## Discrepancy

DURING ROUTINE ENGINE CHANGE, A VISUAL INSPECTION OF COMPONENTS REVEALED THAT THE RT ENGINE HYDRAULIC PRESSURE LINE WAS LOOSE AT THE PYLON. THE JAMB NUT WAS NOT TIGHTENED CORRECTLY, ALLOWING THE LINE TO CHAFFE IN TO THE SKIN OF THE PYLON SKIRT. THERE WAS NO DAMAGE TO THE PYLON SKIN. THE LINE WAS DAMAGED BEYOND REPAIR, AND REPLACED WITH A NEW COMPONENT.
