## Discrepancy

DURING A VISUAL INSPECTION OF THE NEW AC, ENGINE MOUNT WAS NOTED HAVING AN EXCESSIVE CHAFFING CAUSED BY A TINNERMAN NUT USED FOR WINTER BAFFLE ON IB SIDE OF OIL COOLER.   SEVERAL OTHER AC HAVE BEEN NOTED WITH TINNERMAN NUTS ON THE OIL COOLERS BUT NO DAMAGE NOTED YET.  INSP OF ENGINE MOUNT SHOULD BE DOEN AS SOON AS POSSIBLE AND IF NO DAMAGE TO THE ENGINE MOUNT IS NOTED, THE TINNERMAN NUT SHOULD BE REMOVED AND BOLT AND NUT SHOULD BE INSTALLED WHEN THE WINTER BAFFLE IS NEEDED.
