On September 1st, the Federal Aviation Administration approved the first unleaded fuel found fit to power every spark-ignition engine on every airframe in the general aviation fleet. The process has been long. Here is a link to an earlier approval.
Having the fuel approved is the easier part, the tougher part is getting distribution nationwide. California is the most crucial since “some municipalities have prematurely banned the sale of leaded avgas“. The progress made thus far wasn’t a foregone conclusion, as AvWeb noted as recently as July. In May this year, the EPA announced “evaluate whether emissions from piston-engine aircraft operating on leaded fuel contribute to air pollution that endangers public health and welfare.”
This is big news for the general aviation segment. As commercial aviation moves towards its net zero goals far off in the future, it is great to see that general aviation is also working towards solutions that improve the environmental impact fo flight.
Co-Founder AirInsight. My previous life includes stints at Shell South Africa, CIC Research, and PA Consulting. Got bitten by the aviation bug and ended up an Avgeek. Then the data bug got me, making me a curious Avgeek seeking data-driven logic. Also, I appreciate conversations with smart people from whom I learn so much. Summary: I am very fortunate to work with and converse with great people.
