Agreed. ASTM standards, among others, provide worldwide input to industrial efforts toward materials that suit all, not just the minuscule targets we are attempting to placate. For all the inventive efforts of GAMI through the work of Mr. Braly and team, the real culprit in this is the STC process itself and the pressure it put on the FAA to approve an alteration devoid of any consensus standards. Pressure they did not want and had no business trying to approve in the absence of a consensus to which it could point should the recipe go sideways.
And by the way, Russ, those who casually explain that it’s too complicated for you to comprehend are of the same mentality as the researchers who brought us thalidomide in the 50s and 60s. Yes, chemistry is complicated, but it means nothing to the guy pumping 10 gallons of gas into a tank so he can fly to breakfast with the boys.
