Hi, I was doing a stall series the other day and my stall warning horn didn't go off prior to wing rock and nose drop and effectively provided no warning of impending stall. It chirped once but it happened just as the nose was breaking. Repeated a couple times and same effect. On deck, the stall warning horn checks fine when the tab is lifted to the stop. It works every time on the ground and I can't get it to not work so don't think there is a wiring or actuator problem. One more piece of data, I had the plane painted and prior to the painting the system worked just fine. So, could it be possible the paint shop installed it improperly and is this something I can adjust? Could it be installed backwards? Or upside down? The tab actuates the horn when when you lift it up and it springs to the down position and turns the horn off. Before I ask someone to bend the tab is there something I could be missing? Thanks for the help.
