I just forwarded the section for "Twin Wasps" post to my FSDO for them to look at. It looks like getting the CL thrust restriction removed from your commercial/ATP will do it. So the Flight Instructor certificate should say MEL but only valid when accompanied by Pilot Cert xxxx. Since the Pilot Certificate has the restriction, not the CFI cert. then removing the CL from the Comm/ATP should work. We'll see what they say. This is when I would not want to be an FAA Ops Inspector!
