## Discrepancy

DURING THE MX INSP, AFTER THE LAST FLIGHT OF THE DAY, IT WAS DETECTED IN THE LT ENGINE, THE FAN BLADES WITH PLASTIC BAG REMAIN. MX PERFORMED A FOD INSP IAW MM TASK 71-00-00-800-802-F00, DETECTING A GROOVE 1.125 INCHES WIDE ON 360 DEGREES OF ABRADABLE SHROUD. THE FAN BLADES WERE CLEANED AND LUBRICATED IAW MM 72-21-02. ADDITIONALLY, THE NRC A0163724 WAS GENERATED FOR REPAIR THE ABRADABLE SHROUD, LIMITED TO 50 CYCLES TO PERFORM THE REPAIR IAW MM 71-00-00. THE FINAL REPAIR DETAILS WILL BE PROVIDED AS A SUPPLEMENT.
