He added that, during the landing roll, the airplane "started to veer off the runway," so he applied power to abort the landing and that, during the aborted landing, he "pulled back" on the yoke. The airplane then aerodynamically stalled and impacted grass left of the runway and then nosed over. The fuselage, left wing, and vertical stabilizer sustained substantial damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Factual narrative The pilot reported that the airplane was low and he felt "rushed" during final approach. He further reported that during the landing roll the airplane "started to veer off the runway," so he applied power to abort the landing. During the aborted landing, the pilot reported that he "pulled back" on the yoke; the airplane aerodynamically stalled and impacted on the grass to the left of the runway and nosed over. The fuselage, left wing, and vertical stabilizer sustained substantial damage. The pilot did not report any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N4853U](https://openairdocs.org/deregistered/N4853U-2017-03-13), registration cancelled 2017-03-13, S/N 21064824, built 1984 (OpenAirDocs) - Reported make and model: CESSNA T210 (N) - Registry model: [Cessna T210N](https://openairdocs.org/model/cessna-t210n) (registry code 2073456) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21064824 - Year built: 1984 - Airframe hours: 5505 - Engines: Continental TSIO-520-R 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 4, 2016 - Departed: SAF, SANTA FE, NM - Destination: FNL, Loveland, CO - Flight plan: IFR - Airport: FNL, Fort Collins-Loveland Muni, runway 15, 8,500 × 100 ft, asphalt - Equipment: Electronic flight bag or handheld device, Auto-pilot, ADS-B, Stall warning system, Onboard weather, Handheld GPS, Electronic primary flight display, Electronic multifunction display ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
