Fast key and full-text search with live filters, watches, and precise metadata.
Use quotes for exact phrase matches (for example "fuel selector valve").
Track fatal and non-fatal accident patterns across Part 91, Part 135, and Part 121 operations.
Major cases, deep-report coverage, and investigation media across decades of NTSB history.
Move quickly by aircraft, airport, operator, and time with indexes built for research, not wandering.
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.

AT THE END OF A PLEASURE CROSS COUNTRY FLT, WHILE ON LONG FINAL TO THE RWY, THE PLT HAD TO ADD PWR TO COMPENSATE FOR A CROSSWIND. PRIOR TO REACHING SHORT FINAL THE PLT HAD REDUCED PWR AGAIN. UPON REACHING THE THRESHOLD, THE ACFT WAS APRX 300 FT AGL. THE PLT DECIDED TO GO-AROUND. PWR WAS RAPIDLY ADDED AND THE CARBURETOR HEAT TURNED OFF. THE ENGINE AT THIS TIME ONLY DEVELOPED PARTIAL PWR. THE PLT THEN ADDED CARBURETOR HEAT AGAIN. THE ENGINE, STILL NOT DEVELOPING SUFFICIENT PWR TO MAINTAIN ALTITUDE WAS DESCENDING AT 50-100 FPM. THE PLT THEN LANDED THE ACFT BEYOND MIDFIELD AND BOUNCED SEVERAL TIMES BEFORE RUNNING OFF THE RUNWAY AND COLLIDED WITH THE TERRAIN.
