Unfortunately, the situation in Europe is much more complicated, but we have been helping Bob Davy to install an M 14 P and a V-530 two-blade propeller, which we have supplied, into his Nanchang. However, UK CAA have made quite a meal of the conversion, asking for new stress calculations on the engine mounting arms and so forth. This is despite the number of M 14 P engined Nanchangs flying successfully around the world. I'm copying this email to Bob should anyone want to contact him directly.

I'll chip in my 2-cents: Years back I added a spritz of WD-40 to my CJ's pneu system, and very soon after a rubber seal in a firewall check valve completely broke down into pieces. So I was AOG while I completely cleaned out the system. I first opened & washed inside *every* tube with potent ipa/isopropyl alcohol (90% ipa, higher grade than the typical 70% ipa of first aid kits), quickly blew out each tube out with compressed air, and then lubricated with drops of castor oil. Replacing numerous check valves and the main SOV, the system has never worked or held its air better. That said, all I use now is castor oil & dessicant kits from Doug. We'll see if it gunks up over the years, but so far this is working well for me. Justin N280NC On Wed, Mar 8, 2017 at 2:59 PM, ChangDriver wrote: > > Well, well...what a way to light up the Yak list.

The owner of any Experimental Aircraft has tremendous latitude on what can be done with same. You as the owner can do whatever you want, add whatever you want, inject whatever you want, etc. I am not trying to tell you what you can, or cannot do, with your personal aircraft. Where I take exception is when someone starts promoting what they believe is a "logical and good idea" to other aircraft owners that has the POTENTIAL to cause bad things to happen, based on nothing other than personal logic and here-say, as in "someone else told me that this is a good idea", followed by the words: "I've done it and it works great!". Lots of folks think that if they do something, then of course it must be right, and that everyone else should do it too, and if any person in that chain of events OBJECTS to that kind of thing, they take it as a personal slight or insult. It was not meant as that. There is absolutely nothing personal intended. What I am saying is that the YAK-List, or *ANY* list is a wonderful tool for learning all kinds of good stuff. It also is a tool that can be dangerous to every pilot reading it. As I said, I followed the instructions everyone on the Yak-List at the time recommended and it came real close to causing me a gear up landing. The interesting thing here is that there has been absolutely zero response to my suggestion that the aircraft owner contact an FAA Maintenance Inspector and ask that person about adding ANY type of fluid to a pneumatic system that is not covered in the publications. The reason why not is that most everyone here would agree that the FAA is never going to bless such a move. So the bottom line is this: Just because you can do a thing, doesn't mean you should do a thing. And with my extensive experience with many makes and models of aircraft that use pneumatic systems, I would strongly suggest that readers of this list NOT put antifreeze into their pneumatic systems. You and your mechanic are welcome to espouse the practice. But I am also just as welcome to advise anyone reading this conversation that adding antifreeze to their pneumatic system has never been scientifically tested, is not advised by any maintenance manual, is not blessed by the FAA, or the aircraft manufacturer and comes with a potential risk. If the owners consider that risk and decide to follow your advice regardless, so be it. It is as I said to begin with, "their Experimental Aircraft". Just remember too, that should something bad happen and there is an accident investigation, you can count on the FAA to ask: "Why does there appear to be anti-freeze in your pneumatic system?" The answer of: "I read it on the YAK-List" is not going to count for very much. It is taking a chance .. plain (plane?) and simple. Every owner can made that choice him or herself. Mark p.p.s. Craig, at one time it was indeed advised ON THIS LIST to add MMO into the pneumatic system. -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com] On Behalf Of ChangDriver Sent: Wednesday, March 08, 2017 3:00 PM Subject: [Non-DoD Source] Yak-List: Re: Air Tank Cocktail Well, well...what a way to light up the Yak list.

For the tank I still believe the dried chain grease from spray cans to be no. one and it worked for me 10 years now. For the lines I dont know, but if you google pneumatic antifreeze you will find several products specifically for air brake systems. These additives will absorb water to a degree and provide some lubrication. If that works in trucks so it will do in Yaks. For the cautious you could put some Yak seals into that stuff in a jar for a while and see . No way would I use castor oil anywhere , same goes for WD 40, that forms gum or resin when dry as well . Also keep in mind that any stuff into the lines may wash down grease in the actuator downlock balls and springs to start corrosion there.
