The defining event best describes what happened. - [Takeoff: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event); cases with it: [Cessna 172, 14 cases](https://openairdocs.org/ntsb-events/230/sequence.md?model=2072402), [All aircraft, 4,585 cases](https://openairdocs.org/ntsb-events/230/sequence.md) ## Analysis The pilot reported that during the takeoff roll, the airplane drifted left so he applied right rudder, but the rudder pedals were “jammed” by the passenger in the left seat. The pilot was unable to maintain directional control. The airplane departed the left side of the runway and continued through a culvert, which resulted in substantial damage to the fuselage. The pilot reported no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N6205E](https://openairdocs.org/aircraft/N6205E), registered now, S/N 46305, built 1958 (OpenAirDocs) - Reported make and model: CESSNA 172 - Registry model: [Cessna 172](https://openairdocs.org/model/cessna-172) (registry code 2072402) (OpenAirDocs) - Registry engine: [Continental 0-300 series](https://openairdocs.org/engine/continental-0-300-series) (registry code 17022, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 46305 - Year built: 1958 - Airframe hours: 2213 - Engines: Continental O-300 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 1, 2023, 30 hours before - Departed: K50, Derby, KS - Destination: K50, Derby, KS - Airport: K50, Cook Airfield, runway 35, 3,472 × 40 ft, asphalt - Equipment: Stall warning system, ADS-B, Electronic primary flight display ## Flight crew As NTSB recorded them.
