## Discrepancy

WHEN GEAR PLACED DOWN, NOSE WHEEL GREEN LIGHT WOULD NOT ILLUMINATE.  PRESS TO TEST GOOD.  CYCLED GEAR AND GOT A GREEN DOWN AND LOCKED LIGHT.  AFTER TROUBLESHOOTING SYS, SUSPECT NOSEGEAR POS SWITCH AS BEING BAD.  ORDERED PT AND PT N.I.S.  REMOVED ARM FROM LOCK SWITCH AND CKD WITH METER MANY TIMES NO FAILURES NOTED.  REMOVED ARM FROM POS SWITCH AND CKD WITH METER WHILE OPERATING MANY TIMES.  NO PROBLEMS FOUND.  OPERATE SWITCHES WHILE VIEWING POSITION LIGHTS.  ALL POSITIONS  NORMAL.  COULDN'T DUPLICATE ITEM.  POSITION LIGHTS OK FOR SERVICE.
