## Discrepancy

DURING CLIMBOUT, FIVE MINUTES INTO FLIGHT, THE PILOT OBSERVED THE RT ATTITUDE INDICATOR TUMBLED,  MADE 180 DEGREE TURN BACK TO MAINTENANCE BASE.  ATTITUDE INDICATOR STOPPED ITS TUMBLE AND RIGHTED ITSELF. MX PERFORMED OPS CHECK, FOUND NO DEFECTS NOTED AND COULD NOT DUPLICATE ATTITUDE INDICATOR TUMBLE.  REPLACED ATTITUDE INDICATOR AND PERFORMS OPS/LEAK CHECK NO DEFECTS NOTED.
