  • 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 1986-07-27.
  • API snapshot SHA-256: c537f229a60f1ee0557e09da34121b05df6576de56554ccc78d228e43d50934f; retrieved 2026-09-18T14:20:02.479Z.
