## Discrepancy

EN ROUTE FROM BOS-BWI, THE REAR BAY OVERHEAT LIGHT ILLUMINATED. ENGINE POWER WAS REDUCED AND THE LIGHT EXTINGUISHED.  POWER WAS REAPPLIED AND THE LIGHT DID NOT ILLUMINATE.  THE AIRCRAFT DIVERTED TO OXC AS A PRECAUTION AND LANDED WITHOUT INCIDENT.  THE AIRCRAFT REAR BAY WAS INSPECTED WITH NO DAMAGE FOUND.  A GROUND RUN OF THE AIRCRAFT WAS PERFORMED.  THE REAR BAY LIGHT DID NOT ILLUMINATE, BUT A SMALL LEAK WAS DETECTED FROM THE FLOW CONTROL VALVE.  THERE IS A HEAT DETECTOR IN CLOSE PROXIMITY TO THE VALVE.  OPS CHECKED REAR EQUIPMENT BAY HEAT DETECTORS IAW MM 26-10 TEST B CHECKED GOOD.  THE VALVE SEALS WERE CHANGED, THE AIRCRAFT WAS RUN AT HIGH POWER WITH ALL SYSTEMS NORMAL AND NO LEAKS.  THE AIRCRAFT WAS RETURNED
