## Discrepancy

PDX - AFTER SELECTING THE GEAR "UP", THE MAIN GEAR REMAINED IN TRANSIT FOR A EXTENDED PERIOD OF TIME.  WHEN PLACED TO "DOWN" NO ACTIVITY FOR 5 SECONDS OR SO.  RETURNED TO THE FIELD AND ACCOMPLISHED A UNEVENTFUL LANDING.  MAINTENANCE REPLACED THE BALANCE RELIEF VALVE.  OPERATIONAL CHECKS GOOD.  AIRCRAFT RETURNED TO SERVICE.
