What you can access after approval

Every chart and map responds to a shared set of filters, including year, phase of flight, weather, aircraft, operator, and more than 20 other fields. Any event can be opened to view its NTSB record and research coding.

Preview of the Overview tab: a filter panel beside summary tiles, an events-by-year bar chart, and a phase-of-flight chart. — **Overview.** Summary tiles and charts that redraw as you filter.

Preview of the Map tab: event locations plotted over U.S. state outlines, fatal and non-fatal events in two shades of blue. — **Map.** NTSB positions over state outlines. Click a point to open the record.

Preview images from the current version, with no filters applied.

The AMSARC Accident Database is available to approved users, including air medical crews and leaders, safety and quality staff, researchers, students, and others with a stated purpose. Each registration is reviewed by a person. Approved users receive a personal access link by email.

Several fields in this database were added through research coding by Russell Griffin, PhD, MBA. These fields are not part of the NTSB accident record and do not represent NTSB findings. Errors are possible. If you find one, or have questions about the coding, email russell.griffin@amsarc.com. The database is for research, safety, and educational use and is not to be redistributed.
