ASRS this ASAP. You both screwed up, but the controller led you into it.

My answer is not listed: I still plan to try G100UL. But I'd like to learn more first. Look, my paint isn't awful, but it isn't great either. I presently have a small seep at two rivets and one access panel, within limits. Will probably correct at next annual. If I had a problem I'd finish the tank of fuel, sand/scuff, prime, and rattle can that thing and not lose sleep over it. So much other touch up has been done with a rattle can and came out fine. BUT, what I don't want is a situation where G1000UL compromises the tank sealant. A much bigger job.

The now-gone thread was picked up by Avweb which posted a link generating a wider audience. I appreciate the reports from the Mooney community, George's response, and the dialog to figure this out so we can use this product knowing all there is to know...

My sealant is still original 1966 and has held up remarkably well. Every few years I'll get a seep and patch it, and that's worked okay. Does the age of the sealant have anything to do with G100UL? I'm not well versed on what changes have been made to sealant since then.

I'm right there with you, coming from the flying an airliner thing for a paycheck. My Mooney is similarly equipped and looked like a King showroom piece in the early 90s. BUT, 3 things I come back to for my Mooney, should I upgrade it: 1) Vacuum instruments need to go 2) An RNAV/LPV approach is now the best approach (and often the only approach) to many GA airports 3) The ancient 6-pack of engine gauges and their associated plumbing on the wrong side of the firewall are ready to go

Larry - thank you, and I'm sorry that's happened. I think that's going to sideline me from G100UL. I've got a couple of very small seeps. Within Mooney service manual limits for airworthiness, but it would appear this will invite some paint stripping. My paint isn't the best, but it is sticking to the airplane with those seeps.

This question...... really depends on conditions. Will my E model climb out of Leadville, CO on a hot day with full flaps at high weight? Probably not. Will my E climb out at sea level, cool day, solo weight, half gas? Sure. Other models: Density altitude, weight, engine type, and so on....

Keep us posted! I'm very curious from those of you who use G100UL, and have small seeps, what the outcome is. Currently I have not yet put any G100UL in (but was planning to). I have a couple of minor weeps that are airworthy, i.e. a couple of rivets with a small amount of staining and a tank panel with a small seep. Could fueling with G100UL make those worse?

Multiple electrical issues would really concern me. It doesn't sound like a coincidence. Does your airplane have a volt meter? Can you see what your alternator/generator is putting out, without risking damage to other equipment?

My logbook shows 1697 Mooney landings. I estimate conservatively that half were tough and go, if not more. So 850, and counting, without incident. Including 2 the day before yesterday.

Here is what WVI sent to us https://files.constantcontact.com/8de5a020301/ed54fe6d-3e1e-4002-b1f6-e71e9170cf20.pdf?rdr=true I think the idea is to get buy-in from those based at fields where G100UL is launching. And a "please ask your manager to carry our fuel" note for the neighboring fields.

G100UL free STC offer extended to neighboring KWVI this week, my home field. I am going after it and looking forward to trying it out and seeing how things go. Not too enthused about more expensive gas, but I have been less than enthused about lead contact for a while now.

I put a fine wire spark plug in the bottom of my cylinder that was oil fouling a bit (and easily cleared with 2-5 seconds of runup at higher power than normal). 600+ hrs later..... AOK!

OP please ignore this if it is obvious to you but I feel it should be mentioned: The traditional style strobe lights like in your photos typically have a power supply that takes aircraft DC voltage, charges some sort of capacitor, and then creates the flash with a rapid discharge. So any strobe replacement with LEDs is not merely a remove and replace, you'll need to remove that power supply unit as well (mine were mounted to wing inspection panels) and run DC power straight to the new lighting. A weight savings!

3-5 days. For the repair, can’t speak to an overhaul time. Can’t complain about that! We’ll see how it goes, system is still en route to them.
