What was found
PILOT REPORTED LOSS OF RUDDER CONTROL IN-FLIGHT ALTHOUGH HE WAS ABLE TO MAINTAIN CONTROL OF THE AIRCRAFT AND MADE AN UNEVENTFUL LANDING. FOUND THE AFT (RIGHT HAND) RUDDER PEDAL TORQUE TUBE WAS BROKEN APPROXIMATELY 7/8 OF THE WAY AROUND THE TUBE JUST TO THE LEFT SIDE OF THE SECTOR GEAR. THIS ALLOWED THE TWO SECTOR GEARS TO DISENGAGE WHICH UNSYNCHRONIZED THE TWO TORQUE TUBES. BECAUSE OF THIS, THE RUDDER CABLE TENSION WAS UNABLE TO BE MAINTAINED.
