## Discrepancy

AFTER TAKEOFF, PASSING 10,000' (WITH NO DEMAND ON ANY HYDRAULIC SYSTEMS) THE LOW HYD FLOW R ANNUNCIATOR ILLUMINATED. CONTINUED THE CLIMB TO FL250. 15 MINUTES LATER, DURING DESCENT THRU FL230 THE LIGHT EXTINGUISHED AND DID NOT REOCCUR. ALL HYDRAULIC SYTEMS WORKED NORMALLY DURING THE REMAINDER OF APPROACH AND LANDING.  R & R THE RIGHT HYD SYSTEM "LO HYD FLOOR" SWITCH IAW MM 29-11-04. INSPECTION OF THE RT HYD SYS FILTER SHOWED NO CONTAMINATION OPS AND LEAK CHECKS ARE GOOD.
