I don't fear a change to the rule. I just don't think you're likely to get any better, practically speaking. Trying to push for a better position than we already have (which is pretty fantastic in the broader historical and geopolitical context) could invite more scrutiny or agitate those who don't want us to have this freedom. Would you please clarify what you want the rule to be? And if it's substantially less than 50%, would it not be inappropriate to call the category Experimental, Amateur-Built? Wouldn't it be more like an uncertified commercial aircraft product, some assembly of which might've been performed by the customer? Couldn't Cirrus offer an SR-22 in this category, bypassing all of the certification requirements simply by having the customer come and screw in the instrument panel and install the seats?
