Compressor assembly,blade - fatigueCause
Compressor assembly,rotor disc - disabledCause

Analysis

During takeoff on a regularly scheduled passenger flight the aircraft sustained a total engine failure and flameout on the right engine. After securing the engine, the crew executed an uneventful single engine landing without further damage to the aircraft or injuries to persons. 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. Subsequent metallurgical examination indicated that one of the compressor blades had failed in fatigue. The origin of the fatigue fracture was in the area of the root trailing edge. The reason for the fatigue initiation could not be determined.
