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 CABIN AND COCKPIT FILLED WITH SMOKE DURING CLIMBOUT. THE PILOT DECLARED AN EMERGENCY AND LANDED WITHOUT INCIDENT. HOWEVER, DURING THE TAXI TO THE RAMP THE FLIGHT CREW STARTED THE APU AND SMOKE FILLED THE CABIN AND COCKPIT AGAIN. THE PILOT STOPPED THE AIRPLANE AND ORDERED AN EVACUATION VIA THE EMERGENCY SLIDES. THE FLIGHT ATTENDANTS STARTED THE EVACUATION AND DISCOVERED THAT THREE SLIDES WOULD NOT DEPLOY. EXAMINATION OF THE AIRPLANE DISCLOSED THAT THE NUMBER 2 AIR CYCLE MACHINE HAD OVERHEATED AND SMOKE FLOWED INTO THE AIRPLANE. ADDITIONALLY, THE GIRT BARS ON THE 3 INOPERATIVE SLIDES WERE NOT INSTALLED IN ACCORDANCE WITH STANDARD PROCEDURES.
