  1. Newly Overhauled Engine, No Existing Logs?

    I apologize for starting a discussion that wound up mostly about TBOs. I intended that only as an example, because I couldn't think of a better one. My original thought was what if an IA believed a discrepancy existed, which most A&Ps would not consider a discrepancy. If the IA hands the owner a discrepancy list with only that item listed, and the owner takes the plane to an A&P to have that discrepancy resolved. If the A&P doesn't think there is a discrepancy at all; thus nothing to repair, what would he, or the owner do? Ignore the discrepancy list and fly on? Naturally the smart method would be to have the IA talk to the A&P, preferably before making the discrepancy list, and come to some resolution. Or is this too crazy a hypothetical to even be discussing.
  2. Newly Overhauled Engine, No Existing Logs?

    I wonder what kind of wording an A&P uses, or if he uses any at all for some of the problems. For example, if you ran into an IA who decided that your plane was past TBO, and he would not sign off on that basis. I would suppose his "discrepancy" would read "engine past TBO". Then your (more reasonable) A&P looks at the discrepancy list and decides that doesn't make the plane un-airworthy. Does he just tell you "that is not a problem, and you should throw away the discrepancy list". Or would he make a logbook entry saying "I have examined the engine and determined it to be air worthy." I don't think that should be proper, as the logbook (as I understand it) should only list maintenance done, and since he didn't do any maintenance, there should be no entry. What would you A&Ps do?
  3. SB's and AD's

    The answer may be that it usually happens in reverse order. The factory issues an SB for a perceived danger. Then if the FAA considers it enough of a danger, they issue an identical (sometimes) AD.
  4. Over voltage!

    Sorry to hear that. My VR is going strong after several years. Glad I haven't had to try to find out if your experience is typical.
  5. Mooney N94MR- Paint Project

    Byron, I'm not really very familiar with automotive or aircraft paint. But I was of the opinion that aircraft paints were more expensive than automotive. Is that factual? Is there any downside to using automotive paint on a plane? If automotive paints are superior, why are the aircraft paint facilities still using aircraft products? Or do they?
  6. Over voltage!

    Sounds like the voltage regulator. Simple enough, and cheap enough to use as a diagnostic tool. Zeftronic regulators are the way to go.
  7. I don't suppose you ran a GAMI lean test. It would be interesting to see how the plug colors relate to that. It would also be interesting to see how the colors would relate if you installed GAMInjectors. Back when I was racing sports cars, my experience was that the colors on the plugs was very dependent on how the engine had been operated in the last few minutes before it was shut down. We typically ran the engine at full power, and immediately shut off the ignition, coasted to a stop and pulled the plugs. After I bought and set up my dynamometer, a friend on mine attached an engine (from an MG if my memory is correct.) After running it at full throttle and full load for a few minutes, we shut it down. The plugs (although well used) appeared brand new. Not a speck of soot.
  8. Stopped by the Mooney factory today.

    You really ought to go and look again. It is VASTLY different. Light, airy, clean, and a lot modern (not that I have anything to compare it to, other than the way it looked before). I don't know whether the Chinese owners are going to make a go of it or not, but I am very impressed with their apparent attitude. All the prior owners seemed to want to start building and selling airplanes, presumably to make money, right now. The attitude now seems to be "lets build a facility to make airplanes into the future".
  9. I don't know if mine is a G1, but it has three different size slots for cards. What are these things worth these days?
  10. Service Bulletin M20-088

    Yes and no. Our windows will crack if hit hard with a sharp object. But they don't shatter like glass. You have to keep hitting and breaking out pieces. I think (but do not know for sure) that it may be faster to get out the baggage door faster than breaking out a window. I have broken a window out, but I have not undone the baggage door latch from the inside.
  11. M20 F Fuel Selector Label

    Here is one from my plane. Won't be like yours, but maybe close enough to be helpful.
  12. M20k 231 exhaust

    Try Dawley. They can rebuild any or all parts. Fairly reasonable.
  13. Mooney N94MR- Paint Project

    Looking great. Keep'em coming.
  14. speed brake problem- quirky?!

    My plane is a 1982 K model with the speed brakes installed a few years later (my plane in in for an annual, so I don't know the exact year.) My maintenance records do not show any speed brake work until a few months ago.
  15. Oil pressure gauge weirdness

    If it were me, I would check and see if it does it on the ground. If so, plumb in another gauge and see if it does the same.
