Today, my RV-9 buddy had one. He probably has < 30 hours in phase 1 and went flying this morning. About a 60 mile round trip and on the way home, subtle engine surges followed by rough running and fuel smell. Dead sticked into home base, and put the plane away. Cowl removed. Failure easy to diagnose. Two nuts that should be holding the fuel servo tightly to the engine were laying in the lower cowl, and the other two were loose. Real loose. No torque seal in evidence, so the nuts may not have been torqued down to start with. So, I looked at my install (not flying yet and untorqued) and, like his, I have nuts holding the servo on, but no locking nuts, lock washers or safety wire. This begs the question ..... what have others done when attaching the fuel servo?? I've already had my 3 'oh craps' and don't want to risk another!!!!

So far in 275 hours they haven't moved. Nordlock washers might work great here. I first saw these on my Matco brakes, then someone posted this impressive video: http://www.nord-lock.com/bolted/watch-the-new-junker-test-video-here/ Don't forget to safety wire the bolts holding the FAB mounting plate to the fuel servo. Glad your buddy is ok.
