## Discrepancy

(CAN) AFTER TAKE-OFF AND ON GEAR UP SELECTION, THE NOSE GEAR FAILED TO RETRACT AND IT WAS OBSERVED BY THE CREW THAT THE NR 2 HYDRAULIC SYSTEM WAS ALMOST DEPLETED OF OIL. AIRCRAFT WAS MAINTAINED VISUALLY IN THE CIRCUIT WHILE ALL RELEVANT QRH PROCEDURES WERE COMPLETED. FOLLOWING COMPLETION OF DRILLS A NORMAL APPROACH AND LANDING WAS CARRIED OUT. ENGINEERING INVESTIGATION REVEALED A RUPTURE FAILURE OF A FLEXIBLE HOSE IN THE NLG RETRACTION HYDRAULIC SYSTEM.  THE HOSE WAS REPLACED AND FOLLOWING SATISFACTORY COMPLETION OF MM REQUIREMENTS THE AIRCRAFT WAS RELEASED TO SERVICE WITHOUT FURTHER INCIDENT.
