Read the full NTSB narrative
The 1,911-hour certificated flight instructor reported that while in cruise flight, the propeller separated from the engine. The instructor stated that just prior to the propeller separating from the engine, he noticed a light oil spray covering the windscreen. The instructor then took control of the airplane and executed a forced landing to a nearby airport without further incident. The owner of the airplane reported that he was not aware of any anomalies leading to the failure of the propeller assembly, there were no pre-existing vibrations, no propeller changes, and to his knowledge, "no prior incursion or indications of this occurrence." Examination of the engine revealed that the crankshaft separated aft of the propeller flange. A metallurgical examination of the fractured area of the crankshaft revealed the fracture (consistent with fatigue) within the nitrided layer of the crankshaft originated from a small circumferential crack (consistent with overload) and progressed to the identification stamp. The origination from the original crack is undetermined.
