This is very true, but it’s also likely the first place they visit when looking for help with an obscure Mooney issue or part. That is how I found mooneyspace…

@George Braly I for one appreciate your participation in this forum and willingness to enter the debate. the challenge as an airplane owner is the repercussions for having “old paint” and “old sealant”, are not trivial The consequences for the experiment have a significant downside. I am actually planning a paint job and Craig with scheme designers has told me that he is going to start a thread with you and Sherwin Williams regarding this issue. the last thing I want to see is a sealant and paint failure after a major investment in painting an aircraft. I have no idea what is involved with dealing with FAA approval for something as significant as a new fuel but it cannot be easy, pleasant, or cheap and I commend your efforts. I just don’t want to be a guinea pig to see how it works out. I’m thankful that there a plenty of others willing to roll the dice.

I served on a local county board which helped evaluate changes related to our industry and make recommendations to our country commissioners. one of the issues was staff wanted to require use of a a new type of back flow preventer called an RPZ instead of the double backflow. The latter being what has always been used, and they wanted to require a new one that they claimed was safer. During one of the meetings when I was questioning the requirement, I pointed out the problems with the new type which in some instances would require a building owner to spend upwards of a million dollars to upgrade. i had researched this issue extensively prior to the public meeting so I knew the answer to my question prior to asking. When I started pointing out all of the pitfalls of the new requirement, one of the staff suggested that if a baby died because of contaminated water, it would be on my head. Which was the perfect opening for my question which was… How many documented failures of the old back flow preventer had occurred, and as a result how many of those caused illness or death? As his face turned purple he claimed he didn’t know the answer, to which I replied well I do! The answer was zero! It had never happened. The bureaucrats had made the rule already and imposed it on more than a few residents and it had to be rescinded. The moral to the story is that while there is no argument that lead is bad for us to ingest or be exposed to, the actual danger is poses as a byproduct of fuel consumption is more difficult to quantify. It isn’t as if aviation exhaust is being pumped into schools. But the “save the children argument” is foisted and everyone’s hair is on fire. That being said, high pressure direct injection, and electronic ignition on engines would render this point moot, so if the FAA and EPA were actually interested in efficacy and an actual solution, they would get the f*$& out of the way and let some real progress In engine technology occur, rather than stifling innovation. I am of the opinion that the indirect mission of the FAA is to purge GA from existence, so endlessly harping on lead is much easier than admitting they want the whole mode of travel to go away. It’s a war of attrition with your own money being confiscated and used against you. government at its finest

Well, damage to fuel tank sealant is a show stopper. im not putting a drop of that in my tanks until its ready.

That is a clever design, but I would never pull the cowling without three strips of painters tape on the body directly behind the cowling. look at 4/5 (long bodies at least), and you will see why.

Even an annual can be misleading. The plane I recently purchased had what I would classify as incompetent maintenance. They didn’t do any SB’s, a lot of things done improperly, and a lot of things well out of spec. Original landing pucks from 2006, original brake fluid, original mags one of which has never been overhauled, the list is not short. Same 3 or 4 shops did all his annuals, none of them mooney’s service centers.

Setting realistic expectations will make all the difference in the world when walking into a big project like that. Had they told me 17 months and I had accepted it prior to beginning, it would have been a lot less stressful. I absolutely believe a project can take 5-6 weeks of actual manpower, and if everything is planned, ordered and or available it could be done in that timeframe. But if a shop told me that with confidence I would still be pretty skeptical. It not usually all their fault, sometimes it’s a quality or elective issue. The market and regulations play a large role in your options as well. Once your plane is in 1,000 pieces of the floor of the hangar, what are you going to do? It’s not worth litigation unless you have enough money, time and will(masochism) to hold to the principle. Having it moved isn’t a real good option, and no one else can really work in someone else’s shop etc etc. Whatever someone, anyone tells you, just multiply that by three to five times and set that as your expectation. This way if it happens on time, you hit the lotto, enjoy it. And when it doesn't, you will be prepared and may even be able to leverage a few freebies as a concession. I’m really not criticizing or busting anyone’s chops. It’s just something that should be baked into the formula because it is not the exception, it’s the rule. This would apply to any major upgrade/repair/alteration, not just avionics. I firmly believe it is going to get a lot worse, and a lot more expensive for a while anyway. There is no generation of people aspiring to work in these trades, much less in the pipeline training. While that may sound cynical, it isn’t really meant to be, just stressing the importance of proper expectations. These are large and discretionary decisions, it can be pleasant if it goes the way you expected….

After watching that YouTube video I can’t believe this didn’t come up in gami’s testing. that experiment is damning. I have zero interest in using g100ul until they resolve this issue.

@sandeepdutta This is probably one of the better deals out there for a k right now. This plane was the first Mooney I ever logged hours. It was owned for a long time by an instructor that I know and was well cared for. he sold it a few years ago and the new owners did some significant upgrades. im not sure why its hasn’t sold yet, I think it could be had in the 165 range and has all the big stuff done. Paint scheme isnt thrilling, but it’s clean, well kept, low time engine, intercooler, Merlyn waste gate and a gfc500 https://www.trade-a-plane.com/search?category_level1=Single+Engine+Piston&make=MOONEY&model=M20K+231&listing_id=2428328&s-type=aircraft

I don’t disagree with this. Ironically, they never even asked me what the part they were making was for. That being said, most people not involved in aviation are unaware of the challenges and limitations.

Years ago I bought this really high end Italian oscillating belt sander. It worked really well for a few years and then the oscillating part stopped working. I took the machine apart and found this helical worm gear made of bronze. I hunted for the company only to find out they had gone out of business years ago and if I couldn’t get the gear the machine was scrap. Well, a new machine of this size and quality was over 20k so I started looking… I ended up finding a shop in Columbia (the country) that would to produce the part for $75. I ordered three of them and zip tied them into the machine near the gears… I’ve used one more set of them and apparently this was a part designed to wear to spare the more expensive parts. sorry for the tangent but my ocd required me to complete the story… point being, I’m not going to retire any machine I own for some part that I know I can figure out a way to replace. I understand there are some things on the plane like a turbo housing, or a crank that are far too complex and critical to produce yourself, but the FAA treats too many things as critical, that just are not so on our little planes. Good machinists all pride themselves on being able to do complicated things, and they are extremely knowledgeable about metal and its properties, those gears are not that hard to manufacture, and I’m willing to bet if you knocked on enough machine shop doors you would find somebody willing to make them.

I read an interesting little anecdote in a shop the other day… ”every 20 minute job is one broken nut away from a three day nightmare”.

It doesn’t take much, looks like all boost was gone with 28-30” being atmospheric pressure at sea level. I had a loose hose clamp and split boot and that’s all it took to lose boost in mine. I fixed the hose clamp and had full on the ground, but when I went up above 7 I couldn’t hold full MP. it takes less than you think.

It could be an induction leak, it’s harder to find at the higher pressures, but check all of your clamps and hoses. I have no idea what the setup is on a 210, but I have had to chase these before on my io-540-s1a5 and it can be a little from multiple locations or a lot from one or all the above. Start with the easy obvious places first, hose clamps. how do you check the relief valve?
