What was found
THE HYDRAULIC PRESSURE LINE FROM THE PUMP HAD FAILED. THE CLAMP THAT SECURES THE HOSE TO THE PYLON DECK HAD CHAFED INTO THE STEEL BRAIDING OF THE LINE, CAUSING A WEAK POINT IN THE LINE, AND THE WALL OF THE HOSE TO RUPTURE THROUGH THE BRAIDING. THUS CAUSING A TOTAL HYDRAULIC FAILURE. THE CAUSE OF THE HOSE FAILURE IS THE ALIGNMENT OF THE CLAMP ON THE HOSE.
