I've broken 2 shear screws in my RV-10's roll servo over 4 years and 450ish hours. The original broke a couple years ago and it was chalked up to a weak batch of pins. The second one was one of the newer screws that is supposed to have better fatigue resistance. It broke a couple days ago on a perfectly calm, no turbulence day while doing a practice IFR approach. When the next one breaks I do not have any empty threaded holes in the hub. What is the solution when this happens? With red loctite it is going to be very difficult to remove the threaded stubs. Is field replacement of the hub an option? Can I purchase one and have it in my parts bin?
