- NTSB record (all air medical)
- In both
The two records answer different questions. The NTSB counts every U.S. air medical accident and the incidents the rules require, whether or not a program told anyone else. CONCERN recorded what programs chose to share, and it held many events the rules never asked anyone to report. The NTSB series is drawn from the AMSN Accident Database (version 2026-10-19, through 2025) for every year and does not change with the filters; select a year to filter the page.

Which events did the rules cover?
Research coding from the bulletin text, not NTSB determinations. Most CONCERN events fall in classes that no rule required anyone to report. The 2010 amendment added helicopter rotor blade damage that requires major repair or replacement, including ground damage, to the serious incidents that must be reported.

What is shown
The fields the Air Medical Journal printed in its CONCERN Network section in 2006: date, program and city, vendor, weather, aircraft, who was aboard by role, injuries, and the description.
Tail numbers, report sources, and the names of individuals are withheld. Coded fields show the light condition rather than the clock time; the bulletin text keeps times as reported.
How it is coded
Each bulletin is kept as distributed. Event type, phase, injury, damage, and reporting status are research coding by Russell Griffin, PhD, MBA. They are not part of the NTSB record and may contain errors.
Where bulletins disagreed or a later bulletin corrected an earlier one, each change is logged with its basis.
About the archive
The archive is built on the bulletins kept from about 2000 by David Kearns, MS, RN, CFRN, CONCERN Coordinator. Programs shared these reports with one another so others could learn from them. The archive keeps them as they were distributed.
Follow-ups, corrections, and duplicate distributions are folded into the event they describe. Notices, memorials, and test messages are kept in the archive but are not shown as events.
