## Discrepancy

DURING CLIMB BOTH PILOTS SMELLED ELECTRICAL SMOKE, THEY IMMEDIATELY DONNED OXYGEN MASKS. THERE WAS NO SMOKE IN THE COCKPIT. FLIGHT ATTENDANTS REPORTED SOME WHITE SMOKE IN THE CABIN. THE EVENT LASTED ABOUT TWO MINUTES. THE FLIGHT CONTINUED AND LANDED WITHOUT INCIDENT. MAINTENANCE FOUND THE COOLING TURBINE SEIZED AND TURBINE BLADES DAMAGED. REMOVED AND REPLACED THE COOLING TURBINE, OPERATIONALLY CHECKED AND RETURNED TO SERVICE.
