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 TRANSCRIPT REVEALED THAT THE PLT WAS CLEARED FOR AN ILS RWY 30 APCH APPROXIMATELY 2 MI FROM THE OUTER MARKER. THE WX GIVEN TO THE PLT AT THAT TIME WAS INDEFINITE CEILING ZERO, SKY OBSCURED & VISIBILITY ZERO WITH FOG. THE PLT STATED AN INSTRUMENT APCH WAS PLANNED BUT A CLEAR AREA WAS OBSERVED SOUTH OF THE ARPT. THE CLEAR AREA WAS ENTERED & AN ATTEMPT MADE TO FLY TO THE ARPT BENEATH THE FOG. THE ACFT STRUCK A UTILITY POLE WEST OF THE RWY 30 LOCALIZER COURSE, CIRCLED LEFT & CRASHED. THE ACFT'S GLIDE SLOPE RECEIVER SENSITIVITY WAS FOUND TO BE BELOW THE MANUFACTURER'S SPECIFICATIONS, WHICH WOULD HAVE RESULTED IN A GLIDE SLOPE "OFF" INDICATION IN THE COCKPIT.
