NTSB narrative

DURING FLIGHT AT FL370, THE AIRPLANE ENTERED A CLOUD LAYER AND ENCOUNTERED TURBULENCE. A DESCENT WAS MADE TO FL330. AS POWER WAS BEING APPLIED FOR LEVEL OFF AT FL330, THE N1 INDICATION DID NOT RESPOND. AT FL310 THE #1 ENGINE FLAMED OUT. WEATHER INCLUDED ICE CRYSTALS, THUNDERSTORM OUTFLOW, AND TURBULENCE. DURING AN ATTEMPTED CROSS BLEED AIR START, THE #2 ENGINE FLAMED OUT. WITH THE AIR DRIVEN GENERATOR (ADG) DEPLOYED, THE CREW WAS SUCCESSFUL WITH AN APU ASSISTED START. BOTH ENGINES WERE STABILIZED BY 5000 FEET, AND THE FLIGHT LANDED SAFELY. INTERVIEWS AND INFORMATION FROM THE CVR REVEALED THAT THE CREW DID NOT CALL FOR THE EMERGENCY CHECKLIST AND THAT THEY LACKED KNOWLEDGE OF THE AIRPLANE SYSTEMS. AS THE CREW RECOGNIZED THE INITIAL POWER LOSS, THE CAPTAIN ASKED THE FIRST OFFICER IF HE HAD TURNED ON ENGINE ANTI-ICE. HE REPLIED THAT HE HAD NOT. THE CREW HAD NOT ATTENDED A FORMAL TRAINING COURSE FOR THE CL 600. THE CAPTAIN AND COPILOT RECEIVED TYPE RATINGS FROM A DESIGNATED PILOT EXAMINER (DPE) IN MAY AND MARCH 1994, RESPECTIVELY. TESTS OF THE FUEL CONTROL UNITS REVEALED DISCREPANCIES IN THE START AND ACCELERATION SCHEDULES; HOWEVER, NO DISCREPANCIES WERE FOUND THAT WOULD HAVE CONTRIBUTED TO THE FLAMEOUTS.

Probable cause

THE FLIGHT CREW'S IMPROPER USE OF THE ANTI-ICE SYSTEM, WHICH RESULTED IN ENGINE ICE, SUBSEQUENT ICE INGESTION, AND ENGINE FLAMEOUT. FACTORS RELATED TO THE ACCIDENT WERE: FAILURE OF THE FLIGHT CREW TO FOLLOW THE CHECKLIST PROCEDURES AFTER FLIGHT INTO ADVERSE WEATHER CONDITIONS, AND THE AIRCREW'S LACK OF FAMILIARITY WITH THE AIRCRAFT REGARDING FLIGHT IN ICING C0NDITIONS.

  • 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 1994-10-17.
