## Discrepancy

INSPECTION OF THE C1 DOOR OPENING FWD FRAME AT FS 560 PER   AD 99-23-13 REVEALED 3 CRACKS IN THE WEB (1 BELOW THE NR 4 STOP AND 2 BELOW THE NR 1 STOP).  THE WEB WAS CUT AT THE NR 6 STOP AND THE UPPER SECTION WITH THE CRACKS REMOVED.  WEB REMOVAL REVEALED SEVERAL CORRODED FASTENER HOLES IN THE INNER CHORD WHICH WAS THEN CUT TO REMOVE THE DAMAGED SECTION. NEW SECTIONS OF WEB AND CHORD WERE SPLICED PER SRM 51-40.
