I am building the engine for my 9A and the crank would not pass SB-505.
I know it really doesn't have to for an experimental, but I would sleep better knowing it doesn't have pits on the inside of it.
Mike at Rick Roman's said mine would be fine for an experimental and it only had a few pits left after grinding the bore out to the max, he just couldn't certify it.
Do any of you now fly with a crank that isn't certified, IE: won't pass the service bulletin?
Do you trust it?
