You can most likely have it welded and pressure tested for leaks. That may
be easier than trying to find a replacement.
Good luck with it.

Jay;
You may want to consider doing what I did to my main tanks to keep them
from leaking.
Get some fiberglass cloth and some Poly Poxi from spruce. Cut 2" or 3"
strips of glass maybe 4 feet long and wrap your tank in such a way that
the leak is covered with the cloth. Make sure the tank is clean down to
the bare metal before doing it and sand it good to get a rough surface.
Then cover the glass cloth with the epoxy.
Both my main tanks have been going good for over a year without a leak
since I did this.

Sounds like cylinder 5 becoming a bullet. Glad to hear that you are both OK.
I was told once by a Russian mechanic that the best way to test for a hydro
locked cylinder was to measure the top stroke distance of all cylinders
between the cylinder head and the edge of the spark plug hole, if one of the
figures is totally different from the rest there is a problem. I have never
tried this or know anyone that has but I submit it for consideration.
Obviously a total strip down is the best way but this was his quick check.
Dave Sutton had a very similar experience in a Yak 18 but the outcome was a
lot more severe. In that case the cylinder sheared and entered the gear box
on the next bang part of the cycle with predictable results, sounds like the
same here.

Red Star guys
I want you all to know how proud I am of my friend and partner
(owner-partner, not the other kind) George Myers. Our Yak-52 "Stack Doll"
suffered an instant engine failure today enroute to the Rome Ga fly-in.
George made a text book gear-up forced landing in a corn field near
Scottsboro Alabama. The only damage was a small dent in the lower cowl and,
of course, a wasted prop. There was no damage to the airframe anywhere else
(the flaps were up). Tom Kahlert, George's wingman who was on his
shake-down cruise in his own Yak, stayed with him and assisted. Tom said it
was a textbook forced landing. Kudos to George. The failure was
instantaneous. RPM went to zero and the prop shaft broke leaving the prop
windmilling. We'll let you all know what happened when we find out.

Jay,
Over the years I have built many fuel tanks, from J3 to Super cub, Nanchang
CJ6 aux fuel to go- carts. I have to admit that I have never seen a 52
header tank, but if you get your back up against the wall and cannot find a
fix send it to me and I'll see what I can do with it.
Note that I will be in Japan and China Nov 1st--Nov 25th
Always Yakin,
Doug Sapp

The procedure described below is an almost guaranteed way to destroy your
fuel tank by introducing corrosion. By the time the leak shows up the
corrosion will be severe and likely unrepairable.
Why not find and correct the cause of the leak (something chafing on the
tank wall??), correct that and repair the tank properly. It will be a very
small area, probably just a pin hole. The tank must be purged, (vapour
degrease, steam clean, etc.) and repair welded by a competent shop..
Sure this will cost a few bucks but will be a one time fix and your fuel
tank will be as good as new.
With the fibreglass fix mentioned you (or the poor shmuck who bought your
aircraft) will be buying new tanks.

Walt, The old Yak wizard of the not yet frozen north is correct, but like
most old farts he stopped short of "splaining" the whole story--I think it
has something to do with attention span, or the need to get moving to get in
a few more holes of golf before it snows. :o)
First, when you sand alu you remove any corrosion protection from the
surface of the material, you also run the risk of embedding foreign material
in the surface which may (or may not) cause corrosion in the future. Next,
your covering all this raw aluminum with epoxy and god only knows what acids
or salts the epoxy process uses. But the main problem is that once covered
with epoxy you have lost the ability to monitor the condition of the tank
(unless you can see inside with a light). It very easily could be corroding
and sluffing away in small pieces into the fuel system, just waiting for the
day when you pull a few extra G's to completely rupture and spill fuel all
over, or plug your fuel filter. No, this (IMHO)is not a good long term fix,
as a "get me home or ferry to fix" it's ok, but I would suggest that a
proper weld type repair and correct installation is the right fix for the
problem.
Your mileage may vary.
Always Yakin,
Doug Sapp

MAN WHAT AN OPPORTUNITY!
These UN sanctioned police will surly need AIR Support, Reckon, Flak
suppression,
CAP. etc. What better plane to use than a CJ-6 they know what it looks like
i.e.
no Friendly fire incidents. All of you Florida CJ drivers should be offering
your
services to the cause.

| Subject: | Amazing Cloud Activity |
--> Yak-List message posted by: "Frank Haertlein" <yak52driver@earthlink.net>
Yaksters;
A couple, three weeks ago I walked out my door to get something out of
my truck when I witnessed what can only be described as an amazing
series of cloud formations. I live on the eastern edge of the Sierra
Mountains and on this particular day the sky was full of a spectacular
show of lenticular cloud activity. It seemed everywhere I looked there
were multiple lenticular clouds, Sometimes they were stacked one on top
of the other in multiple formations. The entire western sky was filled
with them giving you a view of the invisible air seldom seen. I ran into
the house and got my camera so I could pass this on to my fellow
aviators.
The sight really can't be described and the pictures really don't do
justice to seeing this first hand. None-the-less, I thought I would pass
it on. It really was an amazing sight. Maybe you can get some idea of
what it was like with these pictures. Here's the link

PS Tim Gagnon said, and I quote "We should also have prohibited the
immigration of those nasty Germans, French, English, Poles, Italians,
Spaniards, Russians or whoever else came over on those
boats....wait....who would live here??"
Tim, I never mentioned Germans, Jews, Russians, Spaniards, French,
English, Poles or any other nationality or race....you pinhead. I was
writing about a violent religion and it's adherents known as muslims.
And "YES" I certainly do advocate discrimination against what has been
demonstrated and what is without a doubt a violent religion (cult,
really). The vast majority of the Middle East cheered at the pictures of
the twin towers coming down and you want to tell me not to discriminate
against them? Get lost, buddy!

You mentioned checking for a hydraulic lock by measuring the pistons at
top dead center. I did that exact same thing with my engine. I used a
depth gauge in referenced to the spark plug hole. As I remember, all
measurements were within .010 or thereabouts. After the measurements I
was satisfied there was no problem with bent parts in my engine.

Doug, Walt
I've removed pieces of aluminum re-enforcement that have been embedded
in epoxy laminates for more than 20 years and seen no corrosion. On my
main tanks, I "fixed" cracks that developed around the outside
circumference of the "FACTORY" weld. Obviously, the original welds
didn't hold up against the vibration due to the heat stress of the
aluminum around the weld. Could this factory weld situation cause a
complete rupture when pulling a few extra G's and spill fuel all over?
Well, of course it could. Nothing lasts forever.... even rubber bladder
tanks like we have in some Beech aircraft.
Interesting that airframes have a finite life, engines have to be
rebuilt on occasion, avionics have to be repaired every so often, tires
have to be replaced, brakes wear out, bearings need to be replaced, etc.
The glass repair I mentioned went completely around the tanks and over
the cracks/leaks so that it acted not only as a stop leak but as a minor
structural element in backing up the internal tank rib. My bet is it's
going to outlast me and my lifetime. I guarantee you will go thru 10
engines before I have trouble with my main tanks again.
Some of the best protection for aluminum I know of consists of two part
epoxy primers. Isn't the original Russian zinc chromate primer on our
aircraft a two part epoxy? Isn't it of a similar chemical composition to
the epoxies used for building composite aircraft?
