A very common thing on 90's Mooneys is that the switch in the baggage compartment gets bumped after taking out luggage after a trip and the battery dies and gets to a low point where it can't be recovered. I did it once on a '96 Mooney Bravo. Later on Mooney wired in a delay circuit which turned the light off after 10 minutes. I would be surprised if a new Concorde battery didn't take care of your problems.

If it's at 22 volts you're probably not going to recover the battery. Has he tested your battery relay? What model/year Mooney do you have? Is there a baggage light? Was it left on?

The last Gill I bought lasted 20 months. I inquired about the pro-rated warranty. They were going to give me a $100 credit if I bought another Gill. Not a chance. It sounds like you have a dead cell. You don't need an A & P to change out your battery. Highest chance is that it is the simplest thing - a bad battery, especially since it's a Gill.

Is your battery a Gill or Concorde? According to the logs how old is it?

I think that was some tribal knowledge that disappeared when the original 252 engineers weren't around when the Encore was introduced in 1997.

Here are some other portions of that trip . . . I think:

Beautiful airplane, congratulations. Getting it home may be challenging, but once it's home it should be a lot better choice than the last one you were looking at:

In early 2014 I bought a 1997 M20K (Encore) with about 750 TT. The cylinders had been replaced with new Continental cylinders before I bought it at around 645 hours. When we took the top cowling off the first thing I noticed was that the rear baffling material was "lazy" and blowing back, meaning that almost no air was being forced down over the cylinders. During the annual I had them replace the baffling with Gee Bee baffles. Over the next month or so a few pleats had to be cut to get them to lay perfectly, but I never had a problem with the cylinders overheating during the summer in Texas.

Over in Houston you don't have to shovel humidity . . . but you can if you want to . . . lol

In developing the Acclaim in 2004 and 2005 they were wanting to reclaim the fasted production piston single which then was held by the newly introduced (2004) Columbia 400, which had a book speed of 235 knots with a 310hp TSIO-550 and fixed landing gear, 15 knots faster than the Bravo (220 knots). The Acclaim came out in 2006 with a top speed of 236 knots with a 280hp TSIO-550. If someone ordered a Rotating Beacon on an Ovation or a Bravo (they were not standard), they were always mounted on the belly. I don't think you'll find an Acclaim that came from the factory with a rotating beacon since they were leaving no stone unturned in trying to squeeze out every knot. Two years later on the Acclaim S, in addition to some airframe tweaks and a new prop, they made the step removable so they could squeeze a little more out of it to get from 236 max on the Acclaim to 242 knots max on the Acclaim S, still with 280hp. The prop made the biggest difference, but all of the other things they did added up.

That's a tough route in the winter without TKS. Eastbound helps though on the groundspeed. I would start by making sure that it's able to run lean of pean for max range. That usually includes Tempest Fine Wire spark plugs. A Turtle-pac would be a good investment. Mooney SERVICE INSTRUCTION SIM20-133 talks about OPERATION OF OVERWEIGHT AIRCRAFT. A couple of times I've thought about buying an airplane that was a "good deal" from overseas but by the time I added up everything the math didn't work.

If it is crossing the N. Atlantic in the winter they need to do it right. If every drop of avgas matters it should have a ferry tank installed.

Yes, I mentioned it for @Yetti who has an M20S with an IO-550 Continental.

If you end up doing your avionics upgrade you also might have another option - there's a small B&C alternator that can go where your vacuum pump is now. It provides 20 amp continuous and 30 amps max for essential things. In my Acclaim it can run the things on the Emergency BUS and it was installed at the factory. The alternator isn't listed specifically on the STC but there have been examples of 337s where it has been added, possibly with a field approval. Just making sure that both of your batteries are (1) Concordes and (2) have good capacity left makes flying with one alternator a little less worrisome.

Bob Kromer, the test pilot for the 252, gave presentations at MooneyMax in 2022 and 2024 where he told us about that. In 2024 at MooneyMax we were touring the factory on Saturday morning and I noticed a picture of the 252 from back in 1985/6. I asked Bob if that was him in the picture . . sure enough it was. I think you'll also notice in the picture if you enlarge it that the cowl flaps are "closed", but in 1/2 inch trail as recommended. Later that night Bob was nice enough to get in the picture with a couple of 252 owners, @MarcJohnson (L) and @shawnd (far R) and an Encore owner @Marc_B (C) .

Lycoming TIO-541-A1A I believe

I would bet that your cabin door seal is letting it in. You might also check to see if you're missing any camlocs on the belly.

Surely this price isn’t correct? Unfortunately I think it is correct. But that still doesn’t give you the right to call me Surely

One thing to consider: On the ground what do your cowl flaps look like when they are at the "closed" position that's shown on the instrument panel indicator? If I remember correctly they should be about a 1/2" open. If not you will run too hot and lose a couple knots. In the test flights when developing the 252 they found that 1/2" open at the indicated "closed" position gave it the best cruise speed since the air going into the cowling had to have an exit to be efficient. Sometimes a well-meaning mechanic or owner will adjust the cowl flaps so they are really completely closed, which they shouldn't be. Also if you have a known TIT probe (meaning new) you won't hurt anything if you set it at 1580 and it bumps up to 1600 as it varies. However I would be very suspect if it's an old probe since the probes indicate low after they are burned up.

If you quote @rakesb, like I just did you, or mention him with an "@" in front of his name he will get notified that you posted on this thread.

Sorry, I mentioned the wrong Don. I think @Aerodon may have a set or two.

@DonMuncy might have a set

David, you were the first Mooneyspacer I met in person. I bought an Encore in February 2014 and had Dugosh do a few things to it after I bought it. You'll probably remember that in April 2014 you drove me from 5C1 to Kerrville to pick up N40FM when they were finished. I appreciated it then and still do!
