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 PILOT SAID THE FLIGHT WAS NORMAL UNTIL ESTABLISHED ON THE VOR APPROACH. AFTER THE AIRCRAFT COMPLETED THE PROCEDURE TURN AND WAS INBOUND TO THE VOR THE PILOT NOTICED THAT THE AIRCRAFT WAS DESCENDING THROUGH ABOUT 1,300 FEET MSL (1,000 FEET AGL) AND THAT THE DESCENT RATE WAS STABALIZED AND WAS SUFFICIENT TO MAKE THE CROSSING RESTRICTION AT THE VOR. THE PILOT STATED THAT SHE THEN SCANNED THE VOR NAVIGATION HEADS 'FOR A FEW SECONDS' TO CROSS CHECK THE AIRCRAFT POSITION ON THE APPROACH COURSE RADIAL. SHORTLY THEREAFTER, THE AIRCRAFT FLEW INTO LEVEL TERRAIN ABOUT 1.5 MILES SOUTH OF THE AIRPORT.
