| Subject: | Views on inlet drains, and oil pumps |
--> Yak-List message posted by: "Jay McIntyre" <jayatnowra@hotmail.com>
For a NZ view on soem of the current issues, here goes...
- From the time we acquired our stock CJ we have had the inlet manifold drains
installed. We did have to weld larger bosses onto the manifold tubes in order
tofit a reasonably sized fitting (1/4" ID rubber hose if memory serves me right).
Never a problem at all and much piece of mind for hydraulic lock.
We do not have a shut-off valve installed and on the4 (!) engines we have had
installed, have never needed one as the oil passed through the exhaust stacks
and drain valve is minimal - even when the aircraft is parked for extended periods.
- One of the other CJ's I look after did decide to spew the tank contents all over
the owners floor. It was obviously the check valve in the pump so we removed
the pump with the intention of cleaning/repairing or whatever was needed. Not
a hope in hell as the valve body is swaged into the pump body - trying to remove
it would only damge both beyond repair. Muc
h simpler to replace the pump. Having said that the system was very cunning with
passageways all over the place.
- Lastly, for convenience at this time, we have plumbed our snot bottle into the
intake drain line. At flight completion, open the quick release valve and then
drain the snot bottle - no more covering yourself in goop!

| Subject: | Manufactures and Overhauls |
--> Yak-List message posted by: "Richard Goode" <richard.goode@russianaeros.com>
Yak Club Mailing List
Manufactures and Overhauls
There is probably more misinformation on this topic than any other. Much of this
is propagated by those with an interest in claiming that they are or that they
represent the "only authorised" overhauler / manufacturer etc. The main points
however are:
Aircraft
a.. Under the Soviet system, a Design Bureau designed and a totally separate
factory manufactured. This is true of aircraft and engines.
b.. There was therefore no Yak manufacturing unit, and the five principal types
of Yak light aircraft (18T / 50 / 52 /54 / 55's were all built in different
factories, within indeed only the 50 and 55 being built at the same factory (Arcenyiev
in the Russian Far East).
c.. Since all Soviet aircraft were operated to military schedules, this involved
frequent total overhauls, and in consequence a number of organisations through
out the former Soviet Union and its satalites were authorised to perform
overhauls of airframes and engines.
d.. With the collapse of the Soviet Union and a lack of central government funds,
both manufacturing units and overhaul factories have since been forced to
find business rather than wait for it to come!
e.. In addition various entrepreneurs have set up their own overhaul facilities
in Russia and other countries such as Lithuania.
f.. In terms of authorisations, of the original major overhaul facilities, I
suspect that only Shakhty and Vinnytsya in the Ukraine are able to do significant
amounts of work.
g.. Having said that the aircraft are not that complicated and other factories,
apart from the original "authorised factories" are doing very good work. For
example the Smolensk factory, the original manufacturer of the Yak-18T (and
indeed still producing the original 18T in very small numbers, and now the new
turbine SM-2000 version), overhauls various Yak aircraft as well as the 18T,
to a high standard.
h.. In addition the Yakovlev Design Bureau organises overhauls through its own
facilities.
i.. A further complication arises because some of the recent organisations might
well have approvals from their local Civil Aviation Authority, but not necessarily
have it from the aircraft or engine manufacturer.
j.. Inevitably the manufacturers feel that they have the ultimate right to authorise
overhauls, and try to keep a strong involvement to control the market,
although with only limited success.
k.. In terms of the Yak-55, it is of course still in production as the Sp-55M,
and in theory the Arcenyiev factory could produce brand new 55's, or certainly
overhaul existing ones to new standard if required.
Engines
a.. The M14P series was designed by the Vedeneyev Design Bureau (OKBM), and then
manufactured by the Voronezh Machine Manufacturing Plant in the same city.
b.. Following the collapse of the Soviet Union OKBM has gone into manufacture
of engines, albeit largely from unused but old stock engines, of which there
has been a reasonable stock. This has included the development of new engines
- the 400hp M14PF and the 450hp M14R.
c.. Separately the Machine Plant has continued to make very small quantities
of totally new engines, and has more recently developed the 420hp M9F.
d.. Aeromotors in Romania, which was originally licensed to produce engines for
the Yak-52 made by it's associated Company, Aerostar continues to make engines,
although I do not know how long their supplies of components will last.
e.. A distorting factor in the engine market has been the numbers of old, but
unused engines available, but the supply is definitely coming to an end, particularly
with the large numbers of home-builds (Pitts Model 12 / Murphy Moose
etc) that are utilising the engines.
f.. When engine supplies do run out, I have no doubt that prices will rise significantly,
and that of course will mean that it will be worth while for the
factories to manufacture engines totally from scratch.
g.. For engine overhauls, clearly these are done by a variety of organisations,
in a similar way to aircraft. However supplies of components are becoming more
difficult to obtain. As with airframes, there is with engines, the same questions
of "authorisation", but in the final analysis the engine is not that difficult
that, given a supply of components, competent engine shops in different
places can overhaul them. However it is a reasonable assumption that only properly
equipped shops with formal authorisation and proper engine test beds etc
can make correct work of overhauls. In addition there is no doubt a large number
of "paper" overhauls - i.e. new paint and new paperwork only were done,
and obviously a number of these engines are still in circulation, or indeed being
used today.

After 8 years of living with different out-of-balance Chinese nose tires
&
wheels, we finally converted to the Cleveland nose wheel. If you
haven't done
it already, you should definitely consider it. The new unit is so
smooth, the
only problem you will experience during the transition is believing the
nose
gear is really down when you land!
Doug Sapp now has a new conversion kit that does not require axle
adapters &

To Al and all,
I should clarify my opinion of southern culture, for I just spent ten years
of my life in "LA"
Lower Alabama that is...
Just East of Mobile, near Pensacola....still own my home there, come to
think of it, I'm still a card carrying citizen of them parts...
And I do here declare, I speak fondly, and often, of the warm gulf waters,
warmer lakes, all the snakes, oysters on the half shell, and those fine
women only a yankee would call a bell...
I might just even move back -
So my apologies to my neighbors on the crack about the mythology of the gun
rack...
At least there the only thing getting dead is often a seasonal buck
For I live in silican breasted, BMW ownen, martini sippin, drive by shootin
western "LA" now,
and I still drive only a truck...

Actually, unlike the oil shutoff which can trash your engine if it fails, a failure
of an intake drain tube is not likely to cause any real problems. When you
need full power the positive pressure from the supercharger ensures that the
cylinders receive full rich mixture in spite of the leak. There will be almost
no power loss. When you pull the throttle back so that the manifold pressure
is below ambient, the mixture in the cylinder with the leak will start to
run lean and you might get some rough running but it will smooth out again when
you advance the throttle.
So, to my way of thinking, installing quick drains in the intake risers for the
lower cylinders on a Huosai J1A is a non-critical mod that will "fail safe".

My first encounter with the railbirds at West Texas Airport was attending an
EAA meeting there where they served Doughnuts and Beer. That was quickly
followed by firing up a Jet Provost out front and roasting marshmallows in
the tailpipe. At that point I knew, "these are guys guys". It was as if
somebody had left a bunch of 13-year-olds at the airport with nothing to do.
I knew it was the airport for me.

I agree with Brian. I have flown my airplane (CJ-6 with M14P) with the
intake valve open twice in 4 years (can you say preflight). There was
absolutely no discernable difference in the way the engine felt or sounded.

Many mods are well thought out and when installed properly with the correct
material and good judgment perform well. Trying to save a buck by
shortcutting good sound principals, will get you in trouble every time.
This is the case with the intake tube problems that I have seen. By using
rigid tubing you can save about 50 bucks on the installation cost, but in
time the vibrating rigid tubing it will crack the intake tubes. IMHO the
intake drain is a great idea, installed properly by someone with the right
tools and skills it will do the job and last a long time.
Always Yakin,

Hi, Doug did you get my last note on the engine mounts and who I was getting
them off.
Also in the great debate regarding this drain do you have a kit for this
modification
it sounds like if some one produced comprehensive kit it would sell rater
well.
