Posted: Wed Feb 21, 2018 3:47 pm Post subject: Air tanks

We have been trying to discover the root cause of many of you reporting that you are getting a very short life (some less than a year) out of the QSF-2A and the 12-5522-00 valves used in the CJ6, which are the same as the 3 and 5 port valves used in the Yaks.



Recently a customer who was upgrading to our new CJ6 stainless steel main and emergency air tanks reported that when he removed his stock steel Chinese tanks he found about a cup of water in each tank.Â  His tanks were also very rusty.Â  He remarked that he has been religiously maintaining his stainless desiccant filter on a 8 hour basis, and while the color of the desiccant had changed the filters had not been found to beÂ  wet at any time.Â  Â This would tend to make me believe that the water in the tanks was there BEFORE the stainless filter was installed.Â  As we all know there are only two things which "kill" these valves;Â  water and grit.Â  Water rusts the steel plate, grit abrades it, and in a short time it is leaking.Â Â   Â I am guessing that the rust particles and or water from his tanks is what has been damaging his valves.

We are now testing a "final filter" which is a very small filter which connects directly to the 3 or 5 port valves "air in" port.Â  Dee Grimm has agreed to install one in his aircraft in tandem with the installation of a new QDF-2A.Â  This filter should remove any rust particles and grit from the system before it has a chance to enter the valves, but before it will be 100% effective the air tanks should be drained and checked for water because this is NOT a desiccant filter and will not remove moisture.

We are recommending that both air tanks be drained at the annual Conditional inspection.Â  We will include a drain plug crush seal in our conditional kits in the future.





Please note that our office will be closed Feb 23rd through the 3rd.Â  It's 0F here and it's time for a sun break!!





Best to all,

Doug and Kathleen.

Here in New Zealand while we don't have the freedom that you guys in Trumpville have, occasionally our Civil Aviation Authority comes out with some gems of sensibility and wisdom.



It is an AD here to remove and drain our air tanks every 50 hours.  Every year we must also clean out the inside "with a suitable method".  I usually slosh a hals a litre or so of methylated spirits around inside them leave them to drain and dry while I do the rest of the annual.



Last time I did this job I was grumping at the stupidity of having to do all that work to drain the  few drops of water out of my tanks, but after reading Doug's post I think I have changed my mind.

your flap actuator is on the way back. 

  

I guess I need two SS main air tanks when you get a chance.

Appologies.  I wasn't trying to make a political statement, merely a humorous one.

No apologies needed because just as soon as the nitwits in one of either party talks of grounding our aircraft, he too will get political here. I sure as hell will. I caught that island humor.

No offense taken Bro. 

Donâ€™t know what a safe space is. Trumpville is kinda funny.
