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 experimental amateur-built airplane sustained substantial damage on impact with a fence and terrain. The pilot suspected engine problems on takeoff and elected to return to the departure airport. The pilot's accident report stated, "Pilot has flown over the old 4' fence many times over in the last 20 years, but did not realize the new 6' fence was out of sight and at this distance the pilot needs to lower the tail for a 3 point landing." An examination of the wreckage revealed no pre-impact anomalies.
NTSB Probable Cause
The pilot's failure to maintain the proper glidepath and clearance from a fence while on final approach.
