## Discrepancy

EMPENNAGE TRIM CONTROL TORQUE FOUND TO HAVE A DEEP GROOVE FROM WEARING ON CAT TRACK/GROMMET WHERE IT PASSES THROUGH STIFFENERS.  THIS TUBE WAS ALSO WELD REPAIRED AT SOME TIME PREVIOUS THEN SWAPPED END FOR END SO TUBE WOULD WEAR ON A NEW SURFACE.  IT APPEARS THIS WAS DONE DURING AN AIRCRAFT REPAIR AFTER AN ACCIDENT.  NO DOCUMENTATION IN AIRCRAFT RECORDS OF THIS REPAIR.  NEW TUBE INSTALLED BY REPAIR STATION.  THIS AIRCRAFT HAD BEEN THROUGH NUMEROUS ANNUAL INSPECTIONS AND NOT REPLACED OR DOCUMENTED.
