## Discrepancy

BWI - AIR TURNBACK - 2/10/01 - ON TAKEOFF THE NR 1 ENGINE HIGH STAGE LIGHT ILLUMINATED.  DURING CLIMB THE AIRCRAFT WAS UNABLE TO MAINTAIN CABIN PRESSURIZATION IN AUTO AND THE CREW SWITCHED TO MANUAL AND CONTROL OF PRESSURIZATION WAS ESTABLISHED AT 10000 FT CABIN ALTITUDE.  THE AIRCRAFT RETURNED TO BWI MAKING AN UNEVENTFUL OVERWEIGHT LANDING.  MAINTENANCE REPLACED THE HIGH STAGE VALVE AND FOUND A FOREWARD CARGO COMPARTMENT NET STRAP CAUGHT IN THE DOOR.  AN ENGINE RUN AND PRESSURIZATION TEST WAS PERFORMED; ALL CHECKS WERE GOOD.  AN OVERWEIGHT LANDING INSPECTION WAS PERFORMED AND NO DISCREPANCIES NOTED.
