## Discrepancy

CREW REPORTED THAT AT FL320 THE CAPTAIN'S DV WINDOW BEGAN SQUEALING AND BECAME SO LOUD THAT COMMUNICATION WAS NEARLY IMPOSSIBLE.  THE FLIGHT CREW DECIDED TO RETURN TO LGA AND LANDED WITHOUT INCIDENT.  MAINTENANCE REPLACED THE CAPTAIN'S DV WINDOW SEAL IAW MM 56-11-02 AND PRESSURE AND LEAK CHECKED THE SYSTEM IAW MM 21-31-00 WITH NO DEFECTS NOTED.
