## Discrepancy

CREW REPORTED THAT AFTER LEVELING OFF AT 23,000FT, REPORTED SMELLING A BURNING OIL/ELECTRICAL ODOR.  THE CAPTAIN AND FIRST OFFICER DONNED OXYGEN MASKS AND PROCEEDED TO DIVERT TO IND.  THE ODOR WAS CONTAINED MAINLY TO COCKPIT BUT FLIGHT ATTENDANT DID REPORT A SLIGHT ODOR AT THE FRONT OF THE CABIN.  THE AIRCRAFT DIVERTED TO IND AND LANDED WITHOUT INCIDENT.  THE CREW DID NOT DECLARE AN EMERGENCY OR REQUEST FIRE CREWS.  MAINTENANCE ISOLATED THE ODOR TO THE NR 1 ENGINE.  THE NR 1 ENGINE WAS REPLACED WITH NO FURTHER DEFECTS NOTED.
