    Here's my favorite sketch:

    There two truths buried in this. The first is that since a Mooney is a high performance aircraft, some parts are there for that reason and, like a sports car, they are expensive. The second truth is the fact that the plane is basically hand made, far more so than your average P&C brands. Again, adds expense when repair time comes. I drive a Mercedes AMG and I would not think of owning it without factory warranty coverage. The engine has a little plaque on it that the 'one man' signed after he assembled it. You can better believe that when that engine has a problem you had better have either a large checkbook, some insurance or be personal friends with that guy and live near Affalterbach. The Mooney is a bit like that. There's another stigma: A&Ps don't like to work on Mooneys. I have met some, good to have 'one man' who does like them.

    Good luck with that, it's a Mooney.

    I noted your S/N is 727, mine is 848. When was it airworthied?

    Anybody know what the profile shape is and dimensions are of the original door seal?

    Actually, it's a drive somewhere. It is also like a (real) cloud, here one moment, gone the next. You don't want a breakdown to rain on your maintenance parade. The good strategy is a layered approach. I 'photo scan' each new logbook page (airframe, engine, prop and even 'me'), so that way no one can say that I fabricated data. The hardcopies are in the fire safe (rated to three hours in a fire, should give the local firehouse enough time to douse the blaze). The digital are all over (laptop, desktop, work, home, I even think I have my pilot log on my iPad) including the cloud. I have data from my MVP-50 for the last five years of flying. Lastly, I have an Excel spreadsheet where I track everything...

    Speaking of MB, have you considered his service where he analyzes all of the data from your monitor?

    I just go with the yank test (as prescribed by the Guru of GGG). The new block seems tighter than the old one and now I know it will outlast me.

    Mine looked worn and probably could have gone longer, but 50 years is 50 years on such a critical part (there are horror stories out there of J-bars popping out).

    Puh-leez...the 182 is a soccer-moms SUV.

    I'm wondering if the kid was even with the FBO or the airport. Could be a budding Frank Abagnale.

    As other's pointed out, the gear locks into a heavy aluminum block. That block wears over time. Mine was 50 years old and I decided to replace it prophylactically. If you enter in to the purchase of a Mooney with manual gear, find out how old that block is. They are relatively easy and inexpensive to replace. Search 'manual gear' here on MS--you'll also note that the electric gear guys don't have half the cockpit humor that we manual gearheads do.

    Rob, I have been fascinated by this product and the fact that you developed it on an E is even better. I'd like to know what Mike Busch's opinion is on it. By any chance has he weighed in on it? Mike goes a bit beyond your hangar trained A&P (no offense to any of them intended here); e.g., Mike is a mathematician by training, having received his Bachelor of Arts degree in mathematics from Dartmouth College, Magna Cum Laude, and elected to the Phi Beta Kappa society. While at Dartmouth, Mike did pioneering work in computer software development. He went on to do graduate studies in mathematics at Princeton University on a National Science Foundation fellowship, and graduate studies in business administration at Columbia University.

    Grasshopper, don't, and absolutely do not fly one--especially a Super 21. If you do and later wind up with the 182, you will forever think back to that Mooney. It will haunt you, consume you, until finally you sell the 182 at a loss and return to the Mooneyspace (wherefrom this site derives it's name). After that you will fly happily ever after.
  15. HRM
    So you paid him?

    In an E those panels are Super.

    I think you have it, besides, there are lots of electret circuit designs out on the web. The reason that the red and green are interchangeable is because the internal amp doesn't care which side it get's voltage from and which side it puts voltage out (it's a bias, not a direct power connect). Imagine the battery is a pump, there's a pressure side and a sump, or return side. Now hook a loop of tubing to the pump, fill with water and switch it on. The pump circulates the water and everything is happy. If you switch the pump connections nothing changes (except the direction of the flow). Now pinch the tubing rhythmically with your voice. The tubing elsewhere will pulsate accordingly--that is what the electret element is doing. To get the effect the pump has to be on and keeping the tubing pressurized. Again, the effect will still work if you switch pump connections. Wait! What about the little amp in there? Doesn't it care about polarity? Well, it would if it was a BJT, but being a FET it doesn't care either. Extra credit for knowing what the acronyms mean...

    I've owned a number of Porsches and went to get a Macan turbo (at the wife's insistence no less!) and wound up with an AMG instead. I am now a convert, especially after driving a version of my car at COTA. 13K miles later I still get a SEG when I get behind the wheel. First time I drove it I was taken back to the day my dad took me to drive go-karts. As for Mooney, every time I TO I get a SEG. We had a discussion going on MAPAlist about non-Mooney CFI's. I prefer a young buck who has never flown in a Mooney for my FR. I always have such fun with them, but at the end of the hour they always ask me if they can do a landing. That in itself speaks for the marque.

    I believe it is called a Parker Annual. On the other hand, I side with Mike Busch in that an annual puts too much stress on an aircraft (and the pilot/owner!) to be a good thing. The most dangerous time to fly your plane is after an annual

    Hmmm...time to jump in. My IA told me to never have my logs in the plane, ever. So I have never taken them to him. He gets a flash drive with the scanned versions. Each year he gives me a set of stickers and I give him a check. He also gives me a few pages of AD sign-offs printed out by a program he has that keeps track of them. If I ever go to someone else, that is what they'll get. Being a very anal-OCD engineer, I have a multi-sheet Excel workbook with everything that has ever happened to my E, including flight time. The PO started it by copying everything out of the original logbooks. Yeah, he was an engineer too. I installed an MVP-50 four years ago and I have one second interval logs from every second the engine has run since then--EGT, CHT, RPM, GPS, you name it. Logbooks are a dinosaur, I just keep them in a fire safe for the next owner, who will get them from my kids when they liquidate my bird.

    There's a significant discussion on this elsewhere on MS, may get some hints there. I know my E has probably heard it all, but I am sure I uttered some novel expletives when I did the pilot side. If memory serves, a small vice-grip and some tape make the final assembly go easier. If an AD came up where that fastener needed to be removed and inspected each annual I would sell the plane.

    I am now thinking it is the Aerotech filter. I have a new one on order. It has been in the plane for 20 years. Mine is on the left and a new one on the right. I noticed that the pleats in mine are bowed and it looks like it has been sucked in. 20 years, time for a new one anyway.
  23. HRM
    Frankly, I don't know. I mean I have seen the filter and can probably find the pump and regulator. I am going down to the hangar tomorrow and pull the cowling (just give me a bullet) and take a look. I just wondered if anyone had any thoughts based on the data, like "Yup, the reg is blown" or something.
  24. HRM
    My vac pump died about a month ago and a week later I took it for Annual. Sure enough, pump disintegrated. The pic shows the flight (actually, my FR) where the pump failed, then the flight home from Annual with the new pump purring perfectly along at 5.5 or so, and then the flight last week where I kept getting vac warnings on my MVP-50 (4.5-5.5). Is this how a regulator goes south? I have not pulled the cowling and looked at anything yet. I have the full-monty Brittain system (Step, PC and 3-axis A/P). I also have the big filter that protects the system from a disintegrated pump.
