## Discrepancy

REPAIR- RIGHT INBD ELEVATOR LEADING EDGE, UPPER SURFACE ELEV STA 77-86.  AN EXISTING REPAIR WAS FOUND OUTBOARD OF THE CRACK LOCATION.  THE EXISTING REPAIR WAS REMOVED TO INCORPORATE THE NEW CRACK INTO THE REPAIR.  UPON DISASSEMBLY IT WAS FOUND THAT THE PRIOR REPAIR AREA WAS A RESULT OF DEFORMATION AND CRACK DAMAGE (CRACK WAS STOPPED DRILLED).  REPAIR OF THIS AREA AND THE NEW CRACK IS ACCOMPLISHED BY TRIMMING OUT THE DAMAGED AREA AND INSTALLING A NEW INTERNAL DOUBLER.  THIS DOUBLER REPLACES THE OLD REPAIR DOUBLER AND THE ORIGINAL PRODUCTION DOUBLER (65B05771-17) PER ECRA 3203-55-035-2.
