Check the tightness on the gland nuts on your intake tubes. Especially
at the base going into the ( coming out of) the supercharger. Check the
tightness on your manifold pressure lines at the firewall and the top of
the supercharger. How old is that hose.
Have you calibrated your gauge? Is the RCP gauge reading the same?

I=99m positive that in the past, it would go to 800 and I would
back it down to 700 during climb out.
Yesterday, during a XC, I was seemingly limited to 660and was

Looks like the majority of the lineup has a good story to tell. If you
want to draw more favor, tell a compelling story. Where's the war footage
and stories of Red Star aircraft? Let's get that easily accessible. I'd
love to help with a coordinated PR campaign to help those of us that
operate eastern block aircraft tell the story.
Do a better job with signage where the aircraft are displayed (again,
telling the story).
The guys who operate american iron are more relatable because the story is
in our history books, on TV, movies, etc. Tough to compete with it.
The sheep want to 'feel' something.

Cory this is the check valve setup for the pop off valve assembly for my YAK
50. Takes a little patience but the old YAK check valves can be removed fro
m the pop off valve to rebuild the system. Since the pictures are on my iPad
I will send them as singletons. Doug has a pop off valve manifold that will
work also. You just have to mix and match. The metric male and female fitti
ngs are the same. The guts are not interchangable.

No argument. The decision on what to do is up to each of us. Having
everything in a neatly arranged binder is professional and is the right
thing to do.
That said, I am not going to go beyond what the regulations require of
me to show to the FAA. Neatly arranged sure. In a binder, heck yes!
But copying every possible thing out of logbooks just in case they
decide to ask, no.
You can, I won't... no more to it than that.

It is not incumbent on you to anticipate those needs and have copies in

"Certified Copies" although that is never a bad idea, especially when
and if you want to cover your own six when sending them in.

I have taken the spring and piston out of the CJ6 pressure relief valves
sold to me by Doug Sapp and have installed them into my original YAK-50
pressure relief assembly twice.
My aircraft is currently flying in that condition. With a CJ6 piston
and spring installed.
There may be different CJ6 parts out there that I am unfamiliar with, or
there may be different YAK parts that I am unfamiliar with.
However, on my personally owned YAK-50, and the second YAK-50 I have for
parts, the parts that Doug sold me worked perfectly.
Not sure what you ran into where it did not work, and I trust you when
you say it did not work for you..... but it worked for me because I am
not talking theory here, I've done it on my YAK-50, I've also done it on
a Sukhoi 26 and also on a Sukhoi 31.

Unfortunately, the CJ6's pressure relief valve or pop off valve's
internal components are not the same as the one on the 52. The pistons
are not interchangeable.
If you need a new piston for a Yak 52 pop off valve, I believe Jill has
them and so does Cliff Coy at Border Air. The spring for the 52's pop
off valve may be a little harder to find. But Jill or Cliff can help
with that.
We have converted a few Yak 52's to the CJ6 pop off valve assembly with
the two Chinese check valves because the Chinese check valves are
significantly less expensive and Doug typically has them or overhaul
kits in stock. (Thank you Doug). The Russian check valves are VERY
expensive, IF you can find them.

The YAK-52 uses different air components than the YAK-50. The one way
check valves are different than what is used on my 50.
Amazingly enough, there were also two types of one way check valves used
on the 50. I've got both types in my hangar.
The Coy's can rebuild those one way check valves by the way, and they
did mine... which worked perfectly every since.
Yes, I should have been more definitive... sorry Dennis. I was speaking
of a YAK-50.

Being parked against the back fence (called the "North Forty") has its
advantages.
One; you're closer to the WB camping area accept for the "L" birds (who get
no respect at all).
Two. You are the closest to the gate entrance we normally come in. The
T-6 guys are parked just one role ahead of us. (BTW all the Mustangs are
parks just 150 yard away on the grass also).
Three, When doing local flying we have the easiest in and out of tie-down
of ANY of the WBs.
Four, we are the ones who usually flying the longest in the show. (First
airborne last to land.)
I didn't know until just now that we will be featured in the WB form this
year. It maybe that last day and the last program, but Sunday is a big
crowd day and look who we share that form. I know Connie who sets that up
just don't let any old WB group in there. There is limited time and space in
that program. Airplanes and people are moved into and out of the
presentation area. Its not a static place. One big problem is most WB groups
(particularly RPA ) leave on Friday or Saturday. And WB participation (again
particularly RPA) is sparse at best.
I've been going to OSH for over 17 years with my CJ. The group that
welcomed us the most was the "L" bird guys and quite frankly championed our
group. Its took years to get a spot for our tent "along the fence" and the
powers that be at OSH accept us as part and parcel of the show. They show
concern when we don't fly. They want us to have a good time. And except for
a few paid staff, just about everyone there is and has been a volunteer for
years.
America is always going to be "pro-American airplanes". Blame that on
Hollywood. But Americans have always loved and respected the "underdog". So
be the proud American Underdog. We won the cold war and these airplanes
are the booty of that win. Believe me if you were in Lulabulastan with your
AT-6 you'd be an underdog there.

| Subject: | Air system 'stuff' |
I own a 74 Yak-50 and an 84 Yak-50.
The one way check valves between both aircraft are much different. The two pressure
relief valves are identical on both models.
Let me explain the process with a tad more detail as you might have missed it.
In my 50 Doc, I could not just replace the piston. I had to replace the piston,
the spring AND THE TOP SCREW ON PIECE. If you just try to replace the piston,
it will not work.
The only part of the pressure relief part that is identical is the seat, and the
thread. The top parts all have to be replaced.
Did you try that?

Speaking for the 78 model 50, the internal components are not the same YAK vs the
CJ. It is easy to swap the entire check valve assembly out though. That is
what I did on the 50. Solved the leaking check valve at the pop off problem in
about 4 hours. Just wish I had caught the airline leak at the manifold for the
acutators before the gear collapsed. Would have saved a lot of headaches!

If I was not clear before, I apologize. First, I am not speaking for YAK-52's....
Dennis tells me they are different than the 50 and I believe him. He is the
52 GURU~!
2nd, I took the screw on top piece, the piston, the spring, off the CJ6 pressure
relief valve, and screwed them ALL down onto the original YAK-50 pressure relief
assembly that remained installed in the aircraft.
Cory, you are dead on about can you replace this thing with a western made product.
Yes, and there are some very good ones. You need to adapt the metric line
fittings to AN, or just cut the Russian pipe, put an AN nut on it, and reflare
it. Can be done.
The adjustable pressure relief valve I saw cost $600+ new. So I stayed with what
came with the airplane.

Doc, you said that you wished you had caught the airline leak at the manifold for
the actuators before the landing gear collapsed.
I'm kind of confused by that statement, and it brings up an important point. The
YAK-52 (I say again YAK-52!!) uses an internal ball lock assembly internal
to the actuators. If those are in bad shape and you lose pressure to the landing
gear ..... the gear can collapse. I've seen it happen three times on one
YA-52 before the owner finally got the actuators repaired.
However, the YAK-50 (I say again YAK-50) does not work like that. It uses an EXTERNAL
LOCKING device that is purely mechanical in nature. Once the landing
gear comes down, you can remove all pressure from the pneumatic system and land
safely with no possibility of the gear collapsing. In fact that is a good safety
procedure for every YAK-50 owner to know, which is why I am writing this.
If you can get the gear down on a YAK-50 that has an internal air leak, you
can then place the gear handle back into the MIDDLE position, which isolates
pneumatic pressure from the landing gear system, and allows the engine air compressor
to pump back up to 50 atmos on BOTH the main and emergency bottle. This
then allows you to land with full pressure available to the BRAKES! I flew
a YAK-50 almost all the way from the east coast to Ramona California that way
(for Vladimir Yastremski). It had a bad air leak when the gear went down, enough
so that I would have had to land with no brakes available. This method is
not documented, but trust me when I say I am 100% sure of how this works. It
could be considered an Emergency Procedure.
Moving on, I would assume that during every Conditional Inspection on your aircraft,
you swing the gear. Part of that inspection is to make sure that the landing
gear lights do not show down and locked BEFORE the landing gear is actually
DOWN AND LOCKED! I.E. You don't want to have the gear lights indicate it
is down, when it is actually NOT down. This requires the landing gear to be
lowered very slowly with a steady hand on the master air valve, while one person
watches the lights and another person watches the external locking block snap
into place.
So assuming that your landing gear indication switches were properly adjusted,
then any kind of airline leak ANYWHERE in the system would not cause the gear
to collapse once it indicated down and locked.
What this means is that if your gear collapsed upon or after landing, then they
were never down and locked to begin with and you probably missed the fact that
both green lights were not lit, or you heard what you thought were normal sounds
and assumed the gear was down. It's an easy mistake to make, and I personally
believe I made the same mistake myself!
An air leak can cause enough pressure loss to keep the gear from coming down and
locking... but if that were the case, there would be no air left in the main
and emergency bottle, because you would have blown the gear with the emergency
valve.
But if the gear was down and locked and indicating same ... you only have two possibilities.
1. The landing gear indicators were totally mis-rigged *AND* you had an air leak
preventing total gear extension, in which case you should shoot your A&P mechanic
for not inspecting the landing gear switches properly.
2. The landing gear was never down and locked to begin with.
Once the gear is down and locked, it does not need air to keep it down and locked.
Just the way it works Doc, so you may need to rethink what happened.

On my next YAK 50 rebuild I'm going to rely heavily on Aircraft Spruces' metric

Being parked against the back fence (called the "North Forty") has its

both the RU and the CJ check valves have arrows on them to indicate the direction
of air flow through the check valve. You need to replicate that direction when
swapping out the 'cJ check valves or you will either over pressure the compressor
if the error is on the check valve from the compressor.

Don't know Mark. To use a famous quote, " It just went blew!" Is the 74 the same
as the 78 as the 80 as the 85? No. The gear is beefier on the 85 than the 78
for one. My mechanical lock spring is not as hefty as the 85's either. The fuel
system is different also. I know that from crawling around on the 85 sitting
in the back of my hanger. The 85 has better lateral stability than than the
78 slick wing that I have...had.
The 78's actuator as you say does not have the ball check valve. It uses air to
push and pull applied at either end of the actuator. As I said my spring is smaller
than that on the 85. And all I can tell for a heart beat there I saw a
wind screen full of green as the nose went down. One blade is shorter than the
other as well as it sheered off just inside the cowl diameter and I have dirt
up in my hub.
The CJ nose strut actuator will work on the 78 is another difference. The CJ actuator
is the same as the YAK 18A's. I don't know if they will work on the later
model 50's.
One of my air lines has 04 on it and the other has 02 on it. The lines to the actuators
have faded enough that I can not read them. So again this was my error
in not replacing them sooner.
I can tell you all incidents or accidents start as a series of small events that
lead up the big event. Just need to break the cycle to prevent the incident.
I did not catch the series. If I had listened to that little internal voice that
said taxi into your ramp and shut down as I taxied by after fueling up we
would not be having this conversation. If I had not been pressed to beat a TFR,
we would not be having this conversation. If I had not checked the main air
valve before TO, we would not be having this conversation. If weather had not
become a factor in route going from marginal VFR to IFR resulting in my turning
back, we would not be having this conversation. But then again had I landed
on concrete instead of grass I may not have been here any longer and we would
not be having this conversation for sure. If I had squeezed the brake handle
and release it before turning the air on to start after priming we would not
be having this conversation.

The YAK-52 (I say again YAK-52!!) uses an internal ball lock assembly internal
to the actuators. If those are in bad shape and you lose pressure to the landing
gear ..... the gear can collapse. I've seen it happen three times on one
YA-52 before the owner finally got the actuators repaired.

> However, the YAK-50 (I say again YAK-50) does not work like that. It uses an
EXTERNAL LOCKING device that is purely mechanical in nature. Once the landing
gear comes down, you can remove all pressure from the pneumatic system and land
safely with no possibility of the gear collapsing. In fact that is a good
safety procedure for every YAK-50 owner to know, which is why I am writing this.
If you can get the gear down on a YAK-50 that has an internal air leak, you
can then place the gear handle back into the MIDDLE position, which isolates
pneumatic pressure from the landing gear system, and allows the engine air compressor
to pump back up to 50 atmos on BOTH the main and emergency bottle.
This then allows you to land with full pressure available to the BRAKES! I flew
a YAK-50 almost all the way from the east coast to Ramona California that way
(for Vladimir Yastremski). It had a bad air leak when the gear went down,
enough so that I would have had to land with no brakes!

sure of how this works. It could be considered an Emergency Procedure.

> Moving on, I would assume that during every Conditional Inspection on your aircraft,
you swing the gear. Part of that inspection is to make sure that the
landing gear lights do not show down and locked BEFORE the landing gear is actually
DOWN AND LOCKED! I.E. You don't want to have the gear lights indicate
it is down, when it is actually NOT down. This requires the landing gear to be
lowered very slowly with a steady hand on the master air valve, while one person
watches the lights and another person watches the external locking block
snap into place.

were never down and locked to begin with and you probably missed the fact that
both green lights were not lit, or you heard what you thought were normal
sounds and assumed the gear was down. It's an easy mistake to make, and I personally
believe I made the same mistake myself!

Just the way it works Doc, so you may need to rethink what happened.

No my problem was not in the pop off valve itself. It was in the check valves.
You are correct the top part of the CJ pop off valve with the piston and spring
will work on the 50's base. just have to adjust the pop pressure afterward.
The CJ T fitting is a male fitting at the base of the pop off valve.
