We have major rivet wear on an aluminum rudder for a marine hovercraft. The rivets are blind protruding head mechanically locked spindle type NAS 1738-5 and 6. Is there damage limits to clarify allowable damage to the rivet heads and formed rivet ends due to service wear?

If you are not refering to wear to the heads, there there shouldn't be any wear. If there is wear on the shanks, you have a bad joint. Requiring repair, not matter what.

Your situation might be a good application for a friction drilled hole. This process is great for blind holes and eliminating riv-nuts and other fasteners. Just a thought.
