Subject: Yak-List: WB Article.
About a year ago I did an article for WB mag. Finally got published in Marc
h issue. It "re-introduces" the CJ-6. The reader will be treated to a Ron M
alec photo of a formation lead by Jon Blake (you owe me one). Chris Dilley
took some of the others that were submitted but it's up to the editors what
goes in.
This was part of an on-going effort to publicize these fine aircraft to the
market. BTW, my current CJ is up on Barnstormers for sale. Beat them bushe
s and see any buyers shake out, I say.
Pappy, this one's for you bud.
Craig Payne

Absolutely correct. A water/methanol anti-freeze concoction is still available
for injection into the Pegasus engine used in the AV-8B Harrier for the same
reason.

Just for the record... antifreeze was used extensively in older systems in the
water they would use to inject to increase the air density and thus power. JB

Sorry about your friend. It seems all of us have lost friends to terrible accidents.

Replying to the rest of your message:
No, that is not what the FAA would say. I just got finished asking them.
Craig, I fully believe that you consider your A&P mechanic to be extremely qualified
and knowledgeable and that you feel comfortable following his recommendations.
However, I am pretty knowledgeable too and adding anti-freeze to any pneumatic
system that comes into contact with seals and O-rings (especially those made in
another country) that are essential to safety of flight, is not something I
am going to even consider without extensive and personal investigation into what
exact materials were used in their construction followed by a complete and
thorough testing of what possible impact any additive might make to the complete
system that could impact the safe operation of the aircraft.
I offer that exact advice to every aircraft owner/operator.
Mark

The A&P here has been working on Yaks for over 20 years and currently maintains
4 Yak and my CJ. He also has airline experience as he worked for TWA for many
years. So he just didn't wake up one day and decide it was a good idea. It
is actually a transfer of knowledge from another industry. There are companies
that sell systems to prevent air line icing in cold areas where all sorts of
very high pressure air systems can't freeze up. Most use Methanol - a compound
to not be messed with. Others use the sister product to antifreeze (ethylene
glycol) propylene glycol. Newer "green" antifreeze for the auto industry
use propylene glycol as well. Propylene glycol is in lots of our foods, is what
people vape and is what makes theatrical smoke. So it is very safe.
If we never used different products for different applications we would not have
M-14Ps on CJs (not in the manual), total seal piston rings, fuel injection,
coil over ignition, MSD spark on a couple CJs, bladder fuel tanks, and on and
on.
Fact is A&P has been recommending/using antifreeze in these airplanes for 20+ years
with not issues whatever and there is vast industry use of these chemicals
in very high pressure air lines. Most of the cars manufactured now have aluminum
radiators and some aluminum blocks as well. Most cooling systems have lots
of different rubber components in them and these compounds are safe for them.
If someone has a chevron seal they would like to test for the rest of us
that would be great but the chevron seals in these Yaks he has been maintaining
have been exposed to the stuff for years with the added benefit of rust inhibitors
for the steel tanks and other steel components.
As far as the Feds go....they would say...Experimental....and that is exactly what
the category is for trying things like Corvair engines on airplanes, etc,
etc.
As I said in my original post....YMMV.
Fly safe....an acquaintance of mine died yesterday in his Pitts S2E - clipped trees
on landing. Hell of a guy and a true gentleman.
Craig
