As I have written before, Americans are extraordinarily lucky in their
freedom to do what they would like with these aircraft. 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.

Lots of ideas whizzing back and forth...
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.

| Subject: | Re: Air Tank Cocktail |
Craig, my feelings regarding this issue are easy to understand. 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.

On castor oil from: https://en.wikipedia.org/wiki/Castor_oil
Vegetable oils like castor oil are typically unattractive alternatives to
petroleum-derived lubricants because of their poor oxidative stability.[
30][31] Castor oil has better low-temperature viscosity properties and hi
gh-temperature lubrication than most vegetable oils, making it useful as
a lubricant in jet, diesel, and racing engines.[32] The viscosity of cast
or oil at 10 =C2=B0C is 2,420 centipoise.[33] However, castor oil tends t
o form gums in a short time, and therefore its usefulness is limited to e
ngines that are regularly rebuilt, such as racing engines. The lubricants
company Castrol took its name from castor oil.
Castor oil has been suggested as a lubricant forbicycle pumpsbecause it d
oes not degrade natural rubber seals.[34]
This site rates its suitability against various o rings materials

Oh, I thought antifreeze was so you could pee in winter.

| Subject: | Re: Air Tank Cocktail |
Basically it is two problems here: Rust protection for the air tank and lubrication/rust
protection for the lines/tubes/actuators.
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.
