## Discrepancy

ON DESCENT FOR LANDING AT KPHX THE PILOT REPORTED THAT THE LEFT ATTITUDE INDICATOR BECAME ERRATIC AND STARTED SMOKING.  THE PILOT PULLED THE CIRCUIT BREAKER, THE SMOKE STOPPED AND THE PILOT LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE WIRING AND CIRCUIT BREAKER NO DEFECTS WERE NOTED.  AS A PRECAUTIONARY MEASURE THE CIRCUIT BREAKER WAS REPLACED. THE ATTITUDE INDICATOR HAS BEEN REMOVED FROM THE AIRCRAFT AND SHIPPED BACK TO THE OVERHAUL FACILITY FOR A TEAR DOWN REPORT.  TEAR DOWN RESULTS WILL FOLLOW.
