The NTSB released their factual report saying, that the aircraft experienced an uncontained fan blade separation from the right hand engine.

While taxiing to the departure runway the crew had shut the right hand engine down. About 2-3 minutes prior to takeoff the crew restarted the engine and subsequently noticed no anomaly. At about the 80 knots call the crew felt the airplane shudder and observed the right hand engine's exhaust gas temperature (EGT) rise to the red line. The crew rejected takeoff and taxied clear of the runway, responding emergency services detected no fire. The tower advised that there was debris on the runway. The airplane taxied back to the gate, where the occupants deplaned normally.

The examination of the engine revealed, that one fan blade was fractured through the root section, the dovetail section remaining in the fan disk's blade slot. All other fan blades showed hard body damage to their leading edges. Several holes were noticed through the inlet duct, a dent of 3.5 inches (9cm) diameter and 3/8 inches (1cm) depth was found in the fuselage forward of the 2R door just above the windows but below the airline logo.

On Oct 10th 2012 the NTSB released their final report concluding the probable cause of the incident was:

The fan blade fractured due to a fatigue crack that was the result of the combination of the breakdown of the fan blade lubrication system and residual fatigue life usage following the last overhaul of the fan blade. Contributing to the fracture was the inadequate lubrication schedule established by the engine manufacturer that was not reflective of the operatorÂ’s use of the engine.
