    Subject: Stall Warning Failure
    From: "ledson" <ledson@oneil.com>
    I'm trying to find out if anyone else is have this problem with the Stall Warning system on their Allegro 2000. Last Saturday during cruise flight, the stall warning horn started sounding. I was at approximately 95 mph. The stall warning light did not come on and there was not any changes in the AOA. Upon landing, the stall warning horn stopped sounding and the stall warning light came on like it normally does when landing. I checked the feed tube to ensure that there wasn't anything blocking it and then tried several more takeoff and landings with the same results. I'm assuming that it is either a failure of the stall warning control board or the ASI. Right now I'm at a loss on how to proceed. I don't have a wiring schematic of the stall warning system and without one I'm not sure what's next. So if anyone has any experience with this system I would certainly appreciate your advise. Thanks, Larry Edson N4362C Read this topic online here: http://forums.matronics.com/viewtopic.php?p=379587#379587

    I wouldnt think the ASI is involved unless we have a really unusual system. Maybe whatever control board it has or a wiring short to the horn? Brad N221FA. Bismarck ND P.s. was good to see the allegro folks with a display at OSH Brad Kramer / VisionTech (701) 222-3009 ledson <ledson@oneil.com> wrote: I'm trying to find out if anyone else is have this problem with the Stall Warning system on their Allegro 2000.
