## Discrepancy

THE AIRCRAFT LOST NR 3 HYDRAULIC SYSTEM FLUID WHILE EN ROUTE.  THE AIRCRAFT WAS RETURNED TO IAH WHERE IT LANDED WITHOUT INCIDENT.  INITIAL FINDINGS REVEALED THE LT MLG SUPPORT FRAME ASSEMBLY WAS BROKEN.  *S/D*  FAILURE OF THE SUPPORT FRAME ASSEMBLY RESULTED IN DAMAGE TO THE HYDRAULIC LINES AND SUBSEQUENT LOSS OF HYDRAULIC FLUID FROM THE NR 3 SYSTEM.  THE HYDRAULIC LINES AND LT MLG RETRACT ACTUATOR WERE REPLACED.  THE LT MLG SUPPORT FRAME ASSEMBLY, SUPPORT FITTING, AND ASSOCIATED DAMAGED HARDWARE WERE REMOVED AND REPLACED.
