  • 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 1984-06-28.
  • API snapshot SHA-256: 611378c6fe6752cb52ff684cdccd71d9a9ba45af547974bbd55d4188390f4228; retrieved 2026-09-18T20:39:30.732Z.
