the loss of right engine power as a result of a fatigue failure of the propeller shaft coupling.

Read the full NTSB narrative

While in cruise flight, the airplane sustained a contained in-flight right engine failure due to a fatigue failure of the propeller shaft coupling. At a cruise altitude of 9,000 feet approximately 60 miles east of his destination, the pilot heard a "bang." The engine RPM and engine temperature gauges indicated a failure of the right engine. The pilot secured the right engine, declared an emergency to air traffic control, and landed uneventfully. Examination of the propeller shaft coupling revealed a fracture that was caused by a fatigue crack that emanated from the corner radius of a lubrication slot where the corner radius converges with the root of an inner spline. At the time of the engine failure, the engine had accumulated 6,010.2 total hours since overhaul.
