## Discrepancy

UPON LANDING GEAR RETRACTION ON DEPARTURE THE CREW NOTED THAT THE NOSE GEAR DID NOT RETRACT.  THE HYDRAULIC LOW PRESSURE ECAS MESSAGE APPEARED ALONG WITH HYDRAULIC VOLUME LOW MESSAGE.  PER THE CHECKLIST THE HYDRAULIC PUMPS WERE BOTH UNLOADED AND THE LANDING GEAR WAS EXTENDED USING THE EMERGENCY PROCEDURE AND AN EMERGENCY LANDING WAS ACCOMPLISHED USING THE EMERGENCY BRAKE HANDLE.  UPON A SUCCESSFUL LANDING THE MAINTENANCE CREW OBSERVED THAT THE NOSE WHEEL STEERING CENTERING HOSE HAD RUPTURED ALLOWING THE FLUID TO ESCAPE.
