- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- No bulk values were replaced by the NTSB case API.
- The date is the UTC date the NTSB stores; the local time zone is not recorded, so the local date may differ by a day.
