If you can, why not, it's not costly at all. after fixing(taping) mine, i can't see why the pneumatic/vacuum servos aren't used everywhere, no way they aren't more reliable than the electrical servos. My next upgrade is most likely the trutrac

LOL! That makes way too much sense!

I don’t know. Somebody should ask Mooney.

IMHO, the issue is if G100UL was misrepresented in its advertising. Was there a false statement of fact? Claimed to be a "Drop in replacement". Is it? Was being a 'drop in replacement' a major reason people chose to buy the STC? By relying on that did buyers suffer damage/losses? While damage to your aircraft from using G100UL is certainly a loss, so is the cost for an STC that you cannot use because the product will not meet claims advertised. I see no reason you have to actually buy and use the misrepresented fuel to have a financial loss from the misrepresentation. Paying for a 'license' (the STC) to use a misrepresented product is still a loss due to relying upon a false statement of fact.

Did you get your PC system running? I have the same PC/B11 setup and it was a mess but I got it working great just recently and it's definitely worth it. The Accutrak seems to work but VOR navigation isn't particularly useful, I'm having it connected to the CDI/GPS that's going in soon. The PC allows for very straight flight once trimmed out and it's nice in light turbulence. I installed two aileron servos (previous owner removed them at some point and got rid of them, but it's not a bad job to put them in), and replaced a bunch of the vac lines, there were some unnecessary T's etc from someone fiddling with it before and the gyro wasn't connected to the vacuum source properly. Following the maintenance manual carefully gives you all the info you need. I'm not a fan of the disconnect button on the yoke though, the controls are way too stiff to leave it on in the pattern and annoying to hold the button while trying to make radio calls. Hopefully I can figure out a good panel mounted switch like I've seen Brittain put in some planes. If anyone has a part number or advice there I'm all ears.

Yeah, I was that cancellation. Life got in the way. Paul is amazing to work with.

Hmm, Kevlar was invented in 1965...57 year old M20C, ya think Mooney was that early an adopter?

You're probably right - it looks pretty much like this. Tacking this stuff with a stitch gun over the old materials in the foot wells shouldn't be too hard... https://www.soundassured.com/products/fire-retardant-acoustic-fabric?variant=45293361397918&utm_campaign=gs-2021-06-21&utm_source=google&utm_medium=smart_campaign&gad_source=1&gad_campaignid=17518101047&gbraid=0AAAAADiZDVTaGw9_7gsEXMZ1EZygrZXWp&gclid=CjwKCAjwk7DFBhBAEiwAeYbJsTqyqokx5iicq23eDzEJTUH9uOOXqF1tZRB2MhmUO94pbxlgORVZFxoCDMUQAvD_BwE

That would be me. Thanks for the info!

It doesn’t look like asbestos to me. It looks more like Kevlar. The stuff behind is fiberglass.

I'm thinking of the ensuing pandemonium in the Vintage Mooney community that a positive result would bring, plus the airworthiness directive whose cost will total our planes I'll hold off for now unless someone has real info that asbestos might have been used

I can believe that. I won't be surprised if the hydraulic fluid in my brake and flap systems are all gummed up as well.

Just to clarify, its to a plane power upgrade kit, SAL12-70

Hi, I'm looking at upgrading my charging system since the old one is not working safely. The old one is a delco generator with an Electrodelta regulator. The charge circuit has a 50 amp breaker. In the install instructions it says it only needs to be upgraded IF you want to take advantage of the higher current available. I would be fine to keep it at 50 (safer for old wires as well), but how does that work? Can the alternator or regulator be tuned lower??

Thinking of using this black nomex fabric to cover over the ugly disintegrating areas - thoughts?? https://www.pegasusautoracing.com/productdetails.asp?RecID=3136 Maybe use a simple stitch gun to tack it in place over the old material?? https://www.amazon.com/MicroStitch-Tagging-Gun-Kit-Fasteners/dp/B001CE8JPQ?th=1

It does indeed look like a very sturdy golden/amber fabric encasing fiberglass - just not sturdy enough, as it has come apart at the bottom of the foot wells behind the rudder pedals, and in a few spots above. It seems like one should just fasten some more fabric over it in the areas that have just opened up. I don't see any way to replace it fully without entirely dismantling the avionics, most all else behind the panel, and the panel itself. Even then cleaning it out will be a messy job. I might even tackle the patch job myself if someone can tell me what fabric to use. I want to avoid doing a sketch job with dissimilar materials so as not to inspire regulatory scrutiny (or premature demise in a fire).

If have some material you can buy a test kit at Home Depot and send it to a lab to find out (IF you want to know) https://www.homedepot.com/p/PRO-LAB-Asbestos-Test-Kit-AS108/202731785

Prop blades erode, sometimes you have to dress out nicks and if you have de-ice boots so do they. Mine did not change much but it did change.

I was afraid to bring up the same question....but does anyone know? It is spontaneously fragmenting through gaps in the fabric that encases it. I may already be screwed after my recent unprotected clean up of bits of it lying around in the foot wells. It's a very nicely updated plane otherwise - I'll leave it in my will to a Mooniac TBD who has appropriate hazmat skills.

Not denying your statement, but do you or anyone know how many failures and how many deaths?

I couldn’t agree with you more on that. I fly regularly into both Class C and Class D and more often than not the only reason it is a Class C is that a regional carrier flies out of there. I flew out of a Class D that had busy flight school activities and it was far more demanding than any Class C that I have experienced.

Maybe call a very good interior shop and ask how they do it OR better yet - Do They? I'll bet the original was fiberglass covered in some kind of fabric. I think it is only for heat protection during normal flight (passenger comfort) as the steel firewall meets the time requirement for flame proofing in case of an engine fire. Boeing uses a foil covered "fiber" inside their fuselages that I'd bet would work but would it be certifiable? Some IAs might baulk at using anything not certifiable

Camloc prices have gone through the roof. A couple of things to note. First, stainless is softer than carbon steel and will deform more easily if the studs are too short. Second, if you look closely at the picture posted above, the pins appear bent slightly and the holes are elongated indicating that they were too tight. I had the same thing happen after painting and all of mine that had the pins come out were too tight.

One would still have to have a PMA to sell the part to others. Even if such a part could be STC'd to use. PMA compliance and insurance for the product is not a cheap endeavor It "might" be possible as @MikeOH says but I think its a long shot on such a critical part. Many have died because of the failure of this clamp This is a single point of failure with tragic results if it does fail. It is nothing to trifle with.

If that is the case it shows what a joke the legal system has become. Sorry they made a huge claim, somehow got the FAA to sign off on their BS, now it turns out their BS is BS and they just get to take their toys and go home without making right? If I was on that jury I wouldn’t be voting that way. Think in 2025 folks are getting sick of corp/gov scams, people don’t think nullification be like it be, but it do
