A question I should have asked, another reason to have the detector
available for spot checks, or perhaps a Perm. installation. One has no way
of detecting just when the failure occures. An internal visual can be done
by use of a light and mirror I suppose. This should expose anything but a
crack. This of course would open as the exhaust expands from heat.

Hi ,
I need TO-1000 form, AD's, and service bulletins for my YK18T. Because it is
the unique yak18 plane flying in Turkey maintenance is really torture to
me.Also I must get information about the time of overhaul procedures in
future. (I tried to contact to Rob Kent but still couldnt get answer)
Thank you very much for your help.

Mozam,
Is it possible to scavenge warm air from the top of the inspection plate on
your oil cooler. The 50 does not have a heat shroud on its 2nd section of
the exhaust on the right bank. It gets so warm inside the pit of the 50
since there is an opening at the top of my oil cooler that I had to install
an insulation blanket on the top of the cooler. It did not seem to make much
difference in the amount of CO getting into the nose by doing that though.
My cooler is mounted farther forward than the ones on the TW. My exhaust
vents parallel to the cooler not in front of the cooler like the TW's. Tim
Williams installed fins on his cooler to vent the hot exhaust away from the
cooler as I remember.
I suppose exhaust stack extensions could solve the problem too.
Anyway, if you could capture the heat off the cooler then you would not have
to reinstall the shroud.
Install a Scuba system with a stage I - II regulator connected to mil spec
O2 hose that terminates on a CRU-60 for fresh none pollute air with CO. Then
you could hook up and use that old MBU-12 Aviator's Mask you have lying
around from your glory days. Of course, you would have to get a pre-amp for
your Mil spec mic. Know where to acquire that too.
Then you do not need to worry about the concentration of CO in your pit. It
is absorbed by inhalation not by osmosis (skin contact). The problem is
having to refill or swap the tank at the end of a couple of sorties. You do
not need to breath the compressed air once airborne so you can get a couple
of sorties out of a 3500 psi fill. Or you can invest in two stage I's and
make a refill manifold. Then you could refill the tank without removing it
from the A/C.
One could also invest in a diluter demand regulator and install a LOX tank.
Problem there is the expense and the fact that you would need to maintain a
closed circuit so you would have to breath 100% O2 continuously during
start, taxi, TO, hi Alpha maneuvers, landing, taxi in, run-up and shutdown.
Otherwise drop the mask or loosen it to the end clip on the bayonet and
breath around it.
Now there is nothing wrong with breathing 100% O2 for an hour or so except
you have to remember to clear your ears frequently after such a flight to
altitude otherwise you could awaken the next morning with an ear ache from a
serous otitis.
Just a thought fresh air vs LOX and CO inhalation from TU heating shrouds.

Doc,
My O2 mask wearing days are over. If I have to get a mask to fly my Yak, it's
gone. [Wink]
I only need heat in the dead of winter while cruising at altitude and the standard
-52 system works just fine for that. I don't want to engineer a whole new
system to replace one that works fine.
However, like many other systems in our planes it must be inspected to insure it
is working properly...lest it bite you. And inspecting this section of exhaust
can only be done by removing it and looking closely for any cracks inside
the inner most pipe.
I suspect my -52 isn't the only one that has not had such an inspection done in
a while...if ever. I also suspect there are other -52's out there right now
with cracked pipes that are pumping CO into the cockpit. What are the odds that
only one -52 in the world (mine) had an exhaust crack in that section of pipe?
Fly safe,
Steve

Mozam,
Copy. Seeing how you seem to love your YAK as much I love mine I don't think you'll
be parting with her anytime soon.
They'll be prying my stick from my cold hand!
How old was you exhaust system. Mine is 5 years old. We had it off 2 years ago
to change an engine. It still looks new especially since I'm putting about 35
hours on her a year now. (Flying the 50 much more than the 52 is why).
Check with Steve Culp @ 318-222-0850. If that does not work let me know, I have
another number for him too. Last I knew he still had some exhaust parts/ spare
sections for the 52.
Wonder how the Trantula System on TJ's 50 is holding up. Understand the tuned pipe
system for the CJ was not hacking it. Something about a harmonic in the pipes
causing them to crack and break. One of the CJ's at Alabaster in Birmingham,
Al had that system with the problem of the stacks cracking and breaking. One
broke in flight. Lucky. No fire.
And off thought. Not getting to fly today secondary to some slow moving bitch named
FAY. Why do they always start with the Tornado warnings at 02:00?
Doc

Doc,
My exhaust is original, installed at factory in 2001. It has about 600 hours on
it.
Keep in mind, you cannot see the cracks/holes in this section of exhaust while
installed on the plane. On the outside it looked like new...but the inside was
totally rotted out! Be careful out there.

The 52 does not have a water filter as the CJ does. It only has a very
small air filter. Some people have installed Doug's SS filter. But not
many.

Given the symilarities between the CJ and the Yak 52 has anyone
formed an opinion on whether the water filter is worth having? Should I
add one to my 52? The 52 seems OK without one so maybe they are not
needed in the CJ.
