We recommend that before you build your aircraft you contact the nearest FAA Manufacturing Inspection District Office (MIDO) or Flight Standards District Office (FSDO).   You may discuss with us the type of aircraft, its complexity, and its material.  You should provide a three-view sketch, drawing, or photograph of the proposed aircraft project and the date you think you will finish.  We will give you any guidance (to include any forms) and information necessary to ensure you thoroughly understand the FAA regulations that apply to your project
