## Discrepancy

DURING A MBV INSPECTION DISCOVERED THE RT WING RIB NR 5 TO BE CRACKED.  THE CRACKS EXTEND OUT FROM THE LIGHTENING HOLES.  THE CRACKS CAN BE VISIBLE SEEN BY LOOKING THROUGH ACCESS PANELS 632AB.  LOOK THROUGH THE ACCESS PANEL HOLE AND LOOK I/B THROUGH THE LIGHTENING HOLES OF RIB 6. WE HAVE SEEN CRACKS ON A PREVIOUS AIRCRAFT WITH THE CRACKS FROM THE LIGHTENING HOLES ALONG WITH A CRACK EXTENDING UP FROM THE BOTTOM FLANGE.
