As the student pilot was landing the airplane at their home airport, the touchdown was normal, but the airplane immediately veered left. The flight instructor took control of the airplane and attempted to correct, but the airplane continued off the left side of the runway. The left wing struck a runway sign, resulting substantial damage to the left wing, and the airplane came to rest upright in a grass area off the left side of the runway. Examination of the wreckage by a mechanic and a Federal Aviation Administration inspector revealed a flat spot and gashes on the left main landing gear tire, consistent with the tire being flat upon touchdown. ## Aircraft - Registration: [N241MU](https://openairdocs.org/aircraft/N241MU), registered now, S/N 10052, built 2024 (OpenAirDocs) - Reported make and model: CIRRUS DESIGN CORP SR20 - Registry model: [Cirrus Design SR20](https://openairdocs.org/model/cirrus-design-sr20) (registry code 2130000) (OpenAirDocs) - Registry engine: [Lycoming IO-390-C3B6](https://openairdocs.org/engine/lycoming-io-390-c3b6) (registry code 42710, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 10052 - Year built: 2024 - Airframe hours: 508 - Engines: Lycoming IO-390-C3B6 215 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Marshall University - Registered owner: Marshall University - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, August 22, 2025, 12 hours before - Departed: PKB, Parkersburg, WV - Destination: Same as departure - Airport: CRW, West Virginia Intl Yeager, runway 23, 6,715 × 150 ft, asphalt - Equipment: ADS-B, Airframe parachute, Angle of attack indicator, Auto-pilot, Data recorder, Electronic flight bag or handheld device, Electronic multifunction display, Electronic primary flight display, Onboard weather, Stall warning system ## Flight crew As NTSB recorded them.
