## Discrepancy

WHILE COMPLETING THE RECURRING NDT INSPECTION OF THE FAN DISC, A CRACK WAS FOUND.  THERE WERE NO VISUAL INDICATIONS OF A CRACK.  (ATTACHED SHEET FOR LOCATION OF CRACK ON FAN DISC.) THE FAN DISC HAD BEEN NDT 117 CYCLES PREVIOUS TO THIS NDT THAT REVEALED A CRACK.  A NEW FAN MODULE HAS BEEN INSTALLED AND THE AIRCRAFT HAS BEEN RETURNED TO SERVICE.
