    regarding "overfill" - I agree. Did you believe the pressure guage? Maybe it is in error and indeed the pressure was higher and you did have an overfill situation. OTOH could also be O-ring deterioration. If pressure was "down" maybe that is why it was. -

    Subject: exhaust clamp
    Gentlemen, I have noticed that my exhaust collector clamp is getting pretty tired. I am looking for some replacements. The part# is 5610130-31. This is the clamp that attaches to the rear of the exhaust headers where they sit in the front of the augmenter tube. It looks like three clamps that have been brazed together in a triangular shape and connects the three headers to reduce vibration. My installation is on a 560 A, If you have any of these or are aware of a source please let me know. Thanks _scottmain2003@aol.com_ (mailto:scottmain2003@aol.com)

    PRESSURE CAN COME DOWN AS A RESULT OF A NITROGEN LEAK ANYWHERE IN THE SYSTEM. MOST NITROGEN BOTTLES HAVE GAGES WHICH ALTHOUGH NOT CALIBRATED CAN BE USED FOR A ROUGH CHECK OF YOUR GAGE WHEN FILLING. HYDRAULIC FLUID IN THE PNEUMATIC SYSTEM IS A POSITIVE INDICATION OF A LEAK IN THE GEAR ACTUATOR.(HYDRAULIC/PNEUMATIC). ----- Original Message ----- From: Robert Feldtman<mailto:bobf@feldtman.com> To: commander-list@matronics.com<mailto:commander-list@matronics.com> Sent: Monday, February 04, 2013 8:10 AM Subject: Commander-List: Re: Commander-List Digest: 2 Msgs - 02/03/13 <bobf@feldtman.com<mailto:bobf@feldtman.com>> regarding "overfill" - I agree.

    THE GAGE I REFERRED TO IS THE ONE MEASURING NITROGEN PRESSURE. ----- Original Message ----- From: David Owens<mailto:dowens@aerialviewpoint.com> To: commander-list@matronics.com<mailto:commander-list@matronics.com> Sent: Sunday, February 03, 2013 7:47 PM Subject: Re: Commander-List: Pneumatic leak? iF i AM NOT MISTAKEN, the gauge you are referring to is the blow down bottle pressure, right? The one on the bottle in the baggage compartment? It has been our experiance that when the blow down bottle is over filled it can cause all kinds of problems like this... ----- Original Message ----- From: Dave Gerrish<mailto:virginia.gerrish@verizon.net> To: commander-list@matronics.com<mailto:commander-list@matronics.com> Sent: Saturday, February 02, 2013 2:33 PM Subject: Commander-List: Pneumatic leak? Hello fellow Commander enthusiasts. I have been reading the back and forth information on the site for several years but have not chimed in. Until today. I own one half of a 500S, N47AC, based in Warrenton, Virginia KHWY. My partner, Ken Hyde and I have had an interesting time over the last several years with the landing gear actuators. Here is the latest. Earlier in the week I went down to the hangar to preflight and the pneumatic gage was at 150PSI for no known reason, so I pumped it with nitrogen back to 300PSI. Did not fly the airplane. Today I am back in the hangar and there is a big puddle of hydraulic fluid on the floor under the left nacelle. Turns out the reservoir is showing way past full and it looks to me like the fluid just went out in the overflow tube in the reservoir on to the floor. OK, so I am thinking one of the pneumatic main gear actuators must have some kind of internal failure that allows the nitrogen to push the hydraulic fluid into the reservoir and when it gets full, onto the floor it goes. Ken and I I'm sure will research this but I am wondering if others have had this kind of thing happen to them? I am also wondering if others just get rebuilt, yellow tagged actuators, or if they buy new ones or if they pull the darn things apart and fix them themselves, assuming they meat dimensional specs. Any thoughts or comments would be greatly appreciated.
