NTSB narrative

PLT AND FOUR PAXS WERE RETURNING HOME FROM A SKI VACATION. A WITNESS AT THE ARPT OBSERVED A NORMAL TAKEOFF AND SAW THE ACFT TURN TOWARDS AN AREA OF HIGH TERRAIN LOCATED APPROXIMATELY 1.5 MILES FROM THE STEAMBOAT ARPT. THE WITNESS OBSERVED N36TS CONTINUE ON A HEADING TOWARDS COPPER RIDGE AT AN ALTITUDE THAT WAS NOT SUFFICIENT TO CLEAR THE SUMMIT. THE ACFT COLLIDED WITH TREES AND THE GROUND APPROXIMATELY 100 FEET BELOW THE SUMMIT. THE ACFT WAS DESTROYED BY A POST CRASH FIRE. PERFORMANCE CHARTS FOR THE ACFT INDICATED A RATE OF CLIMB OF 1,060 FPM AND A DISTANCE OF APPROXIMATELY 5 MILES TO CLIMB FROM 6,879 FEET TO 8,400 FEET. THERE WAS NO EVIDENCE OF A MECHANICAL MALFUNCTION OR FAILURE OF THE ACFT STRUCTURE, FLT CONTROL SYS, ENG OR PROP PRIOR TO THE INITIAL IMPACT. ATTEMPTS TO LOCATE THE PLTS LOG BOOKS FOR FLT TIME WAS UNSUCCESSFUL. TIME EST FROM MED RECORDS.

Source notes (5)
  • 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.
  • API snapshot SHA-256: 06dfcc5517a8b2df59f4efb5d483a46bd28e46276d07eb7f4d1271141d2f6eda; retrieved 2026-09-21T04:18:55.236Z.
  • Corrected after a review of the NTSB narrative, which states these values explicitly: departure. The narrative states "A WITNESS AT THE ARPT OBSERVED A NORMAL TAKEOFF" toward high terrain "APPROXIMATELY 1.5 MILES FROM THE STEAMBOAT ARPT"; the departure was not recorded.
