The NTSB's narrative preliminary · quoted from the NTSB record
On June 2, 2026, at 0837 central daylight time, an AutoGyro Cavalon gyroplane, N113CX, was substantially damaged when it was involved in an accident near Coffeyville, Kansas. The pilot was not injured. The gyroplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot, he was on his second solo flight of the day. During takeoff, about 10 to 30 ft above the runway, the gyroplane started to shake violently and roll to the left. The pilot attempted to correct the roll with full right cyclic and rudder but was unable to regain control. The gyroplane impacted terrain, bounced, and rolled several times across the ground before coming to rest on its left side resulting in substantial damage to the empennage, fuselage, and main rotors. The gyroplane was recovered to a secure facility for further examination.

About this page
Everything above comes from the NTSB's public accident database: the narrative, probable cause and findings are the NTSB's own words, and the coded tables behind its report (pilot, aircraft, flight, weather, injuries, sequence of events) are written out in plain English. Pilots' ages, home towns and medical details are left out on purpose. The documents and photographs are the NTSB's docket, the folder of records gathered during the investigation, shown as the NTSB released them (the NTSB redacts some personal details first) and listed under the NTSB's own titles. This site's own text never names pilots, passengers or anyone else involved. A preliminary report describes what is known soon after the event and can change; the final report, with the probable cause, usually follows one to two years later and this page is refreshed when it does. Case number CEN26LA217.
