After takeoff, a witness observed a puff of black smoke coming from the engine. Shortly thereafter, the airplane nosed down and descended rapidly. During the on-site examination of the engine, it was observed that the #6 cylinder head was separated from the engine. Metallurgical testing on the cylinder head revealed that the fracture was indicative of high temperature separation or overstress.
Probable Cause: The inadvertent stall encountered by the pilot after experiencing an in-flight cylinder head separation.
