What was found
ON CLIMBOUT AROUND FL200, WE STARTED SMELLING A STRONG SMELL THAT INCREASED IN INTENSITY. WE IDENTIFIED THE SOURCE AS A POSSIBLE ELECTRICAL SMOKE/FIRE, AND SOON AFTER WE STARTED SEEING SMOKE COMING OUT OF THE RIGHT WINDSHIELD ELEMENT BEHIND THE CAUTION/ADVISORY PANEL. WE THOUGHT IT WAS THE WINDSHIELD HEAT, SO WE TURNED OFF THE SWITCH, AND SOON AFTER THE SMOKE DISSIPATED. WE DONNED THE OXYGEN MASKS AND PERFORMED THE AIRCRAFT SMOKE IN FLIGHT CHECKLIST. NO CAUTION MESSAGES APPEARED IN FLIGHT OR ON THE GROUND. DIVERTED AND LANDING UNEVENTFUL. REMOVED FROM SERVICE. REPLACED RH WINDSHIELD PER Q400 AMM TASKS 56-10-01-000/400-801. REF: W/O 319513, N/R-1 THROUGH N/R-14 FOR TROUBLESHOOTING AND ALL WORK PERFORMED. OPERATIONAL CHECK FLIGHT GOOD. AIRCRAFT RETURNED TO SERVICE.
