I owned a (converted) M20D for 9 years and now I've owned my M20J for the same length of time. The J is slightly more pitch stable than the D but I never really found the D to be unstable. It's just a difference I noticed when I upgraded. The difference in rear seat leg room is meaningful. I'm 6'5" and there was essentially no room behind me in the D. My wife (5'4") rides comfortably behind me in the J. The rear seat of the D was ok when the kids were in little and in car seats but they quickly ran out of room as they grew. The rear bench seats in the two planes are also slightly different. The angle between the seat and the seatback changed. In the D the angle was more acute and less comfortable. I no longer get complaints about the comfort of the back seat.

The SDS I found online says Corrosion X is >90% petroleum distillate so it's hydrocarbons like fuel or oil which shouldn't affect sealant. The rest of it is some proprietary amine in some proprietary percentage. I wouldn't expect that to have much effect on sealant but it's hard to say for sure.

Ethylene is a gas and isopropyl is a hydrocarbon substructure. Are you referring to ethylene glycol and isopropyl alcohol? Methyl is also a hydrocarbon substructure and wouldn't have much affect on something designed to resist fuel or oil. Acetone and MEK are structurally similar ketones. That's likely what's impacting their ability to soften the sealant.

I don't have any personal experience with One Wheel devices but if you're considering getting one it seems relevant to know that the CPSC has issued a safety warning about them. The company has not agreed to a recall. https://www.cpsc.gov/Newsroom/News-Releases/2023/CPSC-Warns-Consumers-to-Stop-Using-Onewheel-Self-Balancing-Electric-Skateboards-Due-to-Ejection-Hazard-At-Least-Four-Deaths-and-Multiple-Injuries-Reported

Two points: 1) Atmospheric gas is normally represented in ppmv (parts per million volume) not mass even though they write it as just ppm. Details here: https://climate.nasa.gov/news/2915/the-atmosphere-getting-a-handle-on-carbon-dioxide/ 2) I think your calculation is off by an order of magnitude. 23 trillion is 0.4% of 5.5 quadrillion not 0.04%.

Installation instructions are here: http://sarasotaavionics.com/manuals/appareo/Stratus-Power-Installation.pdf It specifies a CB but no fuse. It looks like the power can easily be disconnected from the back and you could use a multimeter to determine if power is getting to the unit.

When it says something like 25-0640 THRU 25-TBA it means that all s/n above 25-0640 are included. So it looks like VI and VII are both valid for your plane for part #3.

What kind of panel upgrade involves removing right seat brakes?

There was a recent thread on this.

Which way did you bleed the brakes? If you bleed down it is almost impossible to get all the air out of the system. Pressure bleeding up from the landing gear seems to work better.

Wasn't it 201 mph rather than knots that inspired the name?

Don Maxwell posted on Facebook recently that he had received a shipment. Maybe @Pmaxwell knows if they still have any.

Starting with the J they were certificated under a mix of CAR3 and Part 23. You have to check the type certificate to determine which paragraphs from Part 23 are applicable for each model. The amount of Part 23 used increases with the more recent models.

When I had an M20D I asked Mooney about retrofitting rear shoulder belts and they told me the short body Mooneys don’t have the needed tubular structure to attach them. I assume this is why Clarence had to make a custom bracket. My M20J has factory rear shoulder belts. I’ve never really looked at how they’re attached but the M20J has an additional steel tube, not shown in Clarence’s diagram, in the right position and I assume the shoulder belts are attached there. The extra tube is part 73 in this diagram. Presumably you can install rear shoulder belts the same way the factory did without too much custom work.

What if you install it in a Mooney Rocket?

Those round areas look like they could be filler and paint over a hybrid weight.

If it's the master switch or voltage regulator you can usually see rhythmic fluctuations in the ammeter that correspond with the changes in lighting.

I chased a similar problem for a while. We focused on the master switch based on the many threads here and Don's writeup. That didn't fix it. Eventually we replaced the voltage regulator and that finally fixed it.

Automobile gas pumps are grounded through the hose. The metal handle/nozzle makes contact with the car and there's a wire embedded in the hose.

Why are you using an expensive aviation battery instead of a cheaper automotive battery?

The maintenance manual shows how to classify intensity of fuel leaks and tells you which do and do not constitute a flight hazard. Is your A&P referring to the manual when making these decisions?

Does anyone here take their plane to the Mooney factory for service? What is their procedure for jacking?

Longview is less than 100miles from Arkansas. Not exactly the western part of Texas.

You're absolutely right, as always. I was just commenting on the fact that he hadn't seen any record of AD compliance in his logbook.

There's a related Lycoming service bulletin (543A) dated August 30, 2000. If your engine was assembled/overhauled after that then there shouldn't have been any AD action needed.
