Wingover

Just wanted to thank you for your help. I found out that the servo ground wire came out of the crimp ring. I installed a new ring and all is good!

@Jake@BevanAviation I get it now. So the rocker switch (up/down) on the AP works, also the electric trim works (although it obviously disconnects the AP). I guess the trim servo works? Also the ground test pass so the AP thinks it is all okay. I don’t get the slow oscillation, it’s just like you never pressed the alt hold. I have to hand fly (push/pull the yoke) to keep altitude. Any idea where to go from here?

@Jake@BevanAviation thank you for the explanation. It just stays at whatever attitude the plane is prior to pressing the alt hold button. I was climbing at 600fpm and when I decided to level off, I pressed it but noticed that the plane was still climbing. After that I tried a few more time while fairly level but it was like hand flying, didn't oscillate or hard pitch. What do you mean by "tach generator"? the same one that is on the engine for the RPM gauge??

Meant to say 2017, not 2007

It doesn’t hold the altitude when I press the alt hold button. Used to hold it well when pressed.

It was installed in 2007 as far as I can tell.

I don't have pre select but the interesting thing is that I got a message on my Garmin GPS "Pressure altitude source inop or connection lost” so I thought it could be related. I have a G5 and GTX330 with Alt so I was wondering if it was getting the alt source from one of them.

I will have to check if mine are (I have two altimeters) are encoding or not.

I am curious where does the KAP AP get its alt source (GPS, G5 or transponder baro?)? Went flying today and noticed the alt hold wasn’t working. Everything else was working fine (heading bug, electric trim etc). I am wondering if something got lose in the connections. The AP pass the preflight test so it all seems fine.

Why not let PMM in Belgium rebuild it?

Is that with TKS?

How did you know the metal was from the governor and not something else?

Don, What is the useful load with AC and TKS?

From all the 252 posts on here it seems the 175 ktas is achievable at 75% and at 12,000 and above but more like 165-170 is realistic to plan for.

Most of the time the trip is 700-750 with the occasional 850. I figured 17GPH at 180Kts is around 4 hours with IFR reserves the 750 should be a no problem. Usually I don’t have to fight the wind here in Europe and we are a bit flexible with the timing.

Any specific reason against the Acclaim?

Appreciate the feedback. My J in Lycoming and I am happy with it. I am aware of the debate that Continental is more "delicate" and needs more work if flown not by the book but I don't have real experience behind it to say that I have to avoid it.

I am looking to go from my J to a turbo. My usual trip is 2 people (total 300 Lbs) with luggage (around 80 Lbs) and around 700-850 nautical mile each way. Highest mountain is 12,000 ft on the way. We have done a few in the J (small deviation to avoid the top of the mountain) but it is just over 4.5 hours. We are looking to "shave" an hour off so need something in the 180-190 kts range. Also, need to be able to climb for weather in the fall or winter. This is all flying in southern Europe in winter and to central Europe the rest of the year. I see some of the people here who went from a Bravo to an Acclaim and back and some that just don't see the Acclaim as "better" than the Bravo. Could I get some feedback from those who actually had both and chose to either go back or stay, as to what were the deciding points?

Just following up on this in the hope it will help @ajudson and others. I spoke with Frank Crawford at Mooney and he sent me some drawings (attached). he also mentioned that Teledyne might be able to fix the B&D parts and Mooney advised customer to call 310-765-3600 ask for help.

I ended up buying @PT20J 's tach and generator (I guess he has enough money now to buy an Acclaim Ultra) . I wanted to thank @Aerodon for the time he took to try and find out the correct part number.

Skyman says they don't have the tach generator....

Try switching the probe with another cyl and see if the problem moves.

You are right. They are connected in a series so I would think it would make a difference.

Do I need to disconnect the wire from it or it doesn't matter?

Trying to figure out if my issue is the gauge or sender. The gauge shows less than full when I fill the tank. Right now I have about 8 Gal and when I pull the outboard float up it doesn't affect the gauge. Where do you start the diagnostic process?
