## Discrepancy

DURING A PRE-FLIGHT INSPECTION, THE PILOT NOTED WHEN THE LT RUDDER PEDAL WAS PUSHED, NO CONTROL SURFACE MOVEMENT WAS NOTED.  INVESTIGATION REVEALED CONTROL CABLE HAD PULLED ITS ATTACH EAR OFF OF THE TORQUE TUBE.  THE INTERIOR GUST LOCK WAS INSTALLED FREEZING THE RUDDER PEDALS.  NO EXTERNAL GUST LOCK WAS INSTALLED WHICH ALLOWED ALL THE WIND FORCE TO BE TRANSMITTED TO THE TORQUE TUBE.  SUBMITTER SUGGESTS TO USE EXTERNAL GUST LOCKS.
