Inspection recommendation

[chrisl108]

I'm working on a 320, and found what looks to be a crack in crankshaft near the flange. Hopefully, the picture shows it. From what I read it seems a mag particle inspection is the way to go? I found that in older Lycoming service bulletin, when the flange lightening hole problem was going around..

Appreciate any thoughts, this forum knows a lot more than I do!
