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.

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.
Cottonwood, ID
The pilot reported that during the takeoff ground roll from the private grass airstrip, the airplane’s left main tire and the tailwheel struck a rock that was partially hidden by the tall grass. The pilot continued the takeoff, proceeded to the destination airport, and landed uneventfully. After landing, the rudder was found substantially damaged. The pilot reported no preimpact mechanical failures or malfunctions with the airplane or engine that would have precluded normal operation.
