Background:  This AD results from the discovery of a five-bladed propeller hub with a large crack on the mounting flange of the hub.  It was determined that the hubs at risk are in two populations.  The first population is those hubs with unknown hours, or with between 1,800 and 4,500 hours TIS.  The second population is all other hubs with fewer than 1,800 or more than 4,500 hours TIS.
