## Discrepancy

PDX - AFTER TAKEOFF AUTO PRESSURE CONTROLLER WENT TO MANUAL MODE AND IT WOULD NOT CONTROL THE CABIN PRESSURE.  DURING DESCENT IT BEGAN TO WORK.  RETURNED TO THE FIELD AND ACCOMPLISHED A UNEVENTFUL LANDING.  MAINTENANCE REPLACED THE NR 2 SAFETY OUTFLOW VALVE.  OPERATIONAL CHECKS GOOD AIRCRAFT RETURNED TO SERVICE.
