The airplane came to rest upside down which resulted in substantial damage to the wing, vertical stabilizer, and rudder. The flight instructor reported he was holding appropriate flight control inputs for the wind at the time the accident occurred. He reported further that there were no mechanical failures or malfunctions with the airplane that would have precluded normal operations. ## Aircraft - Registration: [N20095](https://openairdocs.org/aircraft/N20095), registered now, S/N 17261005, built 1972 (OpenAirDocs) - Reported make and model: CESSNA 172M - Registry model: [Cessna 172M](https://openairdocs.org/model/cessna-172m) (registry code 2072418) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17261005 - Year built: 1972 - Airframe hours: 17374.3 - Engines: Lycoming O-320-E2D 150 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Registered owner: WingsLeasing LLC - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: 100 hour, April 5, 2024 - Destination: Same as departure - Airport: DPA, Dupage, runway 02L/20R, 7,571 × 150 ft, concrete - Equipment: Electronic flight bag or handheld device, ADS-B ## Flight crew As NTSB recorded them.
