The NTSB's narrative final · quoted from the NTSB record
The pilot said he began the takeoff roll and at 25 to 30 mph, he raised the tail. The airplane 'immediately jerked to the left.' The pilot corrected with right rudder, overshot the runway centerline, and the airplane 'jerked to the left' again. The pilot aborted the takeoff, but the airplane skidded off the right side of the runway. The right landing gear collapsed, and the airplane nosed over. In an interview with the pilot, he said he 'over-corrected' and the airplane began 'fish tailing.' The right wing then contacted the ground as the aircraft swerved to the left and the airplane nosed over. The pilot said he may have inadvertently stepped on a brake, causing the loss of control.

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 docket at the NTSB holds the report as a PDF and the investigation's photographs and documents. This site 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 FTW98LA046.
