  • 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.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1983-06-08.
  • API snapshot SHA-256: 5150e50ec3ef0315ec698622cab43a2413d4f808a71bbd68e4742ee4cdb697c3; retrieved 2026-09-21T06:41:34.112Z.
