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.
Big Bear, CA
ACCORDING TO THE PLT, AFTER A RUNUP, DURING WHICH THE MIXTURE WAS 'LEANED', THE ACFT DEPARTED RWY 25 AT BIG BEAR AIRPORT. HE STATED THAT THE NOSE OF THE ACFT WAS LOWERED TO 'GAIN 80 KTS IAS,' AND THAT THE ACFT 'CLIMBED TO APPROXIMATELY 150 TO 200 FT ABOVE THE LAKE AND WOULD CLIMB NO HIGHER.' THE ACFT THEN 'BEGAN A GRADUAL DESCENT,' AND STRUCK THE WATER AT '60 KTS IN WHAT SEEMED LIKE A LEVEL ATTITUDE.' INVESTIGATION REVEALED THE ACFT WAS AT LEAST 294 LBS OVER GROSS WT. THE DENSITY ALTITUDE WAS ALSO COMPUTED TO BE 8352 FT WHEN USING 60 DEG F AS A VALVE. THE RECORDED TEMP 15 NM AWAY WAS 86 DEG F. NO PRE-IMPACT DISCREPANCIES WERE FOUND DURING THE EXAMINATION OF ACFT WRECKAGE OR THE SUBSEQUENT ENG TEST.
