FAA Expands Approval List For Swift Fuels' 100R Unleaded Avgas

The FAA expanded approval for Swift Fuels' 100R unleaded avgas, adding more than 1,200 engine models and 1,600 airframes to its STC.

From the press release:



This is a problem. At the moment, the FAA has two approved UL fuels that cannot be intermixed. This will make XC travel extremely difficult if not impossible in some cases. Flying from a region that sells G100UL to a region that sells 100R, or vice versa, will require draining out unused fuel before refueling with the new stuff. More likely, the conflict will go unnoticed, and a line crew will simply top the tanks with whichever AvGas they have.

G100UL is at how many airports?

This is a red herring argument.

About as many as 100R.

As is the comment about lack of ASTM standard for G100UL. The press release that Swift let out at OSH sounds warm and fuzzy...1,200 aircraft engine models approved for their fuel. Of significant note is the lack of any turbocharged engines on that list. I won't rejoice unless that list is markedly expanded. Patiently waiting with interest.....

 

[Jim K]

Yeah, this is more nothing. 1200 sounds like a lot until you realize they're mostly variations of some obscure aircraft you've never heard of. Let me know when there's a Cirrus or A36 or 300hp PA-32 on the list.

And the aml for swift appears to exclude engines that actually need 100 octane

 

[Darryl Snover]

Interesting that the list of approved models includes the Mooney carbureted versions (M20C, G, D, B), and oddly ONE of the IO-360 versions - M20J. That seems odd, in that the M20J is, as far as I know, still the IO-360 A1A that I have in my F model (although I think there's some that have other 200hp variations).

This may just be what they're confident in approving at the current level of testing. I'm actually curious how they're doing testing, that's an awfully long list of engine variants and air frames so I have to imagine they're using representative examples of different groups rather than going through every possible combination.

Key words there are "from the press release" - Swift has absolutely zero incentive to intermix with G100UL and a lot of incentive not to. They also get to cast shade with their comments about both solvents and ASTM. I can guarantee they've done no testing at all with G100UL, just written stuff.

I really, really despise how Swift has handled this. GAMI hasn't covered themselves in glory either, but Swift's whole marketing program is based dumping on G100UL.

I agree with you, but I wish the FAA would require proof that a new fuel can be mixed with all previously approved fuels before issuing a new STC.

 

[Ed Haywood]

Can it be used in this?

 

[Tom J]

Still waiting for them to add the 200 HP Arrows, II, III, IV, to the AML.

 

[tspear]

About as many as 100R.

GAMI shows four: https://g100ul.com/map

Swift shows a lot more for the 94UL: https://www.google.com/maps/d/u/0/viewer?mid=1fNC9vcS4U3u15y5FxBZ_d6Mjqvw&ll=40.805955463244246,-94.37862123125001&z=5
I have seen a few press release where Swift has announced 100R in use at some locations, mostly for testing. I have not seen any public available for use announcements.

The PR from Swift states as they expand the 100R STC, all STCs for the 94UL automatically include 100R. Therefore they will rollout 100R at all locations currently using 94UL.

It will be interesting to see if this matches reality. If Swift is able to stay on pace, they could become the defacto solution for a while. How long, would be an open question if Lydonell (sp?) manages to pass EAGLE.

If you read through the FAQs on Swift's website. the approach with the FAA seems to be more about testing engine models, and general plane classes. So as long as the intersection of those two meet, it gets added to the list.

More and more I'm seriously considering selling the cherokee. Of course it's 95 in Denver right now, which adds to the decision. Too many of my local (and OSH) flying friends have sold or no longer fly for various reasons, and it's just not that much fun these days.

Swift is just re-gifting the 94UL list to gaslight "progression", chat. It's wild that has to be premasticated for some of you. ETBE can't make power spec for all installations in present circumstances, time to come to grips with it. And that was a very mealymouthed dipping of the toes at 8.5 CR NA and a baseline of 22* before downtiming. Translation: Angle valve Lycos are cooked (8.7+ and already down at 20* to not detonate ...on 100LL.).

Back to the topic at hand: Swift's 100R is the only impostor here among the 3 so-called competitors. All they have is rebranded 94UL. This announcement all but spells it out, if people could stop foaming at the mouth about ETBE not making 100LL parity for one second.

 

[AlphaPilotFlyer]

is there any info for planes with mogas stc and mixing it with any of the new stuff?

 

[455 Bravo Uniform]

I don’t understand how the fuels are not mixable, unless one fuel has lower Octane Number than the other. In that case, aircraft approved for the lesser Octane Number fuel should be good to go.

I’m probably in the screwed boat with my IO-470-F. I’ll probably just mix my own and fly outlaw.

So....

Swift is fungible with 100 LL
GAMI is fungible with 100 LL
But Swift and GAMI aren't fungible? ???????????

AND......
Wake me up when Swift works with turbo's, high compression, and other engines that need real 100 octane. Until then, if it were up to me I wouldn't allow it to be sold.

See the link above. Swift has just entered into an MOU to expand the testing into that regimine.
I actually prefer the approach of Swift and Lnydonell. Both are being slow and methodical. No big bang approach with effectively all models and then find out about all the issues.

I wish them well. Let me know when the fuel is good for any plane that can currently use 100 LL. And costs as much or least that 100LL.

the m20j is an 8.7 compression io-360 engine
