## Discrepancy

(CAN) STARTER/GENERATOR WAS REMOVED SERVICEABLE, FOR OVERHAUL. DURING OVERHAUL, THE STATOR FAILED HI-POT INSULATION BREAKDOWN INSPECTION, EVEN AFTER EXTENSIVE REPEATED CLEANING.  VARNISH ON WINDOW WAS DARKER THAN NORMAL. THIS UNIT RAN WITH LONG-LIFE BRUSHES P/N 23088-1321.  LUCAS HAD PROBLEMS WITH EXCESSIVE HEAT BUILDING ON THE PILATUS INSTALLATION AND SUBSEQUENTLY ISSUED SERVICE BULLETIN NR  23085-014-24-01 IN JULY 1999 TO REMOVE THIS BRUSH AND INSTALL P/N 30300-1413. THE STATOR HAS NOW BEEN REWOUND,THE SB HAS BEEN ACCOMPLISHED, AND THE STARTER/GENERATOR IS BEING PREPARED FOR RETURN TO SERVICE AS OVERHAULED.  (X)
