I let my DAR know, or ask someone at your FSDO. They will tell you, but I do believe that an engine change will do that. In fact, if I remember correctly, I went back to phase 1 when I changed from the VW to the Corvair on the BlackBird.

So let me pose a question. If that is true and you make a major change like going from a VW to a Corvair do you have to go back to Phase 1?
