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.

He further reported that, after separating the wing skins opened and floated behind the UAS as it rolled right, spun, and impacted terrain. Substantial damage was identified to the entire UAS, to include the fuselage, both wings, and empennage Postaccident examination by a Federal Aviation Administration inspector revealed that the right-wing skin had delaminated/separated from the wing spar consistent with a failed bond between the wing skin and wing spar.
