Narrative:
N52DC was climbing through FL280 when the flight crew felt a 'violent shudder' in the airframe and observed indications of a left engine failure. Visual examination of the left engine revealed the fan section had separated (uncontained failure/tearaway). The airplane was landed without further incident. A post-accident examination of the parts revealed the fan disc failed catastrophically due to low cycle fatigue.

Probable Cause:

PROBABLE CAUSE: "Catastrophic failure of the left engine fan disc due to low cycle fatigue."
