Frank,
In many cases you can use US hoses and US fittings if you use the metric nut
off the old fitting on a US fitting instead of the US nut on the US fitting.
However, the hoses are slightly different (wall thickness, stiffness etc)
and so are the fittings (US fittings are often longer). In some cases
because of bend radii etc, they can be difficult to fit properly. One
advantage of the US hoses and fittings is you'll know they are new and of
course are available anywhere.

Yaksters,
I'm replacing my fuel and oil hoses. OK, so now I have them out of the
airplane and disassembled. Problem is I'm not sure of the hose sizes to use.
I'm thinking Aeroquip 303 hose might work but not sure of the correct sizing
given the metric end fittings. Anyone got suggestions on the correct size of
the hoses? I'm replacing all the hoses so I would need suggestions for all
the different sizes.
Thanks in advance

Marks, George, Bill, Doug, Colin, Joe et al,
One of my many frustrations with Aerostar from the days when I was one of
their dealers was the difficulty (i.e., impossibility) of getting parts or
data from them. The factory was invariably unresponsive, parts and data
were unavailable, prices unknown, shipment date god knows when etc. Mostly
they expressed amazement in my interest in such things--i.e., why wouldn't I
just ship the airplanes to them for maintenance and repair? I hope this has
been rectified. I'm sure many of us would welcome their active support and
would reciprocate.
MJ--Thanks for calling attention to your web site's excellent pictures etc
of what we would call Service Bulletins and Airworthiness Directives. As
I'm sure you're well aware there is continuing confusion because of lack of
information. The factory would never provide me with anything more than a
bulletin list--no text, parts or dwgs--making compliance impossible. Can
you provide full text etc? Your compliance calculator is pretty clever.
Does anyone have comparable data for CJ's? Eaglet? Not to question any of
your estimable services, but if you get hit by a truck we're all gonna be up
the creek--it would be nice if there was a hint of a semblance of factory
data and support. This list is a poor substitute (helpful as it is). Help!

Dennis, you don't need to "find" these parts, just order them from the
factory they are in current production. OK it takes 60 days but then again
Cessna take 6 months or more.
If Aerostar is supported with orders they will stay in business to the
benefit of all, I strongly support and recommend that all dealers use the
OEM for this reason.
Some parts you will not be able to "fix" and have to purchase, if the OEM is
out of business then you really are stuck.
Cheers, MJ

But these designs seam to forget the access to the "danger area" of the 2
lightening holes where the trim cable passes through. This HAS BEEN KNOW to
allow a fuel drain screwdriver to get to the crank arm. also with respect
the design that's been offered for sale will let pens and coins through so
is it worth it. Both those items mentioned will jam a crank arm, espec a
steel pen as has been proved.
If anyone wants a free design simple to install just take all the drawings

Walt,
My Nanchang when I bought it was a CJ-6, not a CJ-6A. The engine was HS-6
(260hp) according to its data plate. I never found any oil in the top rockers
and was informed to make sure to keep them greased up. Only the CJ-6 was
produced starting in 1962. In December 1963 they started putting the HS-6A (285hp
and lubed top rockers) into SOME aircraft (than called the CJ-6A) on the
production line. There were a mixed bag of CJ-6 & 6As produced. My airframe was
built in 1969 but was a CJ-6 with the HS-6 (260hp) engine. I've only heard of
one other (CJ-6) coming into the US. Jim Plumly of SC has a 1962 CJ-6, the
oldest that I know of here in the states, however at some point it's engine was
changed to a HS-6A (285) making it CJ-6A.
I've tried on several occasions to get the production history of the CJ-6.
To no avail. At some point the Chinese use spot welding instead of rivets on
the fuselage. I've seen this on some airplanes produced in 1969 and 1972 but
not on 70 or 71. A real mixed bag too. I would like to find which batch in
the production got what modifications. Oh well, maybe someday. :-/

I have the proper tool with a gauge. The problem with these adapters
with Schrader valves is that you can't measure the pressure in the strut
BEFORE inflation. You are relying on air pressure to push the valve
open. The struts need to be inflated to the proper pressure while up on
jacks with no weight on the gear. Without the proper tool, one cannot
measure the proper pressure in the strut. This is particularly important
in the L-29 which has much higher strut pressures.
The proper strut inflation tool has a valve which screws onto the fill
fitting on the strut. You screw in the valve to depress the plunger in
the fitting, this allows strut pressure to be indicated on the guage. In
order to fill to the proper pressure you open your nitrogen bottle
(which is connected to the device) and allow the strut to fill until the
proper pressure is indicated on the gauge. Then you close the bottle,
then close the valve and depressurize the hose. Then you can SAFELY
remove the adapter from the strut.

This doesn't measure strut pressure just tank pressure. The question was
how do you measure the pressure in the strut BEFORE letting nitrogen in.

I would also like to point out the instructions described in this thread
for using this adapter.
>FILLING INSTRUCTIONS ARE :
> REMOVE METRIC FILLER CAP FROM STRUT, INSTALL TOOL, FILL STRUT, REMOVE
> TOOL
If this procedure were followed, one would have a 75 caliber projectile
with 700 PSI behind it as the poor slob was unscrewing the adapter.
If using one of these adapters, PLEASE make sure to depressurize the
adapter by depressing the Schrader valve until all nitrogen has been
depleted between the adapter and the strut filler plunger.

WITH A DUAL GAUGE SET ON THE NITROGEN TANK WITH A REGULATOR, ONE GAUGE
MEASURES TANK PRESSURE AND THE OTHER GAUGE MEASURES INLET PRESSURE GOING
INTO THE STRUT. THE INLET PRESSURE IS CONTROLLED BY SCREWING IN THE
REGULATOR CONTROL . IF THE PRESSURE IN THE STRUT IS LESS THAN THE REGULATED
PRESSURE GOING INTO IT, THE STRUT VALVE OPENS AND THE PRESSURE SHOWING ON
THE REGULATED GAUGE IS THE SAME PRESSURE IN THE STRUT. THIS TOOL WILL NOT
MEASURE STRUT PREASURE BEFORE LETTING NITROGEN IN. IT ONLY ALLOWS YOU TO
FILL THE STRUTS USING A STANDARD US NITROGEN SET-UP. THE REST IS UP TO THE
OPERATOR.

THIS TOOL THREATS ONTO THE OE STRUT FILLER AND DOESN'T HAVE ANY PRESSURE ON
IT BECAUSE THE OE VALVE CLOSES WHEN THE REGULATED PRESSURE IS LESS THAN
STRUT PRESSURE. SO TURN THE REGULATOR KNOB COUNTER CLOCK WISE TO LOWER THE
PRESSURE TO "0" PSI ON THE HOSE GOING TO THE TOO L BEFORE REMOVING IT. THIS
CLOSES THE STRUT VALVE.

Yaksters,
I'm replacing my fuel and oil hoses. OK, so now I have them out of the
airplane and disassembled. Problem is I'm not sure of the hose sizes to
use. I'm thinking Aeroquip 303 hose might work but not sure of the
correct sizing given the metric end fittings. Anyone got suggestions on
the correct size of the hoses? I'm replacing all the hoses so I would
need suggestions for all the different sizes.
Thanks in advance

Ernie,
I moved the database to a better machine last night, but screwed up on the
connection. Thanks for letting me know. It is up and running again.
To all RPA members (and non-members) - please let me know if you run into a
problem, I can usually fix the problem just about immediately, but since
this is my night time job I'm not always aware of a problem until I run into
it or you do.
Thanks for all your patience so far with the online store as well - Drew and
I are doing all we can to have it open ASAP.
Thanks,
Deon Esterhuizen.

You make my point. Without you guys we'd all be SOL. I presume you are NOT
supported by the factory--no support for you means no support for any of us.
We are all dependent on our/your suppliers--are they reliable for the long
term? If you (or anyone else) could advertise as being a factory parts
outlet we could all give a sigh of relief. That's as true for 52's et al as
CJ's.
I didn't know you had hose--fittings, too? I've been through that chase
myself and had to substitute US hose ergo my post. Thanks for the list.
If we get no factory support we might as well go buy Experimental built
Warner powered Monocoupes with Aeromatic props.
Maybe next year for ARS.

Subject: support
Jerry,
Your worry about being without parts support makes me smile a bit. I have
over 200K invested in CJ6 parts, engines, aircraft and props, my overriding
goal has been to stock a full spectrum of parts to support the entire
aircraft. While I can somewhat understand your fear, I also would ask you
to consider the fact that if I don't have everyone's support there simply
isn't enough money in this to pay me to do it. I just invested 3500.00 in
bulk hose to support the needs of both the yak and CJ guys, now I am
wondering if it was a smart move. I sincerely doubt that you would want me
to just stock the expendables and let everyone worry about the small parts
and pcs on their own. I have attached my parts list for your information.
(Items with * are out of stock) Need seals to repair the shuttle valves, I
got em, fluorescent bulbs for the cockpit lights, got em, the hardware to
attach the gear doors, yep, the skins for the gear doors, yes that too, the
list goes on and on. It take a huge amount of cash to stock all this stuff,
but when your on the ground because of a broken this or that I can normally
get you back in the air. My philosophy has always been the same, and that
is that unless the potential CJ owner feels that he can support the aircraft
he will not buy it, parts have been the backbone of the whole CJ6 community
forever and without them our aircraft will end up as hanger queens or
derelicts. I'll bet I have received 20 calls form various insurance
companies asking about my parts support. The only reason why you can buy
anything resembling low cost hull insurance is because of the availability
of parts to repair the aircraft in the event of an accident. Your post
seems to say that we need alternative sources of parts, but the truth of the
matter is that at this time there is not sufficient numbers of CJ's in the
US to financially warrant it. If you have two suppliers, both will starve
to death, but if one person has the support of the CJ community he will be
able to slowly grow the business until we all can accomplish what we need
and want. You will have a place where you can find nearly any part of the
aircraft at a reasonable price, and I will have a business that hopefully
someday will grow into a source of enough income to support me and my wife
in our retirement. Right now this is a hobby business, when worked in
concert with my floral business it all works, take the flowers away and it's
a no go. I have kept my prices low as possible, hell Carl Hayes buys all
his wheel and brake stuff from me, then marks it up and sells it to the Yak
52 guys. And no, I don't cut him a good deal, he gets just what any other
dealer/shop gets that's 10% off my published price list.
In short if everyone wants to use US hose and reinvent the wheel, I'll stop
carrying the hoses, both bulk and complete, same applies to seals and many
other small items. When my income drops to a point where this is no longer
holding it's own I'll fold my tent completely. Then at least for a period
of time there will be no one to keep the CJ6 guys in the air. If I come off
sounding pissed I am sorry, I am not. I am only a bit frustrated at the
guys that continually want to change something like the hoses (to US) and
not only pay more in the end, but end up having trouble mating up two hose
systems that were never supposed to be used together in the first place. At
last count I have over 200 different (complete with ends) hoses in stock,
over 50 meters of each size in bulk, so why in the hell would anyone want to
go to all the trouble to screw with US hose and metric fittings?.
Deal with Eaglet?? are you serious? Eaglet is nothing more than an arm of
CATIC, they stock nothing, have no knowledge of the CJ6, and cannot do
anything more than what the factory allows them to do. They will tell you
that only they can sell new CJ6's, well I will personally guarantee that I
can beat any price for a new CJ that they will give you. I tried to do
business with Fan and Eaglet, she shipped the wrong parts, charged me for
the correct parts, when I protested it took her over a full year to get the
correct parts ready to ship and then she had the nerve to tell me that
Eaglet did not have the money to ship the correct parts to me. I had to
hand carry the parts back to the states myself. When I got the parts home I
looked closely at them and discovered that they were not stainless steel as
ordered. Again I protested, this time she told me "You don't need stainless
steel plain steel is good enough" end of story in her mind, you don't need
it so shut up and go away!! So no Eaglet is NOT the answer. Maybe honest
Andrew? I don't even want to get into that topic.
Get hit by a truck, Well if that happens you can deal with my wife, she has
a full knowledge of the parts business.
Looked for you at Red Star. I intended to have the miniyak there but we got
screwed up with a fabric issue, the second chance was the brand new CJ6. I
flew commercial to Deer Valley to hang the engine and get it ready to fly to
ARS only to run head on into the FAA on a paper work issue which is still
unresolved. So needless to say I attended ARS as a gib thanks to the
kindness of Don Andrews and the new CJ still sits in AZ waiting for a N
number.
Hope all is well with you, maybe I'll see you at Arlington. Please excuse
me for bending your ear but this issue is near and dear to my heart...and my
wallet:>)
Always Yakin,
Doug Sapp

--> Yak-List message posted by: "John Fischer" <fish@ccis.com>
While doing an annual inspection on an L-29, I discovered a leak around the
schrader valve. While there is one-way check valve that would normally keep
the air from escaping, the leak was so small it prevented the check valve from
closing and allowed the leak to continue until the system was drained.
If you are using a schrader valve, I recommend bleeding down the pressure between
the schrader and the one-way check valve after filling the port to allow the
one-way check valve to work. Then the schrader valve works as an additional
safety.

Yes, definitely a mixed bag.
Of the 4 CJ's I imported from China in 1994 two were early 1966 models, one
1967 and one 1969. They were configured as follows:
1966 - CJ6 - with the 260 HP -6 engine and 260 HP air intake system
1966 - CJ6 - with the 285 HP -6A engine and the 260 HP air intake system
1967 - CJ6 - " " " " " " " " " "
" " "
1969 - CJ6A - The only one of the 4 that left the factory as a CJ6A - The
installed engine was one of the early greased upper rocker versions. The air
intake system was the factory installed 285 HP version.
Apparently the Chinese airforce used whatever engine model they had
available at the time. No doubt the earlier ones were eventually discarded.

Yaksters;
Just got a 52 in with cotton surfaces. I picked off a small piece from
an inconspicuous location and it crumbled as I rubbed it between my
fingers. I did the "thump" test and it seemed OK to me but I'm not an
expert by any stretch. I'm not mentioning names... (he reads this list)
but the owner wants to fly it this summer and wait to replace the
surfaces with stits until later this winter. My gut instinct is to
replace the cotton if only for peace of mind. Your opinions here would
mean allot to him. There's little history on the age of the cotton.
Other than the crumbling cotton finger test, the surfaces haven't been
properly tested. How should he test the surfaces? What are the
implications?
Thanks in advance

I checked the data plate on my Housai today and it had a Chinese symbol then a
- 6 printed on
it,
then either an A or 4 stamped beside it. Next to that was a serial number stamped
in, then
another
serial number stamped in above that. Below that, were Roman Numerals 1 thru V or
VI with blank
boxes beside each, presumeably for some stamp which never applied in any case.
Any idea what engine / hp this one is? Thanks.
