  • 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 1984-06-25.
  • API snapshot SHA-256: 7973835dda89e98c6260d7d234753f19501d27dca0c64c4a179a084822344278; retrieved 2026-09-23T20:14:21.960Z.
