## Discrepancy

PIT - FL 441 - AFTER TAKEOFF FROM PIT AND REACHING 6000 FEET, CREW COULD NOT PRESSURIZE THE AIRCRAFT.  FLIGHT RETURNED TO PIT AND LANDED WITH NO FURTHER INCIDENT.  MAINTENANCE FOUND A CRIMPED SENSE LINE TO THE PRESSURE CONTROLLER.  LINE WAS REPLACED AND REPOSITIONED SO AS NOT TO CAUSE A CRIMPING CONDITION.  (M)
