## Discrepancy

FLIGHT 5542, IAH TO MOB - DURING CLIMB, THE CREW REPORTED THAT THE E2 VIBRATIONS WERE HIGH AND THERE WAS AN INDICATION FOR LOW OIL PRESSURE.  E2 WAS THEN SHUT-DOWN AND THE FLIGHT RETURNED TO IAH AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE ENGINE AND FOUND A LOOSE B-NUT FROM THE LUBE AND SCAVENGE PUMP.  THE B-NUT WAS RE-SECURED AND THE OIL WAS SERVICED.  E2 WAS THEN RUN AND THE OIL PRESSURE AND VIBES WERE BOTH WITHIN LIMITS.
