The airplane departed the left side of the runway and the pilot applied the brakes and reduced engine power. The airplane subsequently struck a culvert, the landing gear partially collapsed, and the airplane’s firewall was substantially damaged. The pilot reported that there were no preaccident mechanical malfunctions or failures of the airplane that would have precluded normal operation. ## Aircraft - Registration: [N320CA](https://openairdocs.org/aircraft/N320CA), registered now, S/N 0822, built 2014 (OpenAirDocs) - Reported make and model: CIRRUS DESIGN CORP SR22T - Registry model: [Cirrus Design SR22T](https://openairdocs.org/model/cirrus-design-sr22t) (registry code 2130004) (OpenAirDocs) - Registry engine: [Continental TSIO-550-K](https://openairdocs.org/engine/continental-tsio-550-k) (registry code 17410, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 0822 - Year built: 2014 - Engines: Continental TSIO550K1B 315 horsepower reciprocating - Damage: Substantial damage - Flight: Business, Part 91 - Operator: Armstrong Resource Management Corp - Registered owner: Armstrong Resource Management Corp - Airworthiness certificate: Standard, Normal - Departed: DKX, Knoxville, TN - Destination: CCO, Newman, GA - Flight plan: IFR - Airport: DKX, Knoxville Downtown Island, runway 8, 3,499 × 75 ft, asphalt - Equipment: Auto-pilot, Electronic multifunction display, Electronic primary flight display, Onboard weather, Stall warning system, ADS-B, Airframe parachute, Angle of attack indicator ## Flight crew As NTSB recorded them.
