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.

PENAIR FLIGHT 4266 WAS CLEARED FOR A LOCALIZER DME APPROACH TO RUNWAY 19. THE AIRPLANE BROKE OUT OF THE CLOUDS AT 800 FEET MSL AT 4.8 DME FROM THE AIRPORT. THE CREW IMMEDIATELY SAW AN AIRPLANE DIRECTLY IN FRONT, AND AFTER EVASIVE ACTION THE AIRPLANES PASSED WITHIN 100 FEET OF EACH OTHER. THE SPECIAL WEATHER OBSERVATION, TAKEN ONE MINUTE PRIOR TO THE NEAR MID AIR BUT NOT YET TRANSMITTED, SHOWED THE CONTROL ZONE BELOW VISUAL METEOROLOGICAL CONDITIONS. HOWEVER, THE PREVIOUS HOURLY OBSERVATION, AND THE MOST CURRENT TRANSMITTED OBSERVATION, SHOWED THAT THE CONTROL ZONE WAS UNDER VISUAL METEOROLOGICAL CONDITIONS.
NTSB Probable Cause
THE VISUAL LOOKOUT THAT WAS NOT MAINTAINED BY THE PILOT OF THE OTHER AIRPLANE. FACTORS WERE THE DRIZZLE AND FOG AND THE IMPOSSIBILITY OF UPDATING THE RECORDED WEATHER INFORMATION BY ATC PERSONNEL.
