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, who was landing in calm winds, allowed the nose gear to contact the runway hard during a touch-and-go landing. When the airplane bounced back into the air, the pilot executed a go-around and then made a full-stop landing in order to check the airplane for possible damage. That inspection revealed that the impact had resulted in multiple wrinkles in the firewall.
