Awesome documentation. I hope to do 1/2 of what you did.Since this thread stopped being a sticky, I'll add my L3 doc to bump it back. I've found this thread to be incredibly helpful and would love to see it regain "sticky" status.
Everything on my L3 project is pretty much wrapped up other than the cert flight itself. Hoping to fly it at MWP in late October. My TAP, Chris Pearson and Steve Eves, were incredible helps on this one.
