I certainly agree with George.
Being in the air is not place to have ..." I wish I had
..." thoughts. My view is if there is any question or doubt as to its
condition then I replace it. Yes, I know used parts in many cases are more
reliable than new as they are past the infant mortality period. I do reuse
parts. The e shaft in my 91 block was also in 1986 block - still looks
good as new so I naturally reused it.
I tried used rotors and in my case because I did not know
to check the critical apex seal slot wear ended up swallowing one and aborting a
trip to Sun & Fun. You need to know what is critical about a part and
then check that parameter as being comfortably within
specifications.
Also, what I might not even have a question about putting
in a car - will get rejected for airborne duty - 4F.

Subject: [FlyRotary] Worn rotor
housings
My .02 Joe,
My first teardown and rebuild
13b had rotor housings with some of the steel plating missing along one edge.
I took them around to every "expert" that I could find, they all agreed that
they were fine to use. I then went ahead and assembled the motor, with
new seals, gaskets etc. The motor ran great, like brand new I
imagine.
But, When it was time to install the motor into my airplane, I
just didn't feel good about those rotor housings, so I found another motor
that I've been flying since 1998. By peeking inside I knew that these
housings were pristine. I still have the first motor, but I doubt that I will
ever use it without another rebuild with new housings.
Bert Rutan said
something to the effect of "Do your very best, even that will only be just
barely good enough".
I know, that sitting on the end of the runway, I
must feel confident that everything is as good as I can get it, in order to
enjoy my flight. Others will differ perhaps.
