## Discrepancy

LANDING GEAR WOULD NOT RETRACT AFTER TAKEOFF OUT OF KTEB.  ALL WOW INDICATED AIR MODE EXCEPT COMBINED WOW WHICH WAS AMBER GROUND.  AT 1+03 HOURS AFTER TAKEOFF.  COMBINED WOW WENT TO AIR.  THE GEAR WAS RETRACTED AND ALL SYSTEMS RETURNED TO NORMAL.  A FAULTY WEIGHT ON WHEELS SWITCH.  REPLACED ALL SUSPECTED WEIGHT ON WHEELS SWITCHES AS A PRECAUTION.  SINCE DEFECT COULD NOT BE DUPLICATED.  PERFORMED ALL REQUIRED OPERATIONAL CHECKS IAW MM AND RETURNED AIRCRAFT TO SERVICE.
