      5. Remove from service any propeller blades and hubs found or documented to have been installed in any propeller assembly that has had one or more cracked propeller blades at any time.  Propeller blades and the propeller hub of a propeller assembly that has had one or more cracked propeller blades are prohibited from installation in any configuration on any airframe.
      6. Perform a fluorescent penetrant inspection and eddy current inspection of the propeller blades, together with a visual inspection for a "step condition'' of the blade shank.  Use the Equipment Required and Accomplishment Instructions of McCauley
