## Discrepancy

ON 6/10/25 (680-0064, N413CK) WAS ON A FLIGHT TO TEXTRON AVIATION (KSMF) FOR SCHEDULED MAINTENANCE GOT A “HYD LOW CAS” MESSAGE, THEY WERE ABLE TO EXTEND THE GEAR NORMALLY BUT DURING LANDING THEY ENDED UP STOPPING ON THE RUNWAY WITH A PUDDLE OF HYDRAULIC FLUID UNDER THE PLANE. WE WENT OUT AND CLEANED UP THE FLUID FROM THE RUNWAY AND TOWED THE AIRCRAFT TO OUR HANGAR. WHAT WE FOUND WAS THAT THE NOSE STEERING PRESSURE HOSE RUPTURED NEAR ONE OF THE END FITTINGS. THESE HOSES ARE 5000 HOUR TIME CHANGE ITEM AND THIS ONE FAILED AT 3634.8 HOURS.
