## Discrepancy

RIGHT HAND HPSOV EICAS MESSAGE LIGHT CAME ON DURING FLIGHT. COMPLIED WITH QRH AND RETURNED TO DEPARTURE. EMERGENCY DECLARED, AIRCRAFT LANDED.  THE AIRCRAFT WAS GROUNDED.  REPLACED HIGH PRESSURE SHUT-OFF VALVE AND HIGH PRESSURE SHUT-OFF VALVE CONTROLLER AS A PRECAUTION PER AMM 36-11-07 AND 36-11-08. HIGH POWER ENGINE RUN PERFORMED. ALL PARAMETERS FOUND TO BE NORMAL. NO MESSAGE NOTED AT THIS TIME. OK FOR SERVICE. THIS SDR IS FOR THE HIGH PRESSURE SHUT-OFF VALVE.
