Dennis Savarese" Subject: Re: Yak-List: Re: Air Tank Cocktail Interesting. I'm wondering what the antifreeze does to the rubber seals in the actuators and unlock assemblies? Just for grins, try soaking a couple of the replacement chevron seals for a few days and see if they swell or any sign of deterioration. Let us know the results please.

I would ask him what other aircraft pneumatic system has he experience with where he unilaterally added antifreeze because he "felt it was a good idea". And I'll put it out there in another way. How about if your A&P mechanic calls an FAA maintenance inspector and says: "Hey, I'm working on this Chinese and Russian aircraft that has a pneumatic system used for flaps, landing gear and brakes..... what are your feeling about me adding ANTIFREEZE into the system, because hey... it is a great lubricant, absorbs water, has rust inhibitors, etc., etc. Do that and let's see what they say. RTFM (Read the Manual) Mark p.s. I've been working on Russian aircraft for 18 years now, and military aircraft for 47 years. Just FYI, military aircraft also have high pressure pneumatic systems and we do NOT recommend adding antifreeze to the system.... ever. -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of ChangDriver Sent: Tuesday, March 07, 2017 1:48 PM Subject: [Non-DoD Source] Yak-List: Re: Air Tank Cocktail A&P in my area who has been working on Yaks and my CJ for many years has always recommended and used antifreeze in the air system.

Not too good for aluminum, and I don't know how long term exposure would affect steel.
