REPAIR OF EXISTING REPAIR AT BS 2320, STR 22R.  THE EXISTING REPAIR WAS REMOVED FROM THE AIRCRAFT AND DISCARDED, AND THE EXISTING DENT WAS TRIMMED AWAY PER B747 GUIDELINES.  THE FUSELAGE SKIN TRIM OUT AND EXISTING FASTENER HOLES COMMON TO THE REPAIR AREA WERE HFEC INSPECTED TO ENSURE A CRACK FREE CONDITION AND THE DOUBLER AND TRIPLER WERE INSTALLED TO RESTORE THE ORIGINAL SKIN PANEL.
