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.

NTSB Probable Cause
THE FAILURE OF THE LOCAL CONTROLLER TO PROVIDE ADEQUATE TRAFFIC ADVISORIES TO N7510H, THE LOCAL CONTROLLER'S IMPROPER CLEARANCE TO N7510H TO DESCEND THROUGH THE TRAFFIC PATTERN, AND THE FAILURE OF THE PILOTS OF BOTH AIRCRAFT TO SEE AND AVOID EACH OTHER. FACTORS WHICH CONTRIBUTED TO THE ACCIDENT WERE THE LOCAL CONTROLLER'S WORKLOAD AND THE EFFECT OF SUNGLARE ON THE PILOT OF N48977.
