He applied right rudder and added brake to counteract the drift unsuccessfully. The airplane continued to swerve left, and the right main landing gear separated from the plane which resulted in substantial damage to the fuselage and right wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N9623Q](https://openairdocs.org/aircraft/N9623Q), registered now, S/N 22840 (OpenAirDocs) - Reported make and model: CESSNA 305A - Registry model: [Cessna 305A](https://openairdocs.org/model/cessna-305a) (registry code 2074002) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 22840 - Year built: 1951 - Airframe hours: 10149 - Engines: Continental O-470-11B 213 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: OV-10 Bronco Association Inc. - Airworthiness certificate: Standard, Normal - Last inspection: Annual, July 18, 2024 - Departed: KCWI, Clinton, IA - Destination: KDLL, Baraboo, WI - Airport: DLL, Baraboo/Wisconsin Dells, runway 19, 5,010 × 75 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
