## Discrepancy

ON DEPARTURE, AFTER RAISING LG, WE GOT A RED UNLOCK LIGHT.  FOLLOWED THE CHECKLIST, PULLED HYD PRESS CB, & HEARD A CLUNK IN THE NOSE OF THE PLANE, WE BELIEVED THE NOSE GEAR EXTENDED.  BEFORE LANDING WE PUSHED THE CB BACK IN & EXTENDED THE LG.  EXTENSION WAS NORMAL & LANDED UNEVENTFULLY.  FOUND NOSE STRUT NITROGEN PRESS LOW.  CYCLED GEAR SEVERAL TIMES BUT COULD NOT DUPLICATE DISCREPANCY.  R & R NLG NITROGEN SERVICE VLV IAW CE-560XL CMM 32-20-01.  SERVICED NLG STRUT IAW CE-560XL AMM 12-14-00.  LEAK CHECKED GOOD, OPERATIONS CHECKED GOOD.
