If so it was from the commander group, I think the return address would reflect. CAREFULL how you open.

Don't know if it is going to help you at all but there you go anyway. Tom F. (Still looking for a 680FLP) ******************************************* --> Commander-List message posted by: "Scott Dickey" 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. ******************************************* ----- Original Message ----- From: Subject: Commander-List: accumulator for 500A > --> Commander-List message posted by: > > > i need an o/h of my accumulator. any suggestions? al hoffman > > ________________________________ Message 7 _____________________________________ Time: 05:21:54 PM PST US From: Chris Schuermann Subject: Re: Commander-List: accumulator for 500A --> Commander-List message posted by: Chris Schuermann alh1@juno.com wrote: > i need an o/h of my accumulator. any suggestions? al hoffman 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. chris do not archive ________________________________ Message 8 _____________________________________ Time: 06:11:50 PM PST US From: "Bill Bow" Subject: Re: Commander-List: accumulator for 500A --> Commander-List message posted by: "Bill Bow" What about these guys? http://www.aircraftaccessoriesofok.com/ bilbo ----- Original Message ----- From: Subject: Commander-List: accumulator for 500A > --> Commander-List message posted by: > > > i need an o/h of my accumulator. any suggestions? al hoffman > > ________________________________ Message 9 _____________________________________ Time: 06:33:49 PM PST US From: Chris Schuermann Subject: Re: Commander-List: accumulator for 500A --> Commander-List message posted by: Chris Schuermann 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 chris ________________________________ Message 10 ____________________________________ Time: 08:29:58 PM PST US From: RnJThompson@aol.com Subject: Commander-List: Re: Noise --> Commander-List message posted by: RnJThompson@aol.com 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.

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 ________________________________ Message 12 ____________________________________ Time: 08:55:12 PM PST US From: YOURTCFG@aol.com Subject: Re: Commander-List: accumulator for 500A --> Commander-List message posted by: YOURTCFG@aol.com 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
