NTSB narrative
WHILE ON AN IFR FLT AT 6000 FT, THE PLT REQUESTED, AND WAS GRANTED A DEVIATION AROUND WX. LATER, N335W INFORMED DENVER ARTCC THAT THEY WERE GOING TO GET INTO SOME MODERATE TURBULENCE FOR A LITTLE BIT BUT THAT IT LOOKED LIKE THE LIGHT AT THE END OF THE TUNNEL. THE ACFT DISAPPEARED FROM THE DENVER ARTCC RADAR. THE WRECKAGE WAS LOCATED SPREAD OVER AN AREA APPROXIMATELY 1 MI BY 1/4 MI. THE INVESTIGATION DID NOT REVEAL ANY MALFUNCTION OF THE ENG OR ACFT COMPONENT AND THE PATHOLOGICAL/TOXICOLOGICAL EXAMINATION OF THE PLT ALSO WERE NEGATIVE.

- 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.
