## Discrepancy

DURING ENGINE REMOVAL FOR 18K LLP SHOP VISIT, MAINTENANCE DISCOVERED WHAT APPEARED TO BE A CRACK IN A FORWARD ENGINE MOUNT YOKE BEARING.  THE MOUNT YOKE WAS REMOVED FROM SERVICE AND SENT OUT FOR REPAIR.  THE REPAIR VENDOR CONFIRMED THE BEARING RACE TO BE CRACKED.  AIRLINE HAS REQUESTED THE BEARING BE RETURNED FOR ANALYSIS.
