The flight instructor directed the student pilot to pitch down as he applied forward pressure on the yoke. The airplane remained in a nose high attitude and yawed to the left. The flight instructor verbalized “my controls” as the airplane then turned to the right and the pitch increased. The airplane came to rest upright on the edge of the runway. The landing gear collapsed upon impact with the ground which resulted in substantial damage to the engine mount and firewall. The flight instructor stated that there were no preimpact mechanical malfunctions or failures that would have precluded normal operations. ## Aircraft - Registration: [N594M](https://openairdocs.org/aircraft/N594M), registered now, S/N 2595, built 2020 (OpenAirDocs) - Reported make and model: CIRRUS DESIGN CORP SR20 - Registry model: [Cirrus Design SR20](https://openairdocs.org/model/cirrus-design-sr20) (registry code 2130000) (OpenAirDocs) - Registry engine: [Lycoming IO-390-C3B6](https://openairdocs.org/engine/lycoming-io-390-c3b6) (registry code 42710, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 2595 - Year built: 2020 - Airframe hours: 1709.8 - Engines: Lycoming IO-390 215 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Mistwood Air 1 LLC - Registered owner: Mistwood Air 1 LLC - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, March 22, 2024 - Destination: Same as departure - Flight plan: VFR - Airport: SUS, Spirit Of St Louis, runway 26R, 5,000 × 75 ft, asphalt - Equipment: Electronic multifunction display, Auto-pilot, Airframe parachute, ADS-B, Stall warning system, Electronic primary flight display ## Flight crew As NTSB recorded them.
