There are not a lot of them. USTs were taken out of service a long time ago. Many dug up, others filled with sand. Many requirements were added. That is why you above ground tanks at most airports.

And they need to realize that their 401K or other retirement is invested in those same companies, so they WANT them to make lots of money.

Yes, I understand you situation, and hope that there is a reasonable fix. Yes, the Monroy "aux" tanks connect to the main tanks through a couple of fittings and and elbow. But I don't think that there is a piece of hose there. But it should be pretty easy to check that. Also, I don't recall, where was your leak? Outboard of the main? Nearly to the outboard end? Also, there is the possibility that when your aux tanks were installed, the sealer was not properly applied. Out of date, or mixed improperly, or beyond the pot life. That. IMO, is the big issue. There are SO many variables.

I guess you did not READ the posts about the fuel being introduced. RHV has an old underground tank that was not being used. They resurrected that for the G100UL

I used to have a JPI 830 and the stock setup in my 252. There was about a 30 degree difference, with stock setup reading lower. Then it got to be a bigger spread. Shop changed the stock TIT probe, and the two were reading about 10 degree different.

Right this minute, I would put an MT on. Hartzell is supposed to have a composite 3 blade coming, but it has been "almost ready to start selling" for several years.

The biggest downside to the staged upgrade, IMO, is that it costs more. It does help if you have a plan and communicate with the shop, so they can install wiring for your final panel the first time, and avoid pulling and reinstalling the interior several times. Definitely tell them you want to add the Yaw Damper later, as they can run the wires and then just have to install the servo and configure. But it also makes it harder on them to remove the old wiring, as they will have to keep some or remove it all, wire up what you have, but then have to pull and rewire when you do later stages. As an alternative path, I would consider 2x G-5, GFC-500 and GTN-x50 as the first stage. And do your instrument rating on that panel. This way you learn the GTN well as part of your training. And gives you experience with tape readouts for speed/altitude/VS making it easier to transition to the G3X. And having both, the GTN-750 is SO much nicer to use than the 650, think about that also. Long term, EIS is very important, but you can live without it now. Or you can add a lot to a JPI 700 just be adding sensors.

T-37, T-38, A-10 Gear then flaps. Actually Speed Brakes, then Gear, then Flaps. And it was always full flaps, not intermediate settings for approach and landing. Partial flaps was for take offs.

I cannot vote, as I cannot answer several of the questions. There is no option for Do Not Know or Not Applicable. You also did not have options for people who resealed before they had leaks. I don't know of any patching on my plane, so NA. I don't know if the reseal was due to leaks, or just figured it was time. The original went 23 years.

Can you make the adjustable brake links for a reasonable price?

I have mine out of my 252. I have: HTS-CF Part number 01-0770329-01/A490A A490PTS-DF-14 to 28 - Part Number 01-0770329 - 06 ( I think it is 06) A490ATSCF Part number 01-0770062-03 Rev U All are rated for 14 and 28 volts. DM me.

I can't see not flying a turbo up high. I have a Mountain High O2D2, and with that, the tank gets filled during annual, and that is it. And I now have an oxygen concentrator, so when 14K or below, it will supply 2 people. And above 14K, I am on ship's O2, and my pax on the concentrator.

That is encouraging. I did not do the factory tour due to mobility issues.

You are assuming that everyone that patched a tank: 1) Used the same product as original 2) Used it properly (expiration date, mixing, pot life) 3) Properly prepped the surface. As shown in pics by @jetdriven, MANY patches he has seen do not meet those conditions. Too many people doing crappy work over the 30 to 60 years since the airplane was made.

A bit late. Happy New Year

Who is the second Mooney?

Right now, they are using ethanol to boost octane on lower quality alkylate. So not that easy for them to do that.

There used to be 4 grades. 80/87 - Red 91/96 - Brown. This was the first one to go away, driving people to 100. My AEIO-360-B2F (180 HP)is rated for 91/96 100/130 - Green, replaced by Blue 100LL. 115/145 - Purple. Used by airlines and military. Still made once a year for the National Air Races ADI is a pretty major mod to keep flying. And adds more maintenace and having the availability of the fluid everywhere. And remember, while only a small part of the fleet requires 100, they burn the vast majority of the AVGAS.

Except that MOGAS is highly variable. Especially when you get outside the US. In the old days, you could blow up your car running Mexican auto fuel.

True. But so far only one Mooney has been reported with new leaks. So makes me suspect the sealing history.

Mooney supplies parts that they make. I have ordered parts and gotten them. They are NOT supplying parts that they contract from other manufacturers. And Johnny addressed a group buy with pre-payment. Mooney will not do that as they need to be sure that the doors are open when the parts show up to do the required QA and then shipping them out. They do have some stock of some outside parts. I was able to source the knob to turn the O2 on/off.

I bought a stick on clip from Amazon. I stuck it to the side panel above my knee. https://www.amazon.com/gp/product/B081PKGJS5/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

To expand a bit, single stage paints are color and carrier all in one. The "protective coating" is the paint. In the days of lacquer, you needed to buff the paint to get a shine. Enamels dried slower so would level and be shiny without extra work. Clear coat paint systems have the color sprayed on and allowed to dry/cure, then a clear paint is sprayed on top to give the shine and protects the color coat. In the auto world, many systems use water based color coat to reduce VOC emissions.
