## Discrepancy

DURING FLIGHT, THE SMELL OF ELECTRICAL SMOKE WAS NOTICED BY THE FLIGHT CREW. PULLED CIRCUIT BREAKERS FOR THE LOWER LEFT HEAT CONTROLLER ON WINDOW L1. AIRCRAFT CONTINUED TO DESTINATION AND LANDED WITHOUT INCIDENT.   REPLACED WINDOW L1 AND WINDOW HEAT CONTROL MODULE. OPERATIONAL CHECK GOOD.
