The pilot was unable to maintain directional control and the airplane departed the left side of the runway and nosed over in a grassy area adjacent to the runway. The airplane sustained substantial damage to the engine mount, firewall, left wing, vertical stabilizer, and rudder. An examination of the airplane revealed that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N6837F](https://openairdocs.org/aircraft/N6837F), registered now, S/N 15063437, built 1966 (OpenAirDocs) - Reported make and model: CESSNA 150F - Registry model: [Cessna 150F](https://openairdocs.org/model/cessna-150f) (registry code 2071814) (OpenAirDocs) - Registry engine: [Continental 0-200 series](https://openairdocs.org/engine/continental-0-200-series) (registry code 17020, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 15063437 - Year built: 1966 - Airframe hours: 2848.6 - Engines: Continental O-200-A 100 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Skyberjet LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, January 16, 2023, 11.9 hours before - Departed: F46, Rockwall, TX - Destination: Same as departure - Airport: KSWI, Sherman Municipal Airport, runway 16, 4,000 × 75 ft, asphalt - Equipment: Electronic flight bag or handheld device, ADS-B, Handheld GPS ## Flight crew As NTSB recorded them.
