Narrative:

Flight was scheduled dfw-ege. Upon review of the logbook the first officer noted that the aircraft had 2 entries in recent days that right engine was unable to attain maximum power on takeoff. Since we were going to ege and return I decided to do a maximum power takeoff at dfw to ensure that the engine would perform properly. On takeoff maximum power was set. With the autothrottles both engines stopped above standard power, but short of maximum power. The throttles were manually advanced. The left engine reached the proper level but the right did not reach the maximum power level. By this time the aircraft was accelerating rapidly and was approaching V1. I did not consider a high speed abort was necessary since both engines were operating above standard power. A normal takeoff was accomplished. After cleanup departure control was notified that we would be returning to dfw to land after burning fuel to below maximum landing weight. Dispatch was notified and concurred with this plan of action. After approximately 40 mins of flying a normal landing was accomplished with no special handling required. The aircraft was replaced and the trip continued to ege.

Original NASA ASRS Text

Title: B757 FLC UNABLE TO ATTAIN MAX PWR ON TKOF. THEY BURN FUEL AND RETURN LAND.

Narrative: FLT WAS SCHEDULED DFW-EGE. UPON REVIEW OF THE LOGBOOK THE FO NOTED THAT THE ACFT HAD 2 ENTRIES IN RECENT DAYS THAT R ENG WAS UNABLE TO ATTAIN MAX PWR ON TKOF. SINCE WE WERE GOING TO EGE AND RETURN I DECIDED TO DO A MAX PWR TKOF AT DFW TO ENSURE THAT THE ENG WOULD PERFORM PROPERLY. ON TKOF MAX PWR WAS SET. WITH THE AUTOTHROTTLES BOTH ENGS STOPPED ABOVE STANDARD PWR, BUT SHORT OF MAX PWR. THE THROTTLES WERE MANUALLY ADVANCED. THE L ENG REACHED THE PROPER LEVEL BUT THE R DID NOT REACH THE MAX PWR LEVEL. BY THIS TIME THE ACFT WAS ACCELERATING RAPIDLY AND WAS APCHING V1. I DID NOT CONSIDER A HIGH SPD ABORT WAS NECESSARY SINCE BOTH ENGS WERE OPERATING ABOVE STANDARD PWR. A NORMAL TKOF WAS ACCOMPLISHED. AFTER CLEANUP DEP CTL WAS NOTIFIED THAT WE WOULD BE RETURNING TO DFW TO LAND AFTER BURNING FUEL TO BELOW MAX LNDG WT. DISPATCH WAS NOTIFIED AND CONCURRED WITH THIS PLAN OF ACTION. AFTER APPROX 40 MINS OF FLYING A NORMAL LNDG WAS ACCOMPLISHED WITH NO SPECIAL HANDLING REQUIRED. THE ACFT WAS REPLACED AND THE TRIP CONTINUED TO EGE.
