Compressor assembly,blade - fatigueCause

Analysis

During cruise flight, the aircraft experienced a power failure and fire in the left engine. The crew secured the engine and discharged the fire extinguisher without effect on the fire. During descent to jfk international the fire extinguished itself. A normal single engine landing was made and the passengers deplaned without injury. Investigation revealed that a compressor turbine blade had failed in fatigue damaging power turbine blades, the power turbine vane ring and the compressor turbine vane ring. In addition the propeller reduction gearbox was damaged. The origin and nature of the fatigue in the turbine blade was not determined. It was determined that the failed blade was installed at overhaul, about 843 hours before the incident.
