Narrative

DURING TKOF ROLL AT APPROX 40 KTS JUST AFTER ENGS HAD REACHED FULL THRUST (FULL THRUST USED DUE TO DISPATCH ITEM CONCERNING FLAP FAIRING); THERE WAS A LOUD BANG ON THE L SIDE OF THE AIRPLANE. THIS WAS FOLLOWED BY A LOSS OF THRUST AND YAWING TO THE L. THE GROSS WT WAS APPROX 763000 LBS AND THE CAPT WAS AT THE CTLS; SINCE THE ACFT WAS BELOW REJECTED TKOF SPD OF 85 KTS MANUAL BRAKING AND NORMAL ABORTED TKOF PROCS WERE USED. THIS INCIDENT WAS JUST AS WE PRACTICE IN THE SIMULATOR. THE FLYING FO INITIALLY ASSISTED THE CAPT IN BRAKE APPLICATION. THE ACFT NEVER EXITED THE RWY SURFACE. IT ACTUALLY ONLY GOT APPROX 1/2 WAY FROM THE RWY CTRLINE TO THE EDGE OF THE RWY.
