FAA approves unleaded fuel for piston fleet

This is great! Expect the EPA and the FAA to finally ban 100LL, which will be a great boon for everyone. Note, you will require an STC, but not poising yourself with lead will probably net out the costs in the long run.

* I am a pilot of piston engines, and I really don't like 100LL being the only option

ul94 has been around for a year or so (I've had the stc since last december), but yeah for high compression engines, it was 100LL or nothing. I'm hoping the stc is comparably priced, $100 or so.

this is really awesome.

edit to add: for the non av geeks, an stc is a supplemental type certificate. it's basically an faa stamp that says, "this aircraft has been changed from when it was initially certified, but it's an approved change"

George Braly in the video interview indicated it would be similarly priced to the Petersen STC, which used to be $1/rated HP and now appears to be $2/rated HP.

In short: it’s no barrier whatsoever to adoption.

so a little more expensive than the swift stc but yeah still totally worth it.
