The bottom line is not that the noncertified engines get a free pass,
or they shouldn't, but that: 1. Certification of the engine, is not required of aircraft with Experimental/Amateur-Built C of A: 2.Is of no benefit except you get a shorter fly off period: 3.The commonly available choices of certificated engine unless you can buy a new PT6A-34 are simply ridiculous from any reasonable standpoint. I believe if you want a certified engine perhaps you ought to have a certified airframe to go with it. If type certification improves powerplants, doesn't it improve airframes as well? To think otherwise is schizoid, particularly in a world where you can buy easily rebuildable certificated aircraft and an overhauled museum piece and prop to match for less than a lot of people are putting into kit planes. And as far as the electronic issues go, I don't want FADEC on any engine, certified or not. I would rather have mechanical FI or a float bowl carb and a one mag one electric system (like Franklin so intelligently used as did Shaky Jakes). Actually the most reliable engine control system in the world is PT Cummins Diesel injection but that's another story entirely. All hydromechanical. |
