Narrative:

Maximum power selected and attained (2.01/91%); ord runway 32L/T10; 132000 pounds with approximately 3 KTS of tailwind. At the 80 KT call power was stabilized; but shortly thereafter; left engine EPR began to slowly wind down. I slowly advanced the left throttle in an attempt to maintain EPR with no response. The left engine EPR then rapidly began to wind down with an associated egt spike. The takeoff was aborted at approximately 110 KTS (V1 was 135 KTS) with the left engine egt reaching approximately 650 C for 1 second at its peak. 1.50 EPR was set prior to brake release to help offset our slight tailwind; which aided available stopping distance during the abort. Brake temperature never exceeded 200 degrees C. No assistance was required from ord local. Ramp; tower; and maintenance were notified and the flight returned to the gate.callback conversation with reporter revealed the following information: the reporter stated this airplane had previous write ups on the left engine trim. The left engine fuel control was replaced and reported to have fixed the loss of power and the trim problems. Callback conversation with acn 682482 revealed the following information: the reporter had no further information on the cause of the loss of power on the left engine at this time.

Title: AN MD80 ABORTED TKOF AT 110 KTS DUE TO LOSS OF POWER #1 ENG. PRESSURE RATIO DROPPED WITH ASSOCIATED RISE IN EXHAUST GAS TEMP.

Narrative: MAX POWER SELECTED AND ATTAINED (2.01/91%); ORD RWY 32L/T10; 132000 LBS WITH APPROX 3 KTS OF TAILWIND. AT THE 80 KT CALL POWER WAS STABILIZED; BUT SHORTLY THEREAFTER; L ENG EPR BEGAN TO SLOWLY WIND DOWN. I SLOWLY ADVANCED THE L THROTTLE IN AN ATTEMPT TO MAINTAIN EPR WITH NO RESPONSE. THE L ENG EPR THEN RAPIDLY BEGAN TO WIND DOWN WITH AN ASSOCIATED EGT SPIKE. THE TKOF WAS ABORTED AT APPROX 110 KTS (V1 WAS 135 KTS) WITH THE L ENG EGT REACHING APPROX 650 C FOR 1 SECOND AT ITS PEAK. 1.50 EPR WAS SET PRIOR TO BRAKE RELEASE TO HELP OFFSET OUR SLIGHT TAILWIND; WHICH AIDED AVAILABLE STOPPING DISTANCE DURING THE ABORT. BRAKE TEMP NEVER EXCEEDED 200 DEGS C. NO ASSISTANCE WAS REQUIRED FROM ORD LOCAL. RAMP; TWR; AND MAINT WERE NOTIFIED AND THE FLT RETURNED TO THE GATE.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THIS AIRPLANE HAD PREVIOUS WRITE UPS ON THE L ENG TRIM. THE L ENG FUEL CTL WAS REPLACED AND RPTED TO HAVE FIXED THE LOSS OF POWER AND THE TRIM PROBLEMS. CALLBACK CONVERSATION WITH ACN 682482 REVEALED THE FOLLOWING INFO: THE RPTR HAD NO FURTHER INFO ON THE CAUSE OF THE LOSS OF POWER ON THE L ENG AT THIS TIME.
