## Discrepancy

GEAR DISAGREE WARNING MESSAGE WHILE SELECTING GEAR DOWN.  NOSE GEAR SHOWED DOWN POSITION WHILE MAIN GEAR REMAINED IN UP POSITION. MESSAGE CLEARED DURING GO AROUND. ALL THREE SHOWED DOWN. COMPLIED WITH QRH. (FLT 5135, FILED CLOSED)UPON ARRIVAL TO A/C FOUND PSEU FLAGGED SOV NEAR, AND DI20 ON.  PER FDR DOWNLOAD DATA AND THE FLEET COORDINATOR, THE REASON THE SOV NEAR IS PROBABLY BECAUSE IT IS PART OF THE SPIN DOWN AND THE PARKING BRAKE SOV IS CLOSED WITH THE PARKING BRAKE SET. FLEET COORDINATOR SUGGESTS MLG SELECTOR VALVE TO BE FAULTY.  REF CP-1141413 FOR THE MLG SELECTOR VALVE REMOVAL AND REPLACEMENT.  PERFORMED AN OPERATIONAL CHECK OF THE LANDING GEAR EXTENTION AND RETRACTION IN REFERENCE TO CRJ200 AMM 32-30-00.  OPS CHECK GOOD.
