## Discrepancy

(CAN) DURING A PREFLIGHT WALK AROUND, IT WAS FOUND THAT THE FLAP SYS WAS MAKING A GRINDING NOISE WHEN THE FLAPS WHERE SELECTED UP.  MAINTENANCE DISCOVERED THAT THE FLAP SYS ACTUATOR HAD FAILED DUE TO HIGH CYCLES.  THERE IS NO AIRWORTHINESS LIMITATIONS TO REPLACE THE ACTUATOR FROM THE MFG BUT THE COMPANY HAS CHANGED THEIR TRACKING SYSTEM TO REPLACE THE ACTUATOR ASSEMBLY EVERY 8000 CYCLES.
