Subject: Allegro-List: 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,

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?

P.s. was good to see the allegro folks with a display at OSH
