## Discrepancy

THE CREW REPORTED THAT THEY RECEIVED BLEED 1 AND BLEED 2 OVERPRESSURE MESSAGES AFTER TAKEOFF. THE CREW DECLARED AN EMERGENCY AND RETURNED TO THE FIELD.  AFTER LANDING, A BLEED 1 FAIL MESSAGE WAS ALSO REPORTED. MAINTENANCE REPLACED THE ENGINE 1 NAPRSOV.  OPS CHECKS WERE GOOD WITH NO FURTHER DEFECTS NOTED.
