TKS-equipped Mooney Maintenance Check

[CAV Ice Protection]

If your TKS-equipped Mooney has over 2,000 hours, then it's time to send in your pump for preventative maintenance checks and services.  

Call the TKS Repair Station at 913-738-5397 for more information.

[StevenL757]

Appreciate the heads-up post.  For those with FiKi designations/STCs on such aircraft, there are multiple pumps onboard.  Please can you expound on these services - including tasks involved, costs, turnaround times, etc. for those considering such work in the near future?

Regards, Steve

[CAV Ice Protection]

Due to the specific nature of each aircraft system, please contact Tom Stellwag, Repair Station Manager, for more information.

Tom can be reached via email at repairstation@caviceprotection.com or by calling 913-738-5397.

How do I adjust the tube sending TKS fluid to my spinner/prop.

Got into some ice today on descent and after landing the engine cowl was smoking with tks fluid all over the engine. The prop had some ice.

The fluid is not flowing into the slinger ring.

The fluid is not flowing into the slinger ring.

In September I found the "J" shaped tube that's supposed to squirt TKS fluid into the prop slinger ring had rotated 180 degrees on my M20R.  It was hosing down the prop hub.  The techs turned it back around, tightened it properly & it is working normally.  

The prop deice line passes through the firewall in front of the pilot's feet, runs over the left top of engine and to the slinger.  There are about 4 connections from firewall to prop.  You can see it all with just the top cowl half removed.

That J shaped tube is what I am talking about. Where is the "tip" of the tube suppose to be? Should it extend into the vee shaped slinger on the spinner?

Or should it be "backed off" with a space between ?

This is good info..glad to see cav aero posting info...could you lower cost of filters please?

It should be aimed up and end just short of the slinger V shaped ring.

Please see the attached tks installation drawings.  They show the orientation of the "j" nozzle.  Mine has the fitting safety wired so it won't come loose as easily.

Correct.  I've had to replace two of these over the life of the aircraft so far...one that was part of my old MacCauley prop slinger ring kit, and another with a different model of feed tube that goes with the Hartzell kit.  If anyone needs help with this, happy to work with you over the phone.

Are the pumps due overhaul based on aircraft time or pump running time? 

[carusoam]

The TKS drawing does shed some interesting light on what you get with all that investment.

Thanks for sharing those details!

Mine was safely wired neatly but the fitting was loose, probably incorrectly torqued during engine reinstallation. That allowed the "J" pipe to rotate.  

Thanks for sharing the TKS drawing set.

Thanks for posting these, very valuable for the file.

It would appear the the recently replaced nozzle on my non-FIKI K was not aimed correctly...

Also, the nozzle can get into an harmonic vibration and break. This happened to mine, the fix is a little bit of prc at the base of the nozzle, I noticed you don't have it done. CAV sent me the instructions on how to do it. It's a known issue.

Thanks. I recall recently reading this comment about the vibration issue. I am going in for an annual at the end of January and will get it sorted. Any chance you can share the instructions?

 

Thanks,

This is all I have. Unfortunately, I cannot find the E-Mail from CAV. If you call their support number, I'm sure they can send it to you.

Another potential hazard to the nozzle is the tether connecting cowl plugs.  It can pass into the gap behind the spinner, and if you're not careful, you can find yourself yanking on the nozzle.  I'm always careful to route the tether in front of the blades.

That looks easy enough. Conical glob of RTV as vibration damper.  Thanks,

[Cruiser]

Thanks for all the great info. I am going to the plane tomorrow and will take some pictures also.

 

[BradB]

While to cowl was off for another reason, we found that my 'j-shaped' nozzle was broken.  My mechanic ordered a new one, but it doesn't seem to be the same part.  Does anyone have the correct part number for the nozzle?  I'd really like to have a new one installed before Friday.

I'll attach pictures of my old one and the new one that was sent.   I'll also add the vibration damper on the new one.

Thanks,

Brad

I would think age would be more important than hrs. Some people fly that much in 10 years...others might not reach that mark in 25 years.
