## Discrepancy

DURING DAILY PREFLIGHT INSPECTION RUBBING SOUNDS HEARD UNDER CABIN FLOOR WHEN MOVING CONTROL YOLK LEFT AND RIGHT (ROLL AXIX).  INVESTIGATION OF SOUND REVEALED THAT TWO SCREWS (P/N S1021Z8-10) HOLDING STAINLESS STEEL SCUFFBOARD PLATE (P/N 04130264-4) TO CABIN FLOOR PROTRUDED THROUGH CABIN FLOOR, INTERFERED WITH AND RUBBED ON AILERON CONTROL CABLES (P/N 0400107-41).  CABLES EXHIBITED RUB MARKS.  POTENTIAL EXISTS THAT SCREWS COULD SEVER CONTROL CABLES LEADING TO LOSS OF AILERON CONTROL.
