Guys and gals I am to the point in the plans where you are told to install the stall warning system on OP46. As I understand the leading edge skin didn't used to come already punched for a lot of things. I was going to leave this out as I think AOA is a better solution. However, the skin is punched for the access plate and drilled for the rib/ vane locating holes. Did anyone not install the system? If so, did you just put rivets in the holes mentioned? Thanks
