## Discrepancy

DURING THE QC FINAL INSP PHASE OF A 100 HR INSP THE INSPECTOR NOTED A CRACK EXTENDING LONGITUDINALLY FWD AND AFT FROM THE LT FWD NAV/VOR ANTENNA MOUNT.  PHOTO`S AND INFOR SENT TO MFG FOR DETERMINATION.  MFG SUGGEST REMOVAL AND REPAIR BY MFG.  BELIEVE PART TO BE WEAK IN THISE MOUNTING AREAS AND SUGGEST A REDESIGN OF THIS AREA TO PROVIDE ADDITIONAL SUPPORT.
