Aviation safety in North America

Inclusion criterion. Commercial-aviation accidents and serious incidents involving Part 121 (scheduled airline), Part 135 (commuter and on-demand), and Part 91 corporate operators based in or investigated by the United States, Canada, and Mexico. The rolling window is the ten years preceding the most recent event in the dataset. General-aviation private-pilot accidents, military aircraft, drones, and foreign carriers operating outside North America are out of scope.

Severity tiers. Accident — the higher tier per ICAO Annex 13: substantial damage to the aircraft or a fatality. Serious Incident — a near-accident in which an accident nearly occurred. Minor incidents (the third NTSB tier) are intentionally excluded to keep the table's signal-to-noise useful.

Sources. US events are sourced from the NTSB Aviation Accident Database and the searchable case interface CAROL. Canadian events are sourced from the TSB Canada Investigation Reports under the Open Government Licence — Canada. Mexican events are sourced from AFAC's accident-investigation publications. Each row links to the official report or open investigation page.

Editorial restraint. Probable-cause statements are lifted from final reports verbatim or paraphrased tightly against the official wording; ongoing investigations show "Investigation in progress" with no speculation. Fatality and injury counts are stated as factual numbers from the official reports. There are no rankings, no editorializing, no photos of crash sites.
