Analysis
While performing a snaproll at an airshow, the crankshaft failed & the prop separated from the acft. The plt landed on the arpt, but the acft went thru an open hanger before the plt could stop. The wings struck supporting poles under the roof of the hanger. An exam revealed that the cranshaft had failed from fatigue.
