## Discrepancy

AFTER TAKEOFF, ON GEAR RETRACTION THE NOSE GEAR RETRACTED NORMALLY, BOTH MLG REMAINED GREEN & GEAR DOOR LIGHTS ILLUMINATED RED.  WHEN GEAR HANDLE MOVED TO THE GEAR DOWN POSITION ALL 3 GEARS SHOWED DOWN AND GREEN AND THE RED GEAR DOOR LIGHTS WERE EXTINGUISHED.  REPLACED NLG PROXIMITY DETECTOR (5GBC) WITH A REPAIRED UNIT IAW MM 32-600. OPS CHECKED GOOD.
