The airplane veered to the right and the right wing subsequently collided with a post on the edge of the runway. The right wing and fuselage were substantially damaged. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. At the time of the accident, the pilot was landing the airplane on runway 9 with wind from 230° at 8 knots gusting to 15 knots. ## Sequence of events The events NTSB coded, in order, by phase of flight. The defining event best describes what happened. - [Landing-landing roll: Other weather encounter](https://openairdocs.org/ntsb-events/400) - [Landing-landing roll: Loss of control on ground](https://openairdocs.org/ntsb-events/230) (defining event) ## Aircraft - Registration: [N699X](https://openairdocs.org/aircraft/N699X), registered now, S/N CCK-2000-0087, built 2022 (OpenAirDocs) - Reported make and model: SEABOURN SCOTT R CCK-2000 - Registry model: [Seabourn Scott R CCK-2000](https://openairdocs.org/model/seabourn-scott-r-cck-2000) (registry code 056408W) (OpenAirDocs) - Registry engine: [Lycoming YIO-360 EXP](https://openairdocs.org/engine/lycoming-yio-360-exp) (registry code 41710, reciprocating) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: CCK-2000-0087 - Year built: 2022 - Airframe hours: 10 - Engines: Lycoming CC363I-YIO-360-EXP 186 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Condition, September 1, 2022, 10 hours before - Departed: VCB, Vacaville, CA - Destination: CN13, Clarksburg, CA - Airport: CN13, Borges Clarkburg Airport, runway 9, 2,200 × 80 ft, grass/turf - Equipment: ADS-B, Stall warning system, Angle of attack indicator, Auto-pilot, Electronic multifunction display ## Flight crew As NTSB recorded them.
