## Discrepancy

(CAN) ON COMPLETION OF A REGULAR SLAT TRACK LUBE, A SLIGHT `CLICKING` SOUND WAS NOTED DURING THE FINAL STEP OF A SLAT OPS CHECK. UPON INSPECTION IT WAS NOTED THAT THE SOUND WAS BEING CAUSED BY: 1- RT WING OTBD SEAL ON NR 4 SLAT IS WORN AND CRACKED.  2- RT WING NR 4 SLAT INBD NR 8 SLAT TRACK MOBILE COVER ACTUATING FORKS WERE NOTED BENT. THIS CAUSES THE COVER TO RIDE UNEVENLY DURING SLAT EXTENSION AND RETRACTIONS.  MFG HAS BEEN NOTIFIED OF THE ISSUE.
