Does any one know an acceptable leak rate for the Pitot system?Â  Mine is pretty bad right now.Â  If I pressurize the pitot so that airspeed shows about 130kts, it leaks down about 7 or 8 kts/minute.

 



What is an acceptable leak rate in terms of kts/minute (or should I say minutes/kt)?

I should say this is not an IFR plane.



Thanks,

That's not bad at all. Our static shop always says to remember that pitot is "an infinite column"--that is, it's always being refreshed. A good rule of thumb would be that if you can't easily see thatÂ it's dropping then you're doing OK. If the needle (or EFIS)Â movement catches your eye it's probably too much.Â  



If you have a mechanical indicator, remember to disconnect the airspeed static when you do the altimeterÂ check.Â

Dave Salor has it right, but just to add to that..  The "pitot-static test" is actually just a "static" test.  There are no standards the pitot portion must pass.  They always seem to test it, but it is just optional for IFR.  For VFR, they don't even test the static system, it is just a transponder test. 



You wouldn't want it crazy out of wack, but it sounds like you are fine.
