## Discrepancy

During Flight #3610, Nose gear would not retract after Takeoff.  Red Transition light on handle and Indicator.  Air Turnback to MSP.  Maintenance found uplock Proximity sensor bad.  Replaced Proximity switch PN 8-018-01.  IAW AMM 32-60-21.  Ops checks of switch and gear swings all good.
