NTSB narrative
WHILE EN ROUTE ON A DARK NIGHT, THE AIRCRAFT COLLIDED WITH MOUNTAINOUS TERRAIN IN A HEAVILY WOODED, SNOW COVERED AREA. AN INVESTIGATION REVEALED THAT THE PLANE CRASHED WHILE IN OR NEAR LEVEL FLIGHT AT AN ALTITUDE OF ABOUT 4500 FT MSL. THE TOP OF THE MOUNTAIN WAS ABOUT 5200 FT. THERE WERE BROKEN AND OVERCAST SKY CONDITIONS WELL ABOVE THE ALTITUDE OF THE CRASH SITE. THERE WAS NO MOON ON THAT NIGHT AND THE CLOUDS WOULD HAVE BLOCKED OUT ALL REFERENCE TO THE SKY. ALSO, THERE WERE NO KNOWN GROUND REFERENCE LIGHTS IN THE AREA OF THE ACCIDENT.

- 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 1982-05-15.
