See previous thread on this subject. It's been proposed for a long time and just hit the fan, as it were. Yes, I'm affected. https://vansairforce.net/community/showthread.php?t=189895

Yup I have one too

Hopefully Superior will help with the cost of the replacement crank at least. I realize that ADs are not mandatory for experimental engines; however, I value my butt too much to ignore this one.
