Rudder Bottom Fairing

I was installing the R-911 rudder bottom fairing today and expected it to be fastened by CS4-4 blind rivets as it was on the RV-7A. The plans, however, call for nut plates and -6 screws. I would prefer to use the blind rivets and make the installation permanent. Is there anything different about the RV-14 which would make it necessary to have the fairing removable?

Customer preference.

It is one of the most commonly damaged parts on the airplane. As a result, a lot of past builders have chosen to install it with screws, so that was standardized for the 14 kit.

What he said. My second one went on with platenuts and screws.
