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 pilot planned to land near a restaurant for lunch with three passengers. He over flew the landing area and then set up for a “gradual and slow” approach. When the helicopter touched down, he felt the tail drop backwards. The pilot stated that he compensated by adding collective and forward cyclic which inadvertently induced a dynamic rollover. He added that a gusty tailwind prevailed at the time of the landing. The helicopter sustained damage to the main rotor blades, the main rotor transmission mount, fuselage, and horizontal stabilizers. The pilot reported that there were no mechanical malfunctions or failures associated with the helicopter before the accident.
