## Discrepancy

AIRCRAFT ABORTED TAKEOFF AND RETURNED TO PLATFORM AS A CONSEQUENCE OF THE LEFT ENGINE DID NOT ACCELERATE WITH EPR'S ON 1.4 AND EGT'S LIGHT BLINKING.  WATER TRAMP WAS DRAINED AND ACCELERATION CHAMBER WAS LUBRICATED IAW MM 73-20-03 AND 73-20-01.  DURING ENGINES TEST, EPR INDICATION FAILURE WAS SHOWN.  EPRS TRANSMITTERS WERE INTERCHANGED AND ENGINES WERE TESTED IAW MM 71-00-00, ALL CORRECT.  AIRCRAFT WAS DISPATCHED BUT RETURNED TO PLATFORM AGAIN WITH THE EPR'S INDICATION FAILURE IN THE RIGHT ENGINE.  EPR'S INDICATOR WAS REPLACED IAW MM 77-11-00 AND ENGINES WERE TESTED, ALL CORRECT.
