The defining event best describes what happened. - [Landing: Landing area overshoot](https://openairdocs.org/ntsb-events/380) (defining event); cases with it: [Thomas J Spencer RV-10, 1 case](https://openairdocs.org/ntsb-events/380/sequence.md?model=05637PJ), [All aircraft, 400 cases](https://openairdocs.org/ntsb-events/380/sequence.md) ## Analysis The pilot of the airplane reported that, while on final approach to the runway, the wind shifted, causing him to land with a tailwind. The pilot realized that he wouldn’t be able to stop the airplane on the runway, but believed the fence at the end of the runway prevented him from safely performing a go-around. The airplane overran the departure end of the runway, striking the fence and an occupied vehicle before impacting terrain. The airplane sustained substantial damage to the wings and empennage. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N90VT](https://openairdocs.org/deregistered/N90VT-2024-08-05), registration cancelled 2024-08-05, S/N 41675, built 2019 (OpenAirDocs) - Reported make and model: THOMAS J SPENCER RV-10 - Registry model: [Thomas J Spencer RV-10](https://openairdocs.org/model/thomas-j-spencer-rv-10) (registry code 05637PJ) (OpenAirDocs) - Registry engine: [Lycoming IO-540 series](https://openairdocs.org/engine/lycoming-io-540-series) (registry code 41585, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 41675 - Year built: 2019 - Airframe hours: 303 - Engines: Lycoming IO-540 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, October 24, 2023 - Departed: 1W1, Camas, WA - Destination: Same as departure - Flight plan: IFR - Airport: S43, Harvey Field Airport, runway 15L, 2,672 × 36 ft, asphalt - Equipment: Auto-pilot, Electronic flight bag or handheld device, Electronic multifunction display, Electronic primary flight display, Onboard weather, Satellite tracking device, Stall warning system, ADS-B, Angle of attack indicator ## 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.
