The NTSB's narrative final · quoted from the NTSB record
The student pilot reported that during the takeoff ground roll on the runway, about 35 knots, the pilot moved the control stick slightly forward from the aft position and allowed the nose wheel to rise slightly above the surface, while he increased the throttle setting to 75%. As the gyroplane reached about 70 knots, it started to veer to the left and shudder, so the pilot slightly decreased the throttle setting. As the pilot approached the end of the runway, the pilot increased the throttle setting and maintained the control stick position. Subsequently, the gyroplane pitched up and rolled onto its right side. The gyroplane impacted the ground and slid to a stop on its right side within the runway safety area. The gyroplane sustained substantial damage to the drivetrain. The pilot reported that there were no preaccident mechanical failures or malfunctions with the gyroplane that would have precluded normal operation. The pilot added that during the takeoff, he should have held the aft position of the control stick to maintain the rotor RPM or aborted the takeoff earlier.

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 WPR25LA222.
