## Discrepancy

LOSS ALL RIGHT HYD QUANTITY.  RT SYS SHOWS ZERO ON EICAS.  GAUGE AT SVC PANEL ALSO ZERO FOR RT SYSTEM.  FOUND NO EVIDENCE OF HYD LEAK AFTER OPERATING ALL SYSTEMS.  SITE GAUGE FOUND RESERVOIR TO BE SERVICED TO BOTTOM OF SIGHT GAUGE.  PER MEL SERVICED TO TOP OF SIGHT WINDOW OF RT RESERVOIR.  RAN RT ENG AND CYCLED ALL FLT CONTROLS AND CONFIRMED NO LEAKS AND FLUID LEVEL STILL SERVICED TOP OF WINDOW.  REPLACED RT HYDRAULIC QUANTITY TRANSMITTER.  REFILLED SYSTEM, OPS CHECK OKAY.
