Tom, I don't think so. If so it was from the commander group, I think the
return address would reflect. CAREFULL how you open.

I notice you did not get a public response earlier so I had one item from
this past May and I have posted it here in it's entirety.
Don't know if it is going to help you at all but there you go anyway.

Hi Everyone,
This is just a follow up on my efforts to get my accumulator charged and
working properly. Now you are all probably thinking, What a loser. This guy
doesnt even know how to service his hydraulic accumulator. So for the one
other Commander owner out there who doesnt know how to do this, here are
the tricks I learned over the last week.
1. Connect 600 psi nitrogen to the accumulator fitting and make sure the
fitting is open by turning the locknut counterclockwise at least 2 turns.
Leave the nitrogen source ON and the regulator set for 600 psi +25 / -0 psi.
2. With all power OFF (engine driven and aux pumps), move the flap handle
from the neutral position up or down VERY slowly until you hear the pressure
bleed down to zero (you can see this happen on the gauge and you can hear it
through the flap valve). It turns out the flap valve has a bleed port which
bleeds pressure just before going to the flap UP or flap DOWN position. If
you move the handle slowly, you will hear pressure relieve and see the gauge
go to zero 1/4" or so before getting to the flap UP or DOWN position. Now
the piston in the accumulator is at the end of its stroke with 600 psi
nitrogen on one side and 0 psi hydraulic fluid on the other.
3. Check your accumulator for internal leaks. Now that you have 600 psi on
the accumulator, you can see and hear if the piston o ring is leaking. If
you hear anything then open the hydraulic fluid reservoir to see if there is
any foam or bubbles. If there is nothing, proceed to step 4. If you see
bubbles and the thing is hissing away, take a deep breath and cancel any
upcoming trips. The good news is that you can get the whole accumulator
overhauled by Higher Planes for just $1800. And since those accumulators
just jump in and out practically by themselves, its a real bargain! But if
you need it done, they have a FAA approved overhaul for that component
(along with other commander stuff like power brake valves).
http://www.higherplanes.com/
4. With the nitrogen still ON, tighten the lock nut on the fitting and
remove the nitrogen fill hose (don't forget to turn off the Nitrogen before
removing the fitting - 600 psi is A LOT of pressure).
I believe this is the first time I've flown the airplane with the
accumulator serviced properly. The hydraulic pressure gauge now barely
moves, even when actuating the flaps, brakes, etc. It used to snap back and
forth during flight and especially when using the system. When serviced
properly, the accumulator does and excellent job of dampening the pressure
in the system, to the point where there is almost no pressure fluctuation at
all. If your gauge moves much at all or if you see any rapid movements,
chances are you have flat or low accumulator pressure.
The other trick to doing this properly is finding a nitrogen source that can
go up to 600 psi. Almost everyone has a N2 bottle with the welder style
regulator but most of those cannot regulate to 600 psi downstream pressure.
I decided to look for the components to buy and I really had to search for a
regulator that could regulate to 600 psi. Most regulators that I saw have
maximum of 350 - 450 psi regulating ranges. They maybe go a little higher
but you're lucky if your mechanic has the proper rig. If you are planning to
build your own rig, plan on spending about $500. Here are sources for
everything you will need:
1) 110 cu foot or larger N2 bottle - any local welding shop. About $200
buys the bottle and refills are cheap.
2) 0 - 1500 psi high pressure regulator. Available from
www.weldingsupply.com. Item # 3200300, about $230.
3) High pressure hose and N2 ground service fitting. Available from Hoses
Unlimited (510-483-8520). They will make up a hose of any length and sell
you the fill fitting as well. The regulator terminates in 1/4 NPT female so
you want a hose with 1/4 NPT male on one end.
So that's it. Anyone who is ever in the LVK area stop by for a free N2 fill.
* Credit goes to the service manager at DownTown Airpark for telling me
about that bleed port.

al,
Someone wrote a post a while back. I didn't keep the post, but I did
bookmark http://www.higherplanes.com/
Started to check the chatlist archives, but they're so full of junk
posts that I gave up. (I know I don't run the list any more, but it
would be a courtesy if everyone tried to follow the rules Jim set up)
The commander web site has a link under the maint. section for
accumulator repairs, but the link appears to be currently broken.

just fyi,
I've been using a place called "Quality Aircraft Accessories Inc" in
Tulsa OK recently. I've been impressed with the quality of their work
and they seem to have reasonable prices. They do hydraulic pumps,
alternators, fuel pumps, prop governors, turbos, mags, , and most other
accessories. They'll even do a one-day turnaround on many items if
needed. I recently took a prop gov in for overhaul and they had it back
in my hands in 48 hours even though I didn't request a quick turn. They
have a very well equipped and clean shop and appear to have lots of
people with substantial knowledge there.
Their number is: 918-835-6948

Hi All
I am having a great deal of fun trying to get a noise certificate from our
local aviation department. Apart from the fact that all the rules apply to
transport cat aircraft. Its like talking to a brick wall. It looks like I am going
to have all the noise testing done.
ANYBODY KNOW HOW TO SHUT A PAIR GSOs UP?
I am open to all sugestions.
I feel that this might help us in the future as almost all countries are
starting to hassel us poor unfortunate folk who happen to drive these geared
wonders.
My thoughts so far involve
1) Perforated stacks inside a slim shroud.
2) Combining three stacks into one muffler
3) Lining the inside of the augmenter tube with a layer of fibre or mesh.
Regards
Richard

Contact Dick Ward at he Twin Bonanza Ass (_www.twinbonanza.com_
(http://www.twinbonanza.com) ). There was an article a few issues back about a Twinbo
with mufflers in a Scandinavian County. It wasn't cheap, but I guess it worked.
Or, how about a revolution. I think we need one here as well!! jb

Try Commander Aero, ask for Gary Kromer 937-885-5580. They are pretty
simple. Unlike the old Commanders with a diaphragm type accumulator, these have
only a couple of "O" rings. jb
