Overall Trends
Total, fatal, and serious accidents in the selected range.
Search investigations, review source evidence, monitor watched reports, and trace long-term patterns from one calm, data-first workspace.
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.

THE HOME BUILT ACFT WAS EQUIPPED WITH A KAWASAKI TA-440A ENG & AN UNSPECIFIED PROPELLER, BOTH OF WHICH WERE DIFFERENT THAN THE ORIGINAL PLANS CALLED FOR. THE PLT STATED THAT ON THE 1ST TEST FLT WITH THE NEW ENG & PROP COMBINATION, THE ENG RPM & THRUST WOULD NOT INCREASE SUFFICIENTLY TO CLIMB, EVEN THOUGH THE ENG HAD A HIGHER HORSE POWER RATING THAN THE ONE THAT WAS DESIGNED FOR THIS PLANE. HE TURNED AROUND & TRIED TO LAND BACK ON THE ARPT. HOWEVER, THE PLT STATED THAT THE ACFT ENCOUNTERED A DOWNDRAFT & CONTACTED THE GROUND SHORT OF THE RWY. SUBSEQUENTLY, THE ACFT WAS DAMAGED ON ROCKY TERRAIN. THE PLT REPORTED THAT THE WIND WAS FROM 220 DEG AT 5 GUSTING 10 KTS. ALSO, HE STATED THAT THE TEMP WAS 94 DEG, THE DENSITY ALT WAS ABOUT 4000 FT & THAT HE SHOULD HAVE WAITED UNTIL THE NEXT MORNING TO FLY THE TEST FLT WHEN THE AIR WAS COOL.
