Executive Summary:Once cleared for take off both engines were set to approximately 55% N1 and when they were stable the commander selected take off power. In the prevailing conditions and using the actual aircraft weight the crew had selected an assumed temperature of +44_C, thus derating the engine power used for take off. Shortly after the first officer had called "Power Set" there was a loud bang and the aircraft swung to the left. Both pilots called "Stop" as the commander closed the thrust levers and the first officer selected reverse idle. As the aircraft decelerated the commander heard the aural warning "Engine Fail" and saw the associated EICAS warning; the master caution light had also illuminated. Once stationary the commander ordered the engine fail drill for the left engine and called for the fire service to attend, he then spoke to the fire chief. Meanwhile the commander had detailed two cabin crew members to monitor the front and rear of the left (No 1) engine for signs of fire. After discussion with the fire crew and ATC it was decided to start the APU and taxi clear of the runway. Since the commander experienced little difficulty in taxying the aircraft on the right engine power only, he elected to continue to the stand, with the fire services following, where the passengers were disembarked. The commander reported that during the engine failure and associated stop he experienced little handling or control problems.

The initial examination showed that the engine had ejected turbine debris into its tailpipe and onto the runway but there was no failure of the engine containment. There had been no secondary damage caused by the engine failure.
