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.

The pilot reported that during takeoff from a remote beach site, soft sand pulled the airplane to the left, so she aborted the takeoff and repositioned for a second attempt. During the second takeoff attempt, just prior to rotation, the airplane’s right wheel contacted the water, which pivoted the airplane to the right, and it nosed down into the shallow water. The right wing sustained substantial damage. The pilot reported that there were no pre-accident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
