## Discrepancy

(CAN) THE TURBOMACHINERY WAS SENT FOR REPAIR AFTER AN INFLIGHT SHUTDOWN.  THERE WAS A REPORT OF A RISE IN T6 DURING THE SHUTDOWN, BUT NO OVERTEMP.  THE CAUSE OF THE INFLIGHT SHUTDOWN WAS THE LOSS OF THE HP TURBINE BLADES AND CONSEQUENTLY THE DRIVE TO THE FUEL PUMP, HMU AND THE GENERATOR.  THE CAUSE OF THE HP TURBINE BLADES FAILURE IS NOT PRESENTLY KNOWN, BUT A PRIMARY FAILURE OF ONE OR MORE OF THE HP TURBINE BLADES IS THE MOST LIKELY CAUSE.
