What's up everyone, just joined the forum the other day, mostly just looking for info on what engines can be put into experimental aircraft, both certified and un-certified and some of the steps that come with possibly having a non-certified engine in the plane. I'm in the process of having a JMB VL3 built and there's a new turbine engine from a French company called Turbotech, that they are offering and have installed in a few of their European sold planes. I'm mostly curious about the hurdles of having that engine in the plane vs the 915IS which is US certified, even though the plane will be a certified Experimental. Hopefully the forum will offer some answers, thanks for the help!
