## Discrepancy

(CAN) DURING APPROACH THE PILOT NOTICE THAT THE NLG WAS INDICATING UP ALTHOUGH THE PILOT WAS ABLE TO VERIFY THE NOSE GEAR WAS DOWN.  AFTER A NORMAL LANDING IT WAS DISCOVERED THAT THE NLG UPLOCK SWITCH STRIKER ASSY HAD BECOME SEIZED IN THE BULKHEAD OF THE FUSELAGE NOSE STRUCTURE WHERE IT SITS. THE STRIKER WAS FREED WITH LUBRICATED WHICH ALLOWED THE NOSE GEAR TO INDICATE CORRECTLY.
