## Discrepancy

DURING AN INSPECTION, MAINTENANCE FOUND LT WING CENTER SECTION MID-RIB AT WS 83.00 TO HAVE A CRACK 1.1250 INCH LONG.  THE CRACK WAS ALONG THE TOP BEND RADIUS AT THE RIB CENTER STIFFENER ATTACH POINT.  THE FORWARD REINFORCEMENT PN 114-120033-15 WAS ALSO CRACKED AT EACH END.  MAINTENANCE PERFORMED A MAJOR REPAIR BY STOP-DRILLING THE CRACKS, ADDING A DOUBLER, AND REPLACING THE FORWARD REINFORCEMENT.
