NTSB Narrative Summary Released at Completion of Accident
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.
NTSB Probable Cause Narrative
the loss of right engine power as a result of a fatigue failure of the propeller shaft coupling.
