IMHO they should have mandated lead-free decades ago with a 5 year notice so people could upgrade engines and such. What has happened instead is a long road trying to find a replacement for leaded fuel that can be used in existing aircraft engines without modification. That approach leads to corruption, as those developing solutions to the problem want to patent a new fuel, have it mandated and get a nice monopoly of GA fuel. That is not good for the industry at all.
On paper I was a fan of isobutanol but that didn't pan out either.
- rkangel 5y agoI think drop-in replacement fuel is the most realistic approach. The lifespan of aircraft and of some aircraft engines mean that your suggestion would require a large number of engine replacements and make it prohibitively expensive for the whole of GA. This approach clearly can work, and is only not working because of an incompetent administrator.
- andrepd 5y agoYes, it would be crazy if rich hobbyists had to stop poisoning kids near airports and either give up their hobby or pay engine replacements.
