NTSB narrative
PLT ATTEMPTED INSTRUMENT APPROACH IN CONDITIONS CONDUCIVE TO STRUCTURAL ICING; I.E., FOG, LIGHT SNOW, TEMP 32F. ACFT NOT EQUIPPED FOR DEICE. STRUCTURAL ICE ACCRETION DURING APPROACH AND CLIMB-OUT FOLLOWING MISSED APPROACH DEGRADED ACFT PERFORMANCE SO THAT CLIMB TO ASSIGNED ALT/VFR CONDITIONS NOT POSSIBLE. ACFT CONTINUED TO ACCUMULATE ICE IN IMC, EVENTUALLY FORCING DESCENT TO GROUND CONTACT.

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
