## Discrepancy

PILOT REPORTED NR 2 ENGINE LOW FUEL PRESSURE WARNING CAME ON.  WARNING EXTINGUISHED AFTER SELECTING ELECTRIC STANDBY PUMP ON.  MAINTENANCE REPLACED LOW PSI FUEL PUMP DUE INTERNALLY DISCONNECTED DRIVE SHAFT (SECOND OCCURRENCE OF THIS TYPE FAILURE ON THIS ENGINE WITHIN 30 DAYS).  VERIFIED PUMP DRIVE SHAFT WOULD EASILY DE-COUPLE FROM ROTOR WHEN TURNING SHAFT BY HAND.
