Source notes (4)
- 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, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2010-07-15.
- API snapshot SHA-256: 22d62ca6bdadcd20b0886a1bab1fca38f2495138116809a3769961ec3064e351; retrieved 2026-09-15T14:43:17.434Z.
