Narrative:
During takeoff roll, normal takeoff power was set. The #3 engine EPR stopped approximately 0.10 short of takeoff power setting with full forward travel of throttle. All other parameters were similar to engines #1 and #2. Takeoff was accomplished without incident. In retrospect, an abort of takeoff might have been appropriate. However, I felt that the engine was developing adequate power for conditions. Additionally, by the time it was determined that the #3 engine was not developing proper EPR, speed had increased to a point that would have necessitated a relatively high speed, high gross weight abort.
Original NASA ASRS Text
Title: ACR LGT EXPERIENCES A REDUCED EPR READING ON #3 ENG AND FLC ELECTS TO NOT ABORT TKOF FOR THIS ACFT EQUIP PROBLEM.
Narrative: DURING TKOF ROLL, NORMAL TKOF PWR WAS SET. THE #3 ENG EPR STOPPED APPROX 0.10 SHORT OF TKOF PWR SETTING WITH FULL FORWARD TRAVEL OF THROTTLE. ALL OTHER PARAMETERS WERE SIMILAR TO ENGS #1 AND #2. TKOF WAS ACCOMPLISHED WITHOUT INCIDENT. IN RETROSPECT, AN ABORT OF TKOF MIGHT HAVE BEEN APPROPRIATE. HOWEVER, I FELT THAT THE ENG WAS DEVELOPING ADEQUATE PWR FOR CONDITIONS. ADDITIONALLY, BY THE TIME IT WAS DETERMINED THAT THE #3 ENG WAS NOT DEVELOPING PROPER EPR, SPD HAD INCREASED TO A POINT THAT WOULD HAVE NECESSITATED A RELATIVELY HIGH SPD, HIGH GROSS WT ABORT.
