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 INHERENT LIMITATIONS OF THE SEE-AND-AVOID CONCEPT OF SEPARATION OF AIRCRAFT OPERATING UNDER VISUAL FLIGHT RULES THAT PRECLUDED THE PILOTS OF THE MU-2 AND THE PA-32 FROM RECOGNIZING A COLLISION HAZARD AND TAKING ACTIONS TO AVOID THE MIDAIR COLLISION. CONTRIBUTING TO THE CAUSE OF THE ACCIDENT WAS THE FAILURE OF THE MU-2 PILOT TO USE ALL THE AIR TRAFFIC CONTROL SERVICES AVAILABLE BY NOT ACTIVATING HIS INSTRUMENT FLIGHT RULES FLIGHT PLAN BEFORE TAKEOFF. ALSO CONTRIBUTING TO THE CAUSE OF THE ACCIDENT WAS THE FAILURE OF BOTH PILOTS TO FOLLOW RECOMMENDED TRAFFIC PATTERN PROCEDURES, AS RECOMMENDED IN THE AIRMAN'S INFORMATION MANUAL, FOR AIRPORT ARRIVALS AND DEPARTURES.
