NTSB narrative
THE PLT STATED THAT THE ACFT DRIFTED LEFT AFTER TOUCHDOWN. PROPS WERE BROUGHT TO THE BETA RANGE, & CORRECTION WAS ADDED WITH RIGHT SPOILER & RIGHT RUDDER. THERE WAS AN IMMEDIATE DROPPING OR TURNING TO THE LEFT & THE ACFT HIT A SNOWRIDGE. BOTH ENGS WERE FEATHERED & THE ACFT SLID ALONG THE SNOWRIDGE. THE LEFT WING TIP WAS STRIKING THE GROUND ALONG WITH THE LEFT SIDE OF THE FUSELAGE. THE LEFT MAIN LANDING GEAR DRAG STRUT WAS SHEARED FLUSH WITH THE BARREL CAUSING THE GEAR TO COLLAPSE. METALLURGICAL TESTS REVEALED THAT THE ROD HAD BEEN OVERLOADED & HAD NOT BEEN WEAKENED BY CORROSION, CRACKS OR FATIGUE PRIOR TO 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 1983-03-19.
