Chris, 

Check your static probe under the wing still has the black “plug” in place , can get knocked of easily, result is ineffective asi ... ( you need a pressure differential and this effectively cancels it out ) ..symptom is taxi test that shows extreme asi lag .. 

disconnecting static line restores asi ... ( removes the balancing air stream ) ...



Slight air leaks in asi feed do not create the same ( massive ) effect.



The actual flow when you try to blow through is also relatively high resistance in normal operation .

 Evening All, I am preparing a UK built (2007) Europa XS tri-gear which I purchased last year for a permit check flight. The aircraft has not flown for 7 years. I believe I have a leak in the pitot tube system. Pitot and static lines passing through the  fuselage to the instrument panel seem to be made of semi-opaque hard plastic tubing approx 7.5mm OD and use 'push-fit' connectors. An adaptor connects the push-fit connector to standard ?6mm flexible clear tubing to the flight instruments.

 Is this a typical arrangement in Europas and where would I source the larger tubing and push-fit connectors? Many thanks, Chris

A very belated thanks for your reply Kevin.

Problem now sorted.

Test flight very soon!
