## Discrepancy

DURING ACCOMPLISHMENT OF 109EP-112, ENGINE MOUNT INSTALLATION INSPECTION AND RT AND LT V-SHAPED SUPPORTS AND REAR SUPPORT LEGS REPLACEMENT.  NR 2 ENGINE INBD MOUNT V-SHAPED SUPPORT, FORWARD LEG HAD LATERAL PLAY.  UPON REMOVAL OF MOUNT, MOUNT BOLT WAS FOUND WORN THRU ABOUT 90 PERCENT OF BOLT THICKNESS. V-SHAPED SUPPORT MOUNT HOLD WAS FOUND ELONGATED.  SHEARING OF THE BOLT WOULD HAVE CAUSED LATERAL SHIFTING OF ENGINE AND SHEARING OF ENGINE TO MAIN TRANSMISSION DRIVESHAFT. ENGINE OR MOUNT HAS NOT HAD A HISTORY OF REMOVAL OR REPLACEMENT FROM THE ACFT SINCE FACTORY.  SUGGEST SHORTENING COMPLIANCE TIME OF TB 109EP-112 OR FLEET WIDE SPECIFIC INSPECTION.
