## Discrepancy

DURING CLIMB OUT, SLATS RETRACTED NORMALLY.  THEN A MASSIVE HYDRAULIC LEAK APPEARED ON OB LEFT WING.  NR 1 HYDRAULIC SYSTEM BEGAN TO EMPTY.  LANDING GEAR WAS LOWERED AND LANDING WAS MADE NORMALLY.  AFTER INVESTIGATING PROBLEMS WAS LT, OB SLAT ACTUATOR.  THE RETRACTION SWIVEL END FROZE AND IT CAUSED THE HYDRAULIC LINE IN THE LE OF THE OB WING TO BREAK CAUSING THE LEAK.  SB 212 ADDRESSED THIS PROBLEM AND WAS ACCOMPLISHED AT THE FACTORY.  MFG IS LOOKING INTO THE PROBLEM.
