NTSB narrative
DURING A CLIMB THROUGH FL200, THE CREW HEARD A NOISE, FOLLOWED BY THE LOSS OF POWER FROM THE RIGHT ENGINE AND A YAW. THEY SECURED THE RIGHT ENGINE AND CONTINUED ON TO THEIR DESTINATION. AN INSPECTION OF THE RIGHT ENGINE REVEALED THAT THE NUMBER 3 TURBINE WHEEL HAD FAILED AND THAT THE FAILURE WAS UNCONTAINED. THE FAILURE ALSO SEVERED THE HYDRAULIC LINES IN THE EQUIPMENT BAY AND SEPARATED THE BAY DOOR. THE PIECES OF THE TURBINE WHEEL WERE NOT RECOVERED. DURING THE LANDING ROLL THE CREW EXITED ON A TAXIWAY BUT DID NOT HAVE SUFFICIENT CONTROL TO STAY ON THE TAXIWAY. THE AIRPLANE CAME TO REST IN THE GRASS.
Probable cause
THE UNCONTAINED FAILURE OF THE TURBINE WHEEL. A FACTOR WAS THE RESULTANT LOSS OF HYDRAULIC POWER.

Source notes (4)
- 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 1994-10-11.
