## Discrepancy

(CAN) AFTER A MAINTENANCE RUN, THE ENGINEER NOTICED A HYDRAULIC LEAK FROM THE LEFT WHEEL WELL. UPON FURTHER INVESTIGATION, IT WAS DETERMINED THAT THE LEAK WAS COMING FROM THE MLG DOWN PRESSURE LINE (RIGID TUBE) IN THE LEFT NACELLE DUE TO A PIN HOLE IN THE TUBE. THE TUBE WAS REPLACED AND ALL FURTHER CHECKS WERE COMPLETED PRIOR TO RETURNING THE AIRCRAFT TO SERVICE.
