As a builder or potential builder you should manage your experimental aviation risk by researching, learning, and understanding.

Aviation and experimental aviation involve inherent risks. Therefore these links are provided for informational purposes only. Corvair engines are not certified or approved by the FAA for use in aircraft. The reader/builder therefore assumes the entire responsibility and liability for incidents of any kind involving the use of a Corvair engine they may eventually convert, build, buy, install or use in an experimental aircraft. Keep that in mind as you peruse these articles (which are often an immediate prelude to or post publication of the 2014 Conversion Manual). Head over to for many more articles.

The information located by the links presented here do not warrant to be complete or encompass all issues that builders face when converting Corvair engines for flight. This information is freely available via other links on the Internet, and the resources are hosted at, but is organized here by URL for specific categorical purposes.
