## Discrepancy

(CAN) AIRCRAFT ARRIVED WITH NOSE LANDING GEAR FLAT. ATTEMPTS TO RESERVICE OLEO FAILED DUE TO RAPID LEAKING. UPON INVESTIGATION IT WAS FOUND THAT THE INNER PISTON TUBE ASSEMBLY WAS CRACKED AT ITS LOWER FLANGE ALLOWING FLUID AND NITROGEN TO ESCAPE. TUBE ASSEMBLY REPLACED, AIRCRAFT RETURNED TO SERVICE.
