## Discrepancy

(CAN) PILOTS EXPERIENCED STRONG VIBRATIONS ON ENGINE NR 1 FOLLOWED BY AN INCREASE IN INTER TURBINE TEMPERATURE (ITT).  THEY ATTEMPTED TO REDUCE THE ITT TO NORMAL OPERATING LIMITS BY REDUCING POWER.  HOWEVER, AFTER 2 MINUTES, ITT STARTED INCREASING WITHOUT ANY PLA MOVEMENT OR CONTROLS.  PILOTS THEN ELECTED TO SHUTDOWN ENGINE NR 1 AND LANDED UNEVENTFULLY WITH A SINGLE ENGINE LANDING.  THE ON GROUND TROUBLESHOOTING REVEALED THE COMPRESSOR ROTOR DOES NOT ROTATE. THE ENGINE WILL BE REMOVED FOR INVESTIGATION AND REPAIR.
