NTSB narrative

THE PILOT RECEIVED TWO WX BRIEFINGS; BOTH INDICATING ICING CONDITIONS EN ROUTE TO HAYS. IN ADDITION, BOTH BRIEFINGS ADVISED OF A SIGMET FOR REPORTED MODERATE-TO-SEVERE ICING IN FREEZING RAIN BELOW 4500 FT MSL. HE TELEPHONED BOTH DISPATCH AND THE CHIEF PILOT; THE CONSENSUS WAS THAT THE WX HAD NOT DEVELOPED AS FORECAST AND THE ADVERSE WX APPEARED TO BE EAST OF HAYS (1ST LANDING LOCATION). WHILE DESCENDING INTO HAYS, THE AIRPLANE ACCUMULATED ICE RAPIDLY. THE PILOT DID NOT SEE THE FIELD AT MDA AND EXECUTED A MISSED APPROACH. HE WAS SUBSEQUENTLY UNABLE TO CLIMB OUT OF ICING CONDITIONS, AND THE AIRPLANE SETTLED TO THE GROUND WITH FULL POWER. THE AIRPLANE WAS NOT EQUIPPED FOR FLIGHT INTO KNOWN ICING CONDITIONS. IT DID INCORPORATE STC SA2573CE WHICH INSTALLS SYNTHETIC RUDDER STRIPS ON THE WING/TAIL LEADING EDGES. THE ANTI-ICING 'SHOES' ARE SPRAYED WITH GLYCOL TO HELP PREVENT ICE BUILD-UP IF ICING CONDITIONS ARE ENCOUNTERED IN FLIGHT. THE PILOT STATED THAT THE OWNER REPRESENTED THE STC AS MEETING FAR 135.227 FOR FLIGHT INTO ICING CONDITIONS.

Probable cause

THE PILOT'S CONTINUED FLIGHT INTO ADVERSE WEATHER AND THE OWNER'S REPRESENTATION THAT THE AIRPLANE MET THE REQUIREMENTS FOR FLIGHT INTO ICING CONDITIONS. THE WEATHER AND AIRFRAME ICE WERE FACTORS IN 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 1993-01-12.
