Just some background info. This aircraft uses a Safe Flight Lift Detector. fancy stall horn. Overhaul cost $1800. If anyone has experience where it is going off a lot in flight or when you are sitting on the ground this is the culprit. Once you loosen the stall warning switch you see that just tinkering with the screws that tighten the switch to the wing it will set off the stall warning. Called the company and they said that is a common problem and the switch is bad. Just send it in for O/H. Th
