## Discrepancy

AFTER TAKEOFF, CREW SELECTED GEAR UP, THE LANDING GEAR DID NOT RETRACT.  AFTER ABOUT ONE MINUTE THE LANDING GEAR RETRACTED. IMMEDIATELY FOLLOWING THE RETRACTION THE HYD PRESS 2 CAUTION LIGHT ILLUMINATED, THE NR 2 HYDRAULIC FLUID QUANTITY WAS RAPIDLY DECREASING AND HYDRAULIC PRESSURE WENT TO ZERO. THE CREW THEN CARRIED OUT AN ALTERNATE GEAR EXTENSION AND RETURNED BACK TO BASE, WHERE A NORMAL LANDING WAS MADE.  INITIAL INVESTIGATION OF THE AIRCRAFT FOUND A LARGE HYDRAULIC LEAK COMING FROM THE RT WING ROOT AREA.  THE SOURCE OF THE LEAK WAS TRACED TO THE SEPARATION OF THE PTU.
