Narrative:
The first officer was performing the takeoff on runway 09L. Takeoff engine thrust was set at 1.42 EPR. All engines operated normally and the aircraft accelerated normally with no unusual vibration felt. Upon reaching the V 1 speed, they heard a loud bang and observed a flash on the right side of the aircraft. The aircraft veered slightly to the right. He, the captain, took control and rejected the takeoff. The flight engineer reported an engine failure. The aircraft was stopped on the runway about 1,000 feet from the departure end. The ATC local controller reported that the No. 4 engine was on fire. They performed the engine fire procedures and fired the engine fire bottles for the No. 4 engine. Airport emergency equipment arrived and extinguished the fire.

PROBABLE CAUSE: "Failure of the No. 4 engine fifth stage turbine hub due to a cyclic stress rupture for undetermined reasons, which resulted in an uncontained failure of the engine"
