You are "pre moratorium". Enjoy it. Basically your LoL is the same as one for

--> Yak-List message posted by: Gus Fraser <fraseg@comcast.net>
My aircraft is a 96. I use regular pneumatic oil, about 8oz worth which I
drain and replace each annual. I remove the air bottle and drain, then
refill. I religiously drain the snot valve but I also have a cockpit snot
valve control. When I am flying as soon as my popoff valve goes off I open
the snot valve and leave it there. I do this for two reasons:-
1. It reduces the drive pressure on the compressor.
2. It drains any moisture immediately.
A quick check on the air on the way back in then I close it before landing.

You said that you pull an uplock each annual and thus far have had no
corrosion. I wonder how you are able to achieve that? Given that water
WILL get into the system how do you keep parts from getting corroded? Do
you use a special oil?
Best Regards!

Frank,
Thanks for the pictures. What I do is to pull one each annual and
inspect. To date I have no corrosion.

Yaksters;
Here's a link to see how bad corrosion can get in Yak-52 uplocks.
Pictured is the internal, air operated plunger that unlocks the landing
gear. I guess it's cheap insurance to check them often because if yours
are as bad as what is pictured here you may not be able to deploy your
landing gear before too long.

Not enough to make a difference. Remember the work needed to compress the air
in the compressor's cylinder on the up stroke comes back when the pressure
pushes back down on the piston on the down stroke. Total work lost: almost
none. The only losses are friction losses in the compressor itself, a constant,
and the thermal losses due to the cooling fins on the compressor cylinder and
head. (If you take heat out of the system during compression, you will
over-cool the air during the expansion stroke and not get all the work back.
This is the principle upon which an air conditioner works.)
> 2. It drains any moisture immediately.
The popoff valve gets rid of the water vapor once it opens. Once the system is
full there is no flow of air or moisture into the system no matter what the
compressor does. You aren't gaining anything from this either.
> A quick check on the air on the way back in then I close it before landing.
Ah, but this *is* a difference. Now you have increased cockpit workload and
checklist complexity during a high-workload period (approach and landing).

Frank asked what I do. I told him, I am happy with how it works for me. I
tend to apply a very simple rule
"If it works, do it" (waiting for the obvious replies about that statement)
All I can say is that my pneumatic system is like it just came out of the
factory. In fact I had some gear problems this year (it turned out to be a
shuttle ball) and on inspection of my main cylinders they were in great
shape as well.
Physical evidence is worth several buckets of conjecture.

Byron,
My sympathies. For me, I use the canopy rail so it's usually the tab
along the track that I snag my finger on.
On another airplane I owned, I slipped off an iced up wingwalk and got
my ankle snapped between the flap and step. That was the easy part. No
one in the tower was watching so I had to crawl 100 yds on my hands and
knees over snow covered ground, get in my pickup truck and drive home.
But that still wasn't the worst part. The pickup was a manual 4 speed
and with only one foot for gas, clutch and brake I drove home. "perhaps"
some stop signs were blown.
4 months and 2 operations later I could walk without crutches. However,
a cast and crutches could'nt keep me out of the air....but that's
another story.

Someone requested the flap speed for the Yak-52. Per the Yak-52 Flight Manual,
the maximum speed with flaps extended is 170 km/h. If my math is correct, this
is 92 kts.

Last Year Terry Calloway coordinated a huge effort to link everyone flying to SNF
so that we could fly/arrive together...it was a blast to fly together!
So...anyone from the Midwest/west heading towards SNF? I am in Memphis, TN, and
am planning to head to SNF on the 1st of April. Anyone wanting to stop for
the night in Memphis on the way, and join up for the rest of the trip is welcome!
Please drop me a line!
Also, for those attending...it was easiest to "communicate" during the event via
cell phones...perhaps we could start a list so that we could all communicate?

Ladies and gents,
Our UK CAA issues a directive, you can find info at the following links
http://www.yakuk.com/img/piston.jpg up lock piston picture.
http://www.yakuk.com/mpd.htm this link gives the pictures of mandatory AD's
this is the text of the directive. We are please to be of help, regards, www.yakuk.com
MPD: 1998-016 R2
Subject: inspection of up-lock piston assemblies.
applicability: Yakovlev/ Aerostar SA.
Reason: The up-lock piston assembly in both nose wheel and main undercarriage pneumatic
circuits is prone to the accumulation of dirt and moisture which can
cause corrosion. In addition, deterioration in the rubber seals due to lack of
lubrication has been noted. There have been examples where this corrosion has
prevented the up-lock catch releasing, resulting in a wheels up landing. Revision
2 was introduced to exclude the Yak 50 which was included in error.
Compliance: Not later than the next 50 Hour inspection from the effective date
of this MPD, remove the up-lock piston assembly (Yak 52 Parts number, 524705-30)
in both nose wheel and main undercarriage pneumatic circuits. Dismantle and
internally inspect for corrosion in the piston and cylinder. Replace if corrosion
is found. Inspect the seals and replace if necessary. Repeat this inspection
every 200 flying hours or every 3rd to permit flying renewal whichever is
sooner. Rubber parts are to be lubricated with an appropriate rubber grease.
Record compliance with this MPD in the aircraft logbook.
Yaksters;
Here's a link to see how bad corrosion can get in Yak-52 uplocks.
Pictured is the internal, air operated plunger that unlocks the landing
gear. I guess it's cheap insurance to check them often because if yours
are as bad as what is pictured here you may not be able to deploy your
landing gear before too long.

Thanks Bob;
The CJ flight manual does not give a specific flap or gear limit but does
specify a maximum for circuit procedures. Interestingly this is 170 Km/Hr -
the same as the 52 flap limit. Does the 52 Manual list a gear extend limit?
Cheers;
Walt
