## Discrepancy

EXCESSIVE RUDDER TRIM.  VERY SLOW TO EXTEND.  CREW REPORTED FELT MORE LIKE A SPOILER FLOAT, NOT AN ENGINE VIBRATION.  THE NR 2 FLT SPOILER WAS FOUND TO BE LAGGING IN OPERATIONAL TIME IN COMPARISON TO THE REMAINING FLT SPOILERS AND THE NR 10 FLT SPOILER WAS FOUND TO HAVE EXCESSIVE LEAKAGE & THEREFORE REPLACED.  NR 2 SPOILER ACTUATOR ALSO REPLACED.  VERIFICATION TEST FLIGHT CONFIRMS NORMAL OPERATION OF FLIGHT CONTROLS.
