## Discrepancy

(CAN) A FEW MINUTES AFTER DEPARTURE, THE FLIGHT CREW NOTICED A BURNING ODOR FOLLOWED BY SMOKE EMITTING FROM THE GLARESHIELD. ON INVESTIGATION BY MAINTENANCE, THE FLEX DRIVE BETWEEN THE WIPER MOTOR AND PILOT CONVERTER WAS FOUND TO BE OVERHEATING AND MELTED A PORTION OF THE WINDSHIELD DEFROST DUCTING. WHEN THE FLEX DRIVE WAS REMOVED, IT WAS SEIZED. THE FLEX DRIVE WAS REPLACED, THE WINDSHIELD DEFROST DUCTING REPAIRED AND THE AIRCRAFT RETURNED TO SERVICE.
