## Discrepancy

INVESTIGATION SHOWS THAT  INTERMITTENT T/O CONFIGURATION WARNING HAD OCCURRED SEVERAL TIMES. DESPITE SEVERAL TESTS.  NO INDICATION OF FAULTS HAVE BEEN FOUND.  IT WAS COMPLAINED ABOUT SLOPPY FUNCTION OF RUDDER TRIM SWITCH, TOO FAST AND STARTED IN OPPOSITE DIRECTION. CONSEQUENTLY SWITCH WAS REPLACED.  A/C RETURNED TO SERVICE.  NO FURTHER COMPLAINT OF T/O CONFIGURATION OR RUDDER TRIM HAS BEEN ENTERED.
