The pilot attempted to correct with opposite rudder; however, the airplane continued off the runway and hit a taxiway sign with the left wing and landing gear struts. The airplane sustained substantial damage to the left-wing strut. The pilot reported to the duty officer that there were no preimpact mechanical malfunctions or failures that would have precluded normal operation. ## Aircraft - Registration: [N734NJ](https://openairdocs.org/aircraft/N734NJ), registered now, S/N 17268981, built 1977 (OpenAirDocs) - Reported make and model: CESSNA 172N - Registry model: [Cessna 172N](https://openairdocs.org/model/cessna-172n) (registry code 2072434) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17268981 - Year built: 1977 - Engines: Lycoming O-360-E2D 160 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Flyright Aviation Inc - Registered owner: Flyright Aviation Inc - Airworthiness certificate: Standard, Normal - Last inspection: March 14, 2023 - Departed: U08, Overton, NV - Destination: KVGT, Las Vegas, NV - Airport: KVGT, North Las Vegas, runway 30R, 4,199 × 75 ft, asphalt - Equipment: ADS-B ## Flight crew As NTSB recorded them.
