@Little Dipper Make sure the TKS panels are very well protected. If they get damaged by solvent it would require panel replacement $$$$. The panels are held on with sealant and usually riveted in the corners. 99% of the time when a panel has to be removed it ends up getting destroyed due to the separation of the backplate and front plate. That is going to be a nice looking Mooney. Can't wait to see the end result.

@NickG I sent you a PM. Feel free to reach out with any questions.

@dkkim73 in reference to the control panel, it depends on what style is installed in the aircraft. If you are able to email me some pictures of yours, I can advise on the easiest way to access it for testing.

Start by running the windshield pump 3-4 times. This pulls fluid from your tanks through the main metering pump(s). This primes your main pump. If you are having issues with dry spots on the panels let me know.

@Patrick Horan the level of fluid in the tank is not associated with any high or low-pressure warning (unless you completely run out of fluid). Low pressure warnings typically occur in warmer weather or if there is line disconnected in the system. The easiest way to drain the tank is to disconnect the 3/8" line, which runs from your main pump to the strainer (see images).

Typically, in Mooney's, if the OAT is 59 degrees Fahrenheit or above you can get a low-pressure indication due to the viscosity of the fluid. @amekler I sent you a PM.

@redbaron1982 I sent you my contact information. Feel free to reach out and discuss the fluid quantity issue. Level senders can stick if the system is not run frequently, but the more common issue is the float filling up with fluid and sinking to the bottom of the tank. This doesn't occur often, but we have seen it happen.

We recommend you run the system at least once per month. Start by exercising the windshield pump. This pulls fluid from your tank through your main metering pump(s). Then run your main pump until the panels wet out sufficiently. We run ours when we take trips. Run it in cruise, let it drip on the ramp, don't run it on the way home and it should be fairly dry once you get home. You should be able to see fluid all the way down the wing in flight. See attached picture. @Danb I sent you a PM with my contact details if you have any questions.

@r0ckst4r The convoluted tube is P/N 1120 Inside the convoluted tube is an inline strainer P/N 4664 This tube/strainer feeds directly off your tanks to you main metering pumps. My best guess, based on the pictures, is the convoluted tube my have a small crack at or near the hose clamp causing a slow leak. Further investigation would be required though.

@PhateX1337 FIKI Mooney installation (no fluid): Weight: 51.1 lbs Arm: 80.1 Moment: 4093.1 Fluid weight and balance information is located in your Flight Manual Supplement Section 6. Although TKS is not typically required in the warmer months we still recommend running the system AT LEAST once per month (ideally twice). This prevents air/water from collecting in the system. Common things we've seen with inactive systems include main pump corrosion, filter corrosion, windshield pump failure and panels not fully wetting out. Recently had a system that wasn't run in 3 years (not recommended!!!). After a bit of work, panel purging, and pump overhauls the system is now fully functional. If you are trying to save on weight the minimum dispatch level of fluid is 3.8 gallons, so you don't always need to fly around with full tanks. Just make sure there is enough to run the system on occasion. We typically run ours during cruise to see the entire wing wet out, and then shut it off. By the time we are back at our hangar the system is dry enough so it does not create a mess on the hangar floor.

@glenn reynolds This is the first fire sleeve failure I've seen. Good catch! Stall strips should be checked on a regular basis (preflight?). The sealant used now is PR1221 B1/2 or CS3204 B1/2 (I have instructions on installation and sealing if needed). This has proven much more effective than the older sealant, which can weather and crack. Should a stall strip come off make sure the feed tube is secured. If the feed tube breaks off flush with the panel it would require a panel replacement $$$. Sorry to hear about the belly tubing. PM me with the installation information. Thanks!

@Fly Boomer I sent you a PM

You will have to access it through the belly, but inboard of the right wing is a finger strainer. Disconnect the line going to the strainer and be ready with a bucket.

I would advise against letting the TKS system sit unused for an extended period of time. A few thing we've seen from inactive systems: 1) Corroded filter bowl $1,300 2) Seized windshield pumps $900 each 3) Corroded main metering pumps $2,860 each 4) Panel purging required $ is dependent on labor We recommend running the system at least once a month. Ideally twice a month.

Improvements on panel production and design. Plus the addition of landing lights added in the wings (on some models) required different panel placement. No-hazard system is for the M20J, M20K, M20M, M20R and M20S. FIKI is for M20K, M20M, M20R, M20S and M20TN.

FIKI: dual main pumps, dual windshield pumps, additional pressure switches (3 total), different proportioning units due different panel sizes. Certified in 1995. Ho-hazard: one main pump, one windshield pump, two pressure switches, different leading edge panels. Certified in 1988.

That looks good! The ice light would have to come back to us to get repaired with the original glass, so I like your solution. In the no-hazard installations we used our ice light. On most FIKI installations they were factory installed, so Mooney came up with their own ice light. That is why the ice light location is different between the FIKI and NH installs.

We just bought one from Air Power Inc. They had the best price we could find for the battery in our Columbia 400. Here's a link to the one you are looking for (ready to ship 4/3): https://www.airpowerinc.com/rg-35axc
