## Discrepancy

CREW REPORTED DURING INTERMEDIATE CLIMB, IT TOOK FULL RIGHT AILERON TRIM TO KEEP THE AIRCRAFT WINGS LEVEL.  CREW NOTED NO CONTROLLABILITY PROBLEMS.  CRUISE TRIM SETTING APPEARED MORE NORMAL AT 3 RIGHT.  AIRCRAFT REQUIRED NO AILERON RETRIMMING DURING DESCENT.  MAINTENANCE FOUND THE FORWARD AILERON/RUDDER INTERCONNECT SPRING BROKEN.  THE BREAK OCCURRED BETWEEN THE HOOK OF THE SPRING AND THE COILS OF THE SPRING.  REPLACED FORWARD SPRING IN ACCORDANCE WITH THE BEECH CRAFT MAINTENANCE MANUAL.  A TEST FLIGHT WAS PERFORMED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
