## Discrepancy

PHL  FLT 732  EN ROUTE CLT TO LGW.  DURING CRUISE FLIGHT, THE CREW REPORTS: "NR 2 EPR FAILED, IN N1 MODE LARGE DIFFERENCE IN THRUST LEVERS."  AN OPERATIONAL DECISION WAS MADE NOT TO TAKE AIRCRAFT INTO ETOPS ENVIRONMENT WITH THIS CONDITION.  THE FLIGHT DIVERTED TO PHL, DECLARED AN EMERGENCY DUE TO THE OVERWEIGHT CONDITION OF THE AIRCRAFT, AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REMOVED AND REPLACED THE P2/T2 PROBE ON THE RIGHT ENGINE.
