## Discrepancy

(CAN) CAPTAINS ATTITUDE INDICATION HAS FAILED 4 TIMES.  THE VERTICAL GYRO HAS BEEN REPLACED WITH DIFFERENT SN GYROS.  THE ATTITUDE INDICATION WORKS FINE AFTER EVERY GYRO CHANGE.  TALKED TO OVERHAUL FACILITY & WAS TOLD THAT THEY HAD A BAD RUN OF NEW BEARINGS.  WE WILL SEND THE LATEST GYRO BACK TO THE OVERHAUL FACILITY FOR TESTING.  IF TEST IS OK, WE WILL REPLACE THE ATTITUDE INDICATOR.
