## Discrepancy

DURING CLIMB OUT, THE PILOT REPORTED THAT DURING THE LG RETRACTION THE RED IN TRANSIT LIGHT REMAINED ILLUMINATED & THE LG WOULD NOT FULLY RETRACT.  THE PILOT ATTEMPTED TO EXTEND THE LG & THE LG WOULD NOT EXTEND NORMALLY.  THE PILOT EXTENDED THE LG USING THE EMER EXTENSION SYS & RECEIVED A SAFE DOWN & LOCKED INDICATION.  RETURNED & LANDED WITHOUT INCIDENT.  TROUBLE SHOT THE LG SYS & FOUND THE RT MLG WEIGHT ON WHEELS SQUAT, SWITCH PN 444EN49-6, INTERNALLY SHORTED CAUSING THE LG GEAR CONTROL CB TO TRIP.  THE RT MLG WEIGHT ON WHEELS SWITCH WAS REPLACED & LG SWINGS COMPLETED ON JACKS.  THE LG SYS FUNCTIONAL CHECKED NORMAL.
