Would an engine built out of certified parts, but without a name tag be considered a home made engine?
That's what my engine will be. I started with an 0-200 crank and a spare case, milled and bored the case to accept a fuel pump, found a C-90 cam which has the lobe to drive the fuel pump (has the same lift & duration as an 0-200). Most other parts in it are from everything from C-85 to 0-300 (gears, rods, oil sump etc) The case I have has no name tag on it & I intend to leave it that way. I'll stamp something into the case where the tag should be that identifies it as a "JS-90-F" or something to that nature. It's for certain that this engine could never be used in a certified plane. Best that ever could be done with it would be to tear it down and use some of the parts, and they would have to be inspected and certified by the overhauling shop. Hence complying with any AD's before becoming "certified parts" I'll probably do the same with all the accessories as well. That way... no AD's should be applicable. Of course, complying with something that would be serious or life threating would be something I'd want to do anyway, but I'd want to make that decision.
