## Discrepancy

(CAN) WHILE BIRD TOWING WITH STC SH04-57 INSTALLED, THE GEN WENT OFF LINE.  THERE WERE REPORTS OF A BURNING ODOR IN THE CABIN, FOLLOWED SHORTLY BY THE GEN FAIL WARNING.  THE PILOT MADE AN UNSCHEDULED, UNHURRIED LANDING.  DISCOVERED THE STARTER GEN HAD TWO BURNED, ERODED & DISINTEGRATING BRUSHED & A COMMUTATOR IN POOR SHAPE.  THE STARTER WAS REPLACED, THE ACFT BEHAVED NORMALLY & WAS RETURNED TO SERVICE.  THE STARTER WAS SENT FOR INVESTIGATION & OVERHAUL.
