I do remember the lawsuits. They killed small aircraft production. I wonder how this complainant can prove that the 100LL caused his conditions? Also I would imagine the proportion of lead in the air, even around an airport, is miniscule. Addtioinaly, Cessna has not approved any planes to run on unleaded yet, as far as I know, because they are still in the testing phase. I would be more concerned about the aromatics that go into aviation gas than lead. right about now.
Why did he single out this one operator? 4 guys with a partnership hardly fly as much as a charter op or flight school.
Oh well. Anther frivilous law suit it appears. Trouble is, all the angst and level costs to fight something like this, only to ultimately get a judgment against the complainant.
