100 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Simply Fly - Registered owner: Lsa-Midwest LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, April 9, 2023, 49.2 hours before - Departed: ARR, Sugar Grove, IL - Destination: IKK, Kankakee, IL - Airport: ARR, Aurora Municipal Airport, runway 27, 6,501 × 100 ft, concrete - Equipment: Electronic multifunction display, Angle of attack indicator, ADS-B, Electronic primary flight display ## Flight crew As NTSB recorded them.
