Narrative:

On takeoff roll at jax #1 throttle was much further forward than #2 or #3. Maximum power was selected . At this setting, #1 engine EPR read 1.88 with #1 throttle at forward throttle stop. Maximum required EPR was 1.99 and both #2 and #3 engine produced this EPR west/O reaching throttle stop. At maximum power setting, left duct pressure was 51 psi, right was 62 psi. Takeoff was discontinued at less than 60 KIAS and normal taxi back to gate. No emergency equipment was requested. Upon gate arrival, a large hole was visible on upper #1 engine cowl. Maintenance found ruptured 6TH stage manifold. Jax airport authorities swept runway 25 and found pieces of the engine cowl. For some unknown reason, it was reported to us that the FAA miami region received a hotline report on this incident.

Title: ACR LGT TKOF ABORT DUE LOW POWER ON #1 ENGINE.

Narrative: ON TKOF ROLL AT JAX #1 THROTTLE WAS MUCH FURTHER FORWARD THAN #2 OR #3. MAX PWR WAS SELECTED . AT THIS SETTING, #1 ENG EPR READ 1.88 WITH #1 THROTTLE AT FORWARD THROTTLE STOP. MAX REQUIRED EPR WAS 1.99 AND BOTH #2 AND #3 ENG PRODUCED THIS EPR W/O REACHING THROTTLE STOP. AT MAX PWR SETTING, LEFT DUCT PRESSURE WAS 51 PSI, RIGHT WAS 62 PSI. TKOF WAS DISCONTINUED AT LESS THAN 60 KIAS AND NORMAL TAXI BACK TO GATE. NO EMER EQUIP WAS REQUESTED. UPON GATE ARR, A LARGE HOLE WAS VISIBLE ON UPPER #1 ENG COWL. MAINT FOUND RUPTURED 6TH STAGE MANIFOLD. JAX ARPT AUTHORITIES SWEPT RWY 25 AND FOUND PIECES OF THE ENG COWL. FOR SOME UNKNOWN REASON, IT WAS RPTED TO US THAT THE FAA MIAMI REGION RECEIVED A HOTLINE RPT ON THIS INCIDENT.
