Greetings All! A while back my Yak 52 was test flown and at one point, the
emergency air was opened. Now the air system is reluctant to switch back
over to the primary system and there's an audible hiss from the relief
valve immediately below the front seat / right side every time I open up
the main air valve after recharging. This valve has a large escape hole on
top and if I seal it w/ my thumb it seems to close the system and all is
back to normal. Unfortunately, everytime I open the master valve I go back
to square one w/ this process. I was told by one source that one of my
actuator shuttle valves is malfunctioning. But which one? I purchased an
ultrasonic listening device in an attempt to trace down the source of
the leaks. In "tapping" lines on all 3 gear, the audible leak seems to
resonate through all lines. It DOES seem to be noticably-louder on the nose
gear line - or is this simply because that point is physically-closer to
the floor-mounted escape valve? What do I do next? Anyone w/ experience in
this area would be a welcome sight on my screen. Thank you for your
assistance and patience, guys!

Have you completely drained both air systems? I'm more familiar with the C
J but I recall that the Yak system has to be completely drained before it w
ill switch back over from the emergency system.
