## Discrepancy

AFTER TAKEOFF FROM CLE ON FLIGHT 4166 THE NLG WOULD NOT RETRACT ALONG WITH A GEAR DISAGREE WARNING.  CREW CYCLED THE GEAR, NO HELP.  THE AIRCRAFT THEN DIVERTED TO DTW AND SWAPPED TO ANOTHER AIRCRAFT.  REMOVED AND REPLACED NLG SELECTOR VALVE IAW CRJ200AMM 33-22-20.  OPS CHECK GOOD AT THIS TIME.  C/W PA 05-018 SER NR 1.
