Anyone using different woods should download A.C. 43.13 from the FAA web site. It lists several types off wood that are acceptable to certified planes and gives some other good criteria for selecting wood.

Someone recommended sassafras, and I have some experience with it. But meeting the many criteria is another issue. I've built a three planes, and they haven't broken yet. That doesn't mean they were as light as they could be or that they meet the design criteria. Many builders have substituted other woods, and they were maybe just lucky. I use CERTIFIED SPRUCE for critical areas. Like spars. You cannot find wood of that quality unless you have an "in" with someone in the business, and you're not likely to find it at a "lumber yard".

Honduran Mahogany...................34lbs/cu.ft >>>>>>>> Thank you for opening this avenue - I have access to a variety of woods that I would never even have considered, eg. African Teak, Mahogany, Rosewood and Kiaat. Where can I find more info on testing and suitability? Are you prepared to discuss this off-net?
