I am about ready to start a movement like Nancy Reagan's "just say No to drugs", only mine is going to say "Just say NO to loose jamnuts!"
I thought I had started a thread on this some time ago, but I can't find it right now, so you get to hear me again.
I performed a prebuy on an RV-10 today that has been flying for 8 years. So that's an Airworthiness inspection, and at least 7 Condition Inspections, and amongst the 800 hours, hopefully some preflights.
I found 7 loose jamnuts on the tail surfaces! They had never been tightened, as there was no scoring on the mating surfaces. I just reached in with my fingers and turned them.
So, please go check your jamnuts on your next preflights. This is a high stress area to begin with, with a SB even being issued across most of the models for cracking around the nutplate rivets. Perhaps someone on this forum can set up a poll that says "I have checked my aircraft jamnuts." It would be interesting to see if we could achieve 100% in the next year.
