	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 Propellers Alert Service Bulletin (ASB) ASB255A dated6 October 2008.
	Note 2: If there is any question as to the acceptability of a blade shank "step condition'', the ability to accurately measure 0.005-inch wear or the acceptability of any other wear present, the Civil Aviation Safety Authority recommends that you contact McCauley Product Support at McCauley Propeller Systems, 5800 E. Pawnee, Wichita, KS 67218, telephone 0011 1 316 831 4021 for guidance.
	7. If, as a result of the Requirement 6 fluorescent penetrant inspection, one or more propeller blades are found cracked on a propeller assembly remove from service all of the propeller blades and the propeller hub. 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.
	8. If, as a result of the Requirement 6 visual inspection for a "step condition'' of the blade shank, remove from service all propeller blades that exhibit a blade shank "step condition'' of 0.005-inch or greater. Blades removed from service are prohibited from installation in any configuration on any airframe.
	9. Remove from service all C-5963 split retainers at the time of blade inspection specified in Requirement 6. C-5963 split retainers removed from service are prohibited from installation in any configuration on any airframe.
	10. Propeller assemblies with C-5963 split retainers may not be installed on any airframe.
