The elevator has 3 non-bearing hinges same as rudder. I would think that the elevator would not be "airworthy" knowing what we know now about the kr hinges.
Steven, The stock hinges are perfectly airworthy, based on all the flying KR series aircraft flying with them, unless your projects has a defective in installation. My own plane has just under 300 hours on the stock hinges and they are working fine. If you want to replace them because DR. Dean's hinge idea is better (which I agree it certainly is) this is the time to do it. If this is not a hill to die on, you might want to go ahead and use the hinges that are already installed. I have no doubt my hinges will need to be replaced on the elevator eventually, probably in another 150-200 hours or so. I will cross that bridge when it is before me.
