NTSB narrative

THE ACFT HAD DESCENDED THROUGH A CLOUD LAYER ENROUTE FOR THE SCHEDULED LNDG AT IAD AND ACCORDING TO THE CREW HAD PICKED UP SOME TRACE RIME ICE ON ITS WING SURFACES. ALTHOUGH PITOT AND SAS (STALL AVOIDANCE SYSTEM) HEAT WERE USED THE CAPTAIN ELECTED NOT TO USE ENGINE INLET ANTI-ICE. JUST INSIDE THE OUTER MARKER THE LEFT ENGINE LOST POWER FOLLOWED SHORTLY BY THE RIGHT ENGINE. THE CAPTAIN WAS ABLE TO SET THE ACFT DOWN IN AN OPEN FIELD WHERE THE GEAR COLLAPSED DURING THE LANDING ROLL. THE ENGINES WERE SUCCESSFULLY RUN-UP AT THE GARRETT FACILITY. THE FLT MANUAL CONTAINS A WARNING AND A NOTE STATING THAT ENGINE HEAT AND CONTINUOUS IGNITION MUST BE USED AFTER LEAVING ICING CONDITIONS UNTIL THE PLT IS CONFIDENT THAT ANY SIGNIFICANT RESIDUAL ICE WILL NOT BE INJESTED INTO THE ENGINES. ICE WAS FOUND LYING BENEATH THE RT WING WHICH MATCHED THE CURVATURE OF THE LEADING EDGE OF THE WING. A ROUND CONICAL SHAPED PIECE OF ICE WAS FOUND ALONG THE WRECKAGE PATH WHICH MATCHED THE NOSE OF THE PROPELLER SPINNER.

  • 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 1987-12-18.
  • API snapshot SHA-256: 64e0fc58852f744113cdccbf344e8ac6857562a04b4f0b7cd65316b9d386c007; retrieved 2026-09-18T19:33:33.141Z.
