Next up electrons flow from negative to positive. Prove me wrong.

Nah, the tail doesn’t rotate there or into anything. There was some impact damage that happened on the edge followed by some rain and that’s the result. LASAR and Mooney made those parts out of the worst polyester fiberglass process available. Leading edges will deteriorate if un-protected. You could drill off the Fillet and repair it, but I’d wipe it clean and throw a little epoxy on it and be done. -Matt

is that a Hartzell? I have several spinners with bulk heads attached with screws.

given the left side of the pic I would say some corrosion is going on there. Then some cracking as the metal thinned out. and your tail may be trimming up too far. gently lift the tail and see how much play is in it. (this is a walk around item)

Well, maybe if you expect a HUGE inrush current a slow-blow would be appropriate. Thing is, it is not commonly understood that even a fast-blow fuse is really pretty damn slow at just over its rated current. E.g., a 3AB fast acting 10 Amp fuse will take over 15 minutes to blow when at just over 10 Amps! Even at 20 Amps it will take 4-5 seconds! So, just how long do you really want to wait when the circuit is drawing over the fuse's rated current? https://www.littelfuse.com/assetdocs/fuse-322-datasheet?assetguid=4716bb79-a4c9-46f8-a462-76ba7e6af5ae

My B-In-Law go his grandfather's old car when he was heading off to collage in the 60s. Changed the oil in the car with some of that great modern degergent oil that was being advertised. Got about 60 miles and the engine seized up. When they eventually got it to a shop, the mechanic said it was because of all the crap that new detergent oil broke free and it got everywhere inside the engine.

I found a reference to an IVSI in the GI275 manual, but it seems to be associated with TCAS II. So I wonder if it is available for GA or you need a different version of the 275.

Yup, a 1/4-wave stub antenna is generally omni in the plane normal to the antenna axis, and since the DME or transponder antennas are typically on the belly to minimize shadowing, it has to be small and would be more problematic to be full- or half-wavelength. With the natural ground plane of the airframe, it also makes a 1/4-wave a bit more efficient. Antennas have tons of weird and subtle tradeoffs which makes it interesting to see the choices that are made in various applications.

There is a requirement in Canada for a diversity antenna, typically on the roof, for the 1090ES transponder/ADS-B signal. That may be what that was, and if the aircraft was in Canada, but is no longer, that may explain why it hasn't been addressed. If the transponder does have diversity capability, the diversity output channel should be turned off to prevent damaging the power ampifier in that part of the transponder. This is just me guessing what that was, but it shouldn't be too tough to check the transponder and make sure any available diversity outputs are turned off.

I've noticed that, that the G5 VSI is pretty responsive compared to the air VSI instrument. I've adapted to using it more as it does seem pretty useful. I also fly G1000 aircraft and haven't really paid much attention to the responsiveness of the VSI in that system. I'll likely be more attentive to it just to see the difference.

If you do have a fuse, make it a slow blow.

FWIW, the buss voltage with the engine running is 13.6 to 14.1 depending on your regulator and how it is adjusted.

At the recommendation of our old timer coastal IA, we used to “fog” our Mooney with MMO as an airframe corrosion inhibitor before there was Corrosion X, or at least before we knew about it and it was readily available. I’ve never put it in a crankcase or a fuel system, though. Agreed with Mitch. It smells good.

@mikechaf BTW - the standalone Inogen BA-503 External Battery Charger (for the G5) draws 65 W. Assuming the same charging circuitry in the G5 then operation on high and simultaneous battery charging can draw 125 W. If power at the socket is 12.5 VDC, then your max draw is 10 Amps.

If you can’t find any other info for the lighter socket, just use the wire ampacity charts in 43-13.1B. As far as the socket is concerned, most are rated at 10A, some 15A. I found a specialty socket rated at 30A. Chief Aircraft has a PMA socket for $97 that is rated for 8A continuous and 10A peak.

Clean the connection between the transducer and ship wiring first. That's the easiest fix and a high probability cause.

Yes 61 W on high is correct. The charger supplied with the G5 or Rove6 output for simultaneous charging and operation is 24 VDC at 5.0 Amps. So you should be good with 10 amp CB. on your 14 volt system.

From the service manual

Probably a sensor issue. Even if it was true, high fuel pressure isn’t an issue. I asked the engineer from Precision Airmotive how much fuel pressure the servo can tolerate. He said 75 PSI. There really aren’t any failures that will actually make the fuel pressure go high. The fuel pressure is controlled by the spring in the fuel pump. There have been a few people who have had this problem. It was always the sensor. It never hurts to check the wiring and clean the connectors.

It might be helpful if you identify the model of airplane you purchased. Maybe even the year. At this point you have a lot of catching up to do on the matter of aircraft ownership.

Time to learn something more about my plane- on a return flight today, the fuel pressure indicator went beyond the redline on the high pressure side. tries cycling the boost pump- no change on idle, it dipped into the green but went even higher when I added power on the ground. who has seen this before?- assuming its a transducer- but looking forward to others thoughts Thanks, Rob

These things rock! Got us above the thin smoke layer across Oregon and northern Nevada. Yes it took 17,500’! But she’s real fast up there. Got to see Burning Man too. 6 in the pattern on adsb as we went by - no thanks!

Digging through the logs, I found "installed aux power jack in panel." back in 2011, but no mention of fuses, what circuit breaker it was on, etc. Similarly no mention of these jacks during the more recent glass panel upgrade in 2019. Once I get some replacement fuses I'll play around with the circuit breakers to see where the two sockets are counted with a multimeter. ragsf15e, where did you see that the Inogen G5 could draw 12.5A? If you can trust Google's AI, it says the highest setting (flowrate 6) consumes 61.5W. The single battery stores 46.1 W-Hr, and the spec sheet says 4 hours to charge. Putting that all together running off a 12V aircraft bus voltage (and assuming 90% charging efficiency) I get about 6.3A total power draw off the socket, which matches well with the 7.5A circuit capacity that Tom from Windblade suggested. Good to hear, PT20J. I'll see if I can verify the wire gauge before I jump to swapping out the fuse. Are there any other gotchas I should be worried about? I'm suspicious that the 2x 5A fuses could be explained by driving both of the sockets off of the 10A circuit breaker.

Throwing in a pint of Stoddard Solvent would do the same thing. It’s an old shade tree mechanic trick for flushing out sludge. But generally, they only ran the engine for a short time before draining.

Hi, welcome to Mooneyspace and Mooney ownership. I've seen this all the time, there are mechanics that try to keep the cost of ownership down by letting little things slide, and then when the plane is sold the next guy discovers a can of worms. I think a lot of the issues found are relatively minor and easy to fix. The fuel leak is obvious, there is a Mooney SB somewhere that describes allowable fuel stains, and I am sure this exceeds this. I think the previous mechanic told the seller that it's time to reseal the tanks ($$$) and he elected to sell. But both the annual and pre-purchase inspection should have picked this up and reported it to you. There's always a little e of catch up maintenance to get an airplane up to a new owners standard, hopefully it levels off. The fuel tank leak is going to be expensive, but even that will add some value to the plane when you sell in 10 years time. Aerodon
