They repaired a corroded wing spar cap on my J model, replacing the aft stub wing spar. It was not cheap (20k - 30k), and it took over a year, but the airplane flies great now.

The corrosion looks bad (intergranular with exfoliation) and not "repairable", the second picture does look like a part that can be replaced. I'm sure I know exactly which is the corroded part in number 1, but doesn't look structural to me (like as the spar or spar cap), do you have more pictures?

Nice to see Swift fuel going international already. https://www.travelandtourworld.com/news/article/antwerp-airport-leads-the-bold-charge-toward-eco-friendly-aviation-with-historic-debut-of-swift-100r-unleaded-fuel-marking-a-transformative-step-for-sustainable-flight-new-updates-you-need-to-know/

But a new standard would need to be defined, right? the TCDS calls for 100LL, which in turn have a minimum TEL content. So you cannot have UL meet the 100LL standard.

A very important edge that Swift has in this race is that they are already selling 94UL in many airports, their plan is to phase out 94UL and replace it with 100R. If they manage to get 100R STC´d or somehow approved fleet wide, then they will have a much easier go to market road than GAMI, who is trying to play the role of "shut up, we know what we are doing, you don´t get to ask questions about G100UL, and we are not running our fuel through ASTM or anything similar, because they know nothing about fuels."

I didn't know, I always read about how going from vacuum to electric would mean changing the speed brakes cartridge. This is cool, I guess the cost is much more cheaper than changing the whole system for an electric one.

I'm curious why there isn't a retrofit using a linear actuator, something like: https://www.firgelliauto.com/products/heavy-duty (I'm sure there are better brands, this is just an example). This would remove the dependency on a part that is not longer available, and would also remove the the need for a vacuum system. I'm sure there is a reason why this is not possible, but I don't know what that reason would be.

Meanwhile, Scott Perdue continues lobbying for GAMI. He published a video saying that mluvara oring test is incorrect. In the same video Braly demonstrated that hot 100LL with toluene added on top destroys orings, which is evidence that 100LL (and not the hot temperatures or added toluene) is the problem.

I thought that increase the RPMs would help using the prop to slow down. I know that higher RPM >> more power at same MP. But also higher prop RPM means more aerodynamic breaking, right? What I'm missing here?

I hope the OP doesn't take this bad, I'm not trying to offend anyone. I'm amazed by how "vulnerable" people is to deep fake news, even a very low quality one, like this one, tricks people into thinking that it could be real. Just a few things that stand out on this one: The voice, veeery AI style. At https://youtu.be/lHIpvC1qEXU?t=68 you can see no strut on the right landing gear. https://youtu.be/lHIpvC1qEXU?t=196 the nose landing here is on the tail, lol https://youtu.be/lHIpvC1qEXU?t=270 well, when I started the post I hadn't watched this far, but hey, no one who ever learned anything about airplanes can take this as a real airplane cockpit. So many other details. We need to be more vigilant with the information we receive, from the internet as well as from traditional news papers. Use the best judgment, verify, and look for red flags.

This is a no-no for me. Never ever leave something halfway done. Period. Hand-tightening things that are supposed to be torqued, whether it is an oil filter, nut, or whatever, and leaving it like this, is asking for disaster.

I guess it warrants a poll!

I was thinking the same when I saw that picture

I think this is good news: https://www.avweb.com/aviation-news/faa-updates-airport-grant-assurance-requirements/
