Narrative:

After leveling at 11000 ft; the #2 engine shut down without any signs or warning. The first officer was flying the leg; but her 120 hours of experience in the jet was such that I suggested that I take the aircraft and she refer to the cfm. An in-flight re-light was unsuccessful; an emergency was declared and the approach and landing were uneventful. The company maintenance was called upon arrival at gate. Subsequent inspection visually of the engine revealed no FOD or casing penetration. 24 hours later; I was told that the accessory drive gear shaft sheared on the right engine. Company had to replace the engine.
