My point is, making the process easier, cheaper and more accessible to people. How many people would buy and start kit planes if they had to hire an IA to sign off on each stage of the work and keep logs about everything, buy only FAA certified parts, keep all the paperwork straight and no modifications not approved by the FAA allowed? I believe that if the project appealed to the hobbyist as more doable and less red tape, more people would go for it.
You personally could buy that neglected Mooney and put an IO-470 in it and enjoy the fruits of your labor.
Well, when the Experimental/Non Commercial rules come into play, we'll have the opportunity to see how that pans out. Right now you could look to Canada to see what you can see since they already have that ability.
