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 a steep turn maneuver, the airplane pitched down and accelerated rapidly. The pilot stated that the airplane exceeded the never-exceed speed (VNE) and encountered aerodynamic buffeting, which resulted in the in-flight separation of the outboard portion of the left flaperon and substantial damage to the left wing. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operation.
NTSB Probable Cause
The pilot’s exceedance of the airplane’s never-exceed speed (VNE) during maneuvering, which resulted in the in-flight separation of the left flaperon.
