To be eligible for an experimental airworthiness certificate, satisfactory evidence must be presented to show that the aircraft was not assembled from completely prefabricated parts or kits. The FAA recognizes that amateur builders cannot be expected to have fabricated every part that makes up the aircraft and that some parts will be acquired from commercial sources. Items such as engines, engine accessories, propellers, rotor blades, rotor hubs, tires, wheel and brake assemblies, instruments, and standard aircraft hardware, including pulleys, bell cranks, rod ends, bearings, bolts, rivets, hot air balloon burners, and fuel tanks, are acceptable and may be procured on the open market.
Every builder needs to maintain a builders log to document the construction of the aircraft. This will be your proof to the FAA that the aircraft was amateur-built. Simply record the date, time worked, and what was done each time you work on the project.
All of us are aware that the aircraft we fly must have an airworthiness certificate. Usually this certificate will be a Standard Airworthiness certificate issued when the aircraft is manufactured. What about experimental airplanes that are constructed by an individual?
The most common use of experimental applies to a classification of an airworthiness certificate used for a custom built airplane. This is different from the airworthiness category assigned to an airplane that is mass produced by a manufacturer which is then sold to the general public. I will explore the exact meaning of the word experimental later in this article. I will attempt to clarify the confusion that exists and to simplify the regulations as they apply to building an airplane.
Subpart D applies--means the person who is responsible for the operation and maintenance of the aerodrome. C; or.

The statistics were in line with what the Safety Board found in its recently completed study covering the year period from to titled "The Safety of Experimental Amateur-Built Aircraft. Included with the powered fixed-wing aircraft were 97 helicopters, 75 gyroplanes, 16 gliders and four balloons. The Safety Board says E-AB safety could be improved if the FAA had tougher documentation requirements for airworthiness certification when an aircraft is first built, more stringent flight-testing requirements, improved access to transition training for pilots and greater FAA support of efforts to facilitate training.
