M20K TIT and CDT Sensor/Probe Sources

[Q The Engineer]

Guys,

It looks like the probes on my CDT and TIT are both belly up.  I chased up the Mooney part numbers and a few alternatives.  From what I could find KS Aviation offered a cost effective solution. I contacted them today and they aren't in production due to supply chain issues and aren't sure if they will go back into production.  Does anyone have any alternative sources?  Here's what I've dug up on part numbers:  

Description         Mooney Part #           QTY      Notes

TIT sensor            880055-505                   1         Alternate part numbers Alcor 86309, KS Avionics A002C-30
CDT sensor          880006-501                   1        

Thanks a ton, 

Aaron

Aaron,

Did you ever find an alternative to the Alcor TIT probe?  I've been working with KS Avionics but no luck so far.  The Alcor probe in now $540 at Spruce...crazy.

Would jpi have a replacement sensor since you get all probes when you buy a new jpi 900 for example. 

[231MJ]

Very good idea.  I have a call in to JPI - they are busy today.  The factory Mooney TIT probe is a little unique in that it's and ungrounded probe with a higher resistance of 1.6 ohms (most probes I see are less than 1.0).  I hope JPI can help.

JPI probes are not compatible with the Mooney TIT probe.

Thanks, Paul.  Confirmed by JPI.  Got any other ideas?

Buy a jpi 711 engine monitor with jpi probe probably cheaper than the mooney probe and it’s certified primary for the tit. It’s a 2.5 inch gauge so fits in the same hole as the tit or clock etc.

That doesn't solve his CDT issue which is part of the factory TIT gauge.

[Pinecone]

And it makes a lot of sense to spend 3 AMU, plus install to avoid buying a $540 probe.

[Will.iam]

Yea the jpi 711 no longer available for sale. I guess if it’s not 1amu or more it’s not worth selling.

That's too bad as I too am in need of an alternate to the Alcor 86309.  I was going to call KS tomorrow, but it sounds like they may be out of business?

[231MJ]

KS is still in business.  I went there last week to get my probe back.  He even tested it and confirmed it was still functional.  He's in poor health and would like to sell the business (Dynon was going to buy it and then backed out).  It's worth a try - call him because his wife does answer the phone.  It might work out - or keep checking ebay.  

[KWSmith]

Yes, KS Avionics is officially out of business.  I have been waiting them for over six months for a TIT and CDT probe and they just let me know that they are now (2 March 2023) are unable to complete the order.  The best I could understand from Pat or Bill is that a company called Hoses-Unlimited has purchased the rights to make the probes.  So far I have not found the company.  I'm still hunting and will let all know if I fine any probes.

How about https://www.hoses-unlimited.com/

Second hit on my search engine.  Can it be that simple?  They don't appear to be an aviation company.

KS Avionics has been purchased and moved to North Canton , Oho. We are in the process of getting everything retooled and up and running. There are a limited number of of probes now available and the availability will be increased as we can get the different lines set up. Bill and Pat ran a quality operation, and we will maintain that level of quality.

We have been in the aerospace industry for over 40 years and presently supply NASA, SpaceX and Blue Origin with specialty applications and general aviation at AircraftHoseStore.com

There will be a slight delay in orders but hope to be up to 100% soon.

Thanks for the heads up, and welcome to MooneySpace!  Come visit as often as you can.

Thanks for the feedback gentlemen.

It makes perfect sense to every real pilot on this forum, just don’t tell my girl.

I talked to KS Avionics yesterday and it looks like they have a TIT probe available for at a reasonable price point.  If I can dig up the specs for the CDT it sounds like they can make them too.  Anyone have the print for the CDT?  I hear it's a thermistor and not a thermocouple.

Stupid question… how do I find out exactly what TIT probe I should have?  I looked through the logs and they show a JPI 900 was installed in 2018 with all new sensors.  Then a g3x with gea was installed in 2023 and “reused all sensors except mp and ff”.  But if the jpi tit isn’t compatible with the g3x as you stated above, then do I have the correct probe? And what is the correct one?

Thanks,

Drew

I was referring to the Mooney OEM B&D TIT gauge and probe which can’t be replaced by a JPI grounded probe. But i don’t know if the JPI probe is compatible with the Garmin G3x EIS - would have to refer to the installation manual. But if your TIT is showing 50-100F above your EGTs it’s probably doing fine.
Still though TIT probes should be replaced about every 500 hrs or when they start to read lower since they suffer from tip erosion. Yours might be getting worn out if from 7 years ago depending.

Thanks that makes sense!  I do think it’s 7 years, but it’s only about 400 hours (engine oh 3 years ago).  I’ll look at getting it replaced next annual, but I think it’s looking reasonable compared to the EGTs.
