Dear Mooney owners! Hope you can share some light on my issues. I have a 2001 Mooney Ovation with 2100 hours. It has steam gauge. I replaced the vacuum pump 2 years 200 hour ago, when after landing with my CFI the AI tumbled completely in matter of seconds. A few weeks ago I was noticing during flight the vacuum pressure indicates low like 4.0inHg gradually dropping to 3.5inHg after 2 hours of flight. My mechanic did various things like cleaning filter, tighten regulator which helped increase the pressure by like 0.3inHg. Now a few hours of flight later, it drops again now the vacuum gauge is constantly reading 3.0inHg (I suppose this is the lowest the gauge can go?) However my AI, HI, and autopilot all works perfectly fine (in VFR condition I am flying). I just wonder, is my next step replace the vacuum pump or what? What would be the lowest possible cost including install labor to get rid of vacuum? I just got a quote for Aspen E5, $16000 including install labor. Very expensive! -
There's no harm in flying (VFR of course) with a failed vacuum pump, is there? My mechanic is out of town and I need to get the plane to and from a spot an hour away.
