I know in the experimental world we don't always use certified parts. I have my crankshaft at the machine shop and it failed for the flange thickness being to thin by 0.005. The machine shop believes it came from Lycoming that way since they were the last to overhaul the engine and that Lycoming has different limits than field shops. If that was the only thing wrong with the crankshaft and everything else passes, can I decide to use it without a yellow tag? What are the regs on this? I plan to use it for my own a/c. Curious what others have done.
Thanks,
Jay
