Analysis

At about the time full power was obtained the heard a loud bang followed by a fire warning for the left engine. The takeoff was aborted and the crew shut down the engine. The passengers were deplaned on the taxiway after it was determined the fire was out & there was no more danger. Examination of the engine revealed that the low pressure impeller failed in a high cycle fatigue mode.
