The airplane came to rest upright inside the windsocks segmented circle. The airplane sustained substantial damage to the right wing, aft fuselage, right horizontal stabilizer, and right elevator. The student pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N17274](https://openairdocs.org/aircraft/N17274), registered now, S/N 17280353, built 1998 (OpenAirDocs) - Reported make and model: CESSNA 172R - Registry model: [Cessna 172R](https://openairdocs.org/model/cessna-172r) (registry code 2072401) (OpenAirDocs) - Registry engine: [Lycoming I0360 SER A&C](https://openairdocs.org/engine/lycoming-i0360-ser-a-c) (registry code 41511, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17280353 - Year built: 1998 - Airframe hours: 6922.5 - Engines: Lycoming IO-360-L2A reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Iasco Flight Training Inc - Registered owner: Iasco Flight Training Inc - Airworthiness certificate: Standard, Utility; Standard, Normal - Last inspection: 100 hour, August 30, 2023 - Airport: RDD, Redding Muni, runway 34, 7,003 × 150 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
