## Discrepancy

YVR - FLIGHT 2124 - THE CREW PERFORMED A MISSED APPROACH WHEN AFTER SELECTING THE GEAR DOWN, THE GEAR FAILED TO RETRACT.  THE GEAR WAS LOWERED WITH THE ALTERNATE EXTENSION.  THE LANDING WAS UNEVENTFUL.  MAINTENANCE INSPECTED THE AIRCRAFT AND REPLACED THE LANDING GEAR SELECTOR VALVE.  OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
