## Discrepancy

DURING SCHEDULED MAINTENANCE A CRACK WAS VISUALLY IDENTIFIED ON THE RIGHT UPPER OUTBOARD RIB CAP COMMON TO THE CLOSEOUT RIB LOCATED AT RWS 106.79 (OEM: 5122115-12). THIS CRACK WAS IDENTIFIED IN THE RADIUS OF THE CAP TRAVELING FORWARD AND AFT, AND MEASURES APPROXIMATELY 1.845 INCHES LONG. THIS CAP ALONG WITH THE INBOARD CAP (OEM: 5122115-14) AND THE RIB (OEM 5122115-56) HAVE BEEN REPLACED AS A MATCHED SET USING SERVICEABLE PARTS.
