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 local date, which is the same as the UTC date the NTSB stores.
