## Discrepancy

DURING CRUISE, TWO HRS OUT, THE CREW REPORTED THAT THEY HAD AN ELECTRICAL SMELL IN THE COCKPIT.  THEY FOLLOWED THE COM AND ISOLATED THE SMELL TO THE L1 WINDOW.  THEY SHUT THE WINDOW HEAT OFF OF THE L1 WINDOW AND CONTINUED ON TO DESTINATION.  LANDING WAS UNEVENTFUL. MX REPAIRED A SHORTED WIRE TO THE WINDOW AND IS INSTALLING A NEW WINDOW.  WORK IS STILL IN PROGRESS.  (K)
