Narrative:The aircraft was taking off from runway 27L when the nr.2 engine separated. It fell to the ground 800 feet past the end of the runway. The crew managed to climb to 1000 feet before they initiated a return to the airport for a safe emergency landing on runway 04R.
PROBABLE CAUSE: "Previous damage to the aft cone (engine mounting) bolt, which resulted in mismatched surfaces between the bolt and isolation mount, loss of torque during cyclic loading of the mounting bolt, and subsequent fatigue failure of the bolt."
