## Discrepancy

ABORTED TAKEOFF THE PILOT ABORTED TAKEOFF AS HE SAW THE ENGINE TEMPERATURE RISE TO 810C. THE AIRCRAFT RETURNED TO THE RAMP WHERE TROUBLESHOOTING ISOLATED THE PROBLEM TO A FAULTY HANDLING BLEED VALVE SERVO IN WHICH A PIECE OF METAL WAS OBSTRUCTING THE ORIFICE, AND PREVENTING THE VALVE FROM CLOSING.  THE SERVO WAS REPLACED AND THE AIRCRAFT RETURNED TO SERVICE.
