## Discrepancy

AFTER TAKEOFF, THE LANDING GEAR DID NOT RETRACT.  THE PILOT DECIDED TO RETURN TO DEPARTURE.  MAINT DETERMINED THAT A UPLOCK WAS OUT OF SEQUENCE.  UPLOCK WAS RECYCLED AND ACFT WAS RETURNED TO SERVICE.  ACFT BLOCKED OUT FOR A SECOND TIME.  AFTER TAKEOFF, LANDING GEAR DID NOT RETRACT FOR THE SECOND TIME. PILOT RETURNED THE ACFT TO DEPARTURE.  ACFT WAS THEN TAKEN FOR A GEAR RETRACTION AND TROUBLESHOOTING.  MX FOUND A BAD LANDING GEAR SELECTOR. THE SELECTOR WAS REMOVED AND REPLACED AND THE ACFT RETURNED TO SERVICE.
