## Discrepancy

CAPTAIN REPORTED THAT DURING CLIMB THE RT UVC AND GENERATOR WERE DISCONNECTED BY HIGH TEMPERATURE; SO THE FLIGHT CREW PERFORMED THE DRIVE GENERATOR MALFUNCTION PROCEDURE, CONFIRMING THE FAILURE AND SHUT DOWN THE UVC AND GENERATOR, CONTINUING TO DESTINATION. DURING MX REVISION, IT WAS DETECTED METAL CHIPS IN THE IN THE UVC; SO THE RT UVC WAS REPLACED AND AIR /OIL HEAT EXCHANGE IAW MM 24-10-1 AND 24-10-3, TESTED CORRECT.
