CJ6 with Housai, It took a while to start, initially main air gauge showed 32 air and by the time it started was at about 18.

Took off , flew for 1 hr and it charged only to 25, no more, (usually it charges to 40, in just a few minutes) actually was dropping from 25 towards the end of the flight.



Landed it with about 20 (by the time I used gear, flaps and brakes),  then closed the main air tank valve, in the 5 minutes it took me to taxi back to my hangar with the main air tank closed, it charged to 32.

So I suspect the compressor its doing its job.



Filled up with scuba tank, and main air tank is holding air.



Any ideas?

Another member suggested cleaning and inspecting the snot valve, and air compressor check valve, which I will do.

With main air valve closed while you were taxing back to hangar you were only sending air to the lines and the emergency bottle. If the emergency bottle was full then you were only pressurizing the airlines which doesn'tÂ  take much. FYI.Â

Classic symptom of the snot valve not being closed tight.

Does the Housai compressor has a shear coupling?

Yes.  There 2  pins on the shear coupling.  Make sure the system from the bango fitting to the regulator are tight and not leaking.  IF you must take off the compressor, I have found it easier to : 1. Takeoff the center exhaust pipe section.

  2. Take off the right magneto -  DO NOT rotate the mag nor the propeller after that.

  3 . Remove the compressor.

  4.  Replace the coupling or replace the shear pins.  It would be easier the replace the coupling.

  5.  Reinstall in reverse order.

  

 

  For me removing the mag makes the nuts holding the compressor much easier to get to.  Just do not rotate the mag or prop from this point on.  You change the timing if you do.  This might take you 2 hours to do.  Most of that time will be removing the nuts on the compressor.  You could also make it easier by having the correct tools.  You can grind down some open end and box wrenches to get into the close quarters on the nuts on the top back of the compressor.

Youâ€™re making pressure, just not keeping it...I start with the easy stuff.  For context, how long since last flight?  Is it significantly colder than last flight?  Did you disturb anything since last flight (repack dryer, open any connections, move any hard lines)?  How fast does the pressure drop on deck, with tank valve closed (minutes/hours/days)? and main tank was holding air its pressure when valve is closed?



Looking for issues with seals, valves, b-nut/flares and cracked hard lines typically.  (Knock on wood) my compressor has never been an issue, not saying it canâ€™t, but plenty of the above issues to trace before jumping to the hard stuff.



Seals can take a set or dry out when they sit too long between flights.   Leaks in actuators and their associated selector valves are not unusual.    Grit is the enemy of selector valves...failing actuators can provide it.  If your dryer isnâ€™t drying (if you have mist at wing root snot valve it may be time to repack dryer) moisture in system can rot everything, including sealing surfaces, and provide more grit.



Hard lines often crack on the inside radius of something stressed...either by disturbing it during maintenance or flexed in normal ops (e.g. compressor output line)...and can be hard to find because the crack may stay closed until stressed.  â€œAncientâ€ hard line is more prone to cracking.



B-nuts and flares leak when cross threaded or flares are cracked when b-nuts are over tightened or â€œcoaxedâ€ into alignment.



In a quiet hangar, get some spray soapy cleaner (or high tech with an HVAC ultrasonic leak detector, someone here probably has a favorite).  Pressurize the system, listen for leaks in the cockpit (usually gear/flap actuators or valves), at the firewall and at your fill port.  Spray soapy cleaner on anything youâ€™ve recently disturbed (lines/fittings) and if nothing obvious, all the firewall lines/fittings and fill port.  Cycle selector valves, ideally up on jacks for gear!  Does it leak less/same at neutral?  Is the starter valve healthy (strong â€œpopâ€ on/off with pressure on)? 



Thereâ€™s plenty more places to look, but those have been my top tens...sometimes you get lucky and a few cycles clears grit or re-lubricates a dry seal.



If you havenâ€™t already, buy some hard line tubing stock, a tubing bender and cutter, a flaring tool, and from Doug, b-nuts and flare inserts (ferrules?)... and spares.



Cheers, Rich

Thanks for your detailed reply.

Last annual (first to me) we replaced all the air valves.



I fly it often, 2 or 3 times per week, last flight was 4 days ago, temps about the same, high 40s.



Nothing was changed since last flight

Lately the snot valve has been very hard to open.

Surprisingly after this flight was easy to open (maybe because not much air was left?)  when I opened it had a lot less pressure than usual.



Have had an air leak in the rear flap lever, after I close the main air tank, it looses air quick, 15 minutes and its gone, its been like this since I bought the plane.



Main air tank is holding air.

The air system is the heart and soul of the airplane after the engine. Â 

If your new to air based control systems I would suggest reaching out to Craig Payne.Â  He owned a CJ and wrote a great information piece on the air system with photos and trouble shooting information as well. Â 

It is a good write up that will help you understand the system better if you need the assistance. Â 

If you have a good understanding.Â  His info may shed some light was well. Â

I've been dealing with a similar issue, on mine. I can charge to 50 ATMs and go fly and the compressor can't put the air back to anything higher than about 38 ATMs so I'm thinking I'm dealing with a tiny leak in the UP side somewhere. Haven't been flying for over a month due to waiting on parts, but I'm going to try and follow advice given on another Red Star site to soak the felt filter on the top of the compressor and see if it helps seal the rings. If it does, then I'm looking at a weak compressor. If not then it'll be leak detection time.



As for the snot valves. Mine started to become harder to open as they gunned up and finally started to not seal properly when closed. So I replaced mine with swagelok 1/4 turn stainless ball valves..SO MUCH NICER!!

Holding system air pressure for days with main valve closed can be achieved by those especially pious, for most it only occurs on odd leap years.  A leak down in minutes means what you did at last annual didnâ€™t solve all the problems. Before chasing anything else, Iâ€™d start with what you know is a problem...flap system.  Things that rarely get exercised will get pissed off when disturbed after a long rest (like at annual when you cycle rarely used items) if youâ€™ve isolated rear cockpit flap valve as a leak source after verifying same leak whether rear flap valve up/down/neutral you might get lucky and clear some grit with enough valve cycles.  If not, try a new valve or remove valve and cap the rear valve lines. 



A little soapy solution on snot valve overboard discharge while system is pressurized will tell you if that is leaking.



If thereâ€™s still residual leaks after solving these, Iâ€™d next soap every connection, valve nipple and line disturbed when you changed things at annual...and sometimes, even new replacement items leak.

Iâ€™d also add that these planes are of an age and distance in time from their maintenance by the military that pinhole leaks in random portions of the tubing are starting to pop up far more often than, say, 20 years ago. 



I donâ€™t believe that the tubing of the pneumatic system has a per-se life limit, but itâ€™s neither perfect nor forever-lasting.

That valve swap looks like the way to go. Â 



You donâ€™t have record of the part number for that valve handy do you. ?

You replaced the â€œsnotâ€ valve with a swagelok?  Or do you mean the main air valve. 



Removing, disassembling and flushing out the snot bottle fixes many â€œnot charging â€œ to the break over preset pressure of the pop off/ pressure relief valve problems.

Donâ€™t forget the banjo fitting. It can get gummed up and also be loose. And easy check.

Yes, that does look very clean.  I missed the pictures.  However, that does not change my comment about removing and flushing out the shot bottle.

He replaced the valve on the snot valve.  

Take a peek at the attached picture.  

Looks pretty clean.

 You replaced the â€œsnotâ€ valve with a swagelok?  Or do you mean the main air valve. 

 

 Removing, disassembling and flushing out the snot bottle fixes many â€œnot charging â€œ to the break over preset pressure of the pop off/ pressure relief valve problems.

I can charge to 50 ATMs and go fly and the compressor can't put the air back to anything higher than about 38 ATMs so I'm thinking I'm dealing with a tiny leak in the UP side somewhere. Haven't been flying for over a month due to waiting on parts, but I'm going to try and follow advice given on another Red Star site to soak the felt filter on the top of the compressor and see if it helps seal the rings. If it does, then I'm looking at a weak compressor. If not then it'll be leak detection time.

Your snot valve sealing brass â€œconeâ€ may have a ring worn into it which prevents a proper seal and will always leak once itâ€™s like this.  Swagelok replacement valve is the answer and can also do the Main and Emerg valves and check valves on the firewall as well.  Guaranteed to fix majority of pneumatic issues.  Isolate and/removing of the rear gear and flap valves will solve the rest...see pic below.

Good luck- Hoot

You are correct. Â 



My system ran better after soaking my snot valve in AV gas.Â  Per your instruction

         Yes, that does look very clean.Â  I missed the pictures.Â  However, that does not change my comment about removing and flushing out the shot bottle.
