## Discrepancy

DURING TAXI, THE FLIGHT CREW NOTICED A FULL LEFT BIAS DEFLECTION IN THE AILERON SYSTEM.  MAINTENANCE FOUND ONE OF THE AILERON INTERCONNECT SPRINGS HAD FRACTURED AT THE END RING THAT PROVIDES CONNECTION TO THE BRIDLE.  IT IS FELT THAT THE ISSUE MAY HAVE BEEN INDUCED DURING PHASE INSPECTION REQUIREMENTS TO REMOVE THE SPRINGS DURING TENSIONING PROCEDURES AND THAT TOOL MARKS FROM PLIERS OR OTHER MECHANICAL MEANS MAY HAVE SCORED THE SPRING PROVIDING AREAS FOR STRESS RISERS TO DEVELOP.  A COMPANY SUPPLEMENTAL INSPECTION HAS BEEN INSERTED INTO OUR PROCESS CONTROL FOR THIS ISSUE.
