## Discrepancy

THE LOWER FITTING ON THE I/B RIB OF THE RT NR 1 FLAP AT ITS 27.4 WAS FOUND COMPLETELY SEVERED APPROX 6 AFT OF THE FORWARD EDGE.  ALSO, THE EXTERNAL WEB WAS FOUND WITH AN APPROX 4 LONG CRACK ON THE SAME RIB.  THESE CRACKS ARE TYPICAL PER THE LAC S/B 093-57-109 AND WILL BE REPAIRED IN ACCORDANCE WITH THAT S/B.
