## Discrepancy

(CAN) DURING REPLACEMENT OF THE LH RAM FAN, IT WAS DISCOVERED THAT A SECTION OF THE INLET DUCT UPSTREAM OF THE RAM FAN AND HEAT EXCHANGERS WAS ADRIFT, AND THAT THE CLAMPS FOR THAT SECTION OF DUCT WERE NOT SECURED.`, A DISCUSSION WAS HELD WITH THE AME WHO RECTIFIED THE ADRIFT CLAMP THAT WAS FOUND.WHEN WE OPENED THE ACCESS DOOR WE NOTICED THE AFT CLAMP LOOKED A LITTLE LOOSE.  RESOLUTION CLAMP TIGHTENED AS PER AMM 21-52-44-00A-720A (TC# 20190703013)
