Keith,
there will be many divergent opinions on this I'm sure. My personal mantra is safety wire anything you don't want to fall off! There are several approaches too. I am an ex motorcycle racer and the rules required all basic safety items to be wired. Those were, all oil drains, water drain plugs if any, brake mount bolts, and oil feed bolts and filters. I would usually do more than was required. I have seen many things vibrate off that you wouldn't think possible when operating at high power levels. I would use both .039 and .025 stainless steel safety wire. The .025 isn't FAA approved on a lot of things, but it's light and serves the purpose. I even wired 39°AN fittings, which isn't required.

Subject: [FlyRotary] Safety wire
Hello everyone,
I know that the subject of safety wire has been discussed many times before,
however searching the archives can at times be very difficult and actually
finding the answer you want is like winning the lottery (it never happens).
What I would like to know is what most are considering an absolute must to be
safety wired. What the FAA r
equires and what is not so important but some are
doing anyway. I feel that the subject of safety can never be discussed enough.
I would like everyone that has an opinion on safety wire and what must be safety
wired to weigh in on this subject. I plan to save some if not all of your
answers for future reference. Maybe we can make a list of what must be safety
wired.
Thanks
Keith
