Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

WPR10CA428
The pilot reported that during the takeoff roll, at the time of rotation, the canopy started to slide rearward. As the pilot attempted to close the canopy the airplane nosed over and the propeller struck the runway, substantially damaging the airplane’s firewall. The pilot further reported that the accident could have been prevented by conducting a “second check of proper canopy closure prior to entering [the] runway.” The pilot reported no mechanical failures or malfunctions with the airframe or engine prior to the accident.
NTSB Probable Cause
The pilot’s inadequate pretakeoff checks and failure to maintain control during the takeoff roll. Contributing to the accident was the pilot’s diverted attention due to the open canopy.
