## Discrepancy

FLIGHT WAS DIVERTED. THE LANDING GEAR ALTERNATE EXTENSION WAS USED.  ONCE LANDED, THE CAPTAIN FOUND HYD FLUID DRIPPING FROM NR 2 LOWER ENGINE COWL DRAINS AND PULLED THE CVR AND FDR CIRCUIT BREAKERS.  AFTER THOROUGH INSPECTION BY MAINTENANCE PERSONNEL IT WAS DISCOVERED THAT THE EDP, ENGINE DRIVEN PUMP, SUFFERED CATASTROPHIC FAILURE ALLOWING THE NR 2 HYD SYSTEM TO LOSE ALL HYD FLUID. THE NR 2 EDP WAS REPLACED IN ADDITION TO ALL RELATED FILTERS AND A SIMPLIFIED FLUSH PROCEDURE WAS ACCOMPLISHED.
