The purpose of this thread is to provide quick access to the regulations regarding aircraft certification. In the U.S. FAR 23 has a considerable amount of data regarding the loads and limitations that aircraft should be designed around. For designers this is an invaluable resource. If you are thinking about designing your own plane I can guarantee you that the more experienced members of this forum will sooner or later tell you to look up FAR 23.
In keeping with the international nature of this forum I will also list links to other countries regs as they are made available to me. If you post a link and don't see this top post modified to include your link please pm me. I do have a life so it might take a day or 2. Once links have been added posts will be deleted to keep things uncluttered.
Thanks to Jake for making this a sticky and for giving us this great site.
