## Discrepancy

(CAN) AFTER T/O CREW WERE UNABLE TO SELECT GEAR UP. WITH GEAR SELECTOR IN UP POSITION THEY HAD NO YELLOW DOOR LIGHTS AND STILL 3 GREENS AND 3 REDS AND LEVER TRANSIT LIGHT. THEY SELECTED LEVER DOWN, BRIEFED CREW AND PAX AND RETURNED TO BASE FOR NORMAL LANDING.  INVESTIGATION/ACTION THE UNABILITY TO RETRACT LANDING GEARS WAS CAUSED DUE BREAKAGE OF THE NOSE WHEEL CENTERING PROXIMITY SENSOR WIRES.  NOSE WHEEL CENTERING SENSOR REPLACED IAW AMM 32-61-00.
