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.
Clifton, VA
SHORTLY AFTER LEVELING AT THE CRUISE ALTITUDE OF 2500 FT, THE PILOT NOTED A GRADUAL RPM DECREASE AND RESULTANT LOSS OF POWER. ALTITUDE COULD NOT BE MAINTAINED AND THE PILOT SELECTED A ROLLING OPEN FIELD IN WHICH TO LAND WHEN HE REALIZED THAT REACHING AN AIRPORT SEVEN MILES SOUTH WAS IMPROBABLE. DURING THE LANDING ROLL A STEEP INCLINE WAS ENCOUNTERED THAT COLLAPSED THE NOSE GEAR AND THE ACFT SLID. THE TEMPERATURE AND DEW POINT INDICATED THAT CONDITIONS WERECONDUCIVE TO THE FORMATION OF CARBURETOR ICE. THE PLT STATED THAT HE DID NOT APPLY CARB HEAT BECAUSE HE FELT THAT LIST IN THE PILOT'S OPERATING HANDBOOK DOES NOT INCLUDE THE APPLICATION OF CARB HEAT. THE ENGINE WAS LATER RUN SUCCESSFULLY IN A TEST CELL WITH NO DISCREPANCIES NOTED.
