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 PLT SHUT DOWN THE ENG & ASKED FOR RADAR VECTORS TO JOHNSON COUNTY EXECUTIVE ARPT. THE FIRE WENT OUT AT 21,000 FT & THE ACFT LANDED WITHOUT FURTHER INCIDENT. THERE WAS SEVERE BUCKLING OF THE ENG FIREWALL DUE TO THE INTENSE HEAT GENERATED BY THE ENG FIRE. THE TURBO-CHARGER EXHAUST CONNECTING TUBE HAD SEPARATED FROM THE EXHAUST SYSTEM. THE TURBO/ EXHAUST TAILPIPE COUPLING, PN 78012, WAS OUT OF CENTERLINE ALIGNMENT BY 1.043 INCHES. INSTALLATION OF THIS COMPONENT WITHOUT PROPER ALIGNMENT WOULD PROHIBIT FULL DEPTH ENGAGEMENT OF THE TUBE WITH THE CONNECTING EXHAUST SYSTEM COMPONENTS.
