Dear Kevin
Yak/Sukhoi Oil Tank
It is not of course a flop tube - it is a much more efficient rotating pick-up.
However the potential problem is that over a period of time the bearings can
seize, so that it simply doesn't pick-up at all attitudes, which is relatively
common with older aircraft.
Not a huge job to disassemble and clean/replace bearings.
Best regards

Folks,
If you live in the Southern Calif region, on Sunday Dec 7th, the anniversary of
the Raid on Pearl Harbor, the "Killed In Action" fund and Department of Defense
have a special event at Palm Springs airport between 10-12noon. The DoD is
picking up a painted 25 ft mural displaying the heroic actions of our troops
in the war on terror to be displayed at the Pentagon. I'm told several high ranking
govt and DoD dignataries will be present along with the media.
The KIA Fund is working with the RPA to set up a voluntary nationwide missing man
formation program to support the funeral services of veterans from WWII to
Iraq/Afganistan, they have requested a fly-over of this event.
If anyone would like to attend this event on behalf of the RPA and/or perform a
simple flyover in formation
please contact me off list, or Barry Hancock. This will not be waivered airspace.
Thank you,
Drew Blahnick
The RPA

I just got an envelope in the mail from Eaglet Aero Technology in China
describing the "Eaglet" CJ-6G along with parts and modifications.
I think many of the photos in the marketing brochure were in fact of
existing US airplanes sporting Yakity Yak paint jobs with some creative
Photoshop touch-up removing N-numbers and pilot's faces. There were listed
mods for wing tanks, drop tanks, adjustable seats and 400hp variant.
Of course, no pricing or other order information was present (pangs similar
to Russian posts for parts without prices or logistics we've seen the past).
Is it me or would most potential customers in the west be looking for the
bottom line in all this? What's the bottom line on this outfit?
Jim

| Subject: | Yak 50 tail wheel shimmy |
--> Yak-List message posted by: "Dean Courtney" <deancourtney696@hotmail.com>
Yakers,
You may remember a post a while back where I warned not to leave your YAK
50's tailwheel turned around backwards, as if the tail oleo went flat with
the tail wheel in that position that it would cause sheet metal damage
inside the fuse. FORGET THAT.
If your tail wheel oleo is rigged correctly it is not possible. Oleo
inflated, or flat.
In our case the adjustable rod end, at the tip of the oleo piston (point
where the oleo bolts to the top of the tailwheel) was completely bottomed
(misrigged) in the piston rod. This allows too short of a center to center
with the oleo fully inflated. This lack of length will allow the
tailwheel-to-oleo angle to "reverse" when you push the airplane backward.
Instead of the "uphill" angle they should maintain, they go "downhill". Not
a problem if you never push your airplane backwards. When you do, and If
your tail wheel is missrigged, the "springyness" that you assume is the
oleo, is really the sheet metal inside your tail yielding to the top of the
tail wheel assembally!! Quick operational check. With your tail oleo fully
inflated. Push your airplane backward so the tail wheel yoke/tire have to
reverse. The portion of the upper tail wheel assembally that is protruding
from the hole in the bottom of your airplane, SHOULD BE vertical, or
slightly aft. If it is slanting forward toward the tailwheel lock. Adjust
the rod end screwed in to the tip of the oleo piston shaft. To confirm, you
may kick the tail wheel yoke/tire leading edge (while reversed, ie kicking
toward the firewall) and see that it stays vertical, and seems to be against
a hard mechanical stop. As long as it is vertical, and will not move forward
of that. it is adjusted correctly
NOW ON TO TAIL WHEEL SHIMMY.
Seeing as how I have the entire tail wheel out on the bench. Including the
casting formerally riveted to the belly skin. Let me tell you what I have
found. As you may have noticed, Russian hardware is not plated in any way to
prevent corrosion. Thus if you do not lubricate EVERYTHING that moves on
these airplanes the bolts WILL freeze to what ever they are in contact with.
How severe can this be? Bolt freezes to bearing inner race, ball/sphere
bearing freezes to race, race then has to move so it spins in it's "press
fit" seat. Steel race-vs-rare/expensive aluminum part it was pressed into?
Steel wins. You loose. DO NOT BE TO LAZY TO SPRAY-AND HOPEFULLY SOAK-WD40
(at a minimum) ONTO EVERYTHING THAT MOVES ON THESE AIRPLANES!!!
How dose this lead to tail wheel shimmy? Remember your tail wheel hinges aft
to relieve shock. At that hinge point you have a single bolt, running
through the tailwheel mount (riveted to fuse) then through the tailwheel
upper assembly itself. Within the upper tail wheel assembly, that bolt runs
inside a larger diameter sleeve/axle. All of this rides in bushings. When
was the last time you dropped your tailwheel assembly out and
inspected/lubed those bushings?? If you know your tail wheel lock is tight,
but you still get shimmy. Think about those bushings. That is the next
source of looseness in the system, after that look at the rivets mounting
the tailwheel to the belly skin. Even if you do not have tail wheel shimmy
you SHOULD pull that one mounting bolt out and lube it. Remember the
sleeve/axle inside the upper tail wheel that the bolt runs through? It is
plain steel, as is the bolt. They WILL fuse to each other with the strength
of a welded joint. Save your self a TON of work, just lube the damn thing!!!
Just because it does not have a grease fitting DOES NOT mean it does not
need lubrication!!!
There are 40 plus CRITICAL areas needing lube at inspection on a Yak 50.
These are IN ADDITION to anything that has a grease fitting!!! Interesting
that about half these points are common with the Yak 52, but they saw fit to
give it grease fittings. Remember the Yak 50 was disposable, if you would
rather not dispose of your machine then MAINTAIN IT. If it moves (even a
little) it NEEDS some form of lubrication!!
Cheers,
Dean Courtney

LPS 2 spray lube has more longevity and does not tend to dry out as much as
WD40 does. WD40 is good, but LPS 2 is better. FWIW

Also FWIW, in general terms...
For many lubrication jobs where I have previously have used WD40 (Q20) here
in SA, I use motorcycle chain lube. The one designed for o-ring chains that
will not harm rubber seals - it sprays on thin and will wick into confined
spaces, then after some time dries out but leaves a thick lubricating layer
on that will not run off or blow off or dry out further. If it works for
chains on high performance motorcycles, it should work in a number of other
places on aircraft.
Just my 0.02 worth - after the dinner & wine I have just consumed, it may be
worth even less.

I would like to add my two cents (Yuan) to Blitz's comments, No I won't be
dealing in any manner with these folks. "once bitten twice shy" is the old
saying, and I think it applies well here. I do think that my stainless
steel exhaust photographed well don't you?? These guys are amazing!
Professional? honest? and efficient? Well I won't comment on the first
two on the list but if efficiency is taking a full calendar year to ship the
correct part after shipping the wrong parts and then making me pay for the
shipping of the correct part is efficient then I must be in the wrong
business.
If you want a new CJ let me know, we can get the job done.
Always yakin,
Doug Sapp

LPS 2 spray lube has more longevity and does not tend to dry out as much as
WD40 does. WD40 is good, but LPS 2 is better. FWIW

Yakers,
Wd40, chain lube, LPS 2, engine oil, lub-ra-plate. All excellent products.
The biggest point I would like to make is that they do no good while still
in the can. Give your moving parts a drink!
Both for lubrication, and for corrosion control.
Most of the major head aches/re-machining/re-manufacturing of parts we have
had to due to our Yak 50 are due to seized bearings. Those little Nickel
sized guys in your rudder horn, are the same ones at each end of the landing
gear rams on a Yak 50. Russians use all roller bearings in protected areas
(cockpit-flight controls/rudder bar) and selected spherical bearings in
exposed applications like the landing gear actuator ends, contol cable to
control surface horn, ect.
Here's the order of destruction:
Steel bolt in steel bearing- with no protective coating of oil or cad
plating on either.
Bolt fuses to bearing inner race
Bolt has to spin in its mount, galling what its mounted through and placing
dangerous wear on the bolt.
Bare steel bearing fuses to bare steel bearing race. Movement still has to
occur, so the force breaks the interference/press fit of the race to the
aluminum part. Steel eats aluminuim.
Would you rather lube the bearings, or replace the forged aluminum parts in
your landing gear?
In our 50. A frozen bearing caused a fatigue failure of the clevis that
connects the landing gear to the landing gear actuator/ram. If the bearing
can't move, something else will take the stress/wear. Do you know the part
number/availability/cost/stocking supplier of Yak 50 landing gear clevis's?
It's called pull both landing gear to remove the remaining good one, find a
quaility machinist to duplicate them from raw materials, then......$$$ Lack
of BASIC maintenance. Lubricating moving parts. After a few trips to you
favorite machinist, you become a fanatic about lubing this SH#$@%!
Remember, your US maintenance provider may be lax on this due to the fact
our AN hardware is plated. It can withstand SOME lack of attention without
seizing. Unplated Russian parts cannot. Airframe overhauls every 5 years in
the motherland averted this. A little attention to detail every 12 months
here will do as much or more.
Cheers,
Dean

I always enjoyed just using "Experimental" and then my N # when identifying
myself to ATC for flight following in the Jet. After a few minutes, they
avariably come back and say "What type of plane are you?" after they monitor
my speed on Radar. I then reply "an L-29" they then comeback and say, "Yea
but What kind of plane are you" :)
