That’s the list of revisions, for better context on exactly what they changed and how, post the updated page 3. That’s where the real info is.

Only a half hour?

No worries. Our search function isn’t great. I use google with “mooneyspace” at the end. Heres the thread from a few weeks ago with lots more advice.

I’ve used Command Aviation at Bellingham and like them. Crown at PAE is good too but busy. We had a thread about this very location a couple weeks ago, see if you can search it out on google. Advanced down in TTD is very good and not that far.

Strangely, my gtx345 was using a G5 as the encoder and (after several conversations), garmin admitted there is an issue with that setup that can cause intermittent mode c loss. They even offered to send me a gae-12 encoder. Now I doubt the same issue exists with the g500txi, but I guess my thought is that it might not necessarily be an issue with the transponder itself. Maybe a wiring issue from the g500? It will need reasonable troubleshooting.

The reason I ask about your encoding source is that they said your mode C was intermittent. The mode C is the altitude reporting portion of your transponder signal. The transponder gets its altitude from the encoder which is a separate device.

Yes, but what’s its altitude source? I don’t think a gtn can be the altitude source? There will be some type of encoder hooked up to static air that provides it. Could be anything from an old school grey code box or a fancy little garmin one on the back of your unit. It’s where the transponder gets the pressure altitude. Strangely, the transponder needs a different box to do this for it. The transponder itself just takes care of sending out the different mode c signals, adsb, etc.

What is it using as an altitude encoder? I had this happen with a gtx-345 and it was actually the encoder.

There is supposed to be a “sacrificial block” where it goes through there, so yes, they put that in with the new one. That damage is actually pretty common. The newer models have some kind of a wrap on the tube and the “lining” in the hole.

I had to get one from Mooney a few years ago. Call top gun msc and see about ordering one.

The thing with the check valves is that they are probably original. They aren’t required to replace and they are expensive, so they are usually just left there until they don’t work.

He wasn’t wearing his tin foil hat properly.

Try this:

We have a thread on this with details from ~fall of 2024 if I remember correctly.

Funny, I have a pair of Bose X that don’t work in my new plane for unknown reasons as well z. All the other ones work fine and that headset works elsewhere…

Id especially check whether those fittings are correct as @N201MKTurbo suggests. Also +1 on check valve cleaning.

I just got a leak patched at Greg’s shop and concur - great experience, solid guy. They moved to a bigger hanger too which is nice. My tanks are still under warranty (previous owner had them done in 2022) but no chance I was flying to Ft Lauderdale and back for a leak. Greg did it in 4.5 hours labor over 3 days which is what he said to expect based on cure times and checking it after.

My wife was working on her license a long while back and bounced a 172 bad enough that she hit the prop and cracked the nose gear/firewall area. Went around, flew a nice pattern, landed, told the fbo that she hit pretty hard and they should look at the airplane. They said it was probably fine and she left. They called later that night and told us it was totaled! It was pretty ragged out…

Possibly I’m being too specific here, but if you’re at 65% power, you will have the same airspeed no matter how you get there - ROP, LOP, or Peak. If you’re in an NA airplane, you can only get MP up to a certain amount, then I agree with what you said - max power would be slightly ROP and yield the max airspeed, but in that case, ROP, LOP, or peak are different %power because you can’t get any more MP. In our turbos, it’s possible to set 65% power with different combinations of ff, mp and rpm, but they all yield basically the same speed (possible exception for prop efficiency or some other minor difference). If you are truly settling a % power, then airspeed will be the same ROP, LOP or whatever. Look at the link I posted above and you’ll see 3 different settings LOP, ROP and peak for 65% all the same speed.

Not true! The F-15E does everything better! Well, ok, except landing on a ship.

Mine too, maybe we got in before the increase?

One other note to add. At 65% on my engine, there wasn’t a huge difference in temps, but it’s there. LOP has the coolest cylinders, but slightly warmer tit. ROP has warmer cylinders but cooler tit. At 65%, none of the temps are even close to concerning. It does seem to take a well balanced fuel distribution and strong ignition system to get the tsio-360 running smoothly at LOP. Mine has gami injectors, fine wire plugs and relatively new mags. At 65%, you can just be a little LOP and still be good (no red box), so that’s easier than trying to be more like 50 LOP at 75% power.

Yes. In fact, the poh gives you a 65% ff of 11.3gph for the sb. I flew all 3 of these settings last week and put pictures in the link about Bravo operating costs. The true airspeed was within 1 or 2 knots for those 3 settings which proves they are all about the same % power. see the pictures on the last page near the bottom. POH (peak egt), ROP, LOP. All 65%, all ~same speed.

Mine shipped from airpower today! I ordered in January, and they estimated end of year at first, but then updated to end of may. There’s light at the end of this tunnel!

Not for a 430 card im guessing. Newer avionics use a sd card, but the 430 needs the garmin or jepp reader.
