## Discrepancy

DURING CLIMBOUT OF KIAD, GEAR WENT FROM DOWN AND LOCKED TO UP AND LOCKED WITHOUT A TRANSIT INDICATION.  CREW THEN RETURNED A/C TO KIAD FOR MAINTENANCE TO TROUBLESHOOT.  MAINTENANCE INSPECTED AND FOUND THAT THE RIGHT MLG UPLOCK NR 2 PROX SWITCH BAD.  REMOVED AND REPLACED AND PERFORMED OPS CHECK OF LANDING GEAR GOOD.
