Hi Keith,

First, anything required to be safety wired in the airplane construction can
be found in the Maintenance standards.  So I presume you are referring more
to the rotary engine installation.

So, here is what I have safety wired regarding the engine installation.

1.  Oil pan drain plug
2.  Oil filter

That's it. Over 500 hours engine run time and nothing has come loose - yet
{:>).

The engine mounting bolts do have cotter keys, so perhaps that counts a
well.  Also,  I do use all metal lock nuts whenever I use a nut on a bolt
inside the engine compartment.  My prop bolts have their heads in a slot in
the crush plate and the other end through the prop flange and - yes, large
metal lock nuts.

But, that's about all I can think of in the engine compartment.

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 requires 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
