## Discrepancy

DURING ROUTINE 1000 HOUR REAPPLICATION OF THE DRY FILM LUBRICANT ON THE FAN BLADE ROOT AREA IT WAS NOTICED THAT GAULLING ON THE BLADE ROOT WAS BEYOND THE .004 MANUFACTURE LIMIT.  A FLY ON DISPOSITION WAS NOT GRANTED BY ROLLS ROYCE AND ALL 24 BLADES ON THE BOTH ENGINES WERE REPLACED WITH NEW PN FW33925.
