## Discrepancy

NR 1 ENGINE FAILED TO START.  VALVE INDICATES OPEN.   REPLACED STARTER DUE TO FAILURE. UPON FURTHER TEARDOWN, FOUND THAT THE TURBINE WHEEL BEARING HAD FAILED CAUSING DAMAGE TO THE INLET HOUSING, CAGE, TURBINE WHEEL AND CLUSTER GEARS. THE START VALVE WAS ALSO REPLACED AS A PRECAUTIONARY MEASURE.
