@anthonydesmet You may want to verify the status of your V-band clamp before you remove that exhaust pipe. See AD_2023-09-09. If you need a new one, part numbers are 670105 (new) or 653337 (superseded) and they are currently hard or impossible to get.

Before you let them pull the cowl flap motor and send it for rebuild, I would remove the upper and lower cowl, get a helper, and have them run the motor from open to closed several times while you watch the mechanism. It's a simple enough system and it sounds to me like something is dirty, binding, or mis-adjusted. You could also try to pull the mechanism open gently by hand to see if the motor is slipping internally. I have the 252 style cowl flap motor and it was sticking closed in flight. It would eventually open but only after the switch was left in the open position for approximately 60 seconds. Could not duplicate the problem on the ground. A&P replaced the cowl flap motor after I gave him the info for Globe from this thread. When the new one came back, it did not fix the problem. What did fix it was thoroughly cleaning and re-lubricating the arms and cable that open and close the cowl flap. I did this by spraying it out with WD-40 to clean, then Tri-flow to lubricate, while someone else in the plane opened and closed the motor several times. Quite a bit of dirt and gunk came out. The flap now opens and closes smoothly and more quickly than it ever has.

Currently doing the same. AirPower shows them on backorder. Their website says estimated available 1/29/2025. I called and they said they get them from Boeing and actually maybe not until October. RAM Aircraft may have a PMA version that matches your part number. My A&P is trying to source it there at the moment. Situation is not very good.

Lubricating automatic wastegates with Mouse Milk seems to prevent or fix many issues with erratic boost. No experience with your engine but mine gets lubricated at every oil change and annual.

Agreed. Definitely a basis for more testing to see if his results can be duplicated, and a reason for concern.

For those quoting the filing in opposition to the motion to enforce the settlement - You're quoting a lawyer hired to obtain a result (avoid enforcement of the settlement). They've written it very well and did a good job. However, the "facts" you are quoting cite mostly to one or two "declarations" - e.g. "Hoyt Decl. ¶ 17." A declaration is an unsworn statement written out by a witness related to the lawsuit. Sometimes they do have them sworn under oath, which technically makes it an affidavit and not a declaration, but that's not all that important. The point is, you're quoting a statement by someone named "Hoyt" that summarizes the positions of third parties not involved (Lycoming, Continental, Textron, Piper, etc.) that was carefully edited, if not outright written, by their lawyers. It's an out-of-court statement with two or sometimes three layers of hearsay. And now being repeated over the internet. Any lawyer or judge knows those statements are not admissible in court at an actual hearing or trial, and also knows these types of pre-trial filings are often full of inaccurate or false statements that don't bear out. It's a lot of pre-trial posturing. I don't know how much of any of it is true, and neither do any of you. I personally will keep an open mind.

Been a Garmin Pilot user for 10+ years. I don't like Apple products. I had Foreflight on an iPad when I first started flying but made the switch not long after and ditched the iPad. I find GP very powerful and it does most everything a top-of-the-line Garmin panel will do and integrates nicely with those panels. It's not the most user-friendly but gets a little better on that front every year. My father still uses Foreflight on an iPad and iPhone and finds them easier or more intuitive. To each their own.

Another +1 for Maxwell in Longview, TX. I fly about 2.5 hours to take the plane there and commercial home, with a connecting flight through Dallas. Pretty sure I'd still do it if it were 5 hours too. No experience with any other options nearer to you though.

Well, the check valves cleaned up OK. No broken parts and after cleaning they are not leaking. However, the A&P discovered the turbo was loose and wobbling where the two halves bolt together. Video below. I can't figure out how this would have caused the oil leak while parked. Perhaps a dirty check valve and the failing turbo are a coincidence? Regardless, the turbo will be going out for overhaul. https://drive.google.com/file/d/1-VZ3uV-Wz3wp637t6a4yGIRh2e3x64VV/view?usp=sharing

Your new plane might already have a riveted clamp, if it was overhauled 200 hours ago. Unless the logbooks show the clamp part number installed, you'd have to look at the one on the plane to verify. The TSIO-360 K model clamp part number is 670105. Air Power is currently showing it estimated available 1/13/2025 for $830. I have one ordered and fingers crossed it ships, because my turbo is headed out for rebuild.

We have two videos with what appear to be contradicting "facts". Somewhere, there's a scientific explanation for it. I don't think anyone knows what it is yet. In science there is no such thing as a "baseline" fact. Just ideas and theories. Mr. Braly and GAMI have posted their video with their names and their company name behind it and come here to answer questions about it. They've had their testing of G100UL independently verified by the FAA, as far as I can tell. I've seen Mr. Braly from a distance speaking on G100UL at Oshkosh workshops and I'm pretty sure he's a real person involved in this industry for many decades. The other video you reference as fact was posted as an unlisted video under an anonymous internet alias. All of the spoken "facts" in it are a from a faceless, nameless voice off-camera. He hasn't come to Mooneyspace to answer any questions. I don't think we know much of anything for sure based on his video. Is it a reason to ask questions and engage in further testing? Sure. Can we use it as a "baseline" or "fact"? No, not reasonably. Demanding that anyone accept it as fact is also unreasonable. Do we really know that the substance in the video was G100UL, or that the paint was Jet-Glo?

I'd also decided not to post any more because of the negativity and hostility, but here's one more try. If George and GAMI were just out to make money, there are far easier ways than G100UL. It seems to me they've gambled a huge amount of money over many years on a very risky project that just might keep all our old airplanes flying when they otherwise could have been grounded. This website is a great resource, but it bothers me when vendors come here and get viciously attacked by a few vocal members. Some members pretty much ran the EarthX people out of here after they posted about the STC for their new product for the old Mooney fleet. This thread feels the same. We could do better.

Had a '68 C ranger for a while. Great plane. Got my instrument rating in it. Did have trouble for a while with the hydraulic flap system. Kept springing leaks. Eventually got it fixed, it was just O-rings, seals, and shop time. Plane lands and takes off fine without flaps. Did find corrosion in a wing spar cap. Cost 25%+ of the plane's value to fix it. Maybe could have scrapped it but it was a good plane. Glad we did fix it - Someone is still flying it on the east coast. Check carefully for corrosion everywhere you can, just like with all 50+ year old airplanes. Otherwise fly on.

OK then. Mine seals very well installed backwards, and looks like it was meant to go that way to fit into the shape of the fuselage frame. But you should probably install it like the factory did. Thanks for the photos Guy.

The seal is P-shaped. The flat part would definitely not fit under my trim panel, which is trimmed way above the seal surface, though I believe my trim panel has been replaced, so I'm not sure how it came from the factory. The way it's in there fits and seals very well. I don't think the door would close if it were reversed - the thick part of the seal would be pushed out into the thinnest parts of the gap between the door and the fuselage. My parts catalog doesn't show the orientation of the seal. Anybody have a picture of a factory seal installation?
