## Discrepancy

(CAN) DURING ENGINE RUN, A VIBRATION WAS NOTED ON THE LT ENGINE.  UPON INVESTIGATION MAINTENANCE CREW NOTED THAT THE TAIL PIPE SUPPORT WAS SHEARED.  THE SUPPORT WAS REPLACED.  THE ENGINE WAS GROUND RUN AND THE VIBRATION WAS STILL PRESENT.  THE ENGINE WILL BE REMOVED AND REPLACED WITH A SERVICEABLE UNIT.  IT IS BELEIVED THAT THE ENGINE VIBRATION WAS THE CAUSE OF THE SHEARED TAIL PIPE SUPPORT.
