## Discrepancy

FLT 1325 - BWD - DURING CLIMB-OUT, THE RIGHT WING OVERHEAT LIGHT CAME ON.  THE LIGHT WENT OUT WHEN LANDING GEAR WAS EXTENDED FOLLOWING THE EMERGENCY CHECKLIST.  CREW RETURNED TO STATION.  NO APPARENT MECHANICAL CAUSE.  THIS TEMP SENSOR IS LOCATED IN THE WHEEL WELL FORWARD OF THE MASS FLOW VALVE, APPROXIMATELY THE LEADING EDGE OF THE TIRES.  IF THE BRAKES WERE HOT, AND FULL HEAT IS SELECTED, IT IS POSSIBLE THAT THE COMBINATION OF HEAT SOAKED BRAKES AND THE HOT BLEED AIR IN THE BLEED AIR LINE GOING TO THE MASS FLOW VALVE REACHED THE TRIP POINT FOR THE WING OVERHEAT SENSOR.  MAINTENANCE WAS DISPATCHED, INSPECTED WINGS FOR SIGNS OF OVERHEAT, BLEED AIR LEAKS, AND DAMAGED WIRING.  NONE WAS FOUND.  NO FURTHER DISCREPA
