Incident Overview
During the takeoff phase of a regularly scheduled passenger flight, the aircraft experienced a total failure and flameout of the right engine. The crew secured the affected engine and subsequently executed an uneventful single-engine landing. No further damage to the aircraft or injuries to persons occurred.
Engine Examination
Post-incident examination of the engine revealed that the compressor turbine wheel had failed. The internal damage was confined to the wheel, vane ring, shroud, and duct group. Metallurgical analysis determined that one of the compressor blades had failed due to fatigue. The origin of the fatigue fracture was located in the area of the blade root trailing edge. However, the specific reason for the initiation of the fatigue could not be determined.
