Narrative:
A CFI WAS INSTRUCTING AN INSTRUMENT RATED COMMERCIAL PILOT. DURING A PRACTICE MISSED APPROACH, THE LANDING GEAR FAILED TO RETRACT. THE CREW ATTEMPTED TO LOWER THE LANDING GEAR USING ALL AVAILABLE EMERGENCY PROCEDURES. A FLY-BY THE TOWER REVEALED THAT THE MAIN GEARS WERE DOWN WHILE THE NOSE LANDING GEAR WAS IN TRANSIT. DURING LANDING ROLLOUT, THE NOSE GEAR COLLAPSED AS SOON AS IT MADE CONTACT WITH THE RUNWAY. THE GEAR MALFUNCTION WAS THE RESULT OF A RUPTURED HYDRAULIC FLUID LINE. THE DEPLETION OF THE HYDRAULIC FLUID RENDERED THE LANDING GEAR SYSTEM INOPERABLE.
