UPON INSPECTION, ADDITIONAL CRACKS WERE FOUND EXTENDING FROM FS 430 TO 447 AT LBL 55.  IN ADDITION, UPON REPAIR DOUBLER REMOVAL, NUMEROUS REPAIR FASTENER HOLES WERE FOUND WITH SHORT EDGE DISTANCE.  THE DAMAGE WAS REMOVED RESULTING IN A CUTOUT FROM LBL 54 TO 58 AND FROM STA 430 TO 447.  THIS DAMAGE WAS REPAIRED WITH DOUBLERS.
